Despite the inevitable loss of function seen in people with progressive dementias, interventions for reversing or minimizing functional loss are understudied. Research supports task-oriented training, but practical gaps in how to best evaluate clients for this training and how to implement it in clinical settings may be thwarting translation to occupational therapy practice. We structured an intervention model called STOMP (Skill-building through Task-Oriented Motor Practice) using a unique blend of task-oriented training and motor-learning principles. In this article, we describe through a case study the process and outcome of using STOMP to improve functional skills in a woman with moderate dementia with Lewy bodies. Our findings suggest that STOMP has the potential to serve as a structure for the evaluation and treatment of occupational performance deficits in people with dementia and that this model warrants further investigation.
