The Arm Ability Training improves motor function among stroke and traumatic brain injury patients with mild arm paresis. There is, however, a considerable variability in motor recovery among patients receiving the Arm Ability Training. The study investigated whether psychological variables can explain the variability in motor recovery.
In a sample of 33 patients receiving the Arm Ability Training both motor performance (by use of the standardised arm function test TEMPA) and cognitive functions (attention, perceptual abilities, and learning) as well as depression were assessed before training was commenced. Both univariate correlational analyses and stepwise multiple regression were used to investigate these variables' ability to predict motor improvement (TEMPA difference scores from pre to post test after 3 weeks).
The degree of motor dysfunction of the affected arm explained most (70%) of the variance of motor improvement scores of the standardised arm function test (TEMPA). Psychometric scores showed no or at the most weak associations with motor improvement (explaining at the most 10% of the variance).
Psychological variables had not been critical modifiers of motor recovery among stroke and traumatic brain injury patients with mild arm paresis receiving the Arm Ability Training.
手臂能力训练可改善轻度手臂麻痹的中风和创伤性脑损伤患者的运动功能。然而，接受手臂能力训练的患者在运动恢复方面存在相当大的差异。本研究调查了心理变量是否能够解释运动恢复的差异。
在33名接受手臂能力训练的患者样本中，在训练开始前评估运动表现（通过使用标准化手臂功能测试TEMPA）、认知功能（注意力、感知能力和学习能力）以及抑郁情况。单变量相关分析和逐步多元回归均用于研究这些变量预测运动改善情况的能力（3周后测试前后的TEMPA差异分数）。
患侧手臂的运动功能障碍程度解释了标准化手臂功能测试（TEMPA）运动改善分数的大部分（70%）方差。心理测量分数与运动改善之间无关联或至多存在微弱关联（至多解释10%的方差）。
对于接受手臂能力训练的轻度手臂麻痹的中风和创伤性脑损伤患者，心理变量并非运动恢复的关键调节因素。
