To investigate the relationships among chronic low-back pain and obesity, total spinal range of motion, and trunk muscle strength. The short-term impact of trunk muscle strengthening exercises on this condition was also examined.
A controlled, prospective study of trunk muscle strengths of patients with chronic low-back pain and the short-term impact of exercise on strength. The study group consisted of 25 female patients who had been experiencing low-back pain for at least 3 mo, and the control group included 20 age-matched women without known low-back trouble. The Davenport Index was used to calculate the body mass indexes of all subjects. The Oswestry Disability Questionnaire was used to assess pain in the study group. Full flexion and extension ranges of motion were measured, then isokinetic measurements of trunk muscles were performed at 60-, 120-, and 180-degrees/sec velocities. Isometric measurements were also recorded for both flexors and extensors at a 60-degree angle.
Increased body mass index and decreased trunk muscle strength were found to be directly associated with chronic low-back pain (P < 0.05). After a 15-day standard trunk strengthening exercise program in the patient group, trunk muscle strength was found to be increased (P < 0.05).
Obesity and decrease in trunk muscle strength are important factors in chronic low-back pain, and a trunk muscle strengthening program will be helpful in reducing the pain.
研究慢性下腰痛与肥胖、脊柱总活动范围及躯干肌肉力量之间的关系。还研究了躯干肌肉强化训练对这种情况的短期影响。
一项关于慢性下腰痛患者躯干肌肉力量及运动对力量的短期影响的对照前瞻性研究。研究组由25名经历下腰痛至少3个月的女性患者组成，对照组包括20名年龄匹配且无已知下腰痛问题的女性。使用达文波特指数计算所有受试者的体重指数。使用奥斯威斯利残疾问卷评估研究组的疼痛情况。测量脊柱的全屈和全伸活动范围，然后以60度/秒、120度/秒和180度/秒的速度对等速测量躯干肌肉。还记录了屈肌和伸肌在60度角时的等长测量值。
发现体重指数增加和躯干肌肉力量下降与慢性下腰痛直接相关（P < 0.05）。在患者组进行15天的标准躯干强化训练计划后，发现躯干肌肉力量增加（P < 0.05）。
肥胖和躯干肌肉力量下降是慢性下腰痛的重要因素，躯干肌肉强化训练计划有助于减轻疼痛。
