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.
Movement at the PIP and DIP joints occurs as the tip. of the finger is brought toward the anterior surface of the. palm in flexion. The finger is in full extension in anatomi-. cal position and ordinarily there is no additional range of. extension available. Average range of motion for finger. flexion at the PIP joint is 1000; average range of motion at. the DIP joint is 85 0â90. Abduction and adduction at the MCP joint occurs in. the frontal plane (Figure 11.8). Abduction is different for. the four fingers because finger abduction is movement.
