Anthrokinematics
1. [noun] ' Arthrokinematics' refers to the movement of joint surfaces. The angular movement of bones in the human body occurs as a result of a combination of rolls, spins, and slides. A roll is a rotary movement, one bone rolling on another. A spin is a rotary movement, one body spinning on another. A slide is a translatory movement, sliding of one joint surface over another

Frequently Asked Questions
How does the combined motion of roll, spin, and slide manifest in the ankle during daily activities?
Everyday activities like walking and stepping onto uneven surfaces allow the ankle to perform rolling, spinning, and sliding movements. These coordinated joint movements help adjust to weight changes and maintain balance.
Can you give an everyday example that shows the joint motion in the foot?
When you step off a curb, your ankle joint surfaces engage in a combination of rolling and sliding. This coordinated motion lets your foot smoothly adapt to differing heights without abrupt shifts.
How can understanding the Greek roots of arthrokinematics improve our grasp of foot joint movements?
Knowing that 'arthro' means joint and 'kinematics' means motion helps highlight that the combined roll, spin, and slide movements in the foot’s joints are essential for fluid and adaptive mobility.
