Abstract
Background. Studying of robotic-assisted locomotor training (lokomat) in spasticity modulation on cerebral palsied hemiplegic children is a strategy for determining its efficacy in reducing spasticity.
Objective. To investigate the efficacy of robotic-assisted locomotor training (lokomat) in spasticity modulation. Methods. Thirty spastic hemiplegic cerebral palsied children of both genders ranged in age from 7 to 14 years contributed in this study, they were being randomly selected from comprehensive rehabilitation center and assigned into two equal groups (15 children each). Control group (A) underwent traditional exercise treatment, while Study group (B) underwent lokomat gait training in addition to traditional exercise program. Lokomat training was performed 3 days/week for 4 weeks with up to 45 minutes of training per session. The 3-D kinematics gait analysis was carried out before and after intervention and used as an indicator for improvement and reduction of spasticity.
Results. there was a statistically significant improvement in the study group in comparison to control group. Conclusion. Lokomat gait training is an effective additional tool for physical therapy program in treatment of hemiparetic C.P. children as it plays an important role in decreasing spasticity and improving patient gait pattern.
