IMMEDIATE AND SHORT TERM EFFECTS OF MULLIGAN MOBILIZATION WITH MOVEMENT, ON PAIN, DISABILITY AND RATIO OF VASTUS MEDIALIS AND VASTUS LATERALIS ACTIVITY IN INDIVIDUALS WITH KNEE OSTEOARTHRITIS IN THE AGE GROUP 50-70 YEARS.

Abstract

Knee osteoarthritis is a common cause of knee pain and functional impairment. In this study immediate and short term effect of Mulligan mobilization with movement (MWM) technique on Pain,disability,and ratio of vastus medialis and vastus lateralis activity were assessed on 40 individuals with knee osteoarthritis in the age group of 50-70 years. Method- Duration of study for each participant was 2 weeks which included 4 sessions- on day 1,3,5 and 12.Immediate effect was assessed immediately after each treatment session and short term effect was assessed one week after the nal treatment session i.e on day 12.Outcome measures were Numerical Pain Rating Scale,Knee outcome Survey and EMG activity of vastus medialis and vastus lateralis. Result-Signicant immediate effect of MWM on pain was obtained in every session.(p<0.0001).There was signicant short term effect of Mulligan on pain. (p<0.0001).Signicant effect of MWM on disability reduction was also seen (p<0.0001). There was no immediate or short term effect of MWM on ratio of EMG activity of vastus medialis and vastus lateralis muscles.(p=0.5) Conclusion- Mulligan MWM has immediate and short term effect on pain and disability but not on ratio of vastus medialis and vastus lateralis activity in individuals with knee osteoarthritis in the age group of 50-70 years.
