---|---|
Positioning | Proper positioning is important for stability when sitting, lying or standing. Can also isolate specific muscles during exercise. |
Stability | Ability of joints to maintain their integrity. Affects Balance |
Balance | Depends on base of support, centre of mass, line of gravity |
Base of Support | Region bounded by the body parts in contact with a supporting surface. |
Centre of Mass | Imaginary point in the body where all weight or mass seems to be centred. Usually located within the pelvic region in the anatomical position. |
Line of Gravity | Imaginary vertical line passing through the centre of mass and the supporting surface. |
Maintain Stability | Line of gravity of the entire body must remain within the base of support. If one segment moves forward another must move back to compensate. |
Promote Stability 1 | Increase size or area of base of support |
Stability 2 | Decrease height over centre of mass |
Stability 3 | Direct line of gravity over base of support |
Stability 4 | Keep movements slow and controlled |
