Manual Wheelchair Propulsion Training

摘要: Manual wheelchair users are at high risk of developing upper limb pain and injury. While much has been published identifying the prevalence pain, very little on its treatment prevention. Consequently, a propulsion training system was developed based biomechanical, ergonomic, motor learning theory principles. Three groups were compared: control group (CG) that received no training, an instruction only (IO) reviewed multi media instructional presentation (MMP), feedback (FB) MMP additional real time (RTF). The purpose this study to 1) Develop propulsion-training programs minimized injurious biomechanics; 2) Test if can cause lasting changes; 3) Investigate resultant forces moments shoulder be reduced 4) To determine one (MMP) superior other (RTF) in achieving these goals. First, RTF systems' design completed tested pilot subject (chapter 2). Next systems over ground dynamometer where modeled (N=27). Results showed baseline measures extremely low did not increase significantly. In addition, effects influenced by surface type or speed condition (presence absence target speed). chapter 2, FB who displayed larger increases contact angle(CA)(angle along arc hand rim) greater decreases rate rise peak force (rorFr) than IO alone.5While both decreased stroke frequency (SF), reduction group. Furthermore, short term (maxFr) however their long values significantly Finally, CG maxFr rim (p<.05), increase.
