Relationships between cognitive abilities and the process scale and skills of the assessment of motor and process skills (AMPS) in patients with stroke

The purpose of this study was: 1) to determine the strength of the relationships between cognitive components at the body function/impairment level to the assessment of motor and process skills (AMPS) at the occupational performance/activities level in persons following stroke; and 2) to examine which cognitive components best explain the variance of the AMPS score. Stroke is a major cause of disability in older age that can result in motor and/or cognitive impairments leading to functional disability. The assessment of AMPS is an activity of daily living (ADL) and instrument activity of daily living (IADL) evaluation that measures two aspects enabling occupational performance and motor and process skills. Subjects included 30 hospitalized patients 4 to 5 weeks following stroke. Among them were 17 men and 13 women with a mean age of 71.33 (SD = 8.39) who had been independent in ADL prior to the event. Instruments included the AMPS IADL tasks, Thinking Operations from the LOTCA, Contextual Memory Test, Rey Complex Figure-copy, Star cancellation from the BIT, and COGNISTAT. The study supports the existence of moderate relationships between cognitive components and the AMPS' process scale and skills, and the results add information about relationships between cognitive impairments and occupational performance that can help in treatment planning.
