CONTEXT
Cervical spondylosis (CS) is a very common, age-related, chronic, disc-degeneration condition. Alternative medicine has been widely used to treat neck pain in CS. However, no randomized controlled trials have focused on the effects and safety of percutaneous neuromuscular electrical stimulation (PNMES) for neck-pain relief in patients with CS.
OBJECTIVE
The study aimed to evaluate the effects and safety of PNMES for treating neck pain in patients with cervical spondylosis (CS).
DESIGN
The research team designed a two-arm, double-blinded, randomized, sham-controlled trial.
SETTING
The study was conducted at the People's Hospital of Yan'an in Yan'an, China.
PARTICIPANTS
Participants were 124 patients with neck pain from CS at the hospital.
INTERVENTION
Participants were randomly divided into an intervention group and a control group in a ratio of 1:1. The intervention group received PNMES (PNMES group), and the control group received sham PNMES for 30 minutes daily 3 times weekly, for 12 weeks.
OUTCOME MEASURES
The outcome measures included: (1) a visual analog scale (VAS), (2) a test of cervical range of motion (ROM), and (3) the neck disability index (NDI) score. All outcome measurements were measured immediately postintervention and in a follow-up at 4 weeks postintervention. In addition, AEs were also recorded duration the period of treatment.
RESULTS
Immediately postintervention and at the follow-up, the PNMES group exhibited decreases in the mean VAS (P < .01) and NDI score (P < .01) that were significantly greater than those of the control group. Additionally, the increase in the mean ROM was significantly higher in the PNMES group than that in the control group, both immediately postintervention and at the follow-up (P < .01). No AEs were found in either group.
CONCLUSIONS
The results of this study have demonstrated that PNMES is more effective than sham PNMES for neck-pain relief in patients with CS.
背景
颈椎病（CS）是一种非常常见的、与年龄相关的、慢性的椎间盘退变疾病。替代医学已被广泛用于治疗 CS 引起的颈部疼痛。然而，目前还没有随机对照试验专门关注经皮神经肌肉电刺激（PNMES）治疗 CS 患者颈部疼痛的效果和安全性。
目的
本研究旨在评估 PNMES 治疗 CS 患者颈部疼痛的效果和安全性。
设计
研究团队设计了一项双臂、双盲、随机、假对照试验。
设置
该研究在中国延安的延安市人民医院进行。
参与者
医院的 124 名患有 CS 引起的颈部疼痛的患者参加了这项研究。
干预
参与者按照 1:1 的比例随机分为干预组和对照组。干预组接受 PNMES（PNMES 组），对照组接受假 PNMES，每天 30 分钟，每周 3 次，共 12 周。
结局测量
结局测量包括：（1）视觉模拟量表（VAS），（2）颈椎活动范围（ROM）测试，和（3）颈部残疾指数（NDI）评分。所有结局测量均在干预后即刻和干预后 4 周的随访时进行。此外，还记录了治疗期间的不良事件（AE）。
结果
干预后即刻和随访时，PNMES 组的平均 VAS（P<0.01）和 NDI 评分（P<0.01）均显著下降，且明显优于对照组。此外，PNMES 组的平均 ROM 增加幅度在干预后即刻和随访时均显著高于对照组（P<0.01）。两组均未发现不良事件。
结论
本研究结果表明，PNMES 缓解 CS 患者颈部疼痛的效果优于假 PNMES。
