Use of antecedent control to improve the outcome of rehabilitation for a client with frontal lobe injury and intolerance for auditory and tactile stimuli.

KM, a single 23-year-old male, sustained a severe traumatic brain injury in a motor vehicle accident. Aggressive and uncooperative behaviour, resulting from the client's cognitive deficits and hypersensitivity to stimuli, made him unmanageable in a subacute rehabilitation setting. Minimizing sources of agitation reduced the client's outbursts and facilitated the completion of functional tasks, such as bathing and dressing. Modifying his environment also increased the client's participation in social and leisure activities. These changes improved the outcome of the client's rehabilitation.
