Effects of Dry Needling on the Behavior of the Shoulder Muscles

Effect of Dry Needling Technique on Shoulder Muscle Functionality in Subjects With and Without Shoulder Pain.

The main objective of this study will be to evaluate the effects of the application of the dry needling technique on the activity of the rotator cuff muscles in the shoulder.

The evaluation of the effects of the application of the dry needling technique will be carried out in subjects with and without shoulder pain.To do this, muscle strength, possible thickness changes in the muscle and electromyographic activity will be measured before and immediately after the application of a dry needling technique.

Likewise, other variables will be measured such as the pressure pain threshold (PPT), pain with a Numeric Verbal Scale, kinesiophobia and catastrophism, the shoulder pain and disability index (SPADI) and the influence of expectations about dry needling.
