Stroke can result in severe motor deficits, and many people who have survived a stroke have poor cardiovascular fitness, with potentially disabling effects on daily life.
The objective of this study was to evaluate the impact of intensive physical training on gait performance and cardiovascular health parameters in people with stroke in the chronic stage.
This was a single-group, pretest-posttest experimental study.
Fourteen people with hemiparesis after cerebrovascular injury (mean age=58.4 years, mean time since injury=25 months) participated in a 12-week training intervention, 5 times per week for 1.5 hours per session. The intervention consisted of high-intensity, body-weight-supported treadmill training; progressive resistance strength training; and aerobic exercise. The main outcome measures were gait performance (Six-Minute Walk Test, 10-Meter Walk Test, and aerobic capacity) and parameters of cardiovascular health (systolic and diastolic blood pressures, body mass index, and resting heart rate).
Significant improvements in all main outcome parameters were observed in response to the intervention. Gait speed during the Six-Minute Walk Test increased 62%, and systolic and diastolic blood pressures decreased 10% and 11%, respectively. Weekly testing of walking speed showed that most of the increase in the walking speed occurred in the first 8 weeks of training. Correlation analyses showed that improvements were unrelated to age, chronicity, or level of functioning.
High-intensity physical training for people with stroke in the chronic stage increased walking speed regardless of chronicity, age, or level of functioning. Further studies should investigate the intervention duration needed to reach the full potential of gait recovery.
中风可导致严重的运动功能障碍，许多幸存下来的中风患者心血管健康状况不佳，这可能对日常生活造成致残影响。
本研究旨在评估强化体能训练对慢性期中风患者步态表现和心血管健康参数的影响。
这是一项单组、前后测试的实验研究。
14 名患有脑血管损伤后偏瘫的患者（平均年龄=58.4 岁，损伤后时间平均=25 个月）参与了为期 12 周的训练干预，每周 5 次，每次 1.5 小时。干预包括高强度、体重支撑跑步机训练、渐进式阻力力量训练和有氧运动。主要结局指标为步态表现（6 分钟步行测试、10 米步行测试和有氧能力）和心血管健康参数（收缩压和舒张压、体重指数和静息心率）。
干预后，所有主要结局参数均显著改善。6 分钟步行测试中的步态速度提高了 62%，收缩压和舒张压分别降低了 10%和 11%。每周测试步行速度显示，在训练的前 8 周内，步行速度的大部分增加发生。相关性分析表明，改善与年龄、慢性期或功能水平无关。
对于慢性期的中风患者，高强度的体能训练可提高步行速度，无论慢性期、年龄或功能水平如何。进一步的研究应该调查达到步态恢复全部潜力所需的干预持续时间。
