Which type of joint exhibits less motion than is typically considered functional?

A hypomobile joint is characterized by restricted motion, exhibiting less range of motion than is typically considered functional. This condition can occur due to various factors such as injury, inflammation, or other underlying health issues, which limit the ability of the joint to move freely. Understanding hypomobility is crucial in physical therapy, as addressing this limitation often becomes a primary focus in rehabilitation to restore normal function and movement patterns.

In contrast, amphiarthrodial joints, like those found between the vertebrae, allow for slight movement but are not typically classified as less functional—they serve a specific purpose in providing stability while allowing limited flexibility. Stable joints, while they may offer support and maintain position, do not inherently define a reduced range of motion. Synovial joints are actually known for their wide range of motion and fluid movement, thus are the opposite of what hypomobility represents. Therefore, recognizing hypomobile joints as those with compromised motion leads to better treatment strategies in physical therapy practices.
