STUDY GUIDE INSTRUCTIONS
▸ Questions cover the NIH Stroke Scale (NIHSS) and Stroke Rehabilitation Assessment of Movement (STREAM).
▸ Select the single best answer for each question based on standardized stroke assessment and rehabilitation protocols.
▸ Pay careful attention to scoring ranges, severity cut-offs, and psychometric properties (MDC, MCID).
▸ Correct answers and detailed rationales appear below each question for comprehensive exam preparation.

OUTCOME PREDICTION – 30
1. The NIH Stroke Scale (NIHSS) is best defined as:
A. A surgical procedure to remove blood clots
B. An international measure used by multiple disciplines to rate the severity of stroke
C. A medication protocol for acute ischemic stroke
D. A diagnostic imaging technique for brain hemorrhages
CORRECT ANSWER B. An international measure used by multiple disciplines to rate the severity of stroke
RATIONALE The NIHSS is the gold-standard, standardized neurological examination tool used internationally by
physicians, nurses, and therapists to quantify stroke-related neurological deficits. It objectively measures
impairment across consciousness, vision, motor function, sensation, language, and neglect. It is not a surgical
procedure, medication protocol, or imaging technique.
, 2. What does the NIH Stroke Scale examine and measure?
A. Only blood pressure and heart rate abnormalities
B. Post-CVA neurological deficits quantitatively
C. Psychological adjustment to disability
D. Pre-stroke functional independence
CORRECT ANSWER B. Post-CVA neurological deficits quantitatively
RATIONALE The NIHSS provides a quantitative score (0–42) representing the severity of neurological impairment
following a cerebrovascular accident (CVA/stroke). It assesses 13 specific domains: level of consciousness,
gaze, visual fields, facial palsy, motor function (arms and legs), limb ataxia, sensory, language, dysarthria, and
extinction/inattention. It does not measure psychological adjustment or pre-stroke function.
3. The NIH Stroke Scale is classified as what type of outcome measure?
A. Participation-based outcome measure
B. Impairment-based outcome measure (motor and cognition)
C. Quality of life outcome measure
D. Caregiver burden outcome measure
CORRECT ANSWER B. Impairment-based outcome measure (motor and cognition)
RATIONALE The NIHSS is an impairment-based measure within the ICF framework—it assesses body function and
structure deficits (motor control, language, vision, consciousness, sensory) rather than activity limitations or
participation restrictions. It captures the direct neurological consequences of the stroke lesion. STREAM, in
contrast, assesses voluntary movement and basic mobility (activity level).
4. How many items are assessed by the NIH Stroke Scale?
A. 10 items
B. 13 items
C. 15 items
D. 20 items
CORRECT ANSWER B. 13 items
RATIONALE The 13 NIHSS items: (1) LOC-Responsiveness, (2) LOC-Questions, (3) LOC-Commands, (4) Best Gaze, (5) Visual
Fields, (6) Facial Palsy, (7) Motor Arm Left, (8) Motor Arm Right, (9) Motor Leg Left, (10) Motor Leg Right, (11)
Limb Ataxia, (12) Sensory, (13) Best Language, plus Dysarthria and Extinction/Inattention (often grouped for a
total of 15 scored parameters within the 13 categories).
5. What is the total possible score range for the NIHSS?
A. 0–30
B. 0–42 (higher score = more severe deficits)
C. 0–100
D. 1–10
CORRECT ANSWER B. 0–42 (higher score = more severe deficits)
RATIONALE NIHSS total scores range from 0 (no impairment) to 42 (maximum severity). Higher scores indicate more
severe neurological deficits and generally predict poorer outcomes. A score of 0 indicates no measurable
stroke-related neurological deficit. The scale is ordinal, with each item contributing a weighted score based
on the severity of that specific impairment.
