Effect of kinesio taping and exercise on functional impairment in patients with different degrees of knee osteoarthritis

BACKGROUND: Kinesio Taping (KT) is used for musculoskeletal problems. KT optimizes and reduces mechanical stresses on soft tissues. However, the benefits of KT and traditional exercises for different severities of knee osteoarthritis (OA) remains controversial. OBJECTIVES: This study aimed to investigate the effects of tension KT and traditional physical therapy on different severities of knee OA. METHODS: Fifty-six male patients with knee OA, aged 60–75-y years, were allocated to groups A and B based on grades 1 and 2 and grades 3 and 4 on the Kellgren-Lawrence scale, respectively. Tension KT and traditional physical therapy were administrated to both groups for 6-wks. The extensor peak moment of quadriceps and knee flexion range of motion (ROM) were recorded using an isokinetic dynamometer and universal goniometer, respectively. Visual analog scale (VAS) was used to score pain level. Statistical analysis was performed using the ANCOVA test. RESULTS: ANCOVA revealed an increase in peak extensor moment of quadriceps (Pre: 51.6 ± 2.8 Nm; Post: 63.3 ± 4.3 Nm), knee flexion ROM (Pre: 112.8±∘ 7.2; Post: 122.9±∘ 4.8), and pain improvement (Pre: 5.1 ± 1.07; Post: 2.8 ± 1.6) in group A (p< 0.001). Group B showed insignificant improvements in all outcome measures (p> 0.05). CONCLUSION: KT with traditional physical therapy improved knee pain, quadriceps strength, and knee ROM in older males with knee OA grades 1 and 2. KT and traditional physical therapy were insufficient to produce considerable effects on grades 3 and 4 of knee OA.
