What are the three arthrokinematic movements?

The three arthrokinematic movements are roll, glide, and spin. These movements describe the manner in which joint surfaces interact during motion.

In a rolling movement, one surface rolls over another, similar to how a tire rolls down the road. This movement is crucial in joints like the hip or knee during activities such as walking or running.

Gliding occurs when two surfaces slide over one another, allowing for smoother motion and improved range of motion. In joints like the wrists and ankles, gliding is essential for coordinating movements as you use your hands or feet.

Spin describes the rotation of one joint surface around another, akin to how a top spins on a surface. This motion is particularly evident in joints such as the shoulder and hip, where rotation is vital for various functional activities.

Understanding these three arthrokinematic movements is essential in biomechanics, as they play a critical role in joint function, movement efficiency, and overall physical activity.
