Overview

effects of Instrument Assisted Soft Tissue Mobilization (IASTM) and Post-Isometric Relaxation (PIR) in reducing pain, improving range of motion, and enhancing function among individuals with trapezius myalgia. it was a randomized clinical trial with outcome measuring tools as NPRS for pain Goniometer for ROM NDI for function

A randomized clinical trial was carried out over ten months at Arif Memorial Teaching Hospital in Lahore. The study included 48 participants aged between 25 and 35 years, selected through non-probability convenience sampling; 44 completed the full treatment. Participants were randomly divided into two groups of 22 each using a lottery method. Group A underwent IASTM combined with passive and self-stretching exercises, while Group B received the PIR technique. Both interventions were administered three times weekly for six weeks. Outcomes were assessed using the Numeric Pain Rating Scale (NPRS) for pain, a universal goniometer to measure cervical lateral flexion and rotation range of motion, and the Neck Disability Index (NDI) to evaluate functional limitations. Evaluations were performed before treatment and again at the end of the six-week intervention. Data analysis was conducted using SPSS-25, involving the Shapiro-Wilk test to assess normality, independent t-tests and Mann-Whitney U tests for intergroup comparisons, and paired t-tests along with Wilcoxon Signed Rank tests for intragroup analysis.

Inclusion Criteria: * Individuals aged 25 to 35 experiencing trapezius myalgia, * both men and women who report neck pain and stiffness, * Limited range of motion in lateral neck bending and rotational movement. * Presence of identifiable tender areas or trigger points within the trapezius muscle, Evidence of muscle tightness observed during mobility assessments, such as when performing lateral head tilt. * A firm band of muscle tissue containing a hypersensitive point, often with a palpable nodule and potential for radiating discomfort. Exclusion Criteria: * Traumatic injury to the neck causing torticollis, * Tumor affecting the upperportion of the trapezius muscle, * Cervical nerverootirritation or damage, Break in one or more cervical vertebrae, * Impairment of nervous system function, * Swelling and hypersensitivity reactions in the skin, * Abnormal spinal curvature and birth-related structural defects.

Outcomes

Primary Outcomes

Numeric Pain Rating Scale

The pain intensity was assessed using Numeric Pain Rating Scale (NPRS) an 11-point (0-10) tool used to measure a patient's pain intensity, where 0 means "no pain" and 10 means "the worst pain imaginable

Time frame: Baseline and after 6 weeks

Secondary Outcomes

Range of Motion

ROM was measured using goniometer

Time frame: Baseline and after 6 weeks

Neck Disability Index

The functions of neck was assessed using Neck Disability Index (NDI); The NDI is a 10-item patient-reported questionnaire designed to assess how neck pain affects daily activities such as personal care, lifting, reading, concentration, work, driving, sleeping, and recreation. Each item is scored from 0 (no difficulty) to 5 (maximum difficulty), giving a total raw score ranging from 0 to 50. The raw score is often converted to a percentage to standardize interpretation: NDI Percentage = (Total Score ÷ 50) × 100

Time frame: baseline and after 6 weeks
