ABSTRACT:
Apparatus for treating spasmodic torticollis comprises a light emitter for giving off a light beam, a fastener band for fastening the light-emitter on the head of a person being treated, a photosensor which is responsive to a light beam from the light emitter to change its output and a support for supporting the photosensor in a fixed position with respect to the chest of the person so that the photosensor may receive a light beam from the light emitter while the person holds his head in a mid position. The apparatus includes a switching circuit which responds to an output from the photosensor to control its output, an operant which responds to an output from the switching circuit to produce a rewarding effect, an accumulator which responds to the output from the switching circuit to produce an electrical signal directly proportional to the period during which the switching circuit is turned on, and a digital display which responds to an electrical signal from the accumulator to provide a digital reading of the total time period in a session during which the person has been able to hold his head in the mid position.
