简要总结
This is a parallel-group randomised clinical trial:
Primary purpose: To analyse the clinical changes produced by two different physiotherapy treatments (Intratissue Percutaneous Electrolysis and Dry Needling) for myofascial trigger points in the infraspinatus muscle in subjects with non-specific shoulder pain.
Hypothesis: A physiotherapy treatment including Intratissue Percutaneous Electrolysis therapy present greater benefits in terms of pain reduction and increased mobility and functionality rather than Dry Needling treatment in subjects with non-specific shoulder pain.
The intervention consisted of 3 treatment sessions, different according to the group, once a week. Seven evaluation points were performed, two pre-intervention evaluations one week apart and after the second one the first treatment session was performed. The third and fourth assessments were prior to the second and third treatment sessions, one week apart. The fifth, sixth and seventh assessments were conducted one week, one month and two months after the last treatment session in each group.

研究组 & 干预措施
Experimental Group (Intratissue Percutaneous Electrolysis Group)
The treatment to be performed in the Intratissue percutaneus electrolysis Group will consist of:
- Palpation and localization of the myofascial trigger points in the infraspinatus muscle of the affected shoulder.
- Application of the ultrasound-guided intratissue percutaneus electroysis technique (1 or 2 approaches) on the myofascial trigger points with the greatest clinical manifestations for the subject. The needle will remain at intramuscular level without movement and a galvanic current discharge will be applied in the area, through the needle, whose intensity will oscillate between 0.5 and 3 milliAmperes (mA).
- Performance of an eccentric work protocol of the infraspinatus muscle to reduce post-puncture pain.
干预措施: Intratissue Percutaneous Electrolysis (Procedure)
Active Control Group (Dry Needling Group)
The treatment to be performed in the Dry Needling Group will consist of:
- palpation and localization of myofascial trigger points in the infraspinatus muscle of the affected shoulder.
- Application of the ultrasound-guided dry needling technique (1 or 2 approaches) on the myofascial trigger points with major clinical manifestations for the subject. The physiotherapist will move the needle into the muscle using Hong's rapid entry and exit technique.
- Performance of an eccentric work protocol of the infraspinatus muscle to reduce post-puncture pain.
干预措施: Dry Needling (Procedure)
