Purpose: The reason for doing this study was to see how action-observation physical training affected the quality of upper limb functions and functional independence among children who have hemiplegic cerebral palsy (HCP). Subjects and Methods:  Thirty children who have a diagnosis of HCP, aged 6-9 years, have been randomized into 2 groups: the control group got a routinely chosen physiotherapy program, whereas the examined group got action observation physical training (AOPT) on the upper limb besides a standard selected physiotherapy program for three successive months. Children who have cerebral palsy (CP) underwent the Quality of Upper Extremity Skills Test (QUEST) in order to determine the level of quality of their upper limbs' functions, including their movement patterns and hand functions, while the Wee Functional Independence Measure (Wee FIM) was utilized to assess their functional independence. Results: According to statistical analysis, there had been no substantial variance between the two groups prior to therapy. After treatment, the examined group''s four QUEST domains (dissociated movement, weight-bearing, grasp, and protective reaction) and WEE FIM significantly improved (P = 0.0001) when contrasted with the control group. Conclusions: The addition of action observation physical training to physical therapy resulted in better, more effective and significant results on upper limb functional abilities in HCP children.
