The Mathew stroke scale is used to measure the degree of impairment from stroke 1. It was originally developed to evaluate the neurological status of patients treated with glycerol in acute stroke.
- level of consciousness: comatose (0), stuporous (2), obtunded (4), lethargic but mentally intact (6), fully conscious (8)
- orientation to time, place and person: disoriented (0), oriented x 1 (1), oriented x 2 (2), oriented x 3 (3)
- Reitan speech function: 0-23
- homonymous hemianopia: intact to severe (0-3)
- conjugate deviation of eyes: intact to severe (0-3)
- facial weakness: intact to severe (0-3)
- motor power (each limb): no movement – normal power (0-5)
- performance or disability status scale: death, severe-mild impairment or normal (0-28 in increments of 7)
- reflexes: none elicited – normal (0-3)
- sensations: no response to pain, mild-severe sensory abnormality, normal (0-3)
The scale ranges from 0 (indicating death) to 100, with a lower value indicating a greater degree of severity. It is has been criticized for issues with internal consistency and interobserver reliability 2,3.
