Range of motion (ROM) is a measurement of movement around a joint. Measuring ROM is helpful to assess flexibility, ability to work and fitness. 

According to Kurz, the following tables indicates the normal ranges of joint motion for various parts of the body:

Flexion: 70-90 degrees

Touch sternum with chin.
Extension: 55 degrees
Try to point up with chin.
Lateral bending: 35 degrees
Bring ear close to shoulder.
Rotation: 70 degrees left & right
Turn head to the left, then right.

Lumbar Spine
Flexion: 75 degrees
Bend forward at the waist.
Extension: 30 degrees
Bend backward.
Lateral bending: 35 degrees
Bend to the side.

Abduction: 180 degrees
Bring arm up sideways.
Adduction: 45 degrees
Bring arm toward the midline of the body.
Horizontal extension: 45 degrees
Swing arm horizontally backward.
Horizontal flexion: 130 degrees
Swing arm horizontally forward.
Vertical extension: 60 degrees
Raise arm straight backward.
Vertical flexion: 180 degrees
Raise arm straight forward.

Flexion: 150 degrees
Bring lower arm to the biceps
Extension: 180 degrees
Straighten out lower arm.
Supination: 90 degrees
Turn lower arm so palm of hand faces up.
