Description

Background: Individuals with knee osteoarthritis (OA) might not be comfortable with vigorous manual therapy approaches due to severe pain. Complementary therapies can be effective in such situations. Task specific exercise training (TSET) and graded motor imagery (GMI) are two such therapies which are less explored for their effectiveness in knee OA. So, the aim of this study was to determine and compare the effects of TSET and GMI on pain, function, task performance, mobility and muscle torque in knee OA. Methods: Thirty-two individuals aged 40-65 years with grade 2 and above knee OA and pain intensity of > 4 on verbal scale were randomly assigned to TSET (n=16) and GMI (n=16) groups who received intervention thrice a week for 3 weeks. Pre (session 1) and post (session 9) outcome analysis was done for pain intensity by Numerical Pain Rating Scale, Knee injury and osteoarthritis outcome score for quality of life (QOL), three performance-based tests [30-second chair climb test, timed stair climb test and floor transfer test], peak torque and ratio for quadriceps and hamstrings using Isokinetic testing system and knee range of motion by goniometry. Results: Statistically significant difference was seen within both groups for all the outcomes (P<0.05). Both groups were equally effective for pain (P= 0.731), QOL (P=0.863) as well as all the objective based outcomes (performance-based tests, knee ROM, peak torque and ratio) Conclusion: Both TSET and GMI are effective complementary therapy approaches to treat knee OA in terms of pain, function and task performance.

It was a primary data collection. Osteoarthritis knee was the target population. Interventions were Task specific motor exercise training compared with motor imagery to manage pain and functions. Intervention was for 3 weeks. The highlight of interventions was that both were forms of complementary therapies.
