Brief Summary
Frozen shoulder remains a challenging disease to treat as pain and loss of range of motion can persist for many months or even years. This loss of function can have a severe impact on the patient's activities, participation and overall quality of life. The use of ultrasound-guided (USG) suprascapular nerve blocks (SSNB) and/or intra-articular corticoid injections (IACI) has been supported by many studies. However, double blinded randomized clinical trials using a combination of SSNB and IACI are rare. The primary objective of this study is to compare the effectiveness of a glenohumeral IACI combined with a SSNB, compared to a glenohumeral IACI combined with a sham SSNB. Outcome measures of interest are shoulder-related disability reported by the patients, shoulder pain and shoulder stiffness. These outcome parameters will be compared between both treatment arms with an intention-to-treat analysis. As key secondary objectives, the investigators aim to identify which physical examination tests, or combinations of those, are correlated with MRI diagnostic criteria and favor a more positive evolution. Finally, through predictive analysis the investigators will try to establish which patients benefit the most from the combined SSNB + IACI.

Outcome Measures
Primary Outcomes (1)
Shoulder Pain and Disability Index (SPADI)
The Shoulder Pain and Disability Index (SPADI) is a self-administered index consisting of 13 items, divided into two subscales: 5 items for pain and 8 items for disability. It can be completed by patients in less than 5 min and has shown good reliability and construct validity in the assessment of shoulder impairments and in particular frozen shoulder. The score for each subscale is obtained by adding up all the individual subscale scores and dividing the result by the maximum subscale score. The normalized score is converted to a scale from 0 to 100, with 100 indicating no problems and 0 indicating serious problems.

Study Arms (2)
SSNB + IACI
ACTIVE COMPARATORPatients randomized to this arm will receive a SSNB (20-mg methylprednisolone acetate and 5-mL Ropivacaine 2mg/ml) than a IACI (40-mg methylprednisolone acetate and 1-mL Ropivacaine 2mg/ml). Rehabilitation/physiotherapy is considered standard of care.
Short-acting SSNB + IACI
PLACEBO COMPARATORPatients randomized to this arm will receive a SSNB (5-mL Linisol 10mg/ml) than a IACI (40-mg methylprednisolone acetate and 1-mL Ropivacaine 2mg/ml) Rehabilitation/physiotherapy is considered standard of care.
Interventions
Usual care: All patients complete rehabilitation under supervision of their own physiotherapist. The investigators will provide some guidelines and criteria but is the physiotherapist's choice how to implement these guidelines in clinical practice. Patient education on home-exercises Monitoring of peak pain, at rest/night and after rehabilitation sessions using a Numeric-Pain-Rating-Scale (0-10) (NPRS) to evaluate tissue irritability and guide physiotherapy and rehabilitation. Use of passive physiotherapy (cold, heat or electric therapies) to treat pain. Active and passive mobilization of the shoulder under the pain threshold, Maitland mobilization, stretch exercises such as: table slides, wall climbers. Use of affected upper limb in pain free Range-of-Motion (ROM) is tolerated and stimulated. Progressively increase time and frequency of Total-End-Range-Time (TERT) positions to increase ROM

- Masking Details
- All patients will receive 2 concomitant USG injections: first a SSNB than an IACA Control group : short-acting SSNB is performed with a short-acting local anesthetic (Linisol 2%). Intervention group : SSNB is performed with a long-acting anesthestic (Ropivacaine 2%) + 20-mg methylprednisolone acetate. Same injected volume (5ml) in sham and intervention group. The advantage of using a short-acting anesthetic as a sham injection instead of a saline, is that at the time of injection the patient may perceive the anticipated short effect of the anesthetic similar to the intervention SSNB. The care provider will be unaware of the type of SSNB of the allocation group. The outcomes assessor will be unaware of the type of SSNB of the allocation group. The investigator who administers the injections, will be unaware of the allocation. The investigational products will be prepared by the pharmacist according to a pre-defined co-variate constrained randomization key.
