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

8. juni 2026 opdateret af: 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

Detaljeret beskrivelse

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

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: 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.
Aktiv komparator: 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.
