Phase N/A Results N/A

Trial Description

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.

Conditions

Interventions

  • Group 2 (G2) NMES is applied in the spastic muscle (gastrocnemius). Other
    Intervention Desc: 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.
    ARM 1: Kind: Experimental
    Label: Group 1 (G1) NMES is applied in the spastic antagonist muscle
    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).
