Sliding and pressure evaluation on conventional and V-shaped seats of reclining wheelchairs for stroke patients with flaccid hemiplegia: a crossover trial.

For able-bodied subjects, the SPP was less in the wheelchairs with V-shaped seats than in the conventional wheelchairs; this difference was apparent at the initial measurement and after cycle 4, and there was a marginal difference after cycle one.
