Individuals with physical disabilities may benefit from cycling interventions, which could address impairments while potentially minimizing stress on joints. Improvements in impairments may then have an impact on mobility, activity, and participation. Cycling studies with adults and children who are healthy have shown that many factors can influence the biomechanics of cycling. These factors include seat height, crank arm length, foot position, cadence, and workload. Knowledge of these factors is important for rehabilitation professionals who prescribe cycling as an intervention for individuals with disabilities, because changing these factors can potentially influence the therapeutic outcomes. In addition, further research is needed to fully understand the effect of these factors on individuals with disabilities.
