In the article titled “A New Neurocognitive Interpretation of Shoulder Position Sense during Reaching: Unexpected Competence in the Measurement of Extracorporeal Space” [1], there were errors in the following sections.
In the Abstract, the sentence “Results. The shoulder had proprioceptive features that allowed it to memorize a reaching position and reproduce it (error of 1.22 cm to 1.55 cm in healthy subjects)” should be changed to “Results. The shoulder had proprioceptive features that allowed it to memorize a reaching position and reproduce it (error of 0.62 cm ± 0.57 cm in healthy subjects).”
In the Materials and Methods under the “Assessment of Error” subsection, the definition of “spatial error” reported in the Abstract and the correspondence of “spatial error” with “gap in precision” should be added. Therefore, the text reading “Both tests entailed six assessments: three reaching forward and three reaching back. At the end of each evaluation, the examiner noted the error by the subject, defined as the GAP in precision (cm)” should be changed to “Both tests entailed six assessments: three reaching forward and three reaching back. At the end of each evaluation, the examiner noted the error by the subject, defined as the spatial error or GAP in precision (cm).”
In Table , the note “b” refers the value of Student’s -test for independent sample with equal variances not assumed. A note “g” is added for value Student’s -test for paired samples. The corrected table is shown in this paper.
In the Results section, under the “Analysis of the Tests” subsection, the text reading “Between independent Tests 1 and 2 (, reaching total), both groups measured better blindfolded and in the active phase, with average errors of in the HG and in the IG in Test 1 and and , respectively, for active modality and and for passive modality in Test 2” should be corrected to “Between independent Tests 1 and 2 (, reaching total), both groups measured better blindfolded and in the active phase, with average errors of in the HG and in the IG in Test 1 and and , for passive modality, and and for active modality in Test 2.”
In the Discussion, the following two sentences should be changed.
(1) The text reading “Our results indicate that HG and IG subjects estimate an average error concerning the reaching movement that is required of in the HG and in IG (), suggesting that the shoulder has its own proprioceptive ability that is reduced in impingement syndrome” should be corrected to “Our results indicate that HG and IG subjects estimate an RGAP concerning the reaching movement that is required of in the HG and in IG (), suggesting that the shoulder has its own proprioceptive ability that is reduced in impingement syndrome.”
(2) The text reading “With regard to how the proprioceptive sense of the shoulder integrates visual control, our results indicate that subjects perform better in the blindfolded test as in HG as in IG; in particular, the average error was minor in the blindfolded test for reaching forward in Test 2 in the passive modality in both groups” should be corrected to “With regard to how the proprioceptive sense of the shoulder integrates visual control, our results indicate that subjects perform better in the blindfolded passive test as in HG as in IG; in particular, the average error was minor in the blindfolded test for reaching forward in Test 2 in the passive modality in both groups.”
