OBJECTIVE: Compare the effectiveness of Open-chain and Close- chain kinematics exercises to enhance proprioception and functional knee flexion range in-patients with knee osteoarthritis. INTRODUCTION: Knee OA is most common form of degenerative, non- inflammatory disease .it is the most common form of arthropathy characterized by progressive damage to the articular cartilage and presenting features joint pain, tenderness and decrease ROM. Risk factors are multifactorial and include older age, female gender, obesity, previous joint injury, genetics & muscle weakness. It has being estimated that no. of people over 65 years will be double in the first two decades in the century. A survey in India in 2007 revealed the OA prevalence rate of 32.6% in rural and 60.3% in urban population. OA was present in 50.2% population falling in age group 65-74 years whereas it was 97.7% in age group of 84 years or older. Knee OA is likely to become the 8th most common important cause of disability in women according to the World Health Organization report on burden of disease. The rapid rise in the percentage of individuals above more than 55 years of ageing major health issue in public, affecting across 40 million people. METHADOLOGY: Total no of 40 subjects 9 male and 31 female were evaluated for the study age in (year), weight in (k.g.) and BMI (k.g./m 2) with age group between 47 to 74 years with mean age of 62.7± 8.5 years . Patients with knee OA had impaired proprioception, limited knee flexion range of motion and at least one knee assigned a K/L grade ≥2 that further met the inclusion-exclusion criteria chosen for the study. Total 40 patients divided into 2 equal halves of groups. Group A involved in close-chain exercises (kinesthesia and balance exercises) & Group B was involved in open-chain kinematics exercises (strengthening exercise). Their knee proprioception by reproductive test measurement (JPS) test preassumed with 400&600 ,pain on VAS were assessed pre exercises and post exercises. TECHNIQUE:8month experimental study conducted on 40 patients with knee OA is divided into 2 equal halves of size 20 by using Lottery method (simple random sampling technique) that constitutes two groups: Group A involved in close-chain exercises (kinesthesia and balance exercises) & Group B was involved in open-chain kinematics exercises (strengthening exercise). Both the groups received treatment for 3 weeks of 30 mints under the researcher’s supervision. However the descriptive statistical analysis had used to project the main features & characteristics of the patients with new osteoarthritis that analyzed for their pain on VAS, knee proprioception using reproductive test measurement (JPS) test presumed with 400 & 600by electronic goniometer and knee flexion range of motion using electronic goniometer assessed pre and post exercises intervention. RESULT: CONCLUSION: The study showed that proprioceptive perception is impaired with knee Group A and Group B both demonstrated significant improvement in pain on VAS,knee proprioception using reproductive test measurement (JPS) test presumed with 400 & 600 by electronic goniometer and knee flexion range of motion using electronic goniometer. Pain on VAS mean score 1.00 after intervention in group A close -chain exercises compared to Group B, knee flexion joint range of motion mean angle difference after intervention 9.350 in Group A close-chain exercises statistically highly significant (p<0.001) , proprioception measurement of joint position sense test reassumed angle with 400 and 600 . At angle 400 mean angle difference 6.20 points after post intervention in Group A and B . At angle 600 mean angle difference was 6.35 point in group A and group B ,Group A close-chain exercises statistically highly significant (p<0.001) .Therefore Group A has more effective result as compared to Group B in improvement pain on VAS , reproductive test measurement for knee proprioception, and functional knee flexion range in knee osteoarthritis patients. osteoarthritis and that this impaired in individuals with knee osteoarthritis and this impairment is large enough as it affects their functional performance. Both open- chain and close-chain kinematics exercises improve functional knee flexion range ,reduce pain and enhance proprioception but close-chain kinematics exercises more effective than open chain kinematics exercises to enhance proprioception and improve functional knee flexion range individual with knee osteoarthritis.
