Your ligaments are the restraining bands that prevent joints from moving too far. Ligaments contain receptors that send signals to your brain, which allows you to know where your joint is in space.
Proprioception refers to the body’s ability to sense movement within joints and allows awareness of where your joints are in space.
A common example is when you sprain the outside ligament of your ankle, it heals with scar tissue. You can regain the range of movement of the joint, reduce the swelling and improve the strength. However, it is important to also re-train your joint awareness (proprioception) to prevent reoccurrence of the injury.
