Abstract

BACKGROUND:

Approximately 80% of stroke survivors experience motor impairment of the contralateral limb that severely affects their activities of daily living (ADL).

OBJECTIVE:

To evaluate whether an enriched task-specific training (ETT) program affected the performance and kinetics of sit-to-stand (STS) tasks.

METHODS:

The study was part of an exploratory study with a within-subject, repeated-measure-design, with assessments before and after a three-week-long baseline period, and six months after the intervention. Forty-one participants underwent assessments of strength and endurance measured by the 30-second-chair-stand test (30sCST). The STS-kinetics, including the vertical ground reaction force (GRF) during STS, were analysed in an in-depth-subgroup of three participants, using a single-subject-experimental-design (SSED). For kinetic data, statistical significance was determined with the two-standard deviation band method (TSDB).

RESULTS:

After the baseline period, a small increase was seen in the 30sCST (from 5.6±4.5 to 6.1±4.9, p = 0.042). A noticeable significant change in the 30sCST was shown after the intervention (from 6.1±4.9 to 8.2±5.4, p < 0.001), maintained at six months. The in-depth kinetic analyses showed that one of three subjects had a significant increase in loading of the affected limb post-intervention.

CONCLUSION:

ETT can produce long-term gains in STS performance. Weight-bearing strategies could be one of several factors that contribute to improvements in STS performance in the chronic phase after stroke.

针对特定任务的强化训练对慢性中风患者坐立任务的影响

摘要：背景：大约 80% 的中风幸存者会出现对侧肢体运动障碍，严重影响他们的日常生活活动（ADL）。目的：评估强化特定任务训练（ETT）计划是否会影响坐立（STS）任务的表现和动力学。41 名参与者接受了 30 秒椅子站立测试（30sCST）对力量和耐力的评估。采用单受试者实验设计（SSED），对三名参与者组成的深度分组进行了 STS 动力学分析，包括 STS 期间的垂直地面反作用力（GRF）。结果：基线期后，30sCST 有小幅上升（从 5.6±4.5 到 6.1±4.9，p = 0.042）。干预后，30sCST 出现了明显的显著变化（从 6.1±4.9 到 8.2±5.4，p <0.001），并保持了六个月。深入的动力学分析表明，三名受试者中有一人在干预后患肢的负荷显著增加。结论：ETT 可使 STS 性能得到长期改善，负重策略可能是中风后慢性期 STS 性能改善的几个因素之一。

期刊介绍： NeuroRehabilitation, an international, interdisciplinary, peer-reviewed journal, publishes manuscripts focused on scientifically based, practical information relevant to all aspects of neurologic rehabilitation. We publish unsolicited papers detailing original work/research that covers the full life span and range of neurological disabilities including stroke, spinal cord injury, traumatic brain injury, neuromuscular disease and other neurological disorders. We also publish thematically organized issues that focus on specific clinical disorders, types of therapy and age groups. Proposals for thematic issues and suggestions for issue editors are welcomed.
