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.
Limited Range of Motion. Common Causes of Limited Range of Motion. Limited range of motion is a condition that exists when a joint is unable to bend or otherwise move to its usual extent, when rotation, flexion, or extension motions are impeded. Limited range of motion can occur as a result of many conditions, including injury or other trauma, disease, and disuse, as well as certain congenital conditions.
