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

Abstract: Introduction: Osteoarthritis is a degenerative joint impairment that usually occurs in elderly or adults who have degenerativecartilage 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 osteoarthritisis about 24 million. Knee muscles strength can be increased through strengthening exercise. General purpose of strengthening programis 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 osteoarthriticpatients 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 significantdifference after muscle strengthening exercise in both groups. Group I showed a significant difference with mean value Lequesne index9.42 ± 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 similarbeneficial effects in reducing disability index.
