An interventional study of Group 2 (G2) NMES is applied in the spastic muscle (gastrocnemius). in Cerebrovascular Accident, sponsored by Universidade do Vale do Paraíba. Status unknown at 1 site in Brazil. Open to participants aged 45 Years to 75 Years. Per ClinicalTrials.gov, last updated 2013-09-18.

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:
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.
7,441 studies on the registry are indexed under Stroke; 2,012 are open to participants now.
This study's planned enrollment of 15 is below the median of 50 across 5,482 interventional studies indexed under Stroke.

Exclusion Criteria:
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).
Other: Group 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.
