To test the efficacy of the arm ability training (AAT) on a sample of patients with central arm paresis after traumatic brain injury (TBI) or stroke.
Single-blind, randomized, controlled trial.
Inpatient rehabilitation center.
Consecutive sample of 74 patients of whom 60 (45 with stroke, 15 with TBI) completed the study; 37 patients received a 1-year follow-up.
Daily AAT with (n = 20) or without (n = 20) knowledge of results, or no AAT (n = 20) during a 3-week intervention period.
Summary time scores of the Test Evaluant les Membres superieurs des Personnes Agees (TEMPA)-a test of upper extremity function with daily function-like activities (focal disability)-and kinematic analysis of aimed movements.
Patients with AAT realized superior improvement as compared with controls. Mean improvement in the time needed to perform (1) all TEMPA tasks was 41.4 versus 12.8 seconds (p =.0012); (2) unilateral TEMPA tasks, 16.5 versus 4.2 seconds (p =.0036); and (3) the ballistic component of aimed movements, 96 versus 20ms (p =.0115). Knowledge of result did not substantially modify these effects. A functional benefit existed at 1-year follow-up.
The AAT reduces focal disability among stroke and TBI patients with mild central arm paresis.
对创伤性脑损伤（TBI）或中风后出现中枢性手臂麻痹的患者样本进行手臂能力训练（AAT）效果测试。
单盲、随机、对照试验。
住院康复中心。
连续纳入74例患者，其中60例（45例中风患者，15例TBI患者）完成研究；37例患者接受了为期1年的随访。
在为期3周的干预期内，20例患者进行有结果反馈的每日AAT训练，20例患者进行无结果反馈的每日AAT训练，20例患者不进行AAT训练。
老年上肢功能测试（TEMPA）的总时间得分——一项针对上肢功能及日常功能样活动（局灶性残疾）的测试，以及目标动作的运动学分析。
与对照组相比，接受AAT训练的患者改善更显著。执行以下任务所需时间的平均改善情况为：（1）所有TEMPA任务，41.4秒对12.8秒（p = 0.0012）；（2）单侧TEMPA任务，16.5秒对4.2秒（p = 0.0036）；（3）目标动作的弹道部分，96毫秒对20毫秒（p = 0.0115）。结果反馈并未显著改变这些效果。在1年随访时存在功能获益。
AAT可减轻轻度中枢性手臂麻痹的中风和TBI患者的局灶性残疾。
