### What is normal range of motion?

Joint range of motion refers to both the distance a joint can move and the direction in which it can move. There are established ranges that doctors consider normal for various joints in the body. For example, one study determined a normal knee should ideally be able to flex, or bend, to between 133 and 153 degrees.

### What causes limited range of motion in knee?

Motion may be limited because of a problem within the joint, swelling of tissue around the joint, stiffness of the ligaments and muscles, or pain.

### How can I improve my knee flexion?

Assume a sitting position in a chair with involved knee bent as able under chair. Position uninvolved foot in front and push back on involved leg to increase the bend. Hold the recommended time, and then gently release. Perform as a repetition-based exercise, or statically hold the stretch.
