TY - JOUR A1 - Müller, Carsten A1 - El-Ansari, Kareem A1 - El Ansari, Walid T1 - Cross-Sectional Analysis of Mental Health among University Students: Do Sex and Academic Level Matter? JF - International Journal of Environmental Research and Public Health N2 - University students’ mental health and well-being is a growing public health concern. There is a lack of studies assessing a broad range of mental health domains by sex and academic level of study. This cross-sectional online survey of BSc, MSc, and PhD students (n = 3353, 67% female) enrolled at one university in Germany assessed a wide scope of mental health domains, covering positive (i.e., self-rated health, self-esteem, student engagement) and negative aspects (i.e., perceived stress, irritation, and screening positive for depression, anxiety, comorbidity, and psychological distress). We evaluated differences in mental health by sex and academic level. Overall, although self-rated health did not differ by sex and academic level, females and lower academic level were associated with less favorable mental health. Males reported higher prevalence of high self-esteem, and higher engagement (all p ≤ 0.04). Conversely, mean perceived stress and cognitive/emotional irritation were higher among females, as were rates for positive screenings for anxiety, anxiety and depression comorbidity, and psychological distress (p < 0.001 for all). Likewise, lower academic level (BSc) was associated with lower rates of high self-esteem (p ≤ 0.001), increased perceived stress (p < 0.001), and higher prevalence of positive screening for depression, anxiety, comorbidity, and psychological distress (p ≤ 0.002 for all), while higher academic level (PhD) was linked to increased student engagement (p < 0.001 for all). Although the effect sizes of sex and academic level on student mental health were modest, these findings support a need for action to establish and expand early detection and prevention programs, on-campus advisory services, and peer counseling that focus on the sex-specific and academic-study-level-specific factors, as well as mental health and career development resources for students. Academics and policy makers need to consider multipronged intervention strategies to boost confidence of students and their academic career.

While rehabilitation clinics support patients in coping with the disease, studies evaluating an inpatient rehabilitation program on promoting physical activity (PA) and health-related quality of life (HRQoL) are missing. Methods A 4-week inpatient rehabilitation program was prospectively evaluated. One hundred fifty patients with leukemia or lymphoma (N = 86), brain tumors (N = 38), and sarcomas (N = 26) were enrolled on average 17 months after cessation of acute medical treatment. PA amount and cadence (indicating the intensity of walking activity) using the StepWatch™ 3 Activity Monitor and HRQoL global and physical well-being scores using the KINDL® questionnaire were assessed before, immediately after, and 6 and 12 months following the program and analyzed using multiple linear mixed models. Results Significant effects on PA were only found at 12-month follow-up for amount and cadence variables (all p < 0.05). While leukemia and lymphoma patients revealed the highest PA level throughout the study, rehabilitation effects were more pronounced for cadence variables in brain tumor and sarcoma patients. The rehabilitation program had immediate (t = 4.56, p < 0.001) and sustainable effects on HRQoL global scores (6-month follow-up, t = 4.08, p < 0.001; 12-month follow-up, t = 3.13, p < 0.006). Conclusions Immediate and sustainable increases in HRQoL indicate that a 4-week rehabilitation program is beneficial for improving psychosocial well-being, while the significant increase in PA levels could be related to general recovery as well. The lack of a control group hampers the evaluation of the rehabilitation program on promoting PA levels in pediatric cancer patients.

The aims of this studywere to evaluate effects of kinesiotape applications with regard to shooting and throwing performance in 26 amateursoccer and 32 handball players, and to further investigate if these effects were influenced by the players’ level ofperformance. Ball speed as the primary outcome and accuracy of soccer kicks and handball throws were analyzed withand without kinesiotape by means of radar units and video recordings. The application of kinesiotapes significantlyincreased ball speed in soccer by 1.4 km/h (p=0.047) and accuracy with a lesser di stance from the target by -6.9 cm(p=0.039). Ball velocity in handball throws also signific antly increased by 1.2 km/h (p=0.013), while accuracy wasdeteriorated with a greater distance from the target by 3.4 cm (p=0.005). Larger effects with respect to ball speed werefound in players with a lower performance level in kick ing (1.7 km/h, p=0.028) and throwing (1.8 km/h, p=0.001)compared with higher level soccer and handball players (1.2 km/h, p=0.346 and 0.5 km/h, p=0.511, respectively). Inconclusion, the applications of kinesiot ape used in this study might have beneficial effects on performance in amateursoccer, but the gain in ball speed in handball is counterac ted by a significant deterioration of accuracy. Subgroupanalyses indicate that kinesiotape may yield larger effects on ball velocity in athletes with lower kicking and throwingskills.

Analysen zur Bedeutung sportlicher Aktivität im Setting Hochschule N2 - Im Beitrag wird eine „Systematische Übersicht und Meta-Analyse von Querschnittsstudien zum Zusammenhang zwischen körperlicher Aktivität und psychischer Gesundheit bei Studierenden“ vorgestellt. Auf Grundlage von 18 internationalen Studien wird die Frage beantwortet, inwieweit sich positive Assoziationen zwischen körperlicher Aktivität und psychischer Gesundheit auch bei Studierenden bestätigen lassen. Hierbei zeigt sich, dass psychische Beschwerden bei Studierenden vor allem in Form eines erhöhten Stresserlebens, von depressiven Symptomen und Angststörungen auftreten. Die Studienlage verweist zwar auf einen engen Zusammenhang von psychischer Gesundheit und körperlicher Aktivität, allerdings wurde dieser Zusammenhang bei Studierenden bislang noch nicht adäquat nachgewiesen. Lediglich für den Einfluss von körperlicher Aktivität auf Angststörungen wird ein moderater Zusammenhang ersichtlich. Da Studierende, die unter depressiven Beschwerden leiden, ihr Studium eher abbrechen, lässt sich die Schlussfolgerung ziehen, dass körperliche Aktivität eine relevante Größe für den Studienerfolg darstellen kann. Allerdings fehlen derzeit noch großangelegte empirische Studien, die sich explizit auf das deutsche Hochschulsystem beziehen.

Increasing physical activity and reducing sedentary time have been proved promising measures to promote mental health in the general population. However, to derive and implement effective measures to promote mental health among university students, further exploration of the associations between physical activity, sedentary time, and perceived stress in this specific setting is needed. Objective: This study aims to identify associations between physical activity, sedentary time, and perceived stress after controlling for sociodemographic and behavioral variables among university students in Germany. We hypothesize that perceived stress is inversely related to physical activity and positively associated with sedentary time. Furthermore, we hypothesize that combined associations of concurrently high physical activity and low sedentary time on perceived stress are stronger compared with either alone and that the association between physical activity and perceived stress depends on activity intensity. Methods: We conducted cross-sectional analyses from a large-scale internet-based student health survey (n=4189; response rate=10.0%). Physical activity, sedentary time, and engaging in moderate and vigorous activity intensities were assessed using the International Physical Activity Questionnaire Short Form with categorization into low, intermediate, and high levels. We measured perceived stress using the 10-item Perceived Stress Scale (range 0-40). Results: The results indicate that higher physical activity and lower sedentary time are associated with reduced levels of perceived stress. Following adjustment for gender, BMI, income, fruit and vegetable intake, alcohol consumption, and sleep quality, perceived stress scores were lower for students reporting high physical activity levels and low sedentary time compared with the least active and highly sedentary students (Perceived Stress Scale –2.2, 95% CI –2.9 to –1.5, P<.001 for physical activity and –1.1, CI 95% –1.7 to –0.5, P<.001 for sedentary time). Combined associations with perceived stress revealed that students concurrently reporting high total physical activity and low sedentary time reported the lowest perceived stress scores of all possible combinations following adjustment for confounders (Perceived Stress Scale –3.5, CI 95% –4.6 to –2.5, P<.001 compared with students reporting low physical activity levels and concurrently high sedentary time). Associations between vigorous physical activities and perceived stress were not stronger compared with moderate activity intensities. Conclusions: Self-reported physical activity and low sedentary time are favorably associated with perceived stress, while the intensity of physical activities seems to be of minor importance. These results help to effectively implement health-promoting measures on campus among university students through increasing physical activity and reducing sedentary time.

One way to mitigate adverse effects may be to increase head-neck stabilization and thus reduce the kinematic response after intentional headers. This study aimed to (a) assess associations between neck strength and head kinematics and (b) evaluate an exercise intervention designed to increase strength and attenuate head acceleration during intentional heading in youth soccer players. In 22 athletes, we used accelerometers to assess associations between neck strength and peak linear acceleration (PLA). We attached the accelerometers to the occiput and sternum, allowing us to differentiate between total, trunk, and head PLA. Longitudinally, we evaluated the effects of a 14-week twice-weekly resistance training in a subsample of 14 athletes compared with regular soccer training (N = 13). Results showed that female athletes had lower isolated neck strength (p ≤ 0.004), lower functional neck strength (p ≤ 0.017), and higher total PLA during purposeful headers compared with males (17.2 ± 3.5 g and 13.0 ± 2.3 g, respectively, at 9.6 m·s−1 ball velocity during impact; p = 0.003). The intervention group showed moderate to large strength gains (η = 0.16–0.42), resulting in lower PLA (total −2.4 g, trunk −0.8 g, and head −1.5 g) during headers. We conclude that a resistance training focusing on cervical and trunk musculature is practicable in youth soccer, elicits strength gains, and helps to mitigate PLA during purposeful heading. Results should encourage youth strength and conditioning professionals to incorporate neck exercises as a risk reduction strategy into their training routine.

It allows for the real-time measurement of objective criteria, such as flight time and landing position, without affecting the gymnast. The aim of this study was to investigate the temporal and spatial accuracy of a measurement tool via cross-validation. Temporal precision was additionally tested via high-speed video landing and takeoff, while a three-dimensional motion capturing system was incorporated for spatial precision. The Bland–Altman “limit of agreement approach” was used for the assessment of congruence between the measurement systems. The new measurement system presented an average spatial deviation of 3.2 cm and a temporal deviation between − 5.8 and + 6.4 ms for the landing and − 11.3 and + 11.3 ms for the takeoff. Given its temporal and spatial accuracy in determining flight time and landing position as identified through cross-validation, the novel HDTS system proved to be suitable for its use in trampoline competitions.

Design Eighty-eight patients with brain tumors (n = 59) and bone/soft tissue sarcomas (n = 29) were evaluated. Postural control was assessed examining the velocity of the center of pressure and single-leg stance time on a pressure distribution platform. Walk ratio, a measure of neuromotor control, was used to evaluate intervention effects on gait. Results Repeated measures analysis of variance showed improvements in postural control measures, indicated by a decrease in velocity of center of pressure of −0.4 cm/sec (F1,80 = 7.175, P = 0.009, ηp2 = 0.082) and increase in single-leg stance time (mean [median] = 1.1 [2.6] sec, respectively; F1,80 = 12.617, P = 0.001, ηp2 = 0.136). Walk ratio increased by 0.2 mm/steps per min (F1,82 = 3.766, P = 0.056, ηp2 = 0.044). Mean changes in dependent variables did not differ between both patient groups (P > 0.05). Conclusions The results indicate benefits of an inpatient rehabilitation program comprising standard physical therapy as well as aquatic and hippo therapy on postural control and gait after treatment of pediatric patients with cancer.

Furthermore, with growing prevalence, osteoarthritis is increasingly causing (in)direct costs. Guidelines recommend exercise therapy and education as primary treatment strategies. Available options for treatment based on physical activity promotion and lifestyle change are often insufficiently provided and used. In addition, the quality of current exercise programmes often does not meet the changing care needs of older people with comorbidities and exercise adherence is a challenge beyond personal physiotherapy. The main objective of this study is to investigate the short- and long-term (cost-)effectiveness of the SmArt-E programme in people with hip and/or knee osteoarthritis in terms of pain and physical functioning compared to usual care. Methods This study is designed as a multicentre randomized controlled trial with a target sample size of 330 patients. The intervention is based on the e-Exercise intervention from the Netherlands, consists of a training and education programme and is conducted as a blended care intervention over 12 months. We use an app to support independent training and the development of self-management skills. The primary and secondary hypotheses are that participants in the SmArt-E intervention will have less pain (numerical rating scale) and better physical functioning (Hip Disability and Osteoarthritis Outcome Score, Knee Injury and Osteoarthritis Outcome Score) compared to participants in the usual care group after 12 and 3 months. Other secondary outcomes are based on domains of the Osteoarthritis Research Society International (OARSI). The study will be accompanied by a process evaluation. Discussion After a positive evaluation, SmArt-E can be offered in usual care, flexibly addressing different care situations. The desired sustainability and the support of the participants’ behavioural change are initiated via the app through audio-visual contact with their physiotherapists. Furthermore, the app supports the repetition and consolidation of learned training and educational content. For people with osteoarthritis, the new form of care with proven effectiveness can lead to a reduction in underuse and misuse of care as well as contribute to a reduction in (in)direct costs.

However, there is a lack of studies examining a wide range of their lifestyle characteristics by sex and academic level of study. This cross-sectional survey of students enrolled in BSc, MSc, or PhD programs at one university in Germany (N = 3389) assessed physical activity (PA), sedentary behavior (SB), nutrition, sleep quality, and alcohol, tobacco, and other drug (ATOD) use by sex and academic level and was conducted with EvaSys version 8.0. Chi-squared tests compared categorical variables by sex, and binary logistic regression analyses adjusted for sex with Bonferroni adjustments evaluated differences across academic level. Although 91% of students achieved the aerobic PA guidelines, only 30% achieved the muscle strengthening exercises (MSE) guidelines, and 44% had high SB. Likewise, <10% met the fruit and vegetable consumption (FVC) recommendations, >40% of students experienced impaired sleep, and >30% had hazardous alcohol consumption. Less than 20% of the sample achieved the guideline/recommendation of all three PA, MSE and SB. Some behaviors exhibited significant sex and academic level differences. The identified at-risk groups included males (lower FVC), females (eating more during stress), and BSc students (poorer nutrition/sleep quality, more ATOD use). Given the above findings, multipronged strategies are needed with an overarching focus highlighting the health–academic achievement links. Behavioral interventions and environmental policies are required to raise awareness and promote student health.

By following up on previous work, the objective was to perform in-depth analyses evaluating external load (e.g., distance traveled, velocity, changes in direction, etc.) in beach handball players. In cross-sectional analyses, data of 69 players belonging to the German national or prospective team were analyzed during official tournaments using a local positioning system (10 Hz) and inertial measurement units (100 Hz). Statistical analyses comprised the comparison of the first and second set and the effects of age and sex (female adolescents vs. male adolescents vs. male adults) and playing position (goalkeepers, defenders, wings, specialists, and pivots) on external load measures. We found evidence for reduced external workload during the second set of the matches (p = 0.005, ηp2 = 0.09), as indicated by a significantly lower player load per minute and number of changes in direction. Age/sex (p < 0.001, ηp2 = 0.22) and playing position (p < 0.001, ηp2 = 0.29) also had significant effects on external load. The present data comprehensively describe and analyze important external load measures in a sample of high-performing beach handball players, providing valuable information to practitioners and coaches aiming at improving athletic performance in this new sport.

Die körperliche Aktivität und mentale Gesundheit Studierender stellen hierfür Ansatzpunkte dar. International zeigen sich eindeutige Zusammenhänge zwischen dem Bewegungsverhalten Studierender und der psychischen Gesundheit, jedoch liegen bisher nur wenige nationale Erhebungen vor, was die Übertragbarkeit auf die deutsche Hochschullandschaft einschränkt. Dieser Beitrag untersucht, wie in dieser Zielgruppe die aktuellen Bewegungsempfehlungen, bestehend aus den Kategorien ausdauerorientierte körperliche Aktivitäten, Sitzzeiten und muskelkräftigende Aktivitäten, mit verschiedenen Indikatoren mentaler Gesundheit zusammenhängen. Im Sommersemester 2019 nahmen 4.244 Studierende an einer hochschulweiten Umfrage teil. Neben dem Bewegungsverhalten wurden das Stresserleben erhoben und Screenings auf Kernelemente einer depressiven und angstbezogenen Störung sowie auf eine psychische Belastung durchgeführt. Positive Aspekte mentaler Gesundheit wurden über eine Skala zur Beurteilung studentischen Engagements erfasst. Als Assoziationsmaß wurden adjustierte Odds Ratios unter Berücksichtigung soziodemografischer und behavioraler Störvariablen berechnet. Sämtliche Kriterien der Bewegungsempfehlungen werden von 9,6% der Studierenden erreicht. 48% der Befragten weisen ein hohes Stresserleben auf und 29% gelten als psychisch belastet. Das Befolgen aller Kriterien der Bewegungsempfehlungen ist mit signifikant geringeren Chancen für psychische Belastungsindikatoren assoziiert, wobei der stärkste Zusammenhang für depressive Symptome gefunden wurde. Studentisches Engagement war nicht signifikant mit dem Erreichen der Bewegungsempfehlungen assoziiert. Die Ergebnisse bestätigen die hohe psychische Belastung Studierender und deuten das Optimierungspotenzial aus Sicht der Bewegungsförderung an. Hochschulen sollten die Studienbedingungen und das Gesundheitsverhalten der Studierenden systematisch und fortlaufend analysieren, um geeignete verhaltens- und verhältnisorientierte Maßnahmen wie bewegungsorientierte Lehre, Campusentwicklung und Ausbau des Hochschulsportangebots abzuleiten und zu evaluieren.

Mean Z-scores, areal BMD (g/cm2), calculated volumetric BMD (g/cm3) and bone mineral content (BMC, g) were determined. Results Lumbar spine mean Z-score was -0.14 (95% CI: -0.46 to 0.18), areal BMD was 1.016 g/cm2 (95% CI: 0.950 to 1.082) and volumetric BMD was 0.330 g/cm3 (95% CI: 0.314 to 0.347) which is comparable to healthy peers. For patients with a lower extremity tumor (n = 36), the difference between the affected and non-affected femoral neck was 12.1% (95% CI: -16.3 to -7.9) in areal BMD. The reduction of BMD was more pronounced in the calcaneus with a difference between the affected and contralateral side of 21.7% (95% CI: -29.3 to -14.0) for areal BMD. Furthermore, significant correlations for femoral and calcaneal DXA measurements were found with Spearman-rho coefficients ranging from ρ = 0.55 to ρ = 0.80. Conclusions The tumor disease located in the lower extremity in combination with offloading recommendations induced diminished BMD values, indicating local osteopenia conditions. However, the results revealed no significant decrements of lumbar spine BMD in pediatric sarcoma patients after completion of neoadjuvant chemotherapy. Nevertheless, it has to be taken into account that bone tumor patients may experience BMD decrements or secondary osteoporosis in later life. Furthermore, the peripheral assessment of BMD in the calcaneus via DXA is a feasible approach to quantify bone loss in the lower extremity in bone sarcoma patients and may serve as an alternative procedure, when the established assessment of femoral BMD is not practicable due to endoprosthetic replacements.

T1 - Walking ability during daily life in patients with osteoarthritis of the knee or the hip and lumbar spinal stenosis JF - BMC Musculoskeletal Disorders N2 - Background Degenerative musculoskeletal disorders are among the most frequent diseases occurring in adulthood, often impairing patients' functional mobility and physical activity. The aim of the present study was to investigate and compare the impact of three frequent degenerative musculoskeletal disorders -- knee osteoarthritis (knee OA), hip osteoarthritis (hip OA) and lumbar spinal stenosis (LSS) -- on patients' walking ability. Methods The study included 120 participants, with 30 in each patient group and 30 healthy control individuals. A uniaxial accelerometer, the StepWatch™ Activity Monitor (Orthocare Innovations, Seattle, Washington, USA), was used to determine the volume (number of gait cycles per day) and intensity (gait cycles per minute) of walking ability. Non-parametric testing was used for all statistical analyses. Results Both the volume and the intensity of walking ability were significantly lower among the patients in comparison with the healthy control individuals (p < 0.001). Patients with LSS spent 0.4 (IQR 2.8) min/day doing moderately intense walking (>50 gait cycles/min), which was significantly lower in comparison with patients with knee and hip OA at 2.5 (IQR 4.4) and 3.4 (IQR 16.1) min/day, respectively (p < 0.001). No correlations between demographic or anthropometric data and walking ability were found. No technical problems or measuring errors occurred with any of the measurements. Conclusions Patients with degenerative musculoskeletal disorders suffer limitations in their walking ability. Objective assessment of walking ability appeared to be an easy and feasible tool for measuring such limitations as it provides baseline data and objective information that are more precise than the patients' own subjective estimates. In everyday practice, objective activity assessment can provide feedback for clinicians regarding patients' performance during everyday life and the extent to which this confirms the results of clinical investigations. The method can also be used as a way of encouraging patients to develop a more active lifestyle.

The effectiveness of bracing mainly depends on patient compliance, which can be determined by means of temperature sensors. This methodological paper describes the feasibility of objectively determining compliance and daily physical activities before and during conservative scoliosis treatment, being a relevant indicator for quality of life in children and adolescents. One patient with low compliance (61.4±24.9%) reduced her activity level during bracing by 50.1%, whereas another patient with a satisfactory compliance (85.7±19.5%) increased her daily activity level by 33.7% during conservative treatment.

Derzeit existiert keine Methode, die präzise alle Formen der Alltagsaktivitäten erfassen kann. Diese Übersichtsarbeit beschreibt und vergleicht auf Basis einer umfassenden Literaturrecherche moderne Messverfahren zur Erfassung körperlicher Aktivitäten im Alltag, bei der die Darstellung objektiver Verfahren einen Schwerpunkt bildet. Subjektive Erhebungsmethoden wie Fragebögen und objektive Aktivitätsmonitore, zu denen Schrittzähler und Akzelerometer zählen, sowie kombinierte Verfahren von Akzelerometrie und Herzfrequenz, sind derzeit die gängigsten Methoden, Alltagsaktivitäten zu erfassen. Daneben existieren weitere Möglichkeiten wie Doubly Labeled Water, Kalorimetrie oder direkte Beobachtungen der Testperson, die als Goldstandard des Activity Assessments angesehen und zur Validierung oben genannter Verfahren genutzt werden können. Obwohl diese Methoden das größte Potential bei der Erfassung körperlicher Aktivitäten hinsichtlich der Messpräzision haben, muss bei der Auswahl der Erhebungsmethode angesichts der Vielzahl an Möglichkeiten auch ihre Anwendbarkeit berücksichtigt werden.

One immense restriction consists in a reduced level of activity due to different factors. Physical activity affects various aspects of development and can be regarded as an essential part of a child's life. In the present study physical activity in patients undergoing cancer therapy was quantified in order to determine the extent of the restriction and to provide baseline information for the assessment of possible interventions. Procedure Physical activity in 80 patients and 45 healthy children matched for age and gender was measured using the StepWatch 3™ Activity Monitor (SAM, OrthoCare Innovations). Results Pediatric cancer patients, at 2,787 gait cycles (gcs) per day, were significantly less active than their healthy counterparts (8,096 gcs). Patients were significantly more active at home than during inpatient stays (3,185 gcs compared to 1,830 gcs), and patients with bone tumors were less active than those with leukemia regarding both, the amount (1,849 gcs vs. 2,992 gcs) and the intensity of activity. Conclusion The present study quantified an often observed but so far hardly assessable problem. Activity in cancer patients is considerably reduced and patients with bone tumors are at increased risk from the detrimental effects of prolonged inactivity. Both our findings and the accepted fact that activity is an essential element of child development confirm the need for interventions tailored to a patient's needs and abilities during the course of treatment.

Employing an online cross-sectional study, the short-form of the Big Five Inventory-2 assessed five domains of personality traits (Extraversion, Negative Emotionality, Agreeableness, conscientiousness, and Open-Mindedness). PA, including sitting time, was assessed using the International Physical Activity Questionnaire (short-form). SRF and muscle-strengthening activities (MSA) were assessed with one item each. Multiple linear and logistic regression analyses examined associations of individual personality trait domains and all domains combined with SFR, PA variables, and adherence to PA guidelines, controlling for sociodemographic, behavioral, and (mental) health covariates. Most reliably, Extraversion and Conscientiousness revealed positive associations with PA variables, while Negative Emotionality yielded inverse relationships with PA variables. For instance, each unit increase in Extraversion corresponded to an additional 17 min of weekly MSA. On the contrary, daily sitting time was unrelated to personality. Of note, high Open-Mindedness was associated with lower odds for adhering to current PA guidelines. The findings have implications for developing targeted interventions that promote a physically active lifestyle and support students’ well-being and academic success.

Entwicklung des Aktivitätsniveaus und Einfluss auf die Knochendichte JF - Pädiatrische Praxis N2 - Tumorerkrankungen im Kindes- und Jugendalter haben während der Akuttherapie und darüber hinaus einen signifikanten Einfluss auf das Aktivitätsniveau und den Knochenstoffwechsel. Dieser Beitrag untersucht, inwiefern bewegungstherapeutische Interventionen das Aktivitätsniveau und damit auch die Entwicklung der Knochendichte während der Akuttherapie von Patienten mit Knochentumoren der unteren Extremität beeinflussen können. 21 Kinder und Jugendliche im Alter von 13,6 Jahren konnten in die Untersuchung aufgenommen werden und wurden einer Interventions- (IG, n=10) oder einer Kontrollgruppe (KG, n=11) zugeordnet. Sämtliche Patienten erhielten die standardisierte physiotherapeutische Behandlung. Der IG wurde zusätzlich ein Sportprogramm angeboten, das an jedem zweiten Tag während der Akuttherapie absolviert werden sollte. Die Knochendichte der Lendenwirbelsäule und des nicht betroffenen Schenkelhalses wurde mittels Dual-Röntgen-Absorptiometrie (DXA) während der Lokaltherapie, sowie nach sechs und nach zwölf Monaten erfasst. Die Alltagsaktivitäten wurden zeitgleich nach sechs und zwölf Monaten im heimischen Umfeld objektiv mit einem Beschleunigungsaufnehmer über einen Zeitraum von sieben Tage erhoben. In beiden Patientengruppen wurde während der Akuttherapie eine deutliche Reduktion der Knochendichte beobachtet. Im Gruppenvergleich zeigten sich in der Entwicklung der Knochendichte zwischen den Messzeitpunkten kleine bis große Effekte zugunsten der bewegungstherapeutischen Intervention. Zudem weist die Interventionsgruppe im Vergleich zur Kontrollgruppe durchweg signifikant höhere Alltagsaktivitäten (durchschnittliche Schrittzahl pro Tag und Phasen hoher körperlicher Aktivität) auf. Die Ergebnisse belegen die Durchführbarkeit und den Nutzen eines therapiebegleitenden Sportprogramms für Kinder und Jugendliche während der Akutphase der Behandlung einer Knochentumorerkrankung der unteren Extremität.

Empfehlungen zur Methodik JF - Sportwissenschaft N2 - Die Akzelerometrie ist als objektives Messverfahren zur Erfassung körperlicher Aktivität im Feld mit guten psychometrischen Eigenschaften und Anwendbarkeit auch bei großen Stichproben international etabliert. Akzelerometer zeichnen Intensität und Dauer ein- oder mehraxialer Beschleunigungen auf. Umfänge leichter, moderater und intensiver körperlicher Aktivitäten sowie Zeiten der Inaktivität können mit Hilfe von Cut-point-Modellen abgegrenzt, sowie der Energieumsatz auf Basis von Regressionsmodellen geschätzt werden. Allerdings bleibt die Vergleichbarkeit von Ergebnissen aufgrund unterschiedlicher Modelle, Trageprotokolle, Kalibrationsverfahren und Ergebnisdarstellungen schwierig. Die vorliegenden Empfehlungen, Perspektiven und Limitationen der Messmethodik wurden unter Beteiligung aller Autoren erarbeitet und im Konsens verabschiedet. Aktuell kann kein Gerätemodell pauschal empfohlen werden, da die Wahl des Gerätes von Forschungsfrage, -design und Zielgruppe abhängt. Für ein möglichst objektives Abbild des habituellen Bewegungsverhaltens werden ein Messzeitraum von mindestens 7 Tagen inklusive einem Wochenendtag und eine Tragedauer von mindestens 10 h pro Tag bei Erwachsenen empfohlen. Zur Vermeidung von Verzerrungen aufgrund aggregierter Daten sollten möglichst kurze Epochenlängen gewählt bzw. nicht vorprozessierte Rohwerte gespeichert werden. Für Erwachsene gilt das Cut-point-Modell von Freedson et al. (1998) zur Bestimmung unterschiedlicher Aktivitätskategorien als etabliert. Methodische Limitationen bestehen insbesondere bei der Erfassung von Aktivitäten mit geringer oder sehr hoher Beschleunigung des observierten Körpersegments, wie Fahrradfahren oder Krafttraining, und bei der Berechnung des Energieumsatzes auf Basis linearer Regressionsmodelle.

Aim of this study was to compare the clinical and functional outcomes of Chopart, Lisfranc fractures and multiple metatarsal shaft fractures. Design Retrospective case series. Setting Level one trauma center. Intervention Open or closed reduction and internal fixation with screws, K-wires, plates, external fixation or combination of different technics. Main outcome measurements The American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot Score and the Maryland Foot Score were used to assess pain and functional outcome. 3D gait analysis, pedobarographic analysis and radiologic examinations were performed. The activity level was measured by a step counting accelerometer. All results were compared to an age-matched healthy control group. Results 24 patients with a median age of 44 years (16–72) were included: 12 patients with multiple metatarsal shaft fractures, 6 patients with Chopart and 6 patients with Lisfranc fractures. The median follow-up was 2.6 years. The pedobarographic analysis reports reduced contact time of the total foot (p = 0.08), the forefoot (p = 0.008) and the hallux (p = 0.015) for the injured foot. A median score of 64 for the SF-36, 64 for the AOFAS Midfoot Score and 73 for the Maryland Foot Score indicated a poor restoration of foot function. Multiple metatarsal shaft fractures presented a significantly lower walking speed (p = 0.03) and cadence (p = 0.04). Conclusion The worst results were reported for multiple metatarsal shaft fractures on outcome scores, pedobarography, gait analysis and activity. Metatarsal serial fractures should not be underestimated as well as Chopart and Lisfranc fractures.

DXA of the lumbar spine, the non-affected femur and both calcanei was performed after completion of neoadjuvant chemotherapy (baseline), as well as 6 and 12 months after baseline. Bone mineral content (BMC), bone mineral density (BMD) and height-corrected lumbar spine Z-scores were determined. Group changes after 6 and 12 months were compared by covariance analyses. Additionally, daily physical activities (PA) were assessed by means of accelerometry. After adjusting for initial age, height and weight, mean reductions in lumbar spine and femoral BMC were lower in the exercise group (not significant). Effect sizes during the observational period for lumbar spine and femur BMC were generally small (partial η²=0.03). The exercise group demonstrated substantially higher PA levels in terms of gait cycles per day, per hour and moderate PA (activities above 40 gait cycles per minute). Additional exercises for bone tumor patients are feasible during hospitalization. Though the intervention did not influence BMC, it appeared beneficial regarding PA promotion with respect to volume and intensity.

However, pediatric patients experience great limitations to being physically active, and appropriate interventions are desired. Procedure The present study aimed at investigating the effects of individualized exercise interventions during inpatient stays on pediatric patients with a malignant bone tumor. The parameter of interest was physical activity (PA). Patients’ PA during home stays was assessed 6 weeks as well as 3, 6, 12, and 18 months post-surgery. Patients were distinguished into an intervention group and a control group. All patients received endoprosthetic replacement of the affected bone in the same institution. Results A constant increase in all PA parameters was observed during follow-up. Exercise interventions were possible and appeared worthwhile. The intervention group showed better PA results at all measurements; however, no significant differences between groups were found. Furthermore, differences decreased especially after the cessation of the intervention. General problems in reaching appropriate power and compliance were observed. Conclusions Individualized exercise interventions in pediatric bone tumor patients are possible and appear to be beneficial. Such interventions should be implemented in adjuvant care; however, future research is needed to understand more about the effects of different interventions.

Compliance among adolescents is frequently inadequate due to the discomfort of wearing a brace, cosmetic issues, and fear on the part of patients and parents that bracing may reduce everyday physical activities. The aim of this prospective, controlled study was to objectify the impact of spinal bracing on daily step activity in patients receiving conservative treatment for adolescent idiopathic scoliosis (AIS) or adolescent kyphosis (AK). Forty-eight consecutive patients (mean age 13.4 ± 2.3 years), consisting of 38 AIS patients (33 girls, 5 boys) and 10 AK patients (6 girls, 4 boys) were included. Once the decision to carry out bracing had been taken and while the patients were waiting for the individual brace to be built, step activity was assessed without braces by means of step activity monitoring (SAM) for seven consecutive days. After 8 weeks of brace wearing, step activity was assessed during regular brace treatment, again for seven consecutive days. In addition, brace-wearing times were simultaneously recorded using temperature probes implanted in the braces to measure compliance. Before and during brace treatment, patients completed the Scoliosis Research Society (SRS-22) questionnaire. The SAM was worn for an average of 12.7 ± 1.5 h/day during the first measurement and 12.3 ± 1.9 h on average during the second measurement. The mean gait cycles (GCs) per day and per hour before treatment were 5,036 ± 1,465 and 395 ± 105, respectively. No significant reduction in step activity was found at the follow-up measurement during bracing, at 4,880 ± 1,529 GCs/day and 403 ± 144 GCs/h. Taking the 23-h recommended time for brace wearing as a basis (100%), patients wore the brace for 72.7 ± 27.6% of the prescribed time, indicating an acceptable level of compliance. Girls showed a higher compliance level (75.6 ± 25.6%) in comparison with boys (56.7 ± 31.9%), although the difference was not significant (P = 0.093). The SRS-22 total score showed no differences between the two measurements (2.57 ± 0.23 vs. 2.56 ± 0.28). Implementing a simultaneous and objective method of assessing step activity and brace-wearing times in everyday life proved to be feasible, and it expands the information available regarding the impact of bracing on patients’ quality of life. The results clearly show that brace treatment does not negatively interfere with daily step activity in AIS and AK patients. This is an important finding that should help reduce patients’ and parents’ worries concerning bracing.

JF - Supportive Care in Cancer N2 - Purpose The diagnosis of a malignant bone tumor in the lower limb is a risk factor for physical disability, limiting physical performance. Walking ability especially, which is essential for most activities of daily living, is limited in those patients. In the present study, the extent of limitations during the course of treatment was investigated to determine when the assessment of functional parameters is meaningful in those patients. Methods In the present study, activity levels were determined in 20 patients with a malignant bone tumor in the lower limb who received endoprosthetic replacement of the affected bone and in 20 healthy individuals. A uniaxial accelerometer was used to investigate patients at five different time points after surgery. Results Patients performed significantly less amounts and intensities of activity than control individuals at all measurements. Significant increases in the volume of activity were observed after cessation of treatment. However, the intensity of activity only showed minor increases. Patients experiencing complications of surgery revealed greater restriction than those without even 18 months after surgery. Conclusions After cessation of treatment for their disease, patients recovered markedly and showed great improvements in physical activity. However, some limitations appeared to persist. Comparisons with patients with longer follow-up revealed that meaningful functional assessment does not make sense within the first 12 months after surgery. More research is needed to show if longer follow-up periods reveal further improvements. Based on such information, it should be more promising to develop individually tailored activity recommendations and intervention programs.
