Trapezitis is an inflammatory pain arising from the trapezius muscle causing a severe neck spasm. Trapezius muscle pain and spasm is most common musculoskeletal disorder occurring in individuals who works with an awkward position of neck for a prolonged period of time, with repetitive movements. Neck pain is very commonly shown by most people to be in the region of the back of the neck and between the bases of the neck to the shoulder, primarily indicating the upper region of the trapezius muscle.


A study to determine the effect of post isometric relaxation in trapezitis among office workers.


A convenient sample of 20 subjects selected from the study, any person from 25 to 40 years complaining of pain in the side of the neck and shoulder in unilateral and bilateral for last 3 days. Subjects to males and females were screened as in acute stage patient with painful trapezius muscle and restricted range of motion in shoulder elevation movements. The participants were asked to fill the questionarrie from trapezius muscle pain symptoms and intensity and severity of pain experienced. Subjects were allocated into 2 groups. GROUP A -conventional physiotherapy alone GROUP B -post isometric relaxation with conventional physiotherapy.

Outcome Measures

Visual analog scale, Neck disability index (NDI).


The data obtained was tabulated and statistically analysed. Due to the nature of outcome measures that is pain and disability measured by pre and post intervention parametric statistical test, unpaired T test were used. The two-tailed P value is less than that of0.001. By the conventional criteria is difference and it is considered to be statistically significant in experimental group.


PIR is more effective therapeutic maneuver. PIR were found to be effective in improving trapezius muscle flexibility and also increases the muscle strength.
