Dry Needling and Exercises in Shoulder Pain

Study Overview
=================
Brief Summary
-----------------
Shoulder pain is highly prevalent in the society. The role of muscle tissues in this pathology has received increasing interest. Some studies have proposed the role of myofascial trigger points in this population. The purpose of the current clinical trial is to compare the effects of physiotherapy treatment consisting of an eccentric exercise protocol versus the same physical therapy program plus the addition of trigger point dry needling (TrP-DN) on pain and function in patients suffering from unspecific shoulder pain.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental group<br>Patients will be asked to perform an eccentric loading exercise program for the shoulder musculature, particularly the supraspinatus and infraspinatus muscles, to be performed on an individual basis twice every day. The therapeutic protocol will be applied for 5 weeks. In addition, within the second and fourth sessions, they will receive TrP-DN over active TrPs in the shoulder muscles | Other: exercise program<br>* Patients will be asked to perform an eccentric loading exercise program for the shoulder musculature, particularly the supraspinatus and infraspinatus muscles, to be performed on an individual basis twice every day. The therapeutic protocol will be applied for 5 weeks.<br>Other: TrP-DN<br>* In addition, within the second and fourth sessions, they will receive TrP-DN over active TrPs in the shoulder muscles<br>|
| Active Comparator: Control group<br>Patients will be asked to perform an eccentric loading exercise program for the shoulder musculature, particularly the supraspinatus and infraspinatus muscles, to be performed on an individual basis twice every day. The therapeutic protocol will be applied for 5 weeks. | Other: exercise program<br>* Patients will be asked to perform an eccentric loading exercise program for the shoulder musculature, particularly the supraspinatus and infraspinatus muscles, to be performed on an individual basis twice every day. The therapeutic protocol will be applied for 5 weeks.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in disability between baseline and follow-up periods | The Disabilities of the Arm, Shoulder and Hand (DASH) will be used to determine the disability induced by shoulder pain | Baseline, one week after the last intervention and 3, 6 and 12 months after the intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in shoulder pain between baseline and follow-up periods | A 10-point Numerical Pain Rating Scale (NPRS; 0: no pain, 10: maximum pain) will be used to assess the patients' current level of shoulder pain and the worst level of pain experienced in the preceding week in the shoulder area. | Baseline, one week after the last intervention and 3, 6 and 12 months after the intervention |
