    Stroke pattern classifications during wheelchair propulsion (stylized illustrations). The hand is constrained to follow the handrim 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 handrim between pushes. Abbreviations: ARC, arcing; DLOP, double looping; SC, semi-circular; SLOP, single-looping.

    The freely chosen stroke patterns were fairly balanced for level propulsion, but the arcing pattern became the most popular for pushing uphill.
