Efficacy and safety of very early mobilization after thrombolysis in acute ischemic stroke: a randomized clinical trial.

BACKGROUND: Stroke has a deleterious impact on human health due to its high incidence, degree of disabling sequelae and mortality, constituting one of the main causes of death and disability worldwide. OBJECTIVES: This study aimed to assess the efficacy and safety of very early mobilization (VEMG) after thrombolysis in functional recovery in patients with acute ischemic stroke. METHODS: The present study was an open, prospective, randomized study, with no blinded outcome, carried out in the stroke unit of a tertiary referral hospital located in Salvador-Bahia, Brazil. The primary outcome was the level of functional independence. Secondary outcomes were functional mobility, balance, complications within 7 days of hospitalization and 90 days after hospital discharge, and length of stay. OUTCOMES: A total of 104 patients with ischemic stroke who received thrombolytic treatment between August 2020 and July 2021 were prospectively recruited to the study. Of these, 51 patients received VEMG within 24 h of the ictus and another 53 patients receiving usual care (UCG) with mobilization 24 h after the ictus. When compared to the usual care, the VEMG group was not associated with a significant reduction in the risk of the primary outcome (relative risk [95% confidence intervals]: 0.74 [0.339-1.607]) or any of the secondary outcomes. CONCLUSION: In this study, the strategy of early mobilization after thrombolysis in ischemic stroke was safe, but without evidence of short-term benefit.

The impact Of high-intensity interval training On functioning And health-related quality Of life In post-stroke patients: A systematic review With meta-analysis.

OBJECTIVE: To examine the effects of high-intensity interval training on the functioning and health-related quality of life of post-stroke patients. METHODS: We searched the following electronic databases: MEDLINE/Pubmed, Cochrane Central Register of Controlled Trials, PEDro database, and Scielo up to January 2022 for randomized controlled trials that investigated the effects of high-intensity interval training in post-stroke patients. Two reviewers selected the studies independently. Study quality was evaluated using the PEDro scale. The mean difference (MD), standard mean difference (SMD), and 95% confidence intervals (CIs) were calculated. RESULTS: Nine studies met the study criteria (375 patients). The age of the participants ranged from 55.8 to 72.1 years. The studies included patients within 2 weeks of stroke onset to patients longer than 1 month of stroke. High-intensity interval training resulted in improvement in cardiorespiratory fitness (peak oxygen uptake) MD (3.8 mL/kg/min, 95% CI: 2.62, 5.01, n = 91), balance MD 5.7 (95% CI: 3.50, 7.91; N = 64), and gait speed SMD (0.2 m/s; 95% CI: 0.05, 0.27; N = 100) compared with continuous aerobic training. The health-related quality of life did not differ between the groups. Compared to usual care, high-intensity interval training improved the cardiorespiratory fitness SMD (0.5 95% CI: 0.14, 0.81, n = 239). No serious adverse events were observed. CONCLUSIONS: The findings of this systematic review show that high-intensity interval training was more efficient than continuous aerobic training to gain cardiorespiratory fitness, balance and gait speed in post-stroke patients. In addition, compared to usual care, high-intensity interval training improved cardiorespiratory fitness.
