Impact of Instrument-Assisted Soft Tissue Mobilization Combined With Conventional Therapy On Calf Muscle Pain And Tightness Among Teachers.

Abstract

Teachers frequently engage in prolonged standing and repetitive lower-limb loading throughout their workday, placing continuous stress on the calf musculature. Over time, this strain can contribute to the development of myofascial trigger points, which are characterized by localized tenderness, increased muscle tightness, and referred pain. These symptoms may impair mobility, reduce occupational efficiency, and predispose individuals to chronic musculoskeletal conditions. Instrument-Assisted Soft Tissue Mobilization (IASTM) has emerged as a specialized manual therapy technique aimed at improving soft-tissue extensibility, reducing fascial adhesions, and enhancing tissue healing. Although IASTM has shown promising results in athletic and clinical populations, limited evidence exists regarding its effectiveness among teaching professionals, who represent a high-risk occupational group for lower-limb overuse injuries.

Objective: The present study aimed to examine the therapeutic impact of integrating IASTM with conventional physiotherapy approaches on reducing pain and muscle tightness in teachers diagnosed with calf myofascial trigger points. The study further sought to compare the outcomes between IASTM-assisted treatment and traditional physiotherapy alone.

Methods: A experimental study was conducted on 40 teachers aged 25–50 years who were clinically diagnosed with calf trigger points. Participants were randomly allocated into two groups:

Group A (Experimental): Received IASTM along with stretching, myofascial release, and strengthening exercises.

Group B (Control): Received only traditional physiotherapy interventions.

Pain levels were evaluated using the Visual Analog Scale (VAS), and muscle tightness was assessed through active ankle dorsiflexion range of motion (ROM). The intervention lasted for 2 weeks with five sessions per week. Pre- and post-treatment values were analyzed using paired and unpaired t-tests.

Results: Both groups demonstrated meaningful improvements following the intervention period; however, significantly superior outcomes were observed in Group A. Participants receiving IASTM exhibited a greater reduction in pain scores and a larger increase in ankle dorsiflexion ROM compared to the control group. The statistical analysis revealed a highly significant difference (p < 0.001) in favor of the IASTM group, indicating that the technique effectively enhances soft-tissue mobility and reduces myofascial sensitivity.

Conclusion: The findings of this study highlight the enhanced therapeutic value of incorporating IASTM into routine physiotherapy for the management of calf myofascial trigger points among teachers. By providing greater reductions in pain and muscle tightness, IASTM serves as an effective clinical adjunct capable of improving lower-limb function and addressing occupational musculoskeletal demands. Its application may help prevent chronic discomfort and improve overall physical well-being in teaching professionals
