Abstract

This work reports the use of a head-motion monitoring system to record patient head movements while completing in-home exercises for vestibular rehabilitation therapy. Based upon a dual-axis gyroscope (yaw and pitch, ± 500-degrees/sec maximum), angular head rotations were measured and stored via an on-board memory card. The system enabled the clinician to document exercises at home. Several measurements were recorded in one patient with unilateral vestibular hypofunction: The total time of exercise for the week (118 minutes) was documented and compared with expected weekly exercise time (140 minutes). For gaze stabilization exercises, execution time of 60 sec was expected, and observed times ranged from 75-100 sec. An absence of rest periods between each exercise instead of the recommended one minute rest period was observed. Maximum yaw head velocities from approximately 100-350 degrees/sec were detected. A second subject provided feedback concerning the ease of use of the HAMMS device. This pilot study demonstrates, for the first time, the capability to capture the head-motion "signature" of a patient while completing vestibular rehabilitation exercises in the home and to extract exercise regime parameters and monitor patient adherence. This emerging technology has the potential to greatly improve rehabilitation outcomes for individuals completing in-home gaze stabilization exercises.
一种用于家庭前庭康复治疗的头部运动监测系统原型。
这项工作报告了使用头部运动监测系统来记录患者在完成前庭康复治疗的家庭练习时的头部运动。基于双轴陀螺仪(偏航和俯仰,±500度/秒最大值),测量角头部旋转并通过板载存储卡存储。该系统使临床医生能够在家中记录锻炼情况。记录了一名单侧前庭功能减退患者的几项测量:记录了一周的总运动时间(118分钟),并与预期的每周运动时间(140分钟)进行了比较。对于凝视稳定练习,预计执行时间为60秒,观察时间范围为75-100秒。每次练习之间没有休息时间,而不是建议的一分钟休息时间。最大偏航头速度约为100-350度/秒。第二名受试者提供了关于HAMMS设备使用的易用性的反馈。这项初步研究首次展示了在家中完成前庭康复练习时捕捉患者头部运动“特征”的能力,并提取运动方案参数并监测患者的依从性。这项新兴技术有潜力极大地改善个人完成在家凝视稳定练习的康复结果。
