生物反馈已经被有效地实施以改善步态期间关节负荷的调节和分布，然而，不能通过改变负荷模式来有效地协调下肢运动可能会增加病理应力和损伤和有害关节变化的风险。本研究检查了提示下肢负荷增加或减少对步态期间肢体间和肢体内关节协调的影响，在此应用于12名前交叉韧带重建后的患者，包括三种负荷条件（对照、高负荷和低负荷）。视觉生物反馈通过测力跑步机呈现在屏幕上，并根据两侧步幅到步幅的峰值垂直地面反作用力规定了有针对性的变化。通过对每种情况的离散相对相位和交叉递归量化分析，评估了踝关节、髋关节和膝关节对之间的协调动力学模式和稳定性。高负荷和低负荷改变了肢体内协调的模式和稳定性;低负荷导致协调稳定性降低（比对照条件大20°），高负荷导致更紧密耦合的协调模式（更高的%CDET）。通过对运动控制的深思熟虑，生物反馈可以用于靶向导致长期有害关节适应的机制。
Biofeedback has been effectively implemented to improve the mediation and distribution of joint loads during gait, however, the inability to effectively coordinate lower limb movement by altering loading patterns may increase pathological stress and risk of injury and deleterious joint changes. This study examined the influence cueing an increase or decrease in lower extremity loading has on inter- and intralimb joint coordination during gait, applied herein for 12 persons following anterior cruciate ligament reconstruction across three loading conditions (control, high, and low). Visual biofeedback was presented on a screen via a force-measuring treadmill with targeted changes prescribed based on stride-to-stride peak vertical ground reaction forces bilaterally. The pattern and stability of coordination dynamics among each of the ankle, hip and knee joint pairs were assessed via discrete relative phase and cross-recurrence quantification analyses for each condition. High and low loading altered the pattern and stability of intralimb coordination; low loading led to decreased coordination stability (20° greater than control condition) and high loading resulted in a more tightly coupled coordination pattern (higher %CDET). With thoughtful consideration for movement control, biofeedback can be used to target mechanisms leading to long-term deleterious joint adaptations.
