The Effects of Functional Task Training versus Progressive Resistance exercises on OA Knee.

Aims & Objectives: To investigate the efficacy of functional task training in decreasing pain, and increasing functional mobility in Osteoarthritis Knee. Study design: Comparative case control study. Methodology: Thirty subjects with a diagnosis of OA Knee were selected directly from Physiotherapy outpatient door of Jaipur Physiotherapy College, MVGU, Jaipur. These individuals were randomly assigned into two groups: FTT Group [Functional task Training (n = 15)] and PRE Group [Progressive Resistance Exercise (n = 15)]. FTT Group Functional tasks included sit to stand box lift, standing star exercise, walking up and down a ramp while holding a weight, ascending/descending stairs while holding a weight in the preferred hand, and walking indoors while passing a weighted ball from hand to hand. Subjects performed the exercises for one minute with (when indicated) a one-pound weight. Progressions included either an increase in weight or time to perform the activity. Subjects in the PRE program performed three exercises (two exercises for quadriceps strengthening and one for hamstrings strengthening), for the first 6 weeks all the exercises were given with 1kg weight and for the next 6 weeks exercises were given with 1.5kg weight. Patients were instructed to do each exercise Twenty five to thirty repetitions in one set and single set is done by patient in one treatment session. Both the groups were given exercises supervised by physiotherapist on regular basis for 12 weeks. Data for measurements of pain on VAS scale, Balance & mobility on Step Test & Walking speed Test was collected on day 1 (pre treatment session), at 6 weeks, and at week 12. Results: Results indicate that both groups improved in all measures of pain, Balance and functional outcomes. However, upon intergroup analysis the mean changes in the score of VAS, Step Test & Walking Speed Test was highly significant across the two testing periods (at 6 week & 12 week) for the functional task training group (FTT). Conclusion: Functional task training on regular basis is an effective rehabilitation program and is better than PRE for improving functional mobility, balance and decreasing pain in OA Knee.
