A history of subclinical neck pain is associated with lower neck muscle endurance capacity and with less rotation range of motion on second testing but when frequent (occurring weekly or more often) is associated with greater sensitivity in judging neck movement extent. Improving strength and rotation range should therefore be investigated as targets of treatment for subclinical neck pain.
