Abstract：
OBJECTIVE: This study investigates the learning efficacy for partial weight load before discharge as well as the impact of biofeedback during the learning process.
METHODS: We monitored weight-bearing in 57 patients who had surgery for ankle fractures. Continuous measurements without and with biofeedback were performed in the early postoperative stage in order to, first, assess how well these patients could apply what they have learned before being discharged, and second, to examine the influence of biofeedback.
RESULTS: Using conventional teaching methods, only about one-third of patients (36.8% on the ground and 29.2% on the stairs) were able to maintain a satisfactory load. One-fourth of the patients did not place any weight on their leg, which was shown to be due to excessive pain at the time of the measurement (p < 0.05). A further one-fourth loaded inadequately low, while the remainder loaded excessively. Patients benefited significantly from the activation of audio-visual biofeedback in real time. As a result, loads in a target zone between 15 and 30 kg could be significantly increased (p < 0.05).
CONCLUSIONS: We conclude that the majority of ankle fracture patients were unable to learn partial weight bearing in the early postoperative stage using traditional techniques. Additionally, each patient\'s ability to carry out a given loading varied. Using an audio-visual real-time biofeedback modality led to significantly improved performance. These findings support the proposed utility of audiovisual feedback in early rehabilitation. With the use of outpatient real-time biofeedback systems, therapists will be able to respond specifically to the needs of each individual patient.

摘要：
目的：本研究调查了出院前部分负重的学习效果以及学习过程中生物反馈的影响。
方法：我们监测了57例踝关节骨折手术患者的负重情况。在术后早期进行无生物反馈和有生物反馈的连续测量，以便，首先,评估这些患者在出院前如何运用所学知识，第二,检查生物反馈的影响。
结果：使用常规教学方法，只有约三分之一的患者（地面上的36.8％和楼梯上的29.2％）能够保持令人满意的负荷。四分之一的患者没有在腿上放置任何重量，这被证明是由于在测量时过度疼痛(p<0.05)。还有四分之一的负载不足，而其余的加载过度。患者从实时激活视听生物反馈中受益匪浅。因此,在15和30公斤之间的目标区域的负荷可以显着增加（p<0.05）。
结论：我们得出的结论是，大多数踝关节骨折患者使用传统技术在术后早期无法学习部分负重。此外,每个病人执行给定负荷的能力各不相同。使用视听实时生物反馈模态导致显著提高的性能。这些发现支持视听反馈在早期康复中的拟议效用。随着门诊实时生物反馈系统的使用，治疗师将能够对每个患者的需求做出具体反应。
