简要总结
Mechanical low back pain (LBP) stems from spinal structures or surrounding tissues, often caused by overuse or trauma, and is prevalent globally with high recurrence rates. Key contributing factors include biomechanical, psychological, and social elements. The latissimus dorsi (LD), along with other back muscles, plays a crucial role in lumbar stability via the thoracolumbar fascia. Stretching the LD has shown positive effects in reducing pain and improving function in chronic LBP patients. Physical therapy treatments include manual therapy, core stabilization, and flexibility exercises. Muscle Energy Techniques (MET), particularly targeting the LD, can enhance flexibility and spinal mobility when applied correctly.
详细描述
Mechanical low back pain (MLBP) originates from structural components of the spine, such as intervertebral discs, muscles, ligaments, or joints, and is commonly caused by repetitive trauma, poor posture, or overuse. It is a leading cause of functional disability worldwide, with high recurrence rates. Physiotherapy plays a central role in managing MLBP by addressing contributing biological, psychological, and social factors. The latissimus dorsi (LD) muscle, due to its anatomical connection with the pelvis via the thoracolumbar fascia (TLF), significantly influences lumbar stability. Impaired extensibility or overactivity of the LD can contribute to mechanical dysfunction. Incorporating LD stretching into rehabilitation protocols has shown enhanced outcomes in pain reduction and functional improvement. Muscle Energy Techniques (MET), particularly Post Facilitation Stretching, utilize controlled muscle contractions to improve flexibility and relieve tension in shortened muscles. Proper application of MET targeting the LD has demonstrated effectiveness in increasing range of motion and supporting spinal stability in patients with chronic low back pain.

研究组 & 干预措施
Conservative physical therapy
Hot pack + TENS (10 min), followed by a structured program of warm-up, 20-minute core/back strengthening, stretching (hip flexors, hamstrings, lumbar extensors), and cool-down exercises.
干预措施: Conservative physical therapy (Procedure)
Post facilitation stretch of latissimus dorsi with conservative physical therapy
Receives the same conservative physical therapy as the control group plus Latissimus Dorsi Muscle Energy Technique (isometric contraction for 10seconds, relaxation 2-3seconds, followed by 10seconds stretch, applied bilaterally each session).
干预措施: Post-facilitation stretch of latissimus dorsi with conservative physical therapy (Procedure)
结局指标
主要结局
Low back pain
时间窗: 4 weeks
Numeric Pain Rating Scale will be used. An 11-point scale comprising a number from 0 through 10; 0 indicates "no pain", and 10 indicates the "worst imaginable pain". Patients are instructed to choose a single number from the scale that best indicates their level of pain.
Functional Disability of back
时间窗: 4 weeks
Oswestry disability index will be used. To evaluate the functional impact of low back pain on a person's daily life. It consists of 10 items on the degree of severity to which back (or leg) trouble has affected the ability to manage in everyday life. The 10 sections cover the pain and the daily function (including pain intensity, personal hygiene, lifting, walking, sitting, standing, sleeping, sexual activity, social activity, and traveling). Each item is rated on a 6-point scale (0-5); the higher score means the higher level of disability related to LBP. The present study used the traditional Chinese version of the ODI 2.1
Range of motion of low back.
时间窗: 4 weeks
Dual Inclinometer will be used. It is a handheld, circular, fluid-filled disc that has a weighted gravity pendulum attached to it that is maintained in the vertical direction. It is graduated by 0.5 degree intervals over 360.
