Abstract

Purpose/Aim

The aim of this study was to determine the acute effects of IASTM on cervical joint position error and pain in individuals with chronic neck pain.

Methods

A total of 39 individuals with chronic neck pain were included in this study. Participants were randomized into three groups: Instrument-assisted soft-tissue mobilization(IASTM (n = 13), sham (n = 13), and control (n = 13). In the IASTM group, intervention was applied to the sternocleidomastoid and trapezius muscles with an application time of 45 s and a frequency of 60 beats/min. In the sham group, IASTM was applied at a 90° angle without pressure. The control group did not receive any intervention. The pain severity and joint position error(JPE) were evaluated before and after the intervention, by using the visual analogue scale and a cervical range of motion device.

Results

The effects of time and treatment group on visual analogue scale(VAS) score were statistically significant (p = .001). Instrument-assisted soft-tissue mobilization was more effective in VAS score than sham and control group (p < .001). Significant improvement was found in JPE in all range of motions of the cervical region in the instrument-assisted soft-tissue mobilization group (p < .05). In the sham group, significant improvements were observed in cervical extension, left rotation, and left lateral flexion movements in JPE during each cervical spine active movement (p < .05). Instrument-assisted soft-tissue mobilization group was more effective in JPE all directions than sham and control group.

Conclusions

Instrument-assisted soft-tissue mobilization may be a useful technique in individuals with chronic neck pain. Instrument-assisted soft-tissue mobilization decreases VAS and improves JPE.

器械辅助软组织松动技术对慢性颈痛患者疼痛和关节位置错误的急性影响：一项双盲、随机对照试验

摘要

目的/目标

本研究的目的是确定 IASTM 对慢性颈痛患者颈椎关节位置错误和疼痛的急性影响。

方法

本研究共包括 39 名慢性颈部疼痛患者。参与者被随机分为三组：仪器辅助软组织动员（IASTM（n = 13），假手术（n = 13）和对照组（n = 13）。在 IASTM 组中，对胸锁乳突肌和斜方肌进行干预肌肉施加时间为45 s，频率为60次/分钟。在假手术组中，IASTM以90°角无压力施加。对照组不接受任何干预。疼痛严重程度和关节位置误差（ JPE) 在干预前后进行了评估，使用视觉模拟量表和颈椎活动范围装置。

结果

时间和治疗组对视觉模拟量表 (VAS) 评分的影响具有统计学意义 (p = .001)。仪器辅助软组织动员在 VAS 评分方面比假手术组和对照组更有效 (p < .001)。在器械辅助软组织动员组中，JPE 在颈部区域所有运动范围内均有显着改善 (p < .05)。在假手术组中，在每次颈椎主动运动期间，在 JPE 中观察到颈椎伸展、左旋和左侧屈运动有显着改善 (p < .05)。器械辅助软组织动员组在各个方向的 JPE 比假手术组和对照组更有效。

结论

器械辅助软组织松动术可能对慢性颈部疼痛患者有用。器械辅助软组织动员可降低 VAS 并改善 JPE。
