About

Chronic low back pain (CLBP) presents a significant therapeutic challenge due to its multifactorial nature and high recurrence rate. While manual therapy techniques like Positional Release Technique (PRT) are commonly employed to modulate pain and improve tissue function, there is a growing consensus in rehabilitation that their effects may be transient if not coupled with active strategies to address underlying impairments. Therapeutic exercises (TE) form a cornerstone of CLBP management by aiming to restore strength, endurance, and neuromuscular control. However, the specific additive benefit of combining a passive, indirect technique like PRT with a structured TE program remains an area for empirical investigation. This study, therefore, sought to compare the clinical effectiveness of an integrated approach using PRT alongside TE against the application of PRT alone, hypothesizing that the combined intervention. would yield superior outcomes in pain reduction and functional improvement for individuals with CLBP.

Full description

Background & Rationale:

Chronic low back pain (CLBP) is complex and prone to recurrence, making its management difficult. Clinicians often use passive manual therapies like the Positional Release Technique (PRT) to reduce pain. However, evidence suggests that passive treatments alone may not provide long-term relief unless combined with active interventions. Therapeutic exercise (TE) is a fundamental active approach that targets core deficits in strength and motor control. The key question is whether adding TE to PRT offers a significant advantage over PRT used in isolation.

Aim:

This study aimed to directly compare the clinical effectiveness of a combined treatment (PRT + TE) versus PRT alone in managing CLBP, with the hypothesis that the combined approach would be superior.

Methodology:

A randomized controlled trial was conducted with 60 participants diagnosed with CLBP (pain duration ≥3 months), aged 20-65. They were recruited from a single physiotherapy center. Participants with specific spinal pathologies (e.g., fractures, disc abnormalities) were excluded. They were randomly divided into two groups:

Group A (Experimental): Received PRT combined with a structured Therapeutic Exercise program.

Group B (Control): Received PRT alone.

Outcome Measures:

Effectiveness was assessed using standardized tools measured before and after the treatment period:

Pain Intensity: Visual Analogue Scale (VAS). Functional Disability: Roland-Morris Questionnaire (RMQ). Muscular Performance: A curl-up test for abdominal endurance.

Enrollment: 60 patients

Sex: All

Ages: 20 to 65 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Participants aged 20-65 years.
• Clinical diagnosis of chronic low back pain (CLBP).
• Positive Faber (Patrick's) test.
• Positive Slump test.
• A pain intensity score of ≥3 on the Visual Analogue Scale (VAS).
• Symptoms presenting with or without referred leg pain.

Exclusion criteria

• Diagnosis of spondylolisthesis, disc disease, osteoporosis, or other significant bone disease.
• History of vertebral fractures.
• History of spinal surgery.

60 participants in 2 patient groups

arm 1- Group A (PRT): Positional Release Technique with exercises

Experimental group

Description:

Group A (n=30) underwent a 12-session program over four weeks. Each 40-minute session combined two 30-minute positional release procedures with three 10-minute therapeutic exercise modules.

arm 2- Group A (PRT): Positional Release Technique without exercises

Experimental group

Description:

Group B received 12 treatment sessions over four weeks (three sessions/week), each consisting of two positional release procedures totaling 30 minutes.

Treatment:

Other: PRT Without exercises
