Fig. 2From: Effects of whole body vibration exercise on lumbar-abdominal muscles activation for patients with chronic low back painPost-hoc analysis of the muscle activity of MF during different WBV conditions. The degree of muscle activation is described as a percentage (%) of no-WBV conditions during the same exercises. Standardised error of the mean is expressed by error bars. * Significant muscle activation comparison with 5 Hz frequency (paired t-test; p ≤ 0.05).
