Mechanical energy and power flow analysis of wheelchair use with different camber settings.

摘要: It has been suggested that minimisation of energy cost is one the primary determinants wheelchair designs. Wheel camber important parameter related to design and its angle may affect usability during manual propulsion. However, there little available literature addressing effect wheel on mechanical or power flow involved in Twelve normal subjects (mean age, 22.3 years; SD, 1.6 years) participated this study. A video-tracking system an instrumented were used collect 3D kinematic kinetic data. 0° 15° was chosen examine difference between upper extremity The work calculated from discrepancy had significantly greater values with increased camber. arm a larger active muscle compared forea...
