Assessment of Stroke Outcome Based on Initial Stroke Severity Measured on Different Stroke Severity Scales
Keywords:Stroke, cerebrovascular accident, outcome assessment
AbstractBackground: Stroke is the second most common cause of death globally and the major cause of disability. Though
a number of studies have been conducted on stroke outcome and recovery of walking function, the list and effects
of predictive factors are still a major challenge to stroke rehabilitation.
Materials and methods: This was a randomized prospective study to evaluate whether initial stroke severity
influences the stroke outcome. The patients were categorized after CT scan into two groups (group I- infarction type
and group II haemorrhagic type). Initial stroke severity was evaluated in Scandinavian Stroke Scale (SSS). Functional
status was evaluated after admission in Functional Independence Measure (FIM), Barthel Index (BI) and Short
Form- 36 (SF- 36).To see the outcome in relation to time patients were evaluated with FIM, BI and SF- 36 four weeks
Results: Analysis of Scandinavian Stroke Scale indicated that the overall score was higher among the patients with
cerebral infarct (mean score 29.25) compared to patients with cerebral hemorrhage (mean score 20.08) and the
mean difference was statistically significant (p<0.001). Analysis of Barthel Index indicated that the percentage of
improvement was significantly high among the patients with cerebral hemorrhage compared to cerebral infarct in
terms of transfers from bed to chair or vice versa (p<0.001). However, improvement was also high among the
patients with cerebral hemorrhage as well as cerebral infarct, but the difference was not statistically significant
Conclusion: This study indicates that initial motor, sensory and cognitive impairment can be good predictor in
amount and time period of recovery of mobility function and other aspect in acute stroke patients, as data shows that
milder the initial impairment faster and more is the recovery.
