Background and Aim: The role of function of upper extremity in activity of daily living is critical and any impairment of function could cause major problems for diplegic spastic cerebral palsy (CP) patients. So, the application of rehabilitation protocols that could regain the hand function is very important.

The purpose of this study was to explore the effects of simultaneous activation of exteroception and proprioception on function of upper extremity in children with diplegic spastic CP, 3-7 years old.

Materials and Methods: Thirteen CP patients (3-7 years mean: 4.92 years 4 boys and 9 girls) were participated in this study. Simultaneous activation of exteroception and proprioception were done 3 times a week (for 8 weeks). Function of upper extremity was evaluated by Quest Test and the degree of spasticity in wrist was evaluated by Modified Ashworth Scale.

 Results: The results of this study showed that after simultaneous activation of exteroception and proprioception, function of upper extremity was significantly improved (P<0.001). In addition, degree of spasticity in wrist muscles was significantly decreased (P<0.022).

Conclusion: Based on results of current study, it might be suggested that simultaneous activation of exteroception and proprioception could improve the function of upper extremity and decrease of spasticity. This in respect could reduce the disabilities of patients. So, the application of current protocols for the patients is suggested.
