Plantar pressure refers to the interfacial contact pressure between the foot and the supporting surface during daily locomotor activities. Information derived from plantar pressure measures is essential in gait and posture research for diagnosing patho-mechanics associated with the musculoskeletal diseases. In particular, it is compulsory to reduce the abnormally high plantar pressure in people with diabetes for the prevention and treatment of foot ulcerations in this population. In this study, a portable biofeedback-based gait training device is developed to advocate able-bodied subjects to adopt different movement patterns in walking to manipulate the plantar pressure distribution under the foot. Through the simultaneous detection of the plantar pressure pattern and the kinematics of the lower extremity joints, it was revealed that the unloading effects for the plantar site in particular to the lateral forefoot subareas were more abundant through biofeedback-assisted gait alterations than the self-awareness control for gait adjustment. In addition, the corresponding relationship between joint coordination and pressure redistribution pattern was obtained, which could potentially be used in gait retraining interventions to correct abnormal plantar pressure patterns in people with diabetes.

评估不同步行策略对便携式基于生物反馈的步态训练设备触发的足底压力分布的潜在影响

足底压力是指在日常运动活动中足部与支撑面之间的界面接触压力。来自足底压力测量的信息对于诊断与肌肉骨骼疾病相关的病理力学的步态和姿势研究至关重要。特别是，必须降低糖尿病患者异常高的足底压力，以预防和治疗该人群的足部溃疡。在这项研究中，开发了一种基于生物反馈的便携式步态训练装置，以倡导身体健全的受试者在步行时采用不同的运动模式来控制足底压力分布。通过同时检测足底压力模式和下肢关节运动学，结果表明，通过生物反馈辅助步态改变对足底部位特别是前足外侧亚区的卸载效果比用于步态调整的自我意识控制更丰富。此外，获得了关节协调和压力再分布模式之间的对应关系，这可能用于步态再训练干预，以纠正糖尿病患者的异常足底压力模式。
