This randomized single blind three arm clinical trial aims to compare the effectiveness of Suprascapular Nerve Block, Hydrodilatation, and their combination in patients with Grade III periarthritis shoulder. A total of 165 adults below 60 years with at least nine months of shoulder pain and stiffness not responding to conservative treatment will be enrolled and randomized equally into three groups. All procedures will be performed under ultrasound guidance using standard drug protocols.
The primary objective is to assess pain reduction using the Visual Analogue Scale. Secondary objectives include improvement in range of motion measured by goniometry, functional outcome assessed by the Shoulder Pain and Disability Index, and sleep quality assessed using the Pittsburgh Sleep Quality Index.
Follow up assessments will be conducted at two weeks, six weeks, and twelve weeks. Patients with recent trauma or surgery, uncontrolled endocrine disorders, infection, neurological illness affecting the shoulder, coagulopathy, or drug allergies will be excluded.
Data will be analyzed using appropriate parametric or non parametric tests. The study is expected to identify whether the combination of suprascapular nerve block and hydrodilatation provides superior clinical improvement compared to either treatment alone in frozen stage periarthritis shoulder.
