Large upper body

- Shape up in Prio 3A


A large upper body that is poorly supported can result in trunk flexion and respiratory difficulties. Evaluate both the active and resting positions carefully.
It is beneficial to adjust the lumbar angle to increase the angle at the lumbar adjustment to make space for the upper body, this will help to open the thoracic spine to ease respiration.

If the 3A lumbar angle is adjusted to a greater angle, then this could affect the stability of an individual with the large upper body so it is important to consider using the clips to limit the tilt.
