Abstract

Purpose

The main objective was to compare the effects of neural mobilization (NM), NM performed through mirror therapy (MT), NM performed through action observation (AO) training and finally classic rehabilitation program (mobility and strength) exercises on neural mechanosensitivity, widespread of proximal and distal pain and pressure pain thresholds (PPT). The second objective was to assess the effects of these interventions on handgrip strength, conditioned pain modulation, motor imagery ability and temporal summation.

Materials and methods

Single-blinded randomized controlled trial. Fifty-four healthy subjects were randomly assigned to each group. Neural mechanosensitivity, widespread pain and PPT were the main variables. The secondary variables included handgrip strength, conditioned pain modulation, motor imagery ability and temporal summation.

Results

All groups showed significant differences in time*factor for neural mechanosensitivity (p = 0.001), PPT in the dermatome of the median nerve (p = 0.007), PPT at carpal tunnel (p < 0.05) and proximal widespread (p = 0.01). No differences were found for distal widespread, conditioned pain modulation, handgrip strength motor imagery ability or temporal summation (p > 0.05). There is an absence of statistically significant differences between groups.

Conclusions

NM through movement representation techniques can reduce mechanosensitivity and mechanical hyperalgesia in the median nerve dermatome and forearm, although no differences were found between groups.

通过运动表征技术进行神经动员对改善正中神经区域神经机械敏感性的影响：一项随机对照试验

摘要

目的

主要目的是比较神经动员 (NM)、通过镜像疗法 (MT) 执行的 NM、通过动作观察 (AO) 训练执行的 NM 以及最终的经典康复计划（灵活性和力量）练习对神经机械敏感性的影响，广泛的近端和远端疼痛和压力痛阈值 (PPT)。第二个目标是评估这些干预措施对握力、条件性疼痛调制、运动想象能力和时间总和的影响。

材料和方法

单盲随机对照试验。54 名健康受试者被随机分配到每组。神经机械敏感性、广泛疼痛和 PPT 是主要变量。次要变量包括握力、条件性疼痛调制、运动想象能力和时间总和。

结果

所有组在神经机械敏感性的时间*因素（p  = 0.001）、正中神经皮节的PPT（p  = 0.007）、腕管的PPT（p  < 0.05）和近端广泛（p  = 0.01）方面均显示出显着差异。在远端广泛的、条件性疼痛调制、握力运动想象能力或时间总和方面没有发现差异 ( p  > 0.05)。组间不存在统计学上的显着差异。

结论

NM 通过运动表征技术可以降低正中神经皮节和前臂的机械敏感性和机械痛觉过敏，尽管各组之间没有发现差异。
