Effect of Low Level Laser Therapy on Hamstring Muscle Tightness and Calf Muscle Spasticity in Cerebral Palsy Children.

Background :Spasticity is a motor disorder in children with cerebral palsy (CP) Cp is a non progress lesion in unmature brain lead to a group of chronic disorders that affect movement and posture development, may be accompanied by epilepsy, secondary musculoskeletal problems, deformaties and disturbances of sensation, perception, cognition, communication, and behavior Few studies demonstrate effectiveness of laser therapies in spasticity in cp.

Methodology : This study is randomize control trail aimes to evaluate the effect of low-level laser therapy (LLLT) on the spasticity of hamstring and calf muscle in children with CP over 12 session of intermittent laser exposures. Muscle tone , gross motor function, rang of motion (rom ) and poplital angle will evaluate before and after laser irradiation in 30 children with CP both geneder aged between two to six years old diaplegic clidren , exclusion children who take botox or done surgery . Muscles will irradiated with low-intensity diode laser pulses of 808-nm wavelength three times per week over one month follow up for one month.
