Plain English Summary
Background and study aims
Adhesive capsulitis (also known as frozen shoulder) is a condition that leads to pain and stiffness of the shoulder. Clinical studies have reported the safety and effectiveness of injecting hyaluronate into the shoulder joint of patients with adhesive capsulitis. The aim of this study is to assess the effectiveness of a hyaluronate and tramadol injection for adhesive capsulitis of the shoulder.
Who can participate?
Patients with adhesive capsulitis of the shoulder
What does the study involve?
Participants are randomly allocated to the hyaluronate group or the tramadol group. Hyaluronate group members receive five weekly hyaluronate injections. Tramadol group members receive three weekly hyaluronate and tramadol injections, and then two weekly injections of hyaluronate. Range of motion of the shoulder joint and shoulder pain are assessed at the start of the study and 1, 2, 3, 4, and 6 weeks after the first injection.
What are the possible benefits and risks of participating?
Participating helps us to find more effective treatments and does not exceed the minimum risk that may arise in day-to-day treatment.
Where is the study run from?
Soonchunhyang University Hospital (South Korea)

Scientific title
The effect of intra-articular hyaluronate and tramadol injection on patients with adhesive capsulitis of the shoulder: a single-blind randomised control trial
Acronym
Study hypothesis
More significant changes occur in pain, ROM, and function of shoulder joints when hyaluronate and tramadol are injected together into the joints as treatment for adhesive capsulitis of the shoulder than injected hyaluronate alone.

Condition
Adhesive capsulitis of shoulder
Intervention
The control group (hyaluronate group) was injected only with hyaluronate (Hyal Shin Poong, PhD, Korea, 2.5-mL injection, 1% hyaluronan, molecular weight 940–1,020 kDa) five times in 1-week intervals.
The experimental group (tramadol group) received hyaluronate and tramadol (Tridol Shin Poong, PhD, Korea, 100 mg, 1-mL injection) 50-mg injections three times, and then they received two injections of only hyaluronate afterward. Intra-articular injection was administered by one doctor using the posterior approach
