Abstract

OBJECTIVES: The proposal of the present study is based on mobilizing the nervous system of the upper hemiplegic limb of stroke victims using the Upper Limb Neurodynamic Test (ULNT 1) and electromyographic analysis of the biceps brachii muscle. METHODS: A pre-experimental study was carried out with pretest and posttest repeated measurements on five stroke victims (4 men and 1 woman; mean age: 52.8 +/- 11 years), with Grade 1 and + 1 spasticity, according to the modified Ashworth scale. Electromyographic analysis of the biceps brachii muscle was performed with the elbow flexed at 90 degrees, following by complete extension. RESULTS: The neurodynamic test led to a decrease in electromyographic activity in the biceps brachii muscle (p < or = 0.05). CONCLUSION: Neural mobilization was efficient in reducing myoelectric activity in the biceps brachii muscle in patients with stroke and may used by physiotherapists as an efficient method for treating patients with this pathology.
