Minimally Invasive Technique to Increase the Range of Motion of the Shoulder Joint in Frozen Shoulder: Single Arm Prospective Study

STUDY OBJECTIVES The primary objective is to evaluate the effect of combination of regional anesthesia and physical therapy measured as an improvement in pain related disability scores of the impaired shoulder using the Shoulder Disability Questionnaire (SDQ), Shoulder Pain and Disability Index (SPADI), and improvement in pain score measured by Brief Pain Inventory (BPI).

The secondary objectives are to evaluate the effect of treatment on the following:

• Anxiety, measured by General Anxiety Disorder Questionnaire (GAD-7)
• Depression, measured by Beck's Depression Inventory (BDI)
• Satisfaction, measured by Global Improvement and Satisfaction Score (GISS) STUDY DESIGN This is as a single-center, prospective cohort study. The study does not imply any new intervention; all decisions regarding the treatment will be made at the sole discretion of the treating physician as part of clinical care. The study will be conducted over a period of 14 months, including approximately 1-2 months of enrolment, 4-6 weeks of treatment and follow-up at 3, 6, 12 months after the initiation of treatment for frozen shoulder. Treatment 1 can be scheduled along with baseline consult and screening (Day 0), three to five more treatment visits (Treatment 2 to Treatment 6) will be scheduled weekly (4-6 treatments in total), and follow up visits on 3, 6, and 12 months (with ±1week window). If patient has achieved any early full ROM, treatment will be stopped according to the physicians' decision. The study will be conducted at the Allevio Pain Clinic, Toronto, Canada. Research Ethics approvals will be sought.

STUDY POPULATION Patients with unilateral or bilateral frozen shoulder in any stage will be screened for study eligibility.
