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.
The majority of the hand. placement and range of motion tasks that were studied in this project could be accomplished. with 70 percent of the maximal range of wrist motion. This converts to 40 degrees each of wrist. flexion and extension, and 40 degrees of combined radial-ulnar deviation. This study provides normal standards for the functional range of motion of the wrist.
