SARA consists of a clinical evaluation of eight items: gait, stance, sitting, speech disturbances, finger-chase, nose-finger-test, fast alternating hand movements, and heel-shin slide. SCAFI is composed of a timed 8 m walk at maximum speed (8MW), the 9-hole peg test (9HPT) for fine motor skills, and the PATA rate, a measure of speech performance.
