To assess recovery of grip strength during the first year post-stroke.
Exploratory study on a subsample of patients participating in the Norwegian Constraint-Induced Movement Therapy trial.
Eleven patients (mean age 59.1 years; 3 women) with mild to moderate stroke were recruited 7-29 days post-stroke.
An electronic dynamometer (Biometrics Ltd, Gwent, UK, 2006) was used to assess maximum grip force in 5 hand positions, rate of force development and sustainability of grip force. Similar assessments were performed to assess pinch strength. The participants were assessed 5 times during a 1-year period.
Grip force in the affected hand increased in all handle positions during the 1-year follow-up, mostly during the first 6 months. At 2 and 4 weeks, rate of force development was less than half, and relative sustainability of grip force showed 20-30% greater deficit than for the non-affected hand. The affected hand approached the values of the non-affected hand after 6 months with little further progress until 1-year follow-up.
Grip strength in the affected hand improved considerably in the first year post-stroke. Patterns of improvement were similar across tests, i.e. rapid during the first weeks, slower until 6 months, and minimal 6-12 months post-stroke.
评估中风后第一年握力的恢复情况。
挪威强制性运动疗法试验的患者亚组的探索性研究。
11 名（平均年龄 59.1 岁；3 名女性）轻度至中度中风患者，在中风后 7-29 天内招募。
使用电子测力计（Biometrics Ltd，Gwent，UK，2006）评估 5 种手部位置的最大握力、力量发展速度和握力可持续性。类似的评估用于评估捏力。参与者在 1 年内进行了 5 次评估。
在 1 年的随访中，患手在所有手柄位置的握力均增加，主要是在前 6 个月。在 2 周和 4 周时，力量发展速度不到一半，相对握力的可持续性比非患手低 20-30%。患手在 6 个月后接近非患手的数值，直到 1 年随访时几乎没有进一步进展。
中风后患手的握力在第一年有了显著改善。各项测试的改善模式相似，即最初几周快速，6 个月前缓慢，6-12 个月后最小。
