Technologies for low-cost mobile sensorimotor assessment following concussion

该提案旨在开发一种低成本的移动的系统，用于测量和评估脑震荡后的感觉运动性能，整合以下评估模块：i）参与头部和眼睛运动协调的前庭眼反射（VOR），ii）站立平衡，iii）双手协调，以及iv）即时空间背景的情境意识。该提案旨在开发使用移动的平台在脑震荡筛查期间测量头部姿势和注视方向、上肢运动学、姿势摇摆和意识的方法。为了向患者及其物理治疗师提供测量和性能反馈，将设计集成评估模块的用户界面。所提出的系统的可用性和技术性能将通过实验室级运动捕捉和临床环境进行验证。

This proposal seeks to develop a low-cost mobile system for the measurement and assessment of sensorimotor performance following concussion, integrating assessment modules of: i) vestibular-ocular reflex (VOR) involved in the coordination of head and eye movements, ii) standing balance, iii) bimanual coordination, and iv) situational awareness of the immediate spatial context. The proposal aims to develop methods for measuring head pose and gaze direction, upper limb kinematics, postural sway, and awareness during concussion screening using a mobile platform. To provide measurement and performance feedback to the patient and their physiotherapist, a user interface integrating assessment modules will be designed. Usability and technical performance of the proposed system will be validated experimentally with laboratory grade motion capture and in clinical settings.
