基于音乐生物反馈的帕金森患者步态康复校正产品设计研究

Design of a Gait Rehabilitation Product Based on Musical Biofeedback for Patients with Parkinson's Disease

目的为帕金森患者的生理步态康复和心理状态调适提供音乐生物反馈的方法和矫正系统。方法根据音乐生物反馈原理,创建能够将音乐刺激信号转化为调节步态的听觉信号,以听觉通道感官调节步行状态。同时,选用偏好音乐材料,为帕金森患者的步态康复过程提供外在辅助和内在驱动。从帕金森病症的疾病概况和相关研究概况入手,为其提供生理心理学双通道的治疗策略,并以此为指导完成硬件原型和软件应用的设计与开发,最后通过结构化的利克特量表为该矫正系统提供了一个包含合理性、满意度和市场情况的评价分析模型。结果构建了一个新型的基于音乐生物反馈的帕金森患者步态康复矫正系统设计,通过新颖的交互形式和听觉感官刺激来激发帕金森患者调节步幅、步态的主动行为能力。结论通过评估量化设计效应后发现:该系统可以改善帕金森患者的肌强直和姿势平衡障碍等症状,有效降低PD患者疾病相关负性情绪的诱发率,并大大提高患者的主动康复意识和康复积极性,为帕金森病的康复提供了一个行之有效的新方案。

The work aims to provide musical biofeedback method and correction system to regulate physiological gait rehabilitation and psychological state of patients with Parkinson's disease.According to the musical biofeedback princi-ple,the auditory signals that could transform musical stimulation signals into gait adjustment were created to adjust the gait with auditory channels.At the same time,the preferred musical materials were selected to provide external assistance and internal drive for gait rehabilitation of patients with Parkinson's disease.From the general situation of Parkinson's disease and related research,a dual-channel treatment strategy covering physiology and psychology was provided,and the design and development of hardware prototype and software application were completed under this guidance.Finally,an evaluation and analysis model including rationality,satisfaction and market situation was provided for the correction sys-tem through the structured Lickert scale.A gait rehabilitation correction system based on musical biofeedback for patients with Parkinson's disease was created,stimulating the active behavioral ability of patients with Parkinson's disease in ad-justing stride and gait through novel interactive forms and auditory sensory stimulation.Quantitative assessment reveals that for patients with Parkinson's disease,the system mitigates symptoms such as myotonicity and postural balance disor-ders,reduces negative emotions during different disease stages,and improves rehabilitation awareness and motivation,offering an effective approach to rehabilitation of patients with Parkinson's disease.
