To compare the effects of biofeedback with those of active exercise and passive treatment in treating work-related neck and shoulder pain.
A randomized controlled trial with 3 intervention groups and a control group.
Participants were recruited from outpatient physiotherapy clinics and a local hospital.
All participants reported consistent neck and shoulder pain related to computer use for more than 3 months in the past year and no severe trauma or serious pathology. A total of 72 potential participants were recruited initially, of whom a smaller group of individuals (n=60) completed the randomized controlled trial.
The 3 interventions were applied for 6 weeks. In the biofeedback group, participants were instructed to use a biofeedback machine on the bilateral upper trapezius (UT) muscles daily while performing computer work. Participants in the exercise group performed a standardized exercise program daily on their own. In the passive treatment group, interferential therapy and hot packs were applied to the participants' necks and shoulders. The control group was given an education booklet on office ergonomics.
Pain (visual analog scale), neck disability index (NDI), and surface electromyography were assessed preintervention and postintervention. Pain and NDI were reassessed after 6 months.
Postintervention, average pain and NDI scores were reduced significantly more in the biofeedback group than in the other 3 groups, and this was maintained at 6 months. Cervical erector spinae muscle activity showed significant reductions postintervention in the biofeedback group, and there were consistent trends of reductions in the UT muscle activity.
Six weeks of biofeedback training produced more favorable outcomes in reducing pain and improving muscle activation of neck muscles in patients with work-related neck and shoulder pain.
比较生物反馈与主动运动和被动治疗在治疗与工作相关的颈肩部疼痛中的效果。
一项随机对照试验，分为 3 个干预组和 1 个对照组。
参与者从门诊物理治疗诊所和当地医院招募。
所有参与者报告在过去一年中因使用计算机而持续出现颈肩部疼痛，且无严重创伤或严重病理。最初招募了 72 名潜在参与者，其中一小部分（n=60）完成了随机对照试验。
3 种干预措施均应用 6 周。在生物反馈组中，参与者被指导在使用计算机时每天在双侧上斜方肌（UT）上使用生物反馈机。运动组的参与者自行每天进行标准化运动。在被动治疗组中，对参与者的颈部和肩部进行干扰电疗和热敷。对照组给予有关办公人体工程学的教育手册。
疼痛（视觉模拟评分）、颈部残疾指数（NDI）和表面肌电图在干预前和干预后进行评估。疼痛和 NDI 在 6 个月后再次评估。
干预后，生物反馈组的平均疼痛和 NDI 评分明显低于其他 3 组，且在 6 个月时仍保持较低水平。生物反馈组颈椎伸肌的肌肉活动在干预后显著减少，UT 肌肉的活动也呈现出持续减少的趋势。
6 周的生物反馈训练在减轻与工作相关的颈肩部疼痛和改善颈部肌肉肌肉激活方面产生了更有利的结果。
