From: Cortical correlates in upright dynamic and static balance in the elderly
(a) Muscle activity as measured using EMG sensors. b) RMS EMG results. Median values across the elderly (in green) and the younger adults (in pink) of the RMS values for each muscle (ordered in column): Erector Spinae (ES), Rectus Femoris (RF), Vastus Lateralis (VL), Biceps Femoris (BF), Tibialis Anterior (TA), Peroneus Longus (PL) and Gastrocnemius Lateral head (GL) in static (0%, ± 22%) and dynamic (core board) conditions. P-values are represented by asterisks. In each box, p-values represent statistically significant differences among postural conditions within the same group. P-values reported in the x-axis represent statistically significant differences between the two groups under the same postural conditions. (c) MVC results. Boxplots display the maximum voluntary contraction values for the elderly (in green) and for the younger adults (in pink).
