abstract
The purpose of this study was to understand alterations of muscle stiffness and muscle activity in the dorsolumbar muscle quantitatively by exercising with a Stretch Pole®. The subjects were fifteen healthy adults (5 men and 10 women) who did not have low back pain. The Basic Seven exercise with the Stretch Pole® was applied as an exercise protocol. We measured the muscle stiffness and muscle activity of the bilateral elector spinae at the height of the tenth thoracic vertebra and third lumbar vertebra to make a comparison before and after exercise with the Stretch Pole® using a tactile sensor and surface electromyography on standing. The results of this study showed that there were no significant differences between muscle stiffness and muscle activity on each side of elector spinae at either height, when we made a comparison before and after exercise with the Stretch Pole®. However, there were significant differences of absolute right and left muscle stiffness in the elector spinae at the height of the tenth thoracic vertebra (p<0.025). It is suggested that right and left differences of muscle stiffness in the elector spinae at the height of the tenth thoracic vertebra were influenced by the Basic Seven which were the basis of exercise with the Stretch Pole®.
