An apparatus for a complimentary treatment of spasmodic torticollis

We have developed an apparatus for treating spasmodic torticollis that can be used at home both during intensive therapy and follow-up. The refractoriness of spasmodic torticollis requires patients to practice biofeedback training partly on a home basis. However, it is usually difficult for spasmodic torticollis patients to provide and handle electromyographic (EMG) biofeedback training instruments. The present apparatus has 2 parts: first, a harness with a light source which is fixed on both shoulders; second, a photoreceptor, operant system for rewarding effect, and a digital recorder. The light is adjusted to strike the photoreceptor on the forehead when headposition is normal. Subjects are asked to keep the operant system--e.g. a radio--activated. They are trained in various postures as sitting, standing and walking. This apparatus provides a chance of home training to augment and maintain the effect during therapeutic sessions and the follow-up period.
