An Electromyographic Study Of The Quadriceps And Hamstrings Recruitment During Two Closed Kinetic Chain Activities, Linda K. Hanson, Shauna T. Salz, Suzanne L. Steffes

Physical Therapy Scholarly Projects

Knee pain and injury are a commonly seen diagnosis in physical therapy practice. Closed kinetic chain activities are frequently used to treat these diagnoses, because of their safety and functional properties. However isolation of specific muscles is difficult with closed kinetic chain exercises. The researchers chose to further study closed kinetic chain exercises in order to compare traditional closed kinetic chain exercises with a recently developed closed kinetic chain device. The purpose of this study is to assess EMG activity of the quadriceps and hamstrings during two different closed kinetic chain activities of the knee, one a traditional method and …
