OBJECTIVE MEASUREMENTS OF DAILY ACTIVITY PATTERNS OF ‘SPORTIVE’ KNEE OSTEOARTHRITIS (KOA) PATIENTS

Knee osteoarthritis patients suffer from a painful disease but it has yet to be determined how their activities in daily life may be affected or whether they might still be able to engage in regular sports. To that effect, we measured and analyzed the physical activity patterns in a group of 15 self-reported sports-active KOA patients with accelerometric activity monitors

International Foot and Ankle Biomechanics Community (i-FAB): past, present and beyond

The International Foot and Ankle Biomechanics Community (i-FAB) is an international collaborative activity which will have an important impact on the foot and ankle biomechanics community. It was launched on July 2nd 2007 at the foot and ankle session of the International Society of Biomechanics (ISB) meeting in Taipei, Taiwan. i-FAB is driven by the desire to improve our understanding of foot and ankle biomechanics as it applies to health, disease, and the design,development and evaluation of foot and ankle surgery, and interventions such as footwear, insoles and surfaces

International scientific consensus on medical plantar pressure measurement devices: technical requirements and performance

Background. Since 2006, the Italian National Institute of Health (ISS) has been conducting independent scientific activities to standardize the technical assessment of plantar pressure measurement devices (PMDs). Material and methods. On the basis of the ISS results, in 2010 the Pedobarographic Group of the International Foot and Ankle Biomechanics community (i-FAB-PG) promoted a consensus activity about the main technical requirements for the appropriate use of PMDs. The activity relied on a moodle- based on-line forum, documents exchange, discussions, reviews, meetings and a final sur - vey. Results. The participation of clinical and technical researchers, users, and manufactur - ers, contributed to the delivery of the hereby reported recommendations which specifically regard Medical PMDs in the form of platforms. Conclusions. The i-FAB-PG community reached overall agreement on the recommendations, with a few minor objections which are reported and commented in the document. Relevance. The present document, the highest result achievable within a small scientific community, will hopefully represent the starting point of the wider process of establishing official international guidelines or standards, within scientific communities and standardization organizations

Rotationplasty in the Elderly

Purpose. Rotationplasty has proven its efficacy in the treatment of malignant bone tumors of the lower extremity in predominantly young patients. To our knowledge this procedure has not been reported in patients over 60 years before. Materials and Methods. 3 patients over 60 years with an A1-rotationplasty because of a sarcoma were included in this study. Complications and functional results were recorded. In one patient an electromyography was done. Results. Despite electromyography showing good adaptation of the muscles to the altered function, the functional results of these three patients were limited. two out of three patients needed a cane for walking distances over 200 meters. No secondary amputation was necessary. Discussion. Our study demonstrates that rotationplasty is an alternative to an above-knee amputation in older patients but with poorer functional results in comparison to younger patients. However, limb-salvage surgery should be preferred whenever possible

RECOVERY OF DAILY ACTIVITY PATTERNS IN PATIENTS AFTER ACL RECONSTRUCTION

Injuries of the anterior cruciate ligament are one of the most often occurring injuries during sports activities. For young active patients, surgical treatment with repair, augmentation or replacement of the involved structure(s) is advised. The present study compared the outcome after Ligamys repair and Semitendinosus reconstruction during the first six postoperative weeks with objective measurements of the activity/inactivity behavior in daily life

Changes in physical activity and health-related quality of life during the first year after total knee arthroplasty,”

Objective. Despite its impact on the overall outcome and health-related quality of life (HRQOL) after knee surgery, physical activity has not been investigated directly using accelerometry or step monitoring during the first year after total knee arthroplasty (TKA) due to osteoarthritis (OA). Therefore, the present study aimed to evaluate the development of physical activity over 12 months after surgery and its relationship to clinical outcome and HRQOL. Methods. Fifty-three patients scheduled for primary TKA due to OA were measured with the DynaPort ADL monitor and a step activity monitor preoperatively and at 2, 6, and 12 months of followup. Clinical outcome and HRQOL were investigated using the American Knee Society Score (KSS) and Short Form 36 (SF-36) health survey. Results. Physical activity increased significantly within 12 months of followup (from mean ؎ SD 4,993 ؎ 2,170 gait cycles preoperatively to 5,932 ؎ 2,111 gait cycles; P ‫؍‬ 0.003). Clinical outcome and HRQOL improved from baseline (mean ؎ SD KSS 88.9 ؎ 21.4, mean ؎ SD SF-36 43.1 ؎ 18.4) to 12 months of followup (mean ؎ SD KSS 188.6 ؎ 10.9; P ‫؍‬ 0.001 and mean ؎ SD SF-36 82.5 ؎ 15.9; P ‫؍‬ 0.001). Physical activity parameters did not correlate with clinical outcome. Conclusion. TKA offers profound improvements of physical activity for the majority of patients. Despite these improvements and the excellent clinical outcome, most patients do not reach the level of physical activity reported for healthy subjects. The activity level after treatment seems to be influenced by physical activity behavior prior to surgery rather than by the treatment itself

Comparisons of foot anthropometry and plantar arch indices between German and Brazilian children

Abstract\ud \ud Background\ud Nowadays, trades and research have become closely related between different countries and anthropometric data are important for the development in global markets. The appropriate use of anthropometry may improve wellbeing, health, comfort and safety especially for footwear design. For children a proper fit of footwear is very important, not constraining foot growth and allowing a normal development. The aim of this study was to compare the anthropometric characteristics of German and Brazilian children’s feet from 3 to 10 years of age.\ud \ud \ud Methods\ud We compared five indirect measures of two databases of children's feet. Forefoot, midfoot and rearfoot widths were measured in static footprints and the Chippaux-Smirak and Staheli indices of the longitudinal arch were calculated.\ud \ud \ud Results\ud Brazilian children showed a significantly narrower forefoot from 5 to 10 years, wider rearfoot from 3 to 4 years, wider midfoot for 4 year-olds and narrower midfoot for 10 year-old children. Nevertheless, the Chippaux-Smirak and Staheli indices showed no group differences. The only exception was for 4 year-old Brazilian children who showed a higher Chippaux-Smirak index compared to German children (48.4 ± 17.7%; 42.1 ± 13.8%).\ud \ud \ud Conclusions\ud Our study revealed anthropometric differences in absolute forefoot and rearfoot widths of German and Brazilian children, but a similar longitudinal arch development. At 4 years of age, Brazilian children present a foot anthropometry similar to the 3 year-olds and develop the plantar longitudinal arch from 4 to 5 years more rapidly when compared to German children.FAPESPDeutsche Forschungsgemeinschaf (DFG

Walking ability during daily life in patients with osteoarthritis of the knee or the hip and lumbar spinal stenosis: a cross sectional study

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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.</p> <p>Conclusions</p> <p>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.</p
