Neck pain often arises from tight neck muscles that pull the neck vertebrae slightly out of alignment, called subluxation, which then impinge on sensory nerves entering the spine between these vertebrae. These sensory nerves relay that information back to the brain setting off the alarm in the form of pain.
Wrist Bending. Forward bending of your wrist is called flexion. This motion is needed for daily activities such as styling your hair, writing, getting dressed, using a screwdriver and lifting heavy objects. Normal wrist flexion is approximately 70 to 90 degrees.
It should be recognized that the range of motion (ROM) of joints is not exactly the same among reporting authorities. For example, the reported normal flexion of the lumbar spine may vary between 80Â° and 100Â°.The value cited below is 90Â°, but 80Â° flexion should not interpreted as abnormal. The range of ânormalâ motion also decreases with age, particularly in the spine.urpose. Range of motion (ROM) tests may be used to: 1  Determine range of motion (ROM) of joints or spine. 2  Determine the angular deviation of the spine caused by abnormalities such as kyphosis.
