FUNCTIONAL PERFORMANCE MEASUREMENT IN DEGENRETIVE KNEE OSTEOARTHRITIS COMPARED TO HEALTHY INDIVIDUALSOBJECTIVE: To measure the functional performance in people suffering from degenerative knee osteoarthritis compared with control group consisting of healthy individuals.BACKGROUND: Physical activity is so crucial to optimal health outcomes, there are now federal recommendation for the general public, including those with arthritis. Physical Activity Guidelines Advisory Committee. Physical Activity Guidelines Advisory Committee report, 2008. Washington: Dept. of Health and Human Services; 2008There is a gap in the OA literature with regard to the relationship between different doses of physical activity and health outcomes. The research priorities listed by the Department of Health and Human Services in its physical activity guideline report include the need to identify physical activity doses that can result in beneficial disease-specific outcomes.Physical Activity Guidelines Advisory Committee. Physical Activity Guidelines Advisory Committee report, 2008. Part H: Research recommendations. Washington: Dept. of Health and Human Services; 2008.Understanding the nature of the relationship between physical activity and function has important public health implications related to developing physical activity guidelines and clinical implications for counseling knee OA patients, particularly those for whom a recommended physical activity threshold appears unreachable.Physical Activity Levels and Functional Performance in the Osteoarthritis Initiative. Dorothy D. Dunlop, Jing Song, Pamela A. Semanik, Leena Sharma,1 and Rowland W. Chang. ARTHRITIS & RHEUMATISM.Vol. 63, No. 1, January 2011, pp 127136METHOD: Patients coming to SRI RAMACHANDRA HOPITAL PHYSIOTHERAPY OP with diagnosis of degenerative osteoarthritis will be included in the study within the age group of 40 50 yrs. Control group will be patients who has complains of no knee pain witin age group of 40-50 yrs. Functional performance will be assessed using the stair-climbing test, timed up-and-go test, 6-minute walk test, and single-limb stance time.Measures of functional performance included the timed up-and- go test (TUG), stair climbing test (SCT), 6-minute walk test (6MW), and single-limb stance (SLS) time. The TUG measures the time to rise from an arm chair (seat height, 46 cm), walk 3 m, turn, and return to sitting in the same chair, without physical assistance. This test has excellent interrater and intrarater reliability, with an ICC of 0.99, as measured in a group of 60 community-dwelling older adults. The SCT measures the time to ascend and descend a flight of stairs. The SCT measures a higher level of activity and has been shown to correlate to the TUG test. Because this test is considered more challenging than the TUG, it reduces the possibility of a ceiling effect. Patients were tested on a 10-step stair case with 17.1-cm step height. The 6MW measures the total distance walked in meters over 6 minutes. This test has been used extensively to measure endurance and has been validated as a measure of functional performance following knee arthroplasty. The 6MW test has excellent test-retest reliability, with ICCs from 0.95 to 0.97, and a low coefficient of variation (10.4%). Singlelimb stance time was used to assess static postural control of the surgical side. The test duration was limited to a maximum of 30 seconds, and the longest duration of the 2 trials was recorded. This measure is used commonly for clinical assessment and has test-retestreliability of 0.78.
