Efectos del estiramiento isquiotibial sobre el patrón de activación muscular del erector spinae durante la flexoextensión de tronco

Repeated hamstring stretching did not produce any variations on the erector spinae myoelectric silence duration period, although it significantly changed erector spinae EMG activity during trunk extension. This could imply an alteration on the muscular coactivation that is necessary for lumbar spine stability.
