Evaluation of The Perceive, Recall, Plan and Perform Intervention for Persons With Cognitive Impairments After Brain Injuries in Community Rehabilitation: Single Case Experimental Study
In Brief
A clinical study evaluating The Perceive, Recall, Plan and Perform System of Intervention for Brain Injuries and Cognitive Impairment. Completed, enrolled 6 participants across 2 sites.
Detailed Summary
Background: There is a need for standardized interventions in community rehabilitation that can improve everyday task performance for older adults with cognitive challenges after acquired brain injury. Older adults are often excluded from research due to strict inclusion criteria. It is critical for a sustainable health service system that these patients are empowered and reach their maximum level of independence. The Perceive, Recall, Plan and Perform System (PRPP) of Intervention can be applied by Occupational Therapists (OT) for clients with cognitive challenges to enhance mastery of needed or desired everyday tasks. There is no current evidence for the effectiveness of this intervention for this population. Purpose: A clinical trial to investigate the effectiveness of the PRPP intervention for older persons with cognitive impairments after brain injury in the context of community-based rehabilitation. Method: In PRPP intervention the OT uses systematically instructions in task training to support a client to use cognitive strategies efficiently. The everyday tasks used for training should be valued by the participant and useful in their rehabilitation. The tasks could include different parts of morning routines, simple or complex meal planning or preparation, use of cell phone, leisure activities, or other household and community activities. At best the skills are generalized throughout all everyday activities, and the OTs' role as a cognitive mediator fades as participants internalize the strategies. The participants receive PRPP intervention 3 times a week for 3 weeks, every session last for 45-60 minutes. The participants' task mastery and cognitive strategy use will be measured at least 5 times in each phase: baseline, intervention, after the intervention, and 4 weeks after the discharge from rehabilitation. The measurement scores at baseline act controls and are therefore compared with the other phases for the same participant. The same procedure will be repeated for the other participants, but then with a staggered intervention phase. A staggered intervention phase acts as a control between participants and allows to see if changes occur only when the intervention is introduced. Implications for practice: The investigators assume that this systematic intervention will improve everyday task performance, and will in turn contribute to empowerment and independence of older adults with cognitive challenges after brain injuries.

Timeline
Interventions
The aim of the PRPP intervention is to enhance mastery in performance of needed or desired occupations, and extend traditional task training. Systematic instructions to support the clients' cognitive capacity to think about doing in different tasks and contexts are given by the OT, based on the results of PRPP Assessment stage 2. Further, the OT uses graded verbal, visual or physical prompts and cues directly during the participants task performance, progressing from content-free meta-prompts 'Stop' to alert the participant to process information required for the task, and for errorless learning. Then the OT prompt 'sense/attend, think and do', to more specific behavioural prompts selected by the therapist based on the components from the PRPP Assessment stage 2. At best the skills are generalized throughout all everyday activities, and the OTs' role as a cognitive mediator fades as the person internalize the strategies.
