Differences between Influence of Delorme and Oxford Method for Strengthening Knee Muscle to Reduce Disability of Osteoarthritis Patient in Datu Beru Takengon Hospital

Introduction Osteoarthritis is a degenerative joint impairment that usually occurs in elderly or adults who have degenerative cartilage accompanied by reactive changes on subchondral bone. This impairment is a common type of arthritis that usually happens and provokes pain as well as loss of functional movement. The prevalence of osteoarthritis is relatively high. WHO suggests that 25 % people with age of 65 years old has suffered from osteoarthritis, while in Southeast ASIA region, people that suffered from osteoarthritis is about 24 million. Knee muscles strength can be increased through strengthening exercise. General purpose of strengthening program is to improve performances and improve muscle function so that the disability index of osteoarthritic patient can be reduced. Method this study was an experimental study with two groups of pre and post test control group design. Subjects on this study was osteoarthritic patients undergoing physiotherapy rehabilitation of Datu Beru Takengon Hospital.36 subjects were into two groups, group I was applied with Delorme muscle strengthening exercise program and group II was applied with Oxford muscle strengthening exercise. Disability index measured by Lequesne index form, Lequesne index measure before and after treatment. Result there was a significant difference after muscle strengthening exercise in both groups. Group I showed a significant difference with mean value Lequesne index 9.42 0.988 while in group II showed mean value 9.47 0.866. Hypothetical analysis using independent t test did not find any significant differences of Lequesne index in both groups with p value p = 0.91. Conclusion Delorme and Oxford exerrt similar beneficial effects in reducing disability index.
