Psoas Major Muscle Intervention on Chronic Lumbar Pain in Cleaning Professionals.
Influence of the Stretching Technique on the Psoas Major Muscle on Chronic Lumbar Pain in Cleaning Professionals: Randomized Controlled Trial.
調査の概要
詳細な説明
Cleaning professionals are particularly vulnerable to musculoskeletal pain, predominantly low back pain due to intense occupational hazards like repetitive movements, heavy lifting in awkward postures, and prolonged standing. The psoas major muscle plays a critical role in this clinical context; morphological changes, such as muscle atrophy and fat infiltration, are commonly observed in low back pain patients. Furthermore, a shortened or asymmetrical psoas alters spinal biomechanics-often increasing lumbar lordosis and overloading facet joints-which strongly predisposes individuals to chronic pain and instability. Furthermore, a shortened or asymmetrical psoas alters spinal biomechanics-often increasing lumbar lordosis and overloading facet joints-which strongly predisposes individuals to chronic pain and instability.
This study aims to highlight the biomechanical importance of the iliopsoas muscle and evaluate the therapeutic impact of the stretching technique in reducing symptoms, improving mobility, and preventing functional limitations associated with iliopsoas dysfunction.

プラセボコンパレーター:対照群
|
Patient is positioned supine at the edge of the table.
The investigator places one hand on the participant's ipsilateral knee without applying any pressure or force, and the other hand on the contralateral knee for stabilization.
This position is maintained for 30 seconds to match the duration of the experimental intervention.
The technique was performed bilaterally (once on each side) to the control group.

実験的:Experimental group
Psoas major stretching
|
The patient is positioned supine at the edge of the table.
The investigator places their hands on both of the participant's knees, applying gentle downward pressure on the ipsilateral knee to stretch the psoas major muscle.
This stretch is held for 30 seconds and performed bilaterally (once on each side) to the experimental group.

Low Back Pain Intensity at Rest Assessed Using the Numeric Pain Rating Scale (NPRS, 0-10)
時間枠:Baseline and immediately after completion of the intervention.
|
Low back pain intensity at rest will be assessed using the Numeric Pain Rating Scale (NPRS), a self-reported scale ranging from 0 to 10, where 0 indicates "no pain" and 10 indicates "worst imaginable pain."
Higher scores indicate greater pain intensity and therefore a worse outcome.
|
Baseline and immediately after completion of the intervention.

Lumbar Range of Motion Assessed Using the Schober Test
時間枠:Baseline and immediately after completion of the intervention.
|
Lumbar range of motion (ROM) will be assessed using the Schober Test at rest and during anterior lumbar flexion.
The test measures lumbar spine mobility by quantifying the increase in distance between predefined anatomical landmarks during trunk flexion.
Higher values indicate greater lumbar mobility and therefore a better outcome.
|
Baseline and immediately after completion of the intervention.

|
Hip Flexion Range of Motion Assessed Using a Digital Goniometer
時間枠:Baseline and immediately after completion of the intervention.
|
Hip flexion range of motion (ROM) will be assessed with the participant in the supine position using a digital goniometer.
Measurements will be recorded in degrees (°).
Higher values indicate greater hip flexion mobility and therefore a better outcome.
|
Baseline and immediately after completion of the intervention.
