Understanding Negative Support Reactions in Physiotherapy

Negative Supporting Reaction

- Occurs when the force of gravity is greater than the supporting reaction.

- As the body is lowered towards the floor, the joint is required to work against the force of gravity to prevent collapse.

- This movement is useful for strengthening and proprioceptive training of both single and multi -joint muscles that are responsible for stabilization.

- If movement is too difficult, use more stable support surface; if too easy use a less stable surface.
