The feasibility of a self-regulation and mental imagery programme to enhance everyday functioning for people with Parkinson's disease: study protocol.

BACKGROUND

Less dopaminergic neurons in people with Parkinson's disease result in a reliance on a slow and energy-intensive control, restricting their ability to complete routine everyday activities. Self-regulation takes an active learning approach to rehabilitation by enhancing the person's self-awareness and encourages self-reflection to overcome problems. Mental imagery assists the person to focus attention on the requirements for the task, making it a goal-directed action and allowing for faster movements. There is a growing body of evidence to support the use of self-regulation and mental imagery in rehabilitation to maintain or improve the performance of everyday activities for people with a neurological condition.

METHODS

A prospective pilot study using a single-group, pre-test and posttest design will test the feasibility and acceptability of a self-regulation and mental imagery programme to enhance performance of everyday activities and motor and cognitive function in people with Parkinson's disease. People who have a diagnosis of Parkinson's disease with mild-to-moderate severity and intact attention, comprehension and short-term memory will be recruited. The participants will receive a 6-week programme with one therapist-led session, a home programme and a telephone call each week. The programme uses self-regulation through a step-based problem-solving process and mental imagery to assist in movement planning. Appropriate rehabilitation strategies are used as solutions to tackle problems experienced, impacting performance in everyday activities. The attendance rate will be recorded to indicate the feasibility. A questionnaire will be administered post-intervention to collect feedback on programme acceptability. Patient outcomes will include Barthel index, Lawton Instrumental Activities of Daily Living Scale, Canadian Occupational Performance Measure and Timed Up and Go test. Trail Making Test and Montreal Cognitive Assessment will be collected pre- and post-intervention.

DISCUSSION

The programme aims to combine the metacognitive strategies of self-regulation and mental imagery to enable individuals with Parkinson's disease to improve the performance of everyday activities. If feasible, the programme has the potential to be further tested in a randomised controlled trial and benefit people with Parkinson's disease by enhancing their performance required in independent community living.
