DJO UK Ltd (ENOVIS) is conducting this study to assess the effectiveness of LightForce® Therapy Lasers on pain reduction in shoulder soft tissue inflammation. In detail this study will assess superiority of LightForce® Therapy Lasers combined with standard of care, represented by physiotherapy/exercise program compared to sham laser combined with standard of care (physiotherapy/exercise program) on pain reduction in subjects with shoulder soft tissue inflammation due to Impingement (Subacromial impingement syndrome (SAIS)) or Rotator Cuff Tendinopathy (RCT),. In addition, this study allows to collect post market clinical data on the safety and performance of LightForce® Therapy Lasers, when used, following the normal clinical practice, in accordance with its approved and CE marked intended use.

This clinical investigation is a post-market, International, multi center, prospective, randomized, sham controlled, single blind study to assess the effectiveness of LightForce® Therapy Lasers and to collect PMCF data on the safety and performance of LightForce® Therapy Lasers, when used in accordance with its approved labeling, to comply with Medical Device Regulation (EU) 2017/745 (MDR) Article 61 and Part B of Annex XI.

Inclusion Criteria:

1. Patient male or female with age ≥18 years old
2. Patient with diagnosis of shoulder soft tissue inflammation due to SAIS/RCT (as confirmed by physical examination and/or imaging) to be treated by LightForce® Therapy Lasers according to its indications.
3. Patient suffering from shoulder soft tissue inflammation due to SAIS/RCT pain for more than 3 months prior to enrollment
4. Pain (either persistent or during activities) score reported by the subject at baseline ≥ 40 mm measured on VAS
5. Patient able to provide written informed consent

Exclusion Criteria:

1. Patient with musculoskeletal pathological conditions not to be treated with/contraindication to the use of LightForce® Therapy Lasers according to its intended use and indications

6. Patients who underwent intra-articular injection (Ialuronic acid, platelet rich plasma or corticosteroids) in the shoulder in the last 3 months
7. Patients who have a disease that would limit their participation in exercises (i.e. severe chronic obstructive pulmonary disease, severe heart failure, cerebrovascular event history)
8. Patients with a prior history of surgical intervention and implantation of a metal implant into the affected shoulder
9. Patients with a diagnosis of active cancer
10. Patients with tattoos covering more than 30% of the area to be treated with LightForce® Therapy Lasers
11. Patients who are mentally or physically incapacitated
12. Patient participating in other clinical study or has completed a clinical study less than 30 days prior to enrollment
13. Patient affected by shoulder soft tissue acute inflammation due to recent sport injury or trauma
14. Patients with other musculoskeletal problems of the shoulder joint such as calcifying tendinitis, full thickness rotator-cuff tear, adhesive capsulitis, fibromyalgia, recent surgery or fracture of the shoulder joint, and/or undergoing to specific physiotherapy for these ("recent" is defined as within 30 days prior to enrollment).
15. Patients with other clinically significant co-morbidities that make the patient unsuitable for study participation, at the discretion of the investigator
