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.
CDC collected range of motion (ROM) measurements of the elbow, shoulder, hip, knee and ankle from a sample of individuals without known medical or physical conditions affecting the joint mobility. The objective was to generate data that could be used to: 1  Provide reference values for normal joint ROM for males and females and across the life span for comparison to people with hemophilia and other bleeding disorders.
