Results of the regression analyses between balance confidence and the quiet standing, walking, and reactive stepping outcome measures. The measures in the left-hand column represent the dependent variables in the regression equation. The Holm-Bonferroni corrected alpha was 0.004.

Continuous measures Predictor variable Mean (SD) Parameter estimate Partial R2 p-value

Cable load (% body weight) 8.57 (2.91) −0.040 0.078 0.061
Binary measures Predictor variable Number of participants (%) Increment Odds ratio [95% CI] p-value
Reactive stepping (N=47)
Grasp reactions ABC score Grasp: 5 (10.6) 10.0 0.66 [0.39, 1.13] 0.13

ABC: Activities-Specific Balance Confidence Scale; AP: antero-posterior; CI: confidence interval; ML: medio-lateral; SD: standard deviation.
