Chronic shoulder pain due to impingement syndrome and supraspinatus tendinosis is a debilitating condition. Suprascapular nerve innervates most part of shoulder joint. Supraspinatus nerve block can be used as a part of pain therapy. However, its efficacy is short-lasting. To prolong analgesia, short bursts of electrical stimulation to suprascapular nerve may be applied. To the date there is no consensus about duration of these type of stimulation. Investigators' aim is to investigate efficacy of two different duration of stimulation (pulsed radiofrequency) on chronic shoulder pain.
Patients aged 18-80 years
Shoulder pain caused by impingement syndrome
Shoulder pain due to supraspinatus tendinosis
Diagnosis of impingement syndrome and supraspinatus tendinosis confirmed through physical examination and radiological imaging (MRI)
Patients unwilling to participate in the study
Presence of chronic pain due to other conditions
Presence of cervical radiculopathy
History of opioid use
Parallel
suprascapular nerve block and 4 mins Pulsed radiofreuency application to suprascapular nerve
Procedure/Surgerysuprascapular nerve pulsed rf
suprascapular nerve block and 9 mins Pulsed radiofreuency application to suprascapular nerve
Procedure/Surgerysuprascapular nerve block and 4 mins Pulsed radiofreuency application to suprascapular nerve
Postprocedure 3th month pain severity
Severity of pain will be assessed with Numeric Rating Scale (NRS-11) at baseline, 1 weeks, 1 months and 3 months after interventions. NRS-11 is a 11 point likert type scale. Higher scores represent more severe pain.
Postprocedure pain severity at first week
Severity of pain will be assessed with Numeric Rating Scale (NRS-11) at 1 week after interventions. NRS-11 is a 11 point likert type scale. Higher scores represent more severe pain.
Postprocedure first month pain severity
Severity of pain will be assessed with Numeric Rating Scale (NRS-11) at 1 month after interventions. NRS-11 is a 11 point likert type scale. Higher scores represent more severe pain.
Postprocedure SPADI scores at first week
Functionality will be assessed with Shoulder Pain and Disability Index (SPADI) at 1 week. SPADI measures pain and disability related shoulder function. SPADI has 0 minimum and 100 maximum value. Lower scores represent better outcomes.
Postprocedure first month SPADI scores
Functionality will be assessed with Shoulder Pain and Disability Index (SPADI) at 1 month. SPADI measures pain and disability related shoulder function. SPADI has 0 minimum and 100 maximum value. Lower scores represent better outcomes.
