基于肌电图 (EMG) 的视听生物反馈系统是在研究环境中开发和测试的，用于训练脑瘫 (CP) 等患者群体的神经肌肉控制，但存在固有的实施障碍，可能会限制其转化为临床实践。本研究的目的是设计和验证一种替代的基于足底压力的生物反馈系统，用于改善 CP 患者行走过程中踝关节跖屈肌的募集。招募了 8 名脑瘫患者（11-18 岁）来测试步行时基于肌电图和足底压力的生物反馈系统。比较了两个系统之间以及相对于基线行走的踝关节跖屈肌募集、踝关节共同收缩和下肢运动学。相对于基线步行，两种生物反馈系统均使比目鱼肌平均（43-58％，p< 0.05）、腓肠肌内侧激活平均值（68-70％，p< 0.05）和峰值（71-82％，p< 0.05）显着增加，两个系统之间没有差异，并且所有主要结果变量都具有很强的相关性（R = 0.89–0.94）。仅使用基于 EMG 的系统时，踝关节协同收缩相对于基线显着增加（52%，p = 0.03）。这些发现支持未来通过这种简单、低成本的生物反馈方式进行功能训练的研究。在线版本包含可在 10.1186/s12984-022-01119-y 获取的补充材料。
Electromyography (EMG)-based audiovisual biofeedback systems, developed and tested in research settings to train neuromuscular control in patient populations such as cerebral palsy (CP), have inherent implementation obstacles that may limit their translation to clinical practice. The purpose of this study was to design and validate an alternative, plantar pressure-based biofeedback system for improving ankle plantar flexor recruitment during walking in individuals with CP. Eight individuals with CP (11–18 years old) were recruited to test both an EMG-based and a plantar pressure-based biofeedback system while walking. Ankle plantar flexor muscle recruitment, co-contraction at the ankle, and lower limb kinematics were compared between the two systems and relative to baseline walking. Relative to baseline walking, both biofeedback systems yielded significant increases in mean soleus (43–58%, p < 0.05), and mean (68–70%, p < 0.05) and peak (71–82%, p < 0.05) medial gastrocnemius activation, with no differences between the two systems and strong relationships for all primary outcome variables (R = 0.89–0.94). Ankle co-contraction significantly increased relative to baseline only with the EMG-based system (52%, p = 0.03). These findings support future research on functional training with this simple, low-cost biofeedback modality.
