This case study examines the outcomes of a 9-year-old male who received applied functional science movement based therapy following a 12-week arm cast for a distal radius/ulna fracture. The patient received 6 weeks of therapy focused on restoring range of motion, strength, and function through a progressive 3-phase protocol. Evaluation measures showed significant improvements in range of motion, grip strength, muscle strength, and disability scores. While grip strength improved substantially, it did not fully return to normal levels. The functional movement based approach effectively reduced impairments and disability from immobilization.
