简要总结
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.
详细描述
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.

研究组 & 干预措施
arm 1- Group A (PRT): Positional Release Technique with exercises
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.
干预措施: PRT with exercises (Other)
arm 2- Group A (PRT): Positional Release Technique without exercises
Group B received 12 treatment sessions over four weeks (three sessions/week), each consisting of two positional release procedures totaling 30 minutes.
干预措施: PRT Without exercises (Other)
结局指标
主要结局
VAS
时间窗: 4 weeks
A validated, single-item scale used to measure subjective pain intensity. Patients mark a point on a 10-cm line anchored by "no pain" (0) and "worst pain imaginable" (10). The score is the measured distance in cm/mm, providing a quantitative pain rating.
RMQ
时间窗: 4 weeks
The Roland-Morris Disability Questionnaire (RMQ) is a widely used, self-administered, health status measure designed to assess physical function and disability specifically related to low back pain. It consists of 24 yes/no statements derived from the Sickness Impact Profile, each describing a specific activity limitation due to back pain (e.g., "I walk more slowly because of my back"). The total score (0-24) is the sum of items marked "yes," with a higher score indicating greater disability. It is valued for its brevity, ease of use, and responsiveness to clinical change.
Endurance
时间窗: 4 weeks
An endurance test is a performance-based assessment that measures the ability of specific muscle groups (particularly the trunk stabilizers: back extensors, flexors, and lateral musculature) to maintain a submaximal contraction or a fixed posture against gravity over time. Common examples used in low back pain research include the prone plank (trunk flexors), Sorensen/Biering-Sørensen test (back extensors), and side plank (lateral stabilizers). The outcome is the time (in seconds) the position can be held until failure, providing an objective measure of muscular stamina.
