Dry Needling Versus Conservative Treatment in the Rectus Femoris Muscle Approach.

In recent years, dry needling techniques have become widespread in the field of musculoskeletal pain treatment. Specifically, the management of myofascial trigger points has been the focus of these techniques. One of the objectives has been to improve the flexibility of those muscles that, due to the presence of myofascial trigger points, had a decrease in this parameter. This study aims to determine whether the application of a dry needling technique is more effective than analytical stretching of the muscle.
