Range of motion is typically measured using a tool called a goniometer. Normal ROM at the knee is considered to be 0 degrees of extension (completely straight knee joint) to 135 degrees of flexion (fully bent knee joint). Most functional activities require 0 to 117 degrees of motion at the knee.
Extension is the opposite movement, which increases the angle at the joint. Many types of synovial joint are capable of flexion and extension (hinge; ball and socket; saddle; condyloid) including the shoulder, elbow, wrist, hip and knee.n the videos above, shoulder flexion is the action of raising the arm above the head. Extension is then the downward movement. In the photo, the shoulder is in an extended position. For the knee, bending the knee is flexion, as the angle is reduced (as shown in the picture) and straightening it is called extension.
