Comparative analysis of instrument-assisted soft tissue mobilization and traditional physical therapy on pain and functional outcomes in knee osteoarthritis patients

Abstract

Athletes frequently confront the daily obstacles and training interruptions caused by patellofemoral pain syndrome. The therapist in group A applied the treatment area at a 45-degree inclination, followed by 30 gentle strokes from the instrument's tip to the implant. Part B engaged in three rounds of PNF stretching, incorporating a 10-second interval between each round, after an 8-second duration of prolonged isometric contraction of the hamstring at about 50% of maximal strength prior to release. Every patient participated in a 30-minute session thrice weekly for a period of six weeks. The outcome metrics including the WOMAC, which gauges the health status of KOA patients, AKT, which analyses hamstring flexibility, and VAS, which measures pain intensity, are two of these evaluations. A statistically significant interaction (p < 0.001) was identified in the study concerning treatments and various metrics throughout time. After a period of 6 weeks, both treatments demonstrated significant improvements; however, group A (IASTM) exhibited markedly superior outcomes in hamstring flexibility, pain reduction, and general well-being (p < 0.001) relative to group B (PNF). Engaging in PNF and IASTM stretching resulted in enhanced hamstring flexibility, less discomfort, and improved overall well-being. The IASTM method demonstrates more benefits than PNF stretching in terms of mobility, alleviation of discomfort, and promotion of community health. The IASTM technique might be used by physical and manual therapists when addressing individuals desiring significant enhancements in these areas.
