Effect of Electrical Stimulation on improvment of the movement ability in children with Spastic Cerebral Palsy

INTERVENTION: Intervention1: Electrical stimulation along with conventional physiotherapy/occupational therapy: Schedule â?? 30 min. physiotherapy plus 30 min of Electrical Stimulation each day for 5 days per weeks for 12 weeks period at a strech. Control Intervention1: Conventional Physiotherapy/occupational therapy only: Schedule â?? 60 min(30 min + 30 min) conventional physiotherapy each day for 5 days per weeks for 12 weeks period at a strech CONDITION: Spastic Cerebral Palsy (Hemiplegic/ Diplegic) PRIMARY OUTCOME: 1. Quantitative Gait Analysis. Parameters to be measured Gait Speed, Cadence, Step Length etc. ; 2. sEMG changes of Tibialis Anterior in time‐frequency domain. ; 3. EEG changes in time‐frequency domain.‐‐‐‐‐‐Timepoint: All measurement taken at ; Baseline (Pre‐treatment ), and after 4, 8, and 12 weeks at the end of intervention SECONDARY OUTCOME: 1. Energy expenditure through physiological cost index(PCI), ; 2. Functional improvement measured using a standard Gross Motor Function Measure‐GMFM 66 scale) ; 3. Questionnaire about impression of the interventions, complaints, ability to dorsiflex ankle and any effect on their walking.‐‐‐‐‐‐Timepoint: All measurement taken at ; Baseline (Pre‐treatment ), and after 4, 8, and 12 weeks at the end of intervention INCLUSION CRITERIA: 1.Spastic diplegic or spastic hemiplegic cerebral palsy. 2. Controlled or seizure free. 3. MAS score of equal to or less than 2; 4. GMFCS level less than level IV. 5. A minimum of 6 months gap post botulinum toxin injections. 6. Minimum 1 year after a bone or a soft tissue surgery. 7. Children cooperative and tolerant to machine and intervention. 8. Parents motivated and willing.
