Effects of Dry Needling on the Behavior of the Shoulder Muscles
- Conditions
- Shoulder Pain

- Other: Sham dry needlingOther: Real dry needling
- Registration Number
- NCT06398574
- Lead Sponsor
- University of Alcala
- Brief Summary
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.

Group Intervention Description Sham dry needling Sham dry needling With the subject lying supine, a sham dry needling technique will be applied to the infraspinatus muscle, simulating the real procedure. Real dry needling Real dry needling With the subject lying supine, a dry needling technique will be applied to the infraspinatus muscle.
- Primary Outcome Measures
Name Time Method Muscle strength Change from Baseline at 15 minutes. The isometric strength will be assessed using a handheld dynamometer (Hand held dynamometer, MicroFET3; Hoggan Health Industries Inc.). The strength measures will included external rotation at 90° abduction in the prone position. The dynamometer will be placed just proximal to the just proximal to the styloid process of the wrist joint. Subjects will be asked to produce a 5-second maximal contraction. Muscular strength will be measured in kilograms
- Secondary Outcome Measures
Name Time Method Muscle function Change from Baseline at 15 minutes. Muscle function will be measured by an ultrasound scanner with a linear transducer with a frequency range of 6-16MHz (X6-16L, 5cm footprint) will be used. The unit of measurement used will be millimeters. Muscle thickness at rest and contraction will be measured. On the other hand, the percentage of change in thickness will be measured using the equation (Contraction thickness - Rest thickness) \* 100 / Rest thickness.
Shoulder Pain Change from Baseline at 15 minutes. Pain intensity will be measured using the Visual Analog Scale (VAS) for pain. The VAS is a 100-mm line, oriented horizontally, with one end representing "no pain" and ten the other end representing "worst pain." Subjects will be asked to rate their current pain with a mark on the scale.
Pressure Pain Threshold (PPT) Change from Baseline at 15 minutes. An algometer Wagner FPI 10-WA will be used to determine the PPT in infraespinatus muscle.
Disability Change from Baseline at 15 minutes. Disability will be measured by Shoulder Pain and Disability Index (SPADI).The Spanish version of SPADI has high test-retest reliability (ICC 0.89-0.93).The clinically important minimum difference varies between 8 and 13.2. The minimum value is 0 and de maximum value is 100
