  abstract  = {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.},

Die pr{\"a}zisesten Ergebnisse unter kontrollierten Bedingungen wurden mit einem piezoelektrischen Pedometer erzielt. Die absoluten Abweichungen (Median) lagen f{\"u}r diesen Schrittz{\"a}hler bei den Kindern zwischen 0,2 und 1,0\%, bei den Erwachsenen zwischen 0,2 und 1,4\%. Die absoluten Abweichungen f{\"u}r den Akzelerometer lagen zwischen 0,8 und 3,1\% f{\"u}r die Schulkinder sowie zwischen 0,6 und 3,2\% f{\"u}r die Erwachsenen. Die Messpr{\"a}zision stieg unter kontrollierten Bedingungen mit zunehmender Bewegungsgeschwindigkeit an. Besonders bei den Schulkindern wiesen einige Schrittz{\"a}hler mit Pendelarm-Mechanismus hohe absolute Abweichungen von {\"u}ber 50\% auf. Die Unterschiede unter Alltagsbedingungen verdeutlichen, dass Schrittzahlangaben diverser Monitore nicht direkt miteinander verglichen werden k{\"o}nnen. In jedem Fall sollten Schrittz{\"a}hler vor ihrem Einsatz in wissenschaftlichen Untersuchungen auf G{\"u}tekriterien wie Validit{\"a}t und Reliabilit{\"a}t gestestet werden.},

  abstract  = {Bracing is an established method of conservative treatment for adolescent idiopathic scoliosis and kyphosis. 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.},
