STUDY DESIGN
Feasibility study.
OBJECTIVE
The objective of this study is to explore the feasibility of capturing egocentric (first person) video recordings in the home of individuals with cervical spinal cord injury (SCI) for hand function evaluation.
SETTING
Community-based study in Toronto, Ontario, Canada.
METHODS
Three participants with SCI recorded activities of daily living (ADLs) at home without the presence of a researcher. Information regarding recording characteristics and compliance was obtained as well as structured and semi-structured interviews involving privacy, usefulness, and usability. A video processing algorithm capable of detecting interactions between the hand and objects was applied to the home recordings.
RESULTS
In all, 98.58 ± 1.05% of the obtained footage was usable and included four to eight unique activities over a span of 3-7 days. The interaction detection algorithm yielded an F1 score of 0.75 ± 0.15.
CONCLUSIONS
Capturing ADLs using an egocentric camera in the home environment after SCI is feasible. Considerations regarding privacy, ease of use of the devices, and scheduling of recordings are provided.
研究设计
可行性研究。
目的
本研究旨在探索在颈脊髓损伤（SCI）患者家中采集自我中心（第一人称）视频记录以进行手部功能评估的可行性。
设置
加拿大安大略省多伦多市的基于社区的研究。
方法
3 名 SCI 患者在家中在没有研究人员在场的情况下记录日常生活活动（ADL）。获得有关记录特征和依从性的信息，并进行了涉及隐私、有用性和可用性的结构化和半结构化访谈。应用一种能够检测手与物体之间相互作用的视频处理算法，对家庭记录进行处理。
结果
总共，获得的可用视频片段的 98.58±1.05%，包括 3-7 天内四个至八个独特的活动。交互检测算法的 F1 得分为 0.75±0.15。
结论
在 SCI 后使用自我中心摄像机在家中环境中捕获 ADL 是可行的。提供了有关隐私、设备易用性和记录安排的注意事项。
