Study investigated the efficacy of combined passive stretching and active movement training with motivating games delivered by a rehabilitative robot to increase lower limb motor control and range of motion (ROM) in children with cerebral palsy (CP). Participants were 12 children, 6 girls and 6 boys, aged 5 to 16 years with mild to moderate spastic CP and impaired ankle function. A portable rehabilitation robot with computer game interface was used to deliver the designated protocol and to measure the biomechanical data. The robot was equipped with a torque sensor, a servomotor, and a digital controller and was connected to a personal computer for display and as a user interface. The 3 times per week, 6 week intervention consisted of 20 minutes of passive stretching followed by 30 minutes of active movement training and ended with 10 minutes of passive stretching. Each participant was seated in a comfortable chair fixed to the floor with the robot in front of him or her at a distance that kept the knee extended. Passive ROM (PROM), active ROM (AROM), dorsiflexor and plantarflexor muscle strength, Selective Control Assessment of the Lower Extremity, and functional outcome measures were evaluated before and after intervention. Significant increases were observed in dorsiflexion PROM, AROM, and dorsiflexor muscle strength. Spasticity of the ankle musculature was significantly reduced. Selective motor control improved significantly. Functionally, participants showed significantly improved balance and increased walking distance within 6 minutes. Study limitations and implications for future research are discussed.
