Table 1 Sensitivity analyses of foot-stomping metrics pre- vs post-neurofeedback. Wilcoxon signed-rank tests were conducted for (i) all participants (N=10), (ii) responders only (N=8), and after excluding non-responders individually (P01 or P09, N=9). Effect directions were consistent across analyses. All metrics remained significant when excluding P01, whereas exclusion of P09 led to a loss of significance for acceleration magnitude (p = 0.074). The reduction in significance in smaller subsets reflects decreased statistical power rather than reversal of the observed effects.
Metric | All (N=10) | Responders (N=8) | Excl. P01 (N=9) | Excl. P09 (N=9) |
|---|---|---|---|---|
Steps per second | +5.71%; W = 3.0, p = 0.010** | W = 3.0, p = 0.039* | W = 4.0, p = 0.020* | W = 4.0, p = 0.020* |
Mean peak velocity | +36.07%; W = 0.0, p = 0.002** | W = 0.0, p = 0.008** | W = 1.0, p = 0.004** | W = 1.0, p = 0.004** |
Step interval | –4.54%; W = 5.0, p = 0.020* | W = 5.0, p = 0.078 | W = 7.0, p = 0.039* | W = 7.0, p = 0.039* |
Acceleration magnitude | +14.51%; W = 7.0, p = 0.037* | W = 5.0, p = 0.078 | W = 8.0, p = 0.039* | W = 10.0, p = 0.074 |
