Effect of Transcranial Electromagnetic Stimulation on Modulation of Wrist Flexors Spasticity in Stroke Patients

Abstract

Purpose: To determine the effect of rhythmical transcranial low frequency electromagnetic stimulation on wrist flexors spasticity and hand function in Stroke patients. Subjects: 30 Stroke patients of ages ranged from 50 to 77 years with mean age of (56.±6.6) years were randomly participated and divided into two equal groups of 15. Method: Group I received a designed program of physical therapy, as control group. Group II received the same designed program of physical therapy of group 1 in addition to transcranial low frequency electromagnetic stimulation as study group. Both groups were clinically assessed through Modified Ashworth Scale for degree of wrist flexor spasticity, Digital goniometer for wrist flexion and extension range of movement, and assessed electrophysiolgically for activity of flexor carpi radialis longus and hand functions through Purdue pegboard device before and after treatment program. Results: There was statistical significant difference between both groups with GII best results, regarding to clinical and electrophysiological parameters. Conclusion: Low frequency transcranial electromagnetic stimulation is considered more effective in rehabilitating wrist flexors spasticity and hand functions in Stroke patients.
