Effective treatment of longstanding Complex Regional Pain Syndrome (CRPS) is a challenge, as causal mechanisms remain elusive. People with CRPS frequently report distorted subjective perceptions of their affected limb. Evidence of pain reduction when the affected limb is visually altered in size suggests that visual illusions used to target central processing could restore coherence of this disrupted limb representation. We hypothesized that using virtual reality that alters hand image to match the patient's desired hand appearance would improve body perception disturbance and pain. Also, repeated exposure would maintain any therapeutic effect.

视觉错觉调节复杂区域疼痛综合征的身体知觉障碍和疼痛：一项随机试验

有效治疗长期存在的复杂区域疼痛综合征 (CRPS) 是一项挑战，因为因果机制仍然难以捉摸。患有 CRPS 的人经常报告对其受影响肢体的主观感知扭曲。当受影响的肢体在视觉上改变大小时疼痛减轻的证据表明，用于针对中央处理的视觉错觉可以恢复这种被破坏的肢体表现的连贯性。我们假设使用虚拟现实来改变手部图像以匹配患者所需的手部外观将改善身体感知障碍和疼痛。此外，反复接触将保持任何治疗效果。
