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.}, language = {en} } @article{MuellerWinterRosenbaumetal.2010, author = {M{\"u}ller, Carsten and Winter, Corinna and Rosenbaum, Dieter and Boos, Joachim and Gosheger, Georg and Hardes, Jendrik and Vieth, Volker}, title = {Early decrements in bone density after completion of neoadjuvant chemotherapy in pediatric bone sarcoma patients}, series = {BMC Musculoskeletal Disorders}, volume = {11}, journal = {BMC Musculoskeletal Disorders}, number = {287}, doi = {10.25974/fhms-16866}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-168661}, pages = {1 -- 8}, year = {2010}, abstract = {Background Bone mineral density (BMD) accrual during childhood and adolescence is important for attaining peak bone mass. BMD decrements have been reported in survivors of childhood bone sarcomas. However, little is known about the onset and development of bone loss during cancer treatment. The objective of this cross-sectional study was to evaluate BMD in newly diagnosed Ewing's and osteosarcoma patients by means of dual-energy x-ray absorptiometry (DXA) after completion of neoadjuvant chemotherapy. Methods DXA measurements of the lumbar spine (L2-4), both femora and calcanei were performed perioperatively in 46 children and adolescents (mean age: 14.3 years, range: 8.6-21.5 years). 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.}, language = {en} } @inproceedings{JuestelKatelnikovasWinkler2010, author = {J{\"u}stel, T. and Katelnikovas, A. and Winkler, H.}, title = {Orange to Red Emitting (Ca,Sr,Ba)SiN2:Eu2+ Luminescent Materials for Phosphor Converted LEDs}, series = {ICLL-1, Odessa, Ukraine}, booktitle = {ICLL-1, Odessa, Ukraine}, year = {2010}, language = {en} } @inproceedings{KucGreuelJuestel2010, author = {Kuc, J. and Greuel, G. and J{\"u}stel, T.}, title = {Coating of UV-C Phosphor YPO4:Bi3+ with MgO, Al2O3, and MgAl2O4}, series = {Excited Stated of Transition Elements, Piechowice, Poland}, booktitle = {Excited Stated of Transition Elements, Piechowice, Poland}, year = {2010}, language = {en} }
