Forrest GF, Lorenz DJ, Hutchinson K, VanHiel LR, Basso DM, Datta S, Sisto SA, Harkema SJ. Ambulation and balance outcomes measure different aspects of recovery in individuals with chronic, incomplete spinal cord injury. Arch Phys Med Rehabil 2012;93:1553-64, Fig 1, Fig 3, Fig 4 were incomplete as published. We sincerely regret these errors.
Fig 1Scatterplots depicting relationships among assessments of 6MW, 10MW, BBS, and MFR. Plots in the first and third rows show relationships in performance on the measures, and plots in the second and fourth rows show relationships among evaluation-to-evaluation changes in the measures. (A) 10MW vs 6MW. (B) BBS vs 6MW. (C) BBS vs 10MW. (D) Change in 10MW vs change in 6MW. (E) Change in BBS vs change in 6MW. (F) Change in BBS vs change in 10MW. (G) MFR vs BBS. (H) MFR vs 6MW. (I) MFR vs 10MW. (J) Change in MFR vs change in BBS. (K) Change in MFR vs change in 6MW. (L) Change in MFR vs change in 10MW. Measurements of phase 1 patients are in red, phase 2 in green, and phase 3 in blue. Abbreviations: 6MW, 6-minute walk; 10MW, 10-meter walk; BBS, Berg Balance Scale; MFR, Modified Functional Reach.
Fig 3Scatterplots of 6MW test speed and 10MW test speed. (A) 6MW speeds against 10MW speeds. (B) Difference between 6MW and 10MW speeds against 10MW speeds. (C) Prediction error (residuals) from a linear mixed-effects model predicting 6MW speeds with 10MW speeds. Abbreviations: 6MW, 6-minute walk; 10MW, 10-meter walk.
Fig 4Scatterplots of the enrollment (initial device) and current-use device assessments of the 6MW and 10MW. Top row shows initial device vs current device for the 6MW (A) and 10MW (B). Middle row shows residuals from the line of best fit for the 6MW (C) and 10MW (D). Bottom row shows the current device-initial device difference against the initial device distance for the 6MW (E) and speed for the 10MW (F). Abbreviations: 6MW, 6-minute walk; 10MW, 10-meter walk.
