Aim:
To measure functional change in 10 adults following severe traumatic brain injury using the Assessment of Motor and Process Skills (AMPS).
Methods:
This clinical pilot study used a standardised occupational therapy tool, the AMPS, to measure motor and process scores during activities of daily living, for over 3 weeks of inpatient rehabilitation.
Results:
Wilcoxon signed ranks tests indicate significant improvement in motor and process scores from initial assessment to repeat evaluation (z = -2.70, p = 0.01; z = -2.81, P = 0.01, respectively).
Conclusions:
The AMPS measured statistically and clinically significant change in motor and process abilities over 3 weeks of neurosurgical rehabilitation. Findings suggest that the AMPS is a sensitive measure of functional change for the study sample and timeframe.
