Aim: An electrical stimulation and passive stretching were used to reduce spasticity in spastic diplegic cerebral palsy children patient. Methodology: Intervention for four weeks which consisted of 30 minutes of electrical stimulation of antagonistic muscles and 30 seconds of passive stretching of the agonist muscles (bicep brachi) 3 times per week of spastic diplegic child patients. Pre and Post treatment Spasticity of the bicep brachi was measured using the modified Ashworth scale. Results: The mean value 1.43 of Group A post treatment was compared to the mean value 1.93 of Group B post treatment then the P value found to be 0.0057. Conclusions: Spasticity of diplegic cerebral palsy children are greatly reduced by using electrical stimulation combined with passive stretching. This suggests that electrical stimulation with passive stretching are more reliant to reduce spasticity than alone passive stretching.
