PURPOSE: This case report assesses the outcomes of a 6-week modified intensive program for a 4-year-old boy with cerebral palsy (CP), Gross Motor Function Classification System Level IV. SUMMARY OF KEY POINTS: The modified intensive program included the practice of developmental gross motor skills, standing/gait training in adaptive equipment, constraint-induced movement therapy, and whole body vibration. CONCLUSIONS: The child improved in 4 of the 5 outcomes, including timed sitting balance and modified versions of the 5 Times Sit-to-Stand Test and 9-Hole Peg Test. His ability to assist with transfers, sit independently, and use both hands for play and self-help skills also improved. RECOMMENDATIONS FOR CLINICAL PRACTICE: This case report adds to the body of evidence supporting the use of intensive program models of physical therapy for children with CP and highlights the need for additional research in this emerging area of clinical practice.
