Abstract:-
BACKGROUND: Stroke is a condition in which Spasticity in the body musculature greatly affect the functional independence of the patients. Transcutaneous Electrical Nerve Stimulation (TENS) is one of the useful modality to reduce Spasticity.
OBJECTIVE: The purpose of this study was to investigate the effectiveness of Transcutaneous Electrical Nerve Stimulation over Gastrocnemius muscle spasticity among hemiparetic patients.
STUDY DESIGN: Quasi-experimental study design, pre and post type.
PROCEDURE: Ten subjects were randomly allocated into two groups (Group A and Group B). For 5 subjects in Group A, conventional therapy was given (Passive stretching and Passive range of motion). For other 5 subjects in Group B, Transcutaneous electrical nerve stimulation was applied over belly of Gastrocnemius muscle for 60 minutes at 100 Hz frequency, 200 microseconds of pulse width with 2 or 3 times sensory threshold along with conventional therapy was given. Modified Ashworth Scale was measured before and after the treatment.
RESULTS: The TENS group showed a significant reduction in spasticity of Gastrocnemius, compared to the conventional group (p<0.05).
CONCLUSION: On the basis of this study, it shows that application of TENS over Gastrocnemius, can reduce the muscle spasticity in stroke patients.

Key Words: Stroke, Spasticity, Transcutaneous electrical nerve stimulation (TENS), Modified Ashworth Scale. (MAS).

I. INTRODUCTION

Stroke is caused by the interruption of the blood supply to the brain, usually due to a blood vessel bursts or is blocked by a clot. A stroke is very similar to a heart attack, only in this case, blood flow to brain is blocked, rather than heart. Damage is occurred to the brain tissue, due to lack of blood supply of oxygen and nutrients to the brain, resulting in cerebrovascular accident.
