Education research explains how healthcare professional training could be more efficient and effective by integrating simulation technology. Despite its relevance in training medical students, the evidence of its effectiveness in the manual skill training of physiotherapy students remains limited. The aim of this study was to compare the effectiveness of 3-dimensional (3D) images of real objects produced by photogrammetry and traditional 2-dimensional (2D) images when introducing manual therapy skills to undergraduate physiotherapy students via an online course.
In a randomized controlled trial, a group of first-year physiotherapy bachelor honor degree students participated in a 2-hour online course on 3 manual assessment skills: cervical compression, distraction, and flexion-rotation tests. They demonstrated 2 sets of learning materials, including either 3D images of real rotating objects using close-range photogrammetry (experimental group) or traditional 2D images (control group). After their respective training, an Objective Structured Clinical Evaluation procedure was conducted to demonstrate their knowledge about the techniques. A standardized 9-item practical performance test was used as the primary outcome measure for the analyses.
Seventy-seven students participated in the study. The average Objective Structured Clinical Evaluation score for the experimental group (n = 40) was 41.3/50 (±3.9) and the control group (n = 37) was 39.1/50 (±4.5, P = 0.02).
For learning 3 cervical spine assessment skills, this study shows that photogrammetry creates 3D images of real rotating objects that are more effective than 2D images for first-year physiotherapy students.
教育研究通过整合模拟技术解释了如何使医疗保健专业培训更有效率和更有成效。尽管在培训医学生方面具有相关性，但在理疗学生的手工技能培训方面，其有效性的证据仍然有限。本研究的目的是比较通过在线课程向理疗本科学生介绍手动治疗技能时，摄影测量法生成的真实物体的 3 维（3D）图像与传统的 2 维（2D）图像的效果。
在一项随机对照试验中，一组一年级理疗学士荣誉学位学生参加了 2 小时的在线课程，内容涉及 3 项手动评估技能：颈椎压迫、分离和屈伸旋转测试。他们展示了 2 套学习材料，包括使用近景摄影术的真实旋转物体的 3D 图像（实验组）或传统的 2D 图像（对照组）。在各自的培训之后，进行了客观结构化临床评估程序，以展示他们对技术的了解。标准化的 9 项实际操作测试用作主要的分析结果测量。
77 名学生参加了研究。实验组（n = 40）的平均客观结构化临床评估分数为 41.3/50（±3.9），对照组（n = 37）为 39.1/50（±4.5，P = 0.02）。
对于学习 3 项颈椎评估技能，本研究表明，摄影测量法生成的真实旋转物体的 3D 图像比 2D 图像对一年级理疗学生更有效。
