Comparative evaluation of ambulation patterns and isokinetic muscle strength for the application of rehabilitation exercise in patients with patellofemoral pain syndrome.
[Purpose] The aim of this study was to evaluate the differences in the ambulation patterns and knee joint performance between people with and without patellofemoral pain. The present study also aimed to utilize these results as a basis for the development of pain-alleviating and performance-improving treatment programs. [Subjects and Methods] Subjects consisted of 32 adult females diagnosed with patellofemoral pain syndrome and 25 adult females without patellofemoral pain (controls). Contact ratio patterns during ambulation and isokinetic muscle strength around the knee joint were measured in both groups and then compared. [Results] Ambulation patterns, specifically the contact ratios of the left forefoot and right forefoot, differed significantly between patients with patellofemoral pain syndrome and controls. An isokinetic muscle strength test demonstrated that left and right knee extensor and flexor torques also significantly differed between these two groups. [Conclusion] Basic analysis based on ambulation patterns and muscle strength can be used to indicate functional recovery from patellofemoral pain syndrome and provide insight into improving the rehabilitation of patients.
