The purpose of this study is to evaluate the effect of adding pulsed radiofrequency (PRF) modality to suprascapular nerve injection with ultrasound glenohumeral steroid in chronic shoulder pain patients focusing on both changes in pain and function scores
Shoulder pain is the second most prevalent musculoskeletal condition in adults which is frequently treated poorly and results in chronic pain . The use of steroid injection has been demonstrated to be superior to conventional therapies, particularly non-steroidal anti-inflammatory drugs. Its impact is transient (4-6 weeks) and occasionally may not be clinically sufficient . An alternate analgesic injection for the pain management of numerous shoulder diseases is the suprascapular nerve block (SSN) . Although pulse radiofrequency analgesia typically lasts for a much longer period than nerve blocking, it has become increasingly popular to apply pulse radiofrequency to peripheral nerves.

Suprascapular nerve block group: Patients will receive ultrasound guided intra articular Gleno-humeral steroid injection of Diprofos® (betamethasone 14 mg/ 2ml) and ultrasound guided suprascapular nerve block US SSN with 10mL of 0.25% preservative-free bupivacaine Pulsed radiofrequency group: Patients will receive ultrasound guided intra articular Gleno-humeral steroid injection of Diprofos® (betamethasone 14 mg/ 2ml) and ultrasound guided suprascapular nerve block US SSN with 10mL of 0.25% preservative-free bupivacaine with application of pulse PRF at 42 Celsius of suprascapular nerve for 480 seconds.

RECRUITINGchange of Shoulder Pain and Disability Index (SPADI) questionnaire in both groups after the intervention
The Shoulder Pain and Disability Index (SPADI) a self-administered questionnaire that consists of two dimensions, one for pain and the other for functional activities, overall total scores range from 0 to 130 with a percentage score of 0 indicating less shoulder disability and 100 indicating more shoulder dysfunction
Time frame: 15th day, 1st month, 3rd month and 6th month
Numerical pain rating scale (NRS).physiological parameter
patients are asked to circle the number between 0 and 10, 0 and 20 or 0 and 100 that fits best to their pain intensity. Zero usually represents 'no pain at all' whereas the upper limit represents 'the worst pain ever possible'.
Time frame: 15th day, 1st month, 3rd month and 6th month
Duration of pain relief physiological parameter
when the effect of the intervention will be lost after the intervention
Time frame: 15th day, 1st month, 3rd month and 6th month
Active range of motion (AROM).physiological parameter
will be measured using a geniometer.
Time frame: 15th day, 1st month, 3rd month and 6th month
