Occupational and daily activities
Lifting tasks
Head, trunk, pelvis are maintained in midline alignment throughout the activity Cocontraction of anterior and posterior muscles
• the joint motion with the distal segment moves free in space, e.g. raising lower leg or throwing a ball
closed kinematic chain motion 闭链运动 • the joint motion with the distal segment is fixed, e.g. standing up or squatting down
Mobility
Floor mobility:rolling
Rolling Developmental direction:
nonsegmental ---segmental Supine to prone
more individual variation more difficult than prone to supine
