Stylized illustration of stroke pattern classification during wheelchair propulsion. The hand contacts the rim at the top, is constrained to follow the hand rim during the push but the user is free to choose how to follow through between pushes. In the arcing pattern, the user’s hand travels back along the hand rim between pushes (adapted from Richter et al. ).
