To find out functional strength training exercise on improving gross motor function among the children with spastic hemiplegic cerebral palsy children. Single group pre-experimental research design. The most common cause of movement disability in infancy is cerebral palsy. Cerebral palsy patients have impairments such as spasticity, low muscle strength and selective motor control in their body function. Such deficiencies may limit activity performance and participation in everyday life. Improving and optimising activities and involvement are crucial treatment objectives. Functional strength workouts are vital to overcoming obstacles to improving the functionality of children with neurological issues. 92 subjects of spastic hemiplegic cerebral palsied aged 4-8, male and female with spastic hemiplegic cerebral palsy were selected under purposive sampling technique and received functional strength training exercise for a period of ten weeks. To assess the gross motor function (functional independence) pre and post the exercise program, Gross motor functional measure was used. Results: The pre and post measurements shows significant changes in the gross motor function among children with spastic hemiplegic cerebral palsy. The results of the post-test mean values show improvement in gross motor functions after functional strength training program (p<0.05). The functional strength training program proves that increased gross motor function and thereby improvement in functional abilities among children with spastic hemiplegic cerebral palsy after ten weeks of intervention.
