Effective occupational therapy intervention with adults demonstrating agitation during post-traumatic amnesia

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Occupational Therapy

Background:

• Brain injuries often result in agitation and post-traumatic amnesia (PTA), significantly impacting occupational performance.
• Current occupational therapy (OT) interventions may not fully address the information processing deficits associated with these conditions.

Purpose of the Study:

• To evaluate the efficacy of the Perceive, Recall, Plan and Perform (PRPP) System as an occupational therapy intervention for adults with agitation and PTA post-brain injury.
• To compare the PRPP System's effectiveness against standard OT interventions in improving information processing capacity during occupational tasks.

Main Methods:

• A single-system experimental (ABAB) design was employed across eight subjects undergoing acute rehabilitation.
• Intervention involved alternating standard OT with the PRPP System over four weeks, with daily therapy sessions.
• Information processing capacity was assessed using the PRPP System of Task Analysis, and PTA status was monitored with the Westmead PTA Scale.

Main Results:

• Seven out of eight subjects demonstrated significant improvements in applying processing strategies during PRPP Intervention phases compared to standard OT.
• The PRPP System intervention showed large treatment effects, indicating substantial benefits for participants.
• Enhanced information processing strategy use was observed both before and after subjects emerged from PTA.

Conclusions:

• Occupational therapy intervention utilizing the PRPP System of Task Analysis and Intervention effectively enhanced subjects' information processing strategy application during occupational performance.
• The PRPP System approach proved superior to current intervention methods for this patient population.
