Table 2.
Results of Peripheral Nerve Stimulation (PNS) before and after WBV. Neuromuscular data are normalized to t1±standard deviations (in %). Joint excursions are demonstrated in (°) with the neutral positions being defined as 90° in the ankle and 0° in the knee joint (extension). Significant differences in pairwise comparison to t1 (p<0.05) are marked with *; significant adaptations over time are demonstrated by rmANOVA with P<0.05 and intraclass correlation coefficients (ICCs) are illustrated in the last column.
