To investigate the laser effect associated with stretching exercise on pain and functionality in patients with knee osteoarthritis.
A randomised controlled trial.
Special Rehabilitation Services.
We enrolled 215 knee osteoarthritis patients (430 knees were treated).
Group Laser + Stretch ( = 43), Placebo + Stretch ( = 43), Stretch ( = 43), Laser ( = 43) and Control ( = 43) were treated with active laser and stretching exercises; placebo laser and stretching exercises; stretching exercises; active laser, and control, respectively. Interventions were conducted 3 times a week for 8 or 11 weeks.
The primary outcome was the change in knee pain and disability. Secondary outcomes included severity of osteoarthritis, mobility, knee range of motion, flexibility, activity, severity of osteoarthritis and medication intake for pain relief.
The patients' average age was 63.52 (6.8) years. Pain scores at baseline and post treatment ( < 0.001) were 7.43 (2.10) and 2.79 (1.92) for group Laser + Stretch, 7.39 (1.98) and 4.47 (2.82) for group Placebo + Stretch, 6.83 (1.42) and 4.24 (2.43) for group Stretch, 6.61 (1.68) and 2.94 (2.65) for group Laser, 6.74 (1.75) and 6.47 (2.29) for group Control, respectively. Disability score at baseline and post treatment ( = 0.000237) were 12.36 (5.02) and 8.08 (4.64) for group Laser + Stretch, 12.71 (5.12) and 9.90 (4.95) for group Placebo + Stretch, 11.83 (2.77) and 7.20 (5.28) for group Stretch, 11.58 (5.59) and 8.21 (6.18) for group Laser, 11.23 (4.68) and 11.45 (4.83) for group Control, respectively.
Laser therapy combined with stretching exercises improves pain during rest, activities of daily living, stiffness, muscle shortening and range of motion in patients with knee osteoarthritis.
探讨激光联合拉伸运动对膝骨关节炎患者疼痛和功能的影响。
随机对照试验。
特殊康复服务。
我们招募了 215 例膝骨关节炎患者（共 430 个膝关节接受治疗）。
激光+拉伸组（ = 43）、安慰剂+拉伸组（ = 43）、拉伸组（ = 43）、激光组（ = 43）和对照组（ = 43）分别接受活性激光和拉伸运动治疗、安慰剂激光和拉伸运动治疗、拉伸运动治疗、活性激光治疗和对照组治疗。每周进行 3 次治疗，共进行 8 或 11 周。
主要观察指标为膝关节疼痛和功能的变化。次要观察指标包括骨关节炎严重程度、活动能力、膝关节活动范围、柔韧性、活动能力、骨关节炎严重程度和缓解疼痛的药物摄入。
患者平均年龄为 63.52（6.8）岁。治疗前后的疼痛评分（ < 0.001）分别为：激光+拉伸组 7.43（2.10）和 2.79（1.92），安慰剂+拉伸组 7.39（1.98）和 4.47（2.82），拉伸组 6.83（1.42）和 4.24（2.43），激光组 6.61（1.68）和 2.94（2.65），对照组 6.74（1.75）和 6.47（2.29）。治疗前后的残疾评分（ = 0.000237）分别为：激光+拉伸组 12.36（5.02）和 8.08（4.64），安慰剂+拉伸组 12.71（5.12）和 9.90（4.95），拉伸组 11.83（2.77）和 7.20（5.28），激光组 11.58（5.59）和 8.21（6.18），对照组 11.23（4.68）和 11.45（4.83）。
激光治疗联合拉伸运动可改善膝骨关节炎患者休息时、日常生活活动时、关节僵硬时、肌肉缩短和关节活动度的疼痛。
