Lower back disorders (LBDs) affect a large proportion of the population, and treatment for LBDs have been shifting toward individualized, patient-centered approaches. LBDs are typically associated with poor proprioception. Therefore, there has been a recent uptake in the utilization of wearable sensors that can administer biofeedback in various industrial, clinical, and performance-based settings to improve lumbar proprioception. The aim of this study was to investigate whether wearable sensor-derived acute auditory biofeedback can be used to improve measures of gross lumbar proprioception. To assess this, healthy participants completed an active target repositioning protocol, followed by a training period where lumbar-spine posture referenced auditory feedback was provided for select targets. Target re-matching abilities were captured before and after acute auditory biofeedback training to extract measures related to accuracy and precision across spine flexion targets (i.e., 20%, 40%, 60%, 80% maximum). Results suggest a heterogenous response to proprioceptive training whereby certain individuals and spine flexion targets experienced positive effects (i.e., improved accuracy and precision). Specifically, results suggest that mid-range flexion targets (i.e., 40-60% maximum flexion) benefited most from the acute auditory feedback training. Further, individuals with poorer repositioning abilities in the pre-training assessment showed the greatest improvements from the auditory feedback training.
下背部疾病（LBDs）影响了很大一部分人群，LBD 的治疗方法已经转向个体化、以患者为中心的方法。LBDs 通常与较差的本体感觉有关。因此，最近越来越多地使用可在各种工业、临床和基于性能的环境中提供生物反馈的可穿戴传感器来改善腰椎本体感觉。本研究旨在探讨可穿戴传感器衍生的急性听觉生物反馈是否可用于改善腰椎本体感觉的总体测量。为了评估这一点，健康参与者完成了主动目标重新定位协议，然后是一个训练期，在此期间，为选定的目标提供腰椎姿势参考听觉反馈。在急性听觉生物反馈训练前后捕捉目标重新匹配能力，以提取与脊柱弯曲目标（即 20%、40%、60%、80%最大）相关的准确性和精度的测量值。结果表明，对本体感觉训练存在异质反应，某些个体和脊柱弯曲目标表现出积极的效果（即准确性和精度提高）。具体来说，结果表明，中范围弯曲目标（即 40-60%最大弯曲）最受益于急性听觉反馈训练。此外，在预训练评估中重新定位能力较差的个体从听觉反馈训练中获得了最大的改善。
