Reliability and concurrent validity of the “Awareness of Functional Tasks with Arm and Hand in Stroke” (AFAS) scale

      About 70% of people post-stroke have upper extremity impairments and 81% have mental body representations deficits (MBRs), such as body awareness.[1] Yet, the relationship between body awareness and motor deficits post-stroke is not clear. Current scales look at either quality of movement[2] or body awareness (in other populations).[3-4] We designed the “Awareness of Functional Tasks with Arm and Hand in Stroke” (AFAS) scale for stroke, that assesses both quality of movement (AFAS-M) and body awareness (AFAS-A). We investigated inter-rater reliability, standard error of measurement (SEM), minimal detectable change (MDC(95)), and convergent validity in adults with stroke. We reported on deficits in proprioception (position and movement sense), 2-point discrimination (2PD) and stereognosis.
