To investigate the responsiveness and cross-sectional and longitudinal validity of the Motor Activity Log (MAL) in the subacute phase after stroke.
Data were collected pre-intervention, post-intervention, and at 3-month follow-up evaluations from 30 patients with stroke participating in a randomized trial of forced use. Assessments included MAL, the Fugl-Meyer test, the 16-hole peg test, grip strength, the Action Research Arm Test, and the Motor Assessment Scale. Measurements of responsiveness were effect size, standardized response mean (SRM), and responsiveness ratio (RR). Relationships between the MAL and the other measures were determined with Spearman correlations.
The MAL is responsive to change, with effect size, SRM, and RR>1.0 at the 3-month follow-up, and SRM and RR>1.0 at post-intervention. Correlations at the separate test occasions between MAL and the other measures were mostly close to 0.50, which shows fair to moderate construct validity. Correlations between changes in MAL and in the other measures were weaker than cross-sectional relationships.
The MAL is a responsive measure of daily hand use in patients participating in rehabilitation in the subacute phase after stroke. Correlations of construct validity indicate that daily hand use may need to be measured separately from body function and activity capacity, in line with the underlying constructs of International Classification of Functioning, Disability and Health. To strengthen our findings, they should be repeated in larger samples of patients.
研究运动活动日志（MAL）在中风后亚急性期的反应性以及横断和纵向有效性。
30 名参与强制性使用随机试验的中风患者在干预前、干预后和 3 个月随访评估时收集数据。评估包括 MAL、Fugl-Meyer 测试、16 孔钉测试、握力、动作研究臂测试和运动评估量表。反应性的测量包括效应大小、标准化反应均值（SRM）和反应比（RR）。用 Spearman 相关系数确定 MAL 与其他测量值之间的关系。
MAL 对变化敏感，在 3 个月随访时具有>1.0 的效应大小、SRM 和 RR，在干预后具有>1.0 的 SRM 和 RR。MAL 与其他测量值在单独测试时的相关性接近 0.50，这表明具有良好到中等的结构有效性。MAL 与其他测量值的变化之间的相关性弱于横断相关性。
MAL 是中风后康复亚急性期患者日常手部使用的敏感测量工具。结构有效性的相关性表明，日常手部使用可能需要与身体功能和活动能力分开测量，与国际功能、残疾和健康分类的潜在结构一致。为了加强我们的发现，应该在更大的患者样本中重复这些发现。
