Effect Of Strengthening Hip Rotators And Ankle Muscles On Knee Osteoarthritis

Knee Osteoarthritis Clinical Trial

Official title: Effect Of Strengthening Hip Rotators And Ankle Muscles On Knee Osteoarthritis

Status Completed

Clinical Trial Summary

The goal of this clinical trial is to investigate the effect of adding strengthening exercise for hip rotators and ankle muscles to knee exercises on pain, function, muscles strength , and knee proprioception in patients with knee osteoarthritis. The main question it aims to answer is: - What is the effect of adding strengthening exercise for hip rotators and ankle muscles to knee exercises on pain, function, strength of hip rotators and ankle muscles, and knee proprioception in patients with knee osteoarthritis?" Adult male and female diagnosed with unilateral or bilateral knee osteoarthritis, referred from orthopedic surgeons according to inclusion and exclusion criteria will be enrolled in this study, randomly allocated to groups and received exercise for 4 weeks. - Control group Patients in this group will receive knee exercises in the form of stretching for hamstring and calf. Strengthening exercises in form of strengthening exercise for quadriceps. - Experimental group In addition to the same knee exercise of control group patients will receive strengthening exercise for hip rotators and ankle muscles.

Clinical Trial Description

The purpose of the current study is to investigate the effect of adding strengthening exercise for hip rotators and ankle muscles to knee exercises on pain, function, strength of muscles, and knee proprioception in patients with knee osteoarthritis. Adult male and female diagnosed with unilateral or bilateral knee osteoarthritis, referred from orthopedic surgeons according to inclusion and exclusion criteria will be enrolled in this study, randomly allocated to groups and received exercise for 4 weeks. Control group Patients in this group will receive knee exercises in the form of stretching for hamstring and calf. Strengthening exercises in form of strengthening exercise for quadriceps. Experimental group In addition to the same knee exercise of control group patients will receive strengthening exercise for hip rotators and ankle muscles. Recruited subjects will be screened with consideration of the inclusion and exclusion criteria. Aim of the study and all testing procedures will be verbally explained for eligible subjects and all relevant questions will be answered. If they agreed to participate in the study, an informed consent will be signed . Then, basic demographic information will be collected and patients will start the test. We will measure pain using visual analogue scale, functional level of the knee using Arabic Knee injury and Osteoarthritis Outcome Score questionnaire, isometric muscle strength of quadriceps, hip external and internal rotators, dorsi flexors, planter flexors, evertors and invertor muscles of ankle will be measured by handheld dynamometer and finally knee proprioception will be measured by assessing joint position sense by digital inclinometer. All these measurements will be done at base line and after (4 week) at the end of the treatment program. All patients will receive knee exercises according to guidelines and previous studies in the form of strengthening exercises that progress from 50% of the 1. repetition maximum at first 2 week to 70% of 1 repetition maximum at last 2. weeks, and from mild and moderate Thera band resistance in the first 2 weeks to maximum resistance in the last 2 weeks. In addition to knee muscle strengthening exercises,the experimental group will receive hip rotators and ankle muscles strengthening exercises. Passive stretching for hamstring and calf muscles will be done at the end of all exercises. Stretching will be performed three repetitions per session, holding each stretch for 30 seconds, with 10-seconds rest in between. All exercises will be performed for 30 to 45 minutes per session, 3 times per week for 4 weeks (12 sessions). ;
