Tremor is a rhythmic, involuntary oscillatory movement that severely affects some aspects of a patient's daily life. The use of wearable tremor-suppressing orthoses has become an effective, noninvasive treatment method for controlling tremors. This article summarizes recent developments in upper limb tremor suppression orthoses, aiming to provide a foundation for future research. By analyzing the working mechanisms, degrees-of-freedom (DOFs), weight, and tremor suppression effectiveness of various types of orthoses, the following conclusions are drawn: We found that differences in the working mechanism and the number of suppression directions are related to the weight of the device; weight, in turn, is a major factor affecting the comfort of the orthoses; and the combination of the number and weight of the damping direction affects the effect of the damping equipment. Balancing these three factors should be a key focus of future research. Moreover, researchers are placing greater emphasis on the comfort of the wearer during the development of these orthoses.
震颤是一种有节奏的、不由自主的振荡运动，严重影响患者日常生活的某些方面。使用可穿戴式震颤抑制矫形器已成为控制震颤的一种有效、无创的治疗方法。本文总结了上肢震颤抑制矫形器的最新进展，旨在为未来的研究提供基础。通过分析各种类型矫形器的工作机制、自由度（DOF）、重量和震颤抑制效果，得出以下结论：我们发现工作机制和抑制方向数量的差异与设备重量有关；重量反过来又是影响矫形器舒适度的主要因素；阻尼方向的数量和重量的组合会影响阻尼设备的效果。平衡这三个因素应是未来研究的重点。此外，研究人员在这些矫形器的开发过程中更加注重佩戴者的舒适度。
