Effectiveness of Reciprocal Inhibition and Post-Isometric Relaxation Technique in the Management of Upper Trapezitis

BACKGROUND: Upper trapezitis, marked by pain and tightness in the upper trapezius muscle, is a frequent musculoskeletal issue typically linked to poor posture, overuse, and stress. Post-isometric relaxation (PIR) and reciprocal inhibition (RI) are well-known therapies used for relieving pain and tension in the muscles. Combining these techniques may offer synergistic benefits in managing upper trapezitis, but the evidence supporting their effectiveness remains unclear. Methods: The study involved a total of 90 participants, with 45 individuals in each of the two groups. Group A consisted of 45 subjects who received the Reciprocal Inhibition (RI) technique, while Group B comprised 45 subjects who underwent the Post-Isometric Relaxation (PIR) technique. Male and female participants, aged 20 to 40 years, were chosen according to the inclusion criteria. They were clinically diagnosed with upper trapezitis, assessed using the NDI scale and a pressure algometer as outcome measures. Results: PIR group had significant improvement with a mean (21.93) in reducing the pain and mean (16.60) in improving the functional ability of neck in people with upper trapezitis with a p-value <0.0001. CONCLUSION: Among people with upper trapezitis, the Post-Isometric Relaxation treatment regimen has shown greater effectiveness in reducing discomfort and improving functional outcomes.
