The trunk control is essential for activity of daily living as well as the base that supports extremity motion. For example, supporting trunk muscles contract synergistically with arm motions (Angel and Eppler 1967; Dudel et al. 1996), or even with anticipation of the arm movement. This is often clear in patients with neurological problems. When the trunk is unstable, normal movement in the extremities is impossible. With the trunk able to move and stabilize effectively, patients gain improved control of their arms and legs (Davies 1995). The emphasis is on the trunk when the arms are joined by one hand gripping the other arm or when the legs are touching and move together.

摘要

The trunk control is essential for activity of daily living as well as the base that supports extremity motion. For example, supporting trunk muscles contract synergistically with arm motions (Angel and Eppler 1967; Dudel et al. 1996), or even with anticipation of the arm movement. This is often clear in patients with neurological problems. When the trunk is unstable, normal movement in the extremities is impossible. With the trunk able to move and stabilize effectively, patients gain improved control of their arms and legs (Davies 1995). The emphasis is on the trunk when the arms are joined by one hand gripping the other arm or when the legs are touching and move together.
