Background: According to world health organization globally 15% of populations are disabled and in Bangladesh 10% are disabled and among them, 42% child has a disability related to CP. The study purpose was to explore the effectiveness of rebound therapy along with conventional physiotherapy for muscle tone management in children with Cerebral palsy (CP). Methodology: Study used Randomized control trial (RCT) at CRP pediatric department at Dhaka Bangladesh. Results: Statistical analysis was done by using Mann Whitney “U” test. Where in experimental group, mean difference of muscle tone at the following of quadriceps femoris (Right), quadriceps femoris (Left), Hamstrings (Right), Hamstrings (Left), Gastrocnemius (Right), Gastrocnemius (Left), Biceps brachi (Right), Biceps brachi (Left), Wrist flexors (Right) and Wrist flexors (Left) was 1, 1, 1.5, 1.4, 1.9, 1.9, 0.5, 0.7, 0.3 and 0.5 more than control group. Pre-test and post-test score ensure rebound therapy more significant for the management of lower limbs muscle tone than upper limbs. Significant improvement wasn’t found (p>0.05). So improvement was not statistically significant. According to mean difference study has found greater improvement in the experimental group by applying rebound therapy to CP child. Conclusion: This true experimental study concludes that rebound therapy with conventional physiotherapy is more effective than only conventional physiotherapy.
