Summary

Introduction

Hypertonia is prevalent in anti-gravity muscles, such as the biceps brachii. Neural mobilization is one of the techniques currently used to reduce spasticity.

Objective

The aim of the present study was to assess electromyographic (EMG) activity in spastic biceps brachii muscles before and after neural mobilization of the upper limb contralateral to the hemiplegia.

Materials and Methods

Repeated pre-test and post-test EMG measurements were performed on six stroke victims with grade 1 or 2 spasticity (Modified Ashworth Scale). The Upper Limb Neurodynamic Test (ULNT1) was the mobilization technique employed.

Results

After neural mobilization contralateral to the lesion, electromyographic activity in the biceps brachii decreased by 17%and 11%for 90掳 flexion and complete extension of the elbow, respectively. However, the results were not statistically significant (p gt; 0.05).

Conclusions

When performed using contralateral techniques, neural mobilization alters the electrical signal of spastic muscles.
