| | MUKHERJEE and SAMANTA: Ambulatory performance of hand-rim and arm-crank propulsion (Site not responding. Last check: 2007-10-23) |
 | | It can be inferred from the result that the AC propulsion system could be used for long distance rides with a higher speed required for outdoor ambulation and that the HR propulsion system is suitable only for indoor use, because of its excellent maneuverability where short duration low velocity ambulation is required. |
 | | The upper limb movement in the arm-crank propulsion system is simpler than the hand-rim system because additional coordinated and discontinuous movements of arm and substantial gripping force required in MWC propulsion. |
 | | The gross mechanical efficiency of hand rim is lower than the arm-crank system (12,25,26); this may be due to ineffective application of the propulsive force that is less than optimal direction of the applied force, and the effectiveness is decreased with increase in speed (27). |
