Additionally, the Word Association task (Md = 6.1, W = 559, p = 0.013, r = 0.20) and the Random Number task (Md = 7.65, W = 435, p = 0.054, r = 0.22) demonstrated trends toward reduced cognitive DTC, although these did not reach statistical significance.

While both the affected (t(52) = 2.51, p = 0.015, r = 0.65) and unaffected (t(52) = 2.64, p = 0.011, r = 0.64) lower limbs showed a trend toward improvement, these changes did not reach significance after Bonferroni correction.
