Knee osteoarthritis is among the most prevalent chronic diseases. Total knee arthroplasty is a common solution that effectively addresses the continued structural degeneration of the articular cartilage. However, effective physical therapy is critical for recovery. Despite participating in physical therapy, many patients fail to recover. This study investigated the potential efficacy of a behaviorally informed approach to surface electromyographic biofeedback following total knee arthroplasty relative to the clinical standard, neuromuscular electrical stimulation. The surface electromyographic biofeedback procedure incorporated improved techniques for establishing a baseline and individualized and adjusting criteria for feedback. The findings suggest some advantages for surface electromyographic biofeedback over neuromuscular electrical stimulation in quadriceps strength, range of motion, functional recovery, and quality of life. Behaviorally informed surface electromyographic biofeedback holds promise for total knee arthroplasty recovery and these data suggest considerable room for collaboration between behavior analysts and physical therapists.

基于表面肌电图的生物反馈可以促进全膝关节置换术的恢复

膝骨关节炎是最常见的慢性疾病之一。全膝关节置换术是有效解决关节软骨持续结构退化的常见解决方案。然而，有效的物理治疗对于康复至关重要。尽管参加了物理治疗，许多患者仍未能康复。这项研究调查了全膝关节置换术后表面肌电生物反馈行为知情方法相对于临床标准神经肌肉电刺激的潜在功效。表面肌电生物反馈程序结合了用于建立基线和个性化和调整反馈标准的改进技术。研究结果表明，表面肌电生物反馈在股四头肌力量、运动范围、功能恢复和生活质量方面优于神经肌肉电刺激。行为知情的表面肌电生物反馈有望实现全膝关节置换术的恢复，这些数据表明行为分析师和物理治疗师之间有很大的合作空间。
