Effects of an Intervention Program by Proprioceptive Neuromuscular Facilitation, in Muscle Force Irradiation.

Electromyography Evaluation of the Stabilizing Muscles of the Scapula and Tibial Anterior Muscle, After an Intervention Program by Proprioceptive Neuromuscular Facilitation in Muscle Force Irradiation.

The present study aims to assess through surface electromyography, the effectiveness of proprioceptive neuromuscular facilitation protocols in the activation of the stabilizing muscles of the scapula and the anterior tibial muscle.

Study Overview

• Status: Unknown
• Conditions: Assessment of Muscle Force Irradiation
• Intervention / Treatment: Other: Proprioceptive Neuromuscular Facilitation - PNF

Detailed Description

Healthy subjects and subjects with demyelinating polyneuropathy are involved in the study.

Healthy patients are arranged in two groups of stimulation: FNP Group (intervention proprioceptive neuromuscular facilitation) - CC Group (intervention classic cinesioterapia). The electromyographic response of the stabilizing muscles of the scapula of each individual will be assessed prior to application of the protocols, during the execution of the protocols and immediately after stopping in a single session.

Patients with demyelinating polyneuropathy are arranged in a single treatment group and will be treated at a frequency of twice a week for five weeks. In each session, the PNF patterns will be repeated four times, on both sides, stimulating muscle irradiation and evoking the contraction of the tibialis anterior muscle. During the repetition of the patterns, the dorsiflexor muscle response of each patient will be obtained by an electromyography (EMG) surface.

The data of the RMS values obtained in the first session will be normalized and transformed into percentage. The average RMS of each diagonal at the beginning of treatment corresponds to 100% of TA muscle activation. The RMS values obtained in the last session will be normalized as a percentage, taking into account the results of the first evaluation. After normalization, data from the first and last sessions will besubjected to the for paired t-test.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluation of muscle force irradiation, through surface electromyography.	Irradiation of muscle strength will be assessed using surface electromyography, which shows the activation or not of the muscles evaluated.	This evaluation of patients is performed in only one day, being made before, during and after the application of the protocols. It is estimated that the results are collected in one years.
