Background: Regular physical activity is known to have a beneficial impact on multiple cardiovascular risk factors, but there is no routine provision of exercise training programs to patients after ischemic stroke.

Objectives: To assess the tolerability, safety and effect of an outpatient supervised exercise training program in patients after a non-disabling ischemic stroke.

Methods: Patients discharged home following a minor ischemic stroke (modified Rankin scale; mRS ≤ 2) were referred to a 3 month outpatient supervised exercise training program, performed twice weekly as prescribed by a physiologist and supervised by physical therapy. Exercise capacity was evaluated by the 6 minute walk test, and by the modified Bruce exercise test.

Results: Of the 52 patients who met the selection criteria, 43 underwent supervised exercise training within 2 months of stroke onset and 9 did not (control group). The baseline characteristics were comparable between the two groups. Following the exercise training program, an improvement in exercise capacity was observed manifested by improvement in the 6 minute walk test (444 ± 90 to 557 ± 99 meters in the exercise group vs. 438 ± 101 to 418 ± 126 in the control group; P = 0.002 for the score changes) and in the exercise duration achieved in the modified Bruce test and the metabolic equivalents achieved [9.6 ± 3.7 to 12.4 ± 3.2 minutes and 6.2 ± 2.8 to 8.5 ± 3.4 respectively in the exercise group (n=41) vs. 9.2 ± 3.5 to 8.0 ± 3.4 min and 5.8 ± 1.8 to 5.8 ± 2.8 in the control group (n=7); P = 0.0009 and 0.01 for score changes, respectively].

Conclusions: An outpatient supervised exercise training program after a minor ischemic stroke is feasible, well tolerated and is associated with improvement in exercise capacity. We strongly recommend that an aerobic exercise program be offered to suitable patients after an ischemic stroke.

 Background: Clinical trials have demonstrated the superiority of managing acute stroke in a dedicated stroke unit over conventional treatment in general medical wards. Based on these findings, nationwide stroke unit care programs have been implemented in several countries.

Objective: To assess the effect of establishing a new dedicated acute stroke unit within a department of neurology on indicators of process of care and outcome of acute stroke in a routine clinical setting in Israel.

Methods: Stroke patients admitted to the Sheba Medical Center during the period March 2001 to June 2002 were included in a prospective study according to selection criteria. Data on demographics, risk factors, co-morbidities and stroke severity were collected. Indicators of process of care and outcome were assessed at hospital discharge and 30 days follow-up. Comparison between outcome variables by hospitalization ward was conducted using logistic regression analysis adjusting for confounders.

Results: Of 616 acute stroke patients (mean age 70 years, 61% men, 84% ischemic stroke), 353 (57%) were admitted to general wards and 263 (43%) to the stroke unit. Diagnostic procedures were performed more often, and infection rate was lower in the setting of the stroke unit. Poor outcome (modified Rankin scale ≥3 or death) was present less often in patients managed in the stroke unit both at hospital discharge (adjusted odds ratio 0.5, 95% confidence interval 0.3–0.8) and at 30 day follow-up (adjusted OR[1] 0.6, 95%CI[2] 0.3–0.9). A Functional Independence Measure score ≤90 or death at 30 day follow-up was less frequent among patients managed in the stroke unit than in general wards (adjusted OR 0.5, 95%CI 0.2–0.8).

Conclusions: Improved outcomes and higher adherence to guidelines were observed in patients treated in a stroke unit within a department of neurology. The results suggest that patients with acute stroke should have access to treatment in a dedicated stroke unit.
