Brief summary

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.

Detailed 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.

Interventions

OTHERGroup 2 (G2) NMES is applied in the spastic muscle (gastrocnemius).

The G2 apply NMES in the gastrocnemius motor point and the rest will be done during stretching of the gastrocnemius muscle (autogenic inhibition). Five consecutive sessions will be held in the morning and afternoon in the laboratory of Sensory Motor Rehabilitation Engineering.

Analysis of the electrical muscle activity and resistance to movement after application of neuromuscular electrical stimulation (NMES) in patients with spastic hemiparesis.	12 months	The G1 apply Neuromuscular Electrical Stimulation on the motor point of the tibialis anterior and triceps surae lengthening held along with the contraction (reciprocal inhibition). The G2 apply electrical muscle activity and resistance to movement after application of neuromuscular electrical stimulation (NMES) in patients with spastic hemiparesis.
