This study developed a comprehensive measure of Early Physical Functioning (EPF) post-stroke quantified through Rasch analysis and conceptualized using the International Classification of Functioning Disability and Health (ICF). Functional assessments were made in 262 subjects within 3 days of stroke with items from valid and reliable indices commonly utilized to evaluate stroke survivors. A 38-item unidimensional measure of the EPF met all Rasch model requirements. The item difficulty matched the person ability, reliability of the person-item-hierarchy was excellent. Initial validity was adequate.
The 38-item EPF measure was developed. It expands the range of assessment post acute stroke; it covers a broad spectrum of difficulty with good initial psychometric properties that, once revalidated, can assist in planning and evaluating early interventions.
