Joint stability refers to the ability of a joint to maintain its position and function during movement. It is influenced by the surrounding muscles, ligaments, and tendons that support the joint. Proper joint stability helps prevent injuries and allows for smooth, coordinated movements. Factors affecting joint stability include muscle strength, flexibility, and proprioception, which is the body's awareness of joint position. Conditions such as arthritis or ligament injuries can compromise joint stability, leading to pain and decreased mobility. Maintaining joint stability is essential for overall physical health and performance in activities like sports and daily tasks.
