ABSTRACT:
Method and apparatus for testing and/or exercising the rotary neck muscles which are used to twist or turn the neck from side-to-side about a generally vertical pivot axis passing through the cervical vertebrae. The head is held by and between a pair of pads mounted on a rotatable frame fixed to a movement arm in the form of a vertical pivot shaft rotatable about the pivot axis. The movement arm is connectable to resistance weight stack to oppose pivotal movement of the movement arm in one direction. During exercise, the subject is seated against a backrest with a front pad assembly immobilizing the chest and shoulder areas of the subject. Additionally, the head pads prevent forward and rearward movement of the neck in extension and flexion so that only the rotary torsion muscles of the neck are exercised.
