This study evaluated the effects of repeated, self-administered hamstring muscle stretching on activation of the erector spinae muscles in chronic low back pain patients. The study was performed on 24 patients with no other diagnosis or history of surgical treatment. Volunteers with right-sided back pain were recruited. All subjects performed 3 sets of self-administered hamstring muscle stretching exercises 10 times daily, in each of 3 directions. After the intervention, static and dynamic muscle activity of the erector spinae muscles was measured with the MyoVision 3G Wirefree system. Static muscle activation significantly changed after intervention at C7, T3, and T1 on the right side and at C4, T3, T6, T9, and T10on the left side. In addition, dynamic muscle activation for right side flexion-peak and flexionminchanged significantly after intervention. We conclude that self-administered hamstring stretching can indirectly reduce erector spinae muscle activation.
