Based on associative learning theories it is hypothesized that pain might be a conditioned response. In people with musculoskeletal pain, the occurrence of movement‐induced pain might be a protective response, influenced by visual cues suggesting that the person is approaching a painful position. This study aimed to determine (1) whether the pain‐free range of motion (ROM) increased and decreased when visual feedback understated or overstated true rotation in people with neck pain and (2) whether this effect was more pronounced if pain was chronic.

在虚拟现实中使用视觉反馈操作来影响非特异性颈部疼痛患者的无痛运动范围

根据联想学习理论，假设疼痛可能是一种条件反应。在肌肉骨骼疼痛的人中，运动引起的疼痛的发生可能是一种保护性反应，受视觉线索的影响，表明该人正在接近痛苦的位置。本研究旨在确定 (1) 当视觉反馈低估或高估颈部疼痛患者的真实旋转时，无痛运动范围 (ROM) 是否会增加和减少，以及 (2) 如果疼痛是慢性的，这种影响是否更明显。
