OBJECTIVE: To investigate factors within 3 days post-stroke that could predict
severe impairment in motor function in the upper extremity at one month post-stroke. METHODS: This cross-sectional study included 104 patients with
first-ever stroke and impaired motor function in the upper extremity. Initial
impairment in motor function, demographic data, type of stroke and stroke risk
factors were chosen as possible predictors. Severe impairment in motor function
was defined as </= 31p according to the Fugl-Meyer Assessment for Upper Extremity
(FMA-UE). Logistic regression was used to predict severe impairment in motor
function at one month post-stroke. RESULTS: Three possible prediction models were
found, comprising stroke severity combined with grip strength and sex, finger
extension or shoulder abduction. Models including grip strength or finger
extension gave the most accurate predictions, with overall predictive ability
90.4% (95% confidence interval (95% CI) 0.847-0.961) and sensitivity 92.9% (95%
CI 0.851-1.0) and 90.5% (95% CI 0.816-0.979), respectively. CONCLUSION: Within 3
days post-stroke, severe impairment in motor function in the upper extremity at
one month can be predicted using assessment of stroke severity in combination
with grip strength, finger extension or shoulder abduction. This may facilitate
early planning of rehabilitation for patients with impaired upper extremity in
the stroke unit.
