Optimisation of a bicycle chainring to aid in rehabilitation of athletes suffering from patellofemoral pain syndrome (PFPS)

摘要

Patellofemoral Pain Syndrome (PFPS) is a frequently occurring problem whose causation is multifactorial. Supposed triggers include mal-tracking patella due to an imbalance in the muscles of the quadriceps. There are numerous treatments for the pain; for example, strengthening of the quadriceps shows good clinical results. In this study, the geometry of a bicycle chainring has been optimised to increase the recruitment of Vastus Medialis Oblique (VMO). The intention is to strengthen VMO as part of a rehabilitation program to relieve the pain associated with PFPS.
