Effect of the Diaphragm Stretching Technique on Nonspecific Low Back Pain

In the control group, manual contact will be carried out without any therapeutic intention. This contact will be maintained for the same period of time as the experimental group.

The participant will be in supine position and the researcher will be at the headrest of the examination table, placing his hands on the lower costal margin. Superior direction traction is performed during inspiration, remaining during expiration. The procedure is repeated for a maximum period of 4 minutes.
