Plain English Summary
Background and study aims
Shoulder pain is a very common problem, which is often a complication of a disorder affecting the muscles in the shoulders. Treatment of long-term (chronic) should pain often involves physical therapy, using involving moving the shoulder joint around (manual therapy) and practicing exercises. Dry needling is a technique often used for pain management. It involves using either solid filiform needles (acupuncture needles) or hollow-core hypodermic needles to stimulate certain trigger points (myofacial trigger points) in the muscles to relieve pain. The aim of this study is to investigate the effectiveness of dry needling combined with manual therapy and therapeutic exercises in relieving pain and improving function in patients with chronic shoulder pain.
Who can participate?
Adults with long-term shoulder pain who have sensitive myofacial trigger points in their shoulder muscles.
What does the study involve?
Participants are randomly allocated to one of two groups who attend six study visits over six weeks. In the first study visit, patients either have dry needling, in which trigger points in their shoulders being treated with a filiform needle which is introduced through the skin into the muscle for 15 seconds, or sham needling, in which a sham (placebo) needle is used to prick the skin but not reach the muscle in the trigger points. For the remaining sessions, participants in both groups complete 75 minutes of manual therapy with a physiotherapist as well as practicing shoulder movement exercises twice a week for six weeks. Participants in both groups have their pain levels and shoulder function tested at the start of the study and then after one week, three months and six months.
What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with participating in this study.

Shoulder pain of unspecified origin
Participants are randomised to one of two treatment groups using Epidat 3.1 software.
Intervention group: Participants attend six study visits over a period of six weeks. In the first session, participants undergo Deep Dry Needling of the hyperalgesic points of infraspinatus muscle, upper trapezius, middle deltoid and subscapularis. This involves each muscle being treated with a filiform needle that will be introduced through the skin in order to eliminate pain. The technique is applied for 15 seconds on each muscle. For the remaining sessions, participants undergo 75 minutes of manual therapy, which involves practicing joint mobilization techniques in the glenohumeral joint, mobilization of the scapula, compression techniques and stretching of muscles.
Control group: Participants attend six study visits over a period of six weeks. In the first session, participants undergo Sham Dry Needling of the hyperalgesic points of infraspinatus muscle, upper trapezius, middle deltoid and subscapularis. his involves each muscle being treated with a placebo needle, i.e. the patient will feel pricking of the skin but the needle does not reach the muscle. For the remaining sessions, participants undergo 75 minutes of manual therapy, which involves practicing joint mobilization techniques in the glenohumeral joint, mobilization of the scapula, compression techniques and stretching of muscles.
Participants in both groups are asked to perform domiciliary Therapeutic Exercises twice a week, on non-consecutive days. These exercises involve active movement exercises without pain and stretching of muscles
Primary outcome measure
1. Functionality and quality of life is measured using the disabilities of the arm, shoulder and hand (DASH) scale at baseline, 1 week, 3 and 6 months
2. Pain is measured using a visual analogue scale (VAS) at baseline, 1 week, 3 and 6 months
Secondary outcome measures
1. Range of Motion (ROM) is measured using a goniometer at baseline, 1 week, 3 and 6 months
2. Medication intake is measured using interview at baseline, 1 week, 3 and 6 months
3. Pressure Pain Threshold (PPT) is measures using a algometer baseline, 1 week, 3 and 6 months
