Occupational therapy to optimise independence in Parkinson's disease: the designing and recording of a randomised controlled trial intervention

PDOT (Parkinson's Disease Occupational Therapy) was a pilot randomised controlled trial investigating occupational therapy for people with Parkinson's disease (PD) exhibiting difficulties with activities of daily living (ADL). This article describes the process undertaken to design and record the intervention.

Intervention development was informed by the current evidence base and practice consensus. An expert steering group synthesised this information to develop an intervention framework. A recording tool was identified from a previous occupational therapy trial and adopted for PDOT. This was completed for all participants receiving the intervention, capturing the dose and content of therapy delivered.

Nineteen participants received occupational therapy. A mean number of 5.7 visits was delivered over 60.3 days, with the initial visit lasting 60 minutes (median) and subsequent visits lasting 50 minutes (median). The intervention log demonstrated that a large proportion of therapist visits involved equipment provision/environmental adaptation, mobility/transfers/ADL training, review/discussion, and the teaching of techniques/provision of education.

The intervention developed was found to be feasible and acceptable, and the findings of PDOT have been used to inform a phase III rehabilitation trial (PD REHAB). The intervention log has been revised in light of the findings and will be used within this trial.
