Introduction: Children with physical disabilities are less likely to access music and arts due to their extremity anomalies. “Budding Well” is a non-conventional rehabilitation program providing music and arts courses for the targeted participants. The program has run through the third year and a review of the service outcomes has been sorted. Materials and methods: Aged 6–18 years with different kinds and degrees of limb dysfunctions were invited to join the program. The course consisted of 10 learning classes on playing harmonica (music) or painting (arts). Functional assessments [Bruininks-Oseretsky-Test-of-Motor- Proficiency second edition (BOT-2) and Grip-and-pinch strength] and psychosocial centric questionnaires [Lyubomirsky and Lepper's Subjective Happiness Scale (SHS), Well-being Index (WHO-5), and Culture-free Self-esteem Inventory-2 (CFESI-2) Form A] were performed and completed at the first and last (10th) class. Program evaluation questionnaire was filled at the last class. Results: Thirty-five participants (male = 20, female = 15) of mean age 8.65 joined the program. Functional assessments and psychosocial centric questionnaire outcomes except CFESI-2 did not show any statistical difference. Age sensitivity testing in CFESI-2 Social domain score showed the best result when cut-off age was at 10.5 (p = 0.04) and this cut-off value was further proved by receiver operating characteristic (ROC) analysis (p < 0.01). On subjective evaluation, parents noticed a significant improvement in the hand function of their children (p= 0.01). Conclusion: Hand functions and psychosocial skills of children and teenagers with different levels of physical disabilities or disfigurement proved to benefit from our program through music and arts. Participants of age at 10.5 best responded to the program, particularly on the significant improvement in self-esteem.
