简要总结
Participants diagnosed with tibial femoral knee osteoarthritis will be assigned to one of three treatment groups including: active transcutaneous electrical nerve stimulation (TENS), placebo TENS, and a control group. Assignment of conditions will be concealed. All participants in each of the three groups will receive physical therapy for all 4 weeks of the intervention. Main outcome measures will include quadriceps central activation ratio, quadriceps torque production, WOMAC scores, visual analog pain scores during gait as well as knee joint kinetics and kinematics during gait. The purpose of this study is to to determine if the continuous use of TENS therapy for activities of daily living and rehabilitation will positively impact all outcome measures.
