A treatment model for motor tics based on a specific tension-reduction technique.

A model is proposed in which motor tics are considered to be tension reducing responses to a specific sensory stimulus. It is hypothesized that the sensory stimulus is of a proprioceptive nature. The first phase of therapy concerns the identification of the stimulus. The patient is then taught a socially acceptable, alternative response, which also reduces the sensory stimulus. Two case reports illustrate this model. The applicability of the model with respect to other movement disorders is discussed.
