Abstract: A method and apparatus are described for assessing function of the cranio-cervical muscles. The method includes assessment of torque produced during flexion/extension, axial rotation, lateral rotation or combination thereof. The apparatus (110) has a lever arm (130) mounted to a support frame (120), wherein the length of the arm and its angle of extension may be varied. Torque is assessed at an anatomical axis of rotation in a subject. The apparatus axis of rotation may be adjustable. A preferred embodiment has a pivoted support frame for positioning over a subject's head, wherein the support frame (120) may form a lever arm for rotation. The apparatus may be removably mountable to an upright such as a door jamb.
