About

To evaluate and compare the effects of Neuromuscular Electrical Stimulation when applied in the agonist and antagonist muscles of spastic hemiparetic patients.

The specific objectives are:

• Evaluate the resistance movement, strength and muscle electrical activity before and after application of Neuromuscular Electrical Stimulation in spastic muscle (gastrocnemius).
• Evaluate the resistance movement, strength and muscle electrical activity before and after application of Neuromuscular Electrical Stimulation in the spastic antagonist muscle (tibialis anterior).
• Compare the risk of falls after application of Neuromuscular Electrical Stimulation in both muscles studied.

Full description

Most hemiparetic patients can develop spasticity, characterized by neuronal hyperexcitability, increased resistance to passive stretch, Babinski sign, clonus, reflexes and involuntary spasms skin.

As a consequence, there may be contractures and muscle shortening, generating functional limitations. Neuromuscular Electrical Stimulation feature that can control the spasticity through reciprocal inhibition, muscle relaxation and sensory stimulation. The goal will be to evaluate and compare the effects of neuromuscular electrical stimulation when applied in the agonist and antagonist muscles of spastic hemiparetic patients.

Enrollment: 15 estimated patients

Sex: All

Ages: 45 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• involve patients who have spasticity grade 1, 1 + and 2 of the gastrocnemius muscle, which ambulate with or without assistance devices, patients who tolerate the stimulus and have preserved cognition.

Exclusion criteria

• involve patients who have severe shortening, joint stiffness, cognitive deficits and patients with hypersensitivity.

15 participants in 1 patient group

Group 1 (G1) NMES is applied in the spastic antagonist muscle

Experimental group

Description:

The parameters considered for the application of NMES are: frequency of 50Hz, the wavelength of 350m / s, 10 seconds of contraction of 20 seconds of rest to total 15 minutes. During the application of NMES patients will be positioned supine on the bed with knees flexed semi supported on roller positioning. The G1 apply NMES on the motor point of the tibialis anterior and triceps surae lengthening held along with the contraction (reciprocal inhibition).

Treatment:

Other: Group 2 (G2) NMES is applied in the spastic muscle (gastrocnemius).
