The effect of bodily illusions on clinical pain: a systematic review and meta-analysis.

摘要: This systematic review and meta-analysis critically examined the evidence for bodily illusions to modulate pain. Six databases were searched; 2 independent reviewers completed study inclusion, risk of bias assessment, data extraction. Included studies evaluated effect a illusion on pain, comparing results with control group/condition. Of 2213 identified, 20 (21 experiments) included. Risk was high due selection lack blinding. Consistent pain decrease found existence body part (myoelectric/Sauerbruch prosthesis vs cosmetic/no prosthesis; standardized mean differences = -1.84, 95% CI -2.67 -1.00) 4 6 weeks mirror therapy (standardized -1.11, -1.66 -0.56). Bodily resizing had consistent modulation (in direction hypothesized). Pooled no 1 session or incongruent movement (except comparisons congruent mirrored movements: significantly increased odds experiencing pain). Conflicting virtual walking (both active inactive comparisons). Single suggest evoked by noxious stimuli, embodiment illusions, but significant synchronous stroking in nonresponders traditional therapy. There is limited that can alter some namely therapy, resizing, use functional prostheses show therapeutic promise.
