Introduction. Wheelchair configuration is an important factor influencing the ergonomics of the user–device interface and, from a biomechanical point of view, small changes in chair setup may have a positive influence on ...

The wheelchair handrim is a key factor in the wheelchair ergonomics and has been shown to affect both user's comfort and propulsion efficiency. Since the handrim is used for both pushing and braking, friction is an important ...

This study is aimed at investigating how contact forces are distributed over the hand's surface during manual wheelchair propulsion with two different designs of handrim. Twenty able-bodied subjects performed a ...

This study investigated the influence of mass distribution on the handrim forces during manual propulsion in four different mobility tasks: Straightforward motion at self-selected speed; straightforward sprint; zero radius ...

This preliminary study investigated the effect of the implementation of a servo-controlled power assisted mechanism in a manual wheelchair on the demands of the upper limb muscles and the subjects' perception about the ...
