A corrigendum on
Clinical 3-D gait assessment of patients with polyneuropathy associated with hereditary transthyretin amyloidosis
by Vilas-Boas, M. d. C., Rocha, A. P., Cardoso, M. N., Fernandes, J. M., Coelho, T., and Cunha, J. P. S. (2020). Front. Neurol. 11:605282. doi: 10.3389/fneur.2020.605282
In the published article, there was an error in Table 2 as published. The units of the Total body center of mass sway in x-axis (TBCMx) and y-axis (TBCMy) were shown in mm when they should be in cm. The corrected Table 2 and its caption appear below.
TABLE 2
Table 2. Mean ± standard deviation values for each gait parameter and each subject group (1. Healthy Controls – HC; 2. Asymptomatic Carriers – AC; 3. Symptomatic Patients – SP; 3.1 Patients with small-fiber sensory polyneuropathy – SPS – and 3.2 with large-fiber sensory polyneuropathy – SPSL; and 3.3 Patients with motor neuropathy – SMP).
In the published article, there was an error in Table 3 as published. The units of the Total body center of mass sway in x-axis (TBCMx) and y-axis (TBCMy) were shown in mm. The correct unit is cm. The corrected Table 3 and its caption appear below.
TABLE 3
Table 3. Results of the Conover-Iman test (p-value) pairwise comparison between the six groups included in Table 2 (HC, AC, SP, SPS, SPSL and SMP), for each gait parameter.
In the published article, there was an error in Figure 3 as published. The units of the Total body center of mass sway in x-axis were shown in mm in the vertical axis of the plot. The correct unit is cm. The corrected Figure 3 and its caption appear below.
FIGURE 3
Figure 3. Mean and standard deviation for each subject group, for the gait parameters that showed statistically significant differences in the Conover-Iman test (p ≤ 0.05) for all the comparisons, when comparing different pairwise comparison, included in Table III, between the six groups (HC, AC, SP, SPS, SPSL and SMP).
In the published article, there was an error in Supplementary Table S.I. The units of the Total body center of mass sway in x-axis (TBCMx) and y-axis (TBCMy) were shown in mm. The correct unit is cm. The correct material statement appears below.
TABLE S.I
Table S.I. Results of the Conover-Iman test (p-value) for the pairwise comparisons not presented in Table 3 between the six considered groups (HC, AC, SP, SPS, SPSL and SMP), for each gait parameter.
In the published article, there was a mistake on the computation description of one of the assessed parameters (total body center of mass). A correction has been made to “Data Processing,” Paragraph 3:
“For each gait cycle, we computed the 24 spatiotemporal and kinematic gait parameters listed in Table 2 and defined in (15). The total body center of mass (TBCM) sway was computed as the standard deviation of the distance (in the x/y-axis, i.e., medial-lateral and vertical directions) of the total body center of mass (TBCM), in relation to the RGB-D sensor's coordinate system, for all gait cycle frames. For each frame, TBCM's position is the mean position of all body segments' CM, which was obtained according to (21).”
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
