To compare the effect of dynamic and isometric resistance exercise using theraband on pain and functional ability in Elderly patient with OA knee in which the subject were challenged to perform the functional tasks including the joints to move over a wide range of motion as an outcome.

Design of study was experimental.

30 subjects having OA knee with mean age (58.3±5.8) at AIIMS New Delhi were included in the study.

Subjects were randomly allocated in two groups performed Dynamic or Isometric resistance exercises using Theraband (Total 6 exercises) for 6 muscle group of lower limb i.e. ankle planterflexors and dorsiflexors, knee flexors and extensors, hip flexors and extensors bilaterally. 1 set of 8 repetitions in 1and 2week and 3 set of 12 repetitions in 3and 4^th week for 4 weeks. Isometric resistance exercise group performed the exercise by positioning the joint at a predetermined angle i.e. 0° of Dorsi flexion and planter flexion when performing ankle planter flexion and dorsi flexion, 10° of knee flexion when performing knee flexion and extension and 10°of hip extension when performing hip flexion and extension.

Data was analysed using SPSS 11.5 software. Independent t test was used to compare the difference between groups. The significant level set for the study was p value ≤ 0.05.with in group analysis comparison was done using one way ANOVA for VAS and Time difference at 0^th, 2and 4^th week. Post hoc analysis of VAS and time has been done using LSD at 0^th, 2^nd and 4^th week. The level of significance was set at p<0.05.

Study found a significant time difference between groups while performing activities that need wider ROM which are standing from tailor position and raising from low stool and no significant difference in decline in pain between the 2 groups whereas pain declines significantly in both groups.

Both the groups showed meaningful improvement in pain while dynamic exercise group results in greater gain in functional ability that require wide ROM isometric exercise group. This suggest that dynamic resistance exercises are more beneficial in improving the function ability of the patient.
