Abstract:
BACKGROUND:Foot position and seat height are important factors affecting "Sit-to-Stand",but most of the current research on "Sit-to-Stand" focuses on healthy people and Parkinson's disease patients. The kinematic and kinetic characteristics of the lower limbs of children with spastic cerebral palsy during the "Sit-to-Stand" task under different foot positions and seat heights are not known.OBJECTIVE:To investigate the effects of different foot positions and different seat height on lower limb kinematic and kinetic parameters during the "Sit-to-Stand" task in children with cerebral palsy. METHODS:Seven children with spastic cerebral palsy were selected as the research subjects. All subjects received the "Sit-to-Stand" test of six tasks,namely three seat heights (high,medium,and low stools) × two foot positions (front and back foot positions). The kinematic and dynamic data of children with cerebral palsy were collected under different foot positions and seat heights.RESULTS AND CONCLUSION:(1) The time characteristics results showed that the total time required for the children with cerebral palsy to perform the sit-to-stand transfer task was significantly smaller in the high stool condition compared to the low stool condition (P=0.046). (2) The kinetic results showed that at the moment of lifting,the knee flexion moment was significantly larger in the bipedal posterior condition than the bipedal anterior condition (P=0.049). The knee flexion moment was significantly smaller in the high stool condition compared to the medium stool condition (P<0.001). (3) It is concluded that raising the seat height and changing the foot position had an effect on the sit-to-stand transfer in children with spastic cerebral palsy. The children were able to perform the sit-to-stand maneuver with less motor compensation in the high-stool bipedal-rear position condition. Meanwhile,the high chair can be used as an aid to enhance the performance of sit-to-stand transfer in children with spastic cerebral palsy. The high stool bipedal hindfoot condition was the most effective in improving the sit-to-stand transfer in children with spastic cerebral palsy.
