激痛点干针疗法用于老年慢性腰痛患者的临床疗效观察

Clinical Curative Effect of Trigger Point Dry Needling on Chronic Low Back Pain in Elderly Patients

目的评价激痛点干针治疗老年慢性腰痛患者的临床疗效和不良反应。方法 60例老年慢性腰臀部肌筋膜疼痛患者被随机分配到干针组和对照组。干针组30例患者在腰臀部肌筋膜激痛点上接受干针治疗,而对照组30例患者在腰臀部疼痛部位接受低强度感觉闭经皮电刺激安慰性对照治疗。2组各接受每周2次,共4周的治疗。2组患者分别在治疗前、后进行临床评估,内容包括主观疼痛(VAS)和功能障碍(RDQ)水平以及腰部活动范围(ROM)测量。结果干针组在治疗后疼痛、功能障碍和活动范围均显示了显著改善,而对照组虽仅在治疗后即刻有疼痛和功能障碍的显著改善,但2组间比较仍显示干针组疗效优于对照组。除了干针后酸痛反应,没有观察到其他不良反应。结论激痛点干针对于改善老年慢性腰痛患者的疼痛症状和功能性表现均有积极的治疗作用,可能是治疗老年慢性腰痛的一种有效方法。

Objective To discuss the clinical curative effect of trigger point dry needling on chronic low back pain in elderly patients and the side effect. Methods 60 elderly patients with chronic myofascial pain of the waist and buttock were randomly divided into 2 groups： dry needling group （n=30） and control group （n=30）, dry needling at myofascial trigger point of the waist and buttock was applied to patients in dry needling group while transcutaneous electrical stimulation with low- intensity sensory threshold was applied as placebo treatment to patients in control group, the treatment for each group was per-formed twice a week and the course lasted for 4 weeks, clinical evaluation was made before and after treatment in the 2 groups, including the scores of VAS, the level of RDQ and the measurement of ROM. Results After treatment, an obvious improvement in pain, function disorder and motion range was found in patients in dry needling group while only an impro-vement in pain and function disorder immediately after treatment was found in patients in control group, the curative effect in dry needling group was superior to that in control group; no other side effects were found except for aching pain after dry ne-edling treatment. Conclusions Trigger point dry needling is of positive effect in improving the pain symptoms and function performance, which may be an effective treatment for the elderly patients with chronic low back pain.
