Comparing Two Muscle Relaxation Techniques for Neck Pain (PRT-PIR-LS)

August 11, 2026 updated by: Dr Waqar Younas, University of Faisalabad

Comparative Effectiveness of Positional Release Technique and Post Isometric Relaxation on Pain, ROM and Functional Disability in Patient With Levator Scapulae Tightness

Levator scapulae muscle tightness is a common cause of neck pain due to poor posture. This study compares two manual therapy techniques: Positional Release Technique (PRT) and Post Isometric Relaxation (PIR). The goal is to determine which technique is more effective at reducing pain, improving neck range of motion, and decreasing functional disability in patients with this condition. Participants will be randomly assigned to receive either PRT or PIR for 4 weeks

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a double-blind, randomized clinical trial. A sample of 44 participants aged 25-40 with levator scapulae tightness will be recruited from hospitals in Faisalabad. Participants will be randomly assigned to two groups (n=22 each). Group A will receive the Positional Release Technique (PRT) involving a 90-second hold of the scapula in a specific position. Group B will receive Post Isometric Relaxation (PIR) involving a 10-second contraction followed by a 10-second stretch. Both groups will receive a 10-minute hot pack before their respective techniques. Interventions will occur 3 times per week for 4 weeks (12 sessions total). Outcome measures include the Numeric Pain Rating Scale (NPRS), cervical goniometry, and the Neck Disability Index (NDI), measured at baseline and after 4 weeks

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age between 25 to 40 years.
  • Both male and female.
  • Presence of a trigger point in levator scapulae (palpable tender spot with jump sign).
  • Score greater than 20% on the Neck Disability Index.
  • Non-specific neck pain.
  • Confirmation of trigger point via leavtor scapule length test.
  • trevors and simons criteria.
  • Jump sign

Exclusion Criteria:

  • History of trauma or fracture to the scapula or cervical spine.
  • Pregnancy.
  • Previous cervical spine surgery.
  • Diagnosis of cancer, cardiac condition, or infectious disease.
  • Specific neck pathology (e.g., disc prolapse, nerve root compression, whiplash).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Positional Release Technique (PRT)
Patient lies prone. The therapist palpates the levator scapulae and uses the far hand to translate the scapula upward and apply rotation. The superior angle of the scapula is tilted downward. This position is held for 90 seconds. 10 repetitions for 3 sets per session
Procedure: Positional Release Technique
Patient lies prone. The therapist palpates the levator scapulae and uses the far hand to translate the scapula upward and apply rotation. The superior angle of the scapula is tilted downward. This position is held for 90 seconds. 10 repetitions for 3 sets per session.
Active Comparator: Post Isometric Relaxation (PIR)
Patient lies supine. The therapist stabilizes the shoulder and supports the neck. The patient performs an isometric contraction by moving the head back against resistance for 10 seconds. After relaxation, a passive stretch is applied for 10 seconds. 10 repetitions for 3 sets per session.
Procedure: post isometric relaxation
Patient lies supine. The therapist stabilizes the shoulder and supports the neck. The patient performs an isometric contraction by moving the head back against resistance for 10 seconds. After relaxation, a passive stretch is applied for 10 seconds. 10 repetitions for 3 sets per session.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Pain Intensity
Time Frame: Baseline and at 4 weeks (post-intervention)
Measured using the Numeric Pain Rating Scale (NPRS). Participants rate their average neck pain on an 11-point scale where 0 = 'no pain' and 10 = 'worst imaginable pain'
Baseline and at 4 weeks (post-intervention)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Cervical Range of Motion
Time Frame: Baseline and at 4 weeks (post-intervention)
Measured using a universal goniometer. Active range of motion will be assessed for cervical flexion, extension, lateral flexion, and rotation, measured in degrees
Baseline and at 4 weeks (post-intervention)
Change in Functional Disability
Time Frame: Baseline and at 4 weeks (post-intervention)
: Measured using the Neck Disability Index (NDI), a 10-item questionnaire. Total scores range from 0 (no disability) to 50 (complete disability), reported as a percentage
Baseline and at 4 weeks (post-intervention)
