Table 1.

Components of the overall impairment measure.

Component	Examiner	Points towards total
Weakness (by Motricity Index*)	Physician	0 = 4 points; 1–34 = 3 points; 35–64 = 2 points; 65–99 = 1 point; 100 = 0 points
Sensory loss	Physician	1 point if present
Visual field cut or visual neglect	Physician	1 point if present
Aphasia	Speech therapist	1 point if present
Spatial neglect	Occupational therapist	1 point if present
Cognitive Deficit**	Physician (MMSE) and therapists (FIM)	1 point if MMSE<24 or admission FIM Problem Solving <4

^*Motricity Index [36, 37] is a scale that converts a subset of the Medical Research Council (1 to 5 point) scale [38] into 0 to 100 points (0 no movement, 100 normal). It has been shown to correlate with the Rivermead Motor Assessment [39], Barthel ADLs [37], and with the Fugl-Meyer (r=0.87) in the 78% of our patients who had admission Fugl-Meyer performed.

^**Cognitive deficit was scored as present if Mini-Mental Status Exam (MMSE) <24 or FIM Problem Solving <4, as the MMSE is not sensitive to executive function deficits [40].
