Erratum

        A table with incorrect information was published in Peltz E, Seifert F, Lanz S, Müller R, Maihöfner C: Impaired hand size estimation in CRPS. J Pain 12:1095-1101, 2011.
        The corrected data for Table 1 appears below:
        Table 1Hyperalgesia and TPDTs
        A) Hyperalgesia and Pain Scores (Mann-Whitney U Test)
        PresentAbsentP Value
        PRI31.9 ± 13.817.3 ± 12.7P < .01
        NRS33.7 ± 13.244.7 ± 17.7ns
        B) Two-Point-Discrimination Thresholds (mm; Mann-Whitney U Test, Except for Comparison Between Affected and Unaffected Side, Where a Wilcoxon Signed-Rank Test was Used)

        Controls right2.11 ± .26P < .05ns
        C) Correlation Analysis of TPDT and Pain
        McGill PRIr = −.06ns
        NRSr = .03ns
        D) TPDTs (mm) and Clinical Signs (Mann-Whitney U Test)
        PresentAbsentP Value
        Hyperalgesia1.39 ± .811.57 ± .86ns
        Allodynia1.42 ± .851.51 ± .83ns
        Edema1.31 ± .841.95 ± .61P < .05
        Abbreviation: ns, nonsignificant.
        The corrected information does not affect the primary findings presented in the original article. However, the correlation between McGill PRI and TPDT is not significant in the corrected table. Therefore, the following correction should be made in the Results section under the heading “TPDTs”:
        “There was no correlation between TPDTs of the affected extremity and McGill PRI or spontaneous pain ratings (Table 1c).”
        The second to last sentence in the second paragraph of the discussion should read:
        “As described previously,18 TPDTs were not related to the rated pain intensity itself.”
        Finally, in the Methods section, the sentence describing the 2-point discrimination paradigm should read:
        “In a randomized order, pairs of needles with an interspace ranging from 1.0 to 5.0 mm (diameter 200 μm, .4-mm steps) were applied to the skin.”
        The authors apologize for any inconvenience this may have caused.

        • Impaired Hand Size Estimation in CRPS
          The Journal of PainVol. 12Issue 10
          • Preview
            A triad of clinical symptoms, ie, autonomic, motor and sensory dysfunctions, characterizes complex regional pain syndromes (CRPS). Sensory dysfunction comprises sensory loss or spontaneous and stimulus-evoked pain. Furthermore, a disturbance in the body schema may occur. In the present study, patients with CRPS of the upper extremity and healthy controls estimated their hand sizes on the basis of expanded or compressed schematic drawings of hands. In patients with CRPS we found an impairment in accurate hand size estimation; patients estimated their own CRPS-affected hand to be larger than it actually was when measured objectively.
