Table 3.

Bootstrapping results with Welsch’s t-statistic provided for timing analyses and sEMG data obtained during DDK tasks demonstrated clear timing differences between SRC and control groups. Means are reported in syllables per second. Negative mean differences indicate that syllable times for those with a history of concussion were longer than those with no concussion history.

Bootstrapping results with Welsch’s t-statistic provided for timing analyses and sEMG data obtained during DDK tasks demonstrated clear timing differences between SRC and control groups. Means are reported in syllables per second. Negative mean differences indicate that syllable times for those with a history of concussion were longer than those with no concussion history.

TPS = time per syllable; UTPS = unvoiced time per syllable.

A Benjamini-Hochberg (BH) correction was applied where corrected P-values below the BH critical values .047 represents significant results.
