Graston Technique versus Muscle Energy Technique on Hamstring Flexibility in Knee Osteoarthritis Patients - Trial PACTR201707002386207

Timeline & Enrollment

Summary

Osteoarthritis (OA) is one of the most prevalent articular disorders affecting humankind and a major cause of disability and socioeconomic burden. It can be defined as a chronic degenerative disorder that is characterized by multifactorial etiology, including acute and/or chronic insults from normal wear and tear, age, obesity, and joint injury. Functional disability is a typical characteristic in people with knee osteoarthritis. Over the years, numerous factors have been proposed as possible explanations for the level of functional disability in people with knee OA. Among these factors is reduced knee joint range of motion. One of the factors that compromise knee joint range of motion is hamstring tightness. Several studies have indicated that flexibility of the hamstrings is improved by stretching. Indeed, many stretching techniques are used in clinical practice, including ballistic stretching, static stretching, and muscle energy technique. Recently, Graston instrumented soft tissue mobilization has been reported to be effective in promoting the extensibility of the shortened hamstring. The purpose of this study is to compare the effect of Graston Technique and Muscle Energy Technique on hamstring flexibility in in knee osteoarthritis patients.Subjects with moderate unilateral OA of the knee on the dominant side (Kellgren & Lawrence grade 3' moderate') from both sexes will be selected by simple random method aged between 38 and 50 years, their BMI below 30 kg/m2. They will be randomly divided into 3 equal groups I, II and III. We will assess knee ROM by Electrogoniometer, hamstring flexibility by Sit and Reach Flexibility Test, stability index by Biodex Balance System and functional performance by WOMAC scale.
