Previous research has shown that measuring the size and content of patients' drawings of their illness can reveal their perceptions and predict recovery. This study aimed to assess the usefulness of analyzing kinematic features of drawings.
A pilot observational study was conducted with 15 patients who had been hospitalized with a stroke 8 to 11 months previously. They were asked to draw a picture of what they thought had happened to their brain and describe the drawing using an electronic inking pen and digitizing tablet. Analysis of kinematic data (time to draw/write, drawing/writing speed, and pen pressure) was conducted using MovAlyzeR® software. Evaluations of physical functioning, quality of life, illness perceptions, and emotional well-being were administered, and correlations with kinematic measures assessed.
Stronger pen pressure was associated with perceptions of greater control over the stroke. Faster drawing was correlated with greater worry about a recurrent stroke and the perception that the effects of the stroke would last longer. Needing more time to write was associated with perceptions of fewer consequences of the stroke. No associations between kinematic measures and indicators of stroke severity, physical, or emotional well-being were shown.
Kinematic measures of stroke patients' drawings of their brain and comments were associated with illness perceptions and not measures of physical or emotional health status. The addition of kinematic analysis may add further utility to the assessment of patients' drawings of their illness. More studies need to be performed with larger sample sizes and other patient groups.
先前的研究表明，测量患者对疾病的绘图的大小和内容可以揭示他们的认知，并预测康复情况。本研究旨在评估分析绘图运动特征的有用性。
对 15 名曾因中风住院 8 至 11 个月的患者进行了一项试点观察性研究。他们被要求画一幅他们认为大脑发生了什么的画，并使用电子绘图笔和数字化板描述这幅画。使用 MovAlyzeR®软件对运动学数据（绘图/写字时间、绘图/写字速度和笔压）进行分析。对身体功能、生活质量、疾病认知和情绪健康进行评估，并评估与运动学测量的相关性。
更强的笔压与对中风控制感的认知有关。更快的绘图速度与对中风复发的担忧以及对中风影响持续时间更长的认知有关。书写时间更长与对中风后果的认知较少有关。运动学测量与中风严重程度、身体或情绪健康的指标之间没有关联。
中风患者对大脑的绘图及其评论的运动学测量与疾病认知有关，而与身体或情绪健康状况无关。运动学分析的加入可能会进一步提高对患者疾病绘图评估的效用。需要进行更多具有更大样本量和其他患者群体的研究。
