Abstract

Purpose: This case study is aimed at determining if Neuromuscular Electrical Stimulation (NMES) and physical therapy (PT) are better for increasing lower extremity strength and function in patients following total knee arthroplasty (TKA) compared to physical therapy alone. Background: TKA surgery is increasing yearly and is expected to greatly increase by 2030. After a TKA, patients may suffer from decreased strength and physical function even after physical therapy has been performed. The use of NMES and exercise for quadriceps activation post-ACL reconstruction has been found to be highly effective. Its use has been suggested to be just as effective after a TKA at improving a patients quadriceps strength and increase overall function. Case Description: Patient is a 75 year old man who underwent a left TKA in October of 2014. The physical therapy for this patient revolved around performing knee range of motion (ROM) exercise, non-weight bearing exercise, gait training, and weight bearing exercises. Outcomes: A review of current literature revealed that the use of NMES and physical therapy after TKA may help to attenuate the loss of quadriceps strength and activation after surgery and return lower extremity strength and function to a higher level than exercise alone. Discussion: A 2010 Cochrane review of this topic determined that there were not enough high quality research articles to make a recommendation on the use of NMES after TKA. Subsequently, four randomized clinical trials (RCTs) have been published. Within these four RCTs there was a wide variety in research methodology, specifically, the parameters used during the NMES treatment. Despite this inconsistency, the studies have shown that NMES may be an effective treatment after TKA for increasing quadriceps strength and returning lower extremity function.
