The Effectiveness of IASTM Versus Static Stretching in Improving Hamstring Flexibility Along with Quadriceps Strengthening Exercises, Tens in Patients with Osteoarthritis Knee

Abstract

Background: Osteoarthritis (OA) of the knee is prevalent in the elderly and causes pain, stiffness, and functional
limitations. Hamstring inflexibility and weakened quadriceps worsen OA progression. Hence, Therapeutic
interventions like IASTM and Static Stretching show potential in addressing musculoskeletal issues.
Objective: This study aimed to investigate and compare the effectiveness of IASTM versus Static Stretching, along
with quadriceps strengthening exercises and TENS, in improving hamstring flexibility, and quadriceps strength,
and reducing pain in patients with knee OA.
Methodology: A randomized controlled trial with 30 knee OA patients: Group A (n=15) received IASTM,
quadriceps strengthening exercises, and TENS; Group B (n=15) underwent Static Stretching, quadriceps exercises,
and TENS. Both groups underwent a six-week intervention program, with pre-and post-assessments using NPRS,
AKE Test, and WOMAC questionnaire.
Results: Significant differences were observed between Group A and Group B in NPRS, AKE Test, and WOMAC
scores (p < 0.0001). Group A exhibited lower values in NPRS, AKE Test, and WOMAC, indicating reduced pain,
improved knee function, and decreased discomfort compared to Group B. The combination of interventions in
Group A appeared to offer better outcomes for knee OA patients.
Conclusion: The study suggests that the combination of IASTM, quadriceps strengthening exercises, and TENS
(Group A) yields better outcomes in improving knee OA patients’ hamstring flexibility, quadriceps strength, and
pain reduction compared to Group B.
