This study evaluates the treatment of hamstrings in the management of patients with mechanical low back pain of non-specific origin. Half of the participants will received the application of a dry needle technique in the most hyperalgesic areas of the muscle, while the other half will received the same technique in areas not hyperalgesic.


Shortening of the hamstrings could be related to low back pain.Therefore, the treatment of these muscles may improve pain.

The dry needling technique seems to improve the extensibility of the muscles. This technique seems to be more effective when is applied in the most hyperalgesic areas related to the participant's pain.

In order to demonstrate this hypothesis, the investigators will check if the dry needling technique produces the same effects when is applied in other areas of those same muscles
