Mathew stroke scale

The Mathew stroke scale is used to measure the degree of impairment from stroke . It was originally developed to evaluate the neurological status of patients treated with glycerol in acute stroke.

Classification

• 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)

Interpretation

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 .
