Approximately 25% of individualsliving with parkinsonian tremor do not respond to traditional treatments. Wearable tremor suppression devices (WTSD) provide an alternative approach, however, tremor in the fingers has not been given as much attention as tremor in the elbow and the wrist. Therefore, the objective of this study is to design a wearable tremor suppression glove that can suppress tremor simultaneously, but independently, in multiple hand joints without restricting the user's voluntary motion.
A WTSD was designed for managing tremor in the index finger metacarpophalangeal (MCP) joint, thumb MCP joint, and the wrist. The prototype was tested and assessed on a participant living with parkinsonian tremor.
The experimental evaluation showed an overall suppression of 73.1%, 80.7%, and 85.5% in resting tremor, 70.2%, 79.5%, and 81% in postural tremor, and 60.0%, 58.7%, and 65.0% in kinetic tremor in the index finger MCP joint, the thumb MCP joint, and the wrist, respectively.
This first assessment of a WTSD for people living with Parkinson's disease provides confirmation of the feasibility of the approach. The next step requires a comprehensive validation on a broader population in order to evaluate the performance of the WTSD.
This study demonstrates the feasibility of using a WTSD to manage hand and finger tremor. The device enriches the field of upper-limb tremor management, as the first WTSD for multiple joints of the hand.
大约 25%的帕金森震颤患者对传统治疗方法没有反应。可穿戴震颤抑制装置 (WTSD) 提供了一种替代方法，然而，手指震颤并没有像肘部和手腕震颤那样受到重视。因此，本研究的目的是设计一种可穿戴的震颤抑制手套，它可以同时但独立地抑制多个手部关节的震颤，而不会限制使用者的自主运动。
设计了一种用于管理食指掌指关节 (MCP)、拇指 MCP 关节和手腕震颤的 WTSD。该原型在一名患有帕金森震颤的参与者身上进行了测试和评估。
实验评估显示，在静止性震颤中，食指 MCP 关节、拇指 MCP 关节和手腕的总体抑制率分别为 73.1%、80.7%和 85.5%；姿势性震颤中分别为 70.2%、79.5%和 81%；运动性震颤中分别为 60.0%、58.7%和 65.0%。
这是对帕金森病患者使用 WTSD 的首次评估，证实了该方法的可行性。下一步需要在更广泛的人群中进行全面验证，以评估 WTSD 的性能。
这项研究证明了使用 WTSD 来管理手部和手指震颤的可行性。该设备丰富了上肢震颤管理领域，是第一个用于手部多个关节的 WTSD。
