Comparison of the Efficacy of Ultrasound Guided vs Non-guided Suprascapular Nerve Block Treatment in Stroke Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

Ultrasound-guided Suprascapular Nerve Block: For suprascapular nerve block, a solution consisting of 5 ml 2% lidocaine, 1 ml Betamethasone dipropionate + Betamethasone sodium phosphate (6.43 mg/ml + 2.63 mg/ml), 4 ml saline will be used. Injections will be applied to patients in a sitting position and arm by the side. A linear probe with a frequency of 7-8 MHz on the SonoScape A8 ultrasound device will be used for suprascapular block under ultrasound guidance. the ultrasound probe was placed in the coronal plane over the suprascapular fossa. Suprascapular fossa was scanned from medial to lateral side to identify suprascapular nerve. After identification, solution of suprascapular nerve block will be injected into the area around the nerve under the scanning with in-plane technique with a 22 gauge 90 mm spinal needle.

Anatomical Landmark-guided Suprascapular Nerve Block: For suprascapular nerve block, a solution consisting of 5 ml 2% lidocaine, 1 ml Betamethasone dipropionate + Betamethasone sodium phosphate (6.43 mg/ml + 2.63 mg/ml), 4 ml saline will be used. Injections will be applied to patients in a sitting position and arm by the side. The suprascapular notch projection will be determined using the anatomical landmark technique defined by Dangoisse et al., and then suprascapular nerve block will be applied with a 22 gauge 90 mm spinal needle to the patients

Study summary

The aim of this study is to compare the effectiveness of ultrasound-guided and non-guided suprascapular nerve block in the treatment of patients with hemiplegic shoulder pain, which is one of the most common post-stroke complications.

Eligibility

Primary outcome measure(s)

• Shoulder Range of Motion — Before suprascapular nerve block
  The range of motion of the hemiplegic shoulder joint will be measured passively with a goniometer in the flexion, abduction, internal rotation and external rotation directions.
• Shoulder Range of Motion — 1 week after suprascapular nerve block
  The range of motion of the hemiplegic shoulder joint will be measured passively with a goniometer in the flexion, abduction, internal rotation and external rotation directions.
• Shoulder Range of Motion — 4 week after suprascapular nerve block
  The range of motion of the hemiplegic shoulder joint will be measured passively with a goniometer in the flexion, abduction, internal rotation and external rotation directions.
• Shoulder Range of Motion — 12 week after suprascapular nerve block
  The range of motion of the hemiplegic shoulder joint will be measured passively with a goniometer in the flexion, abduction, internal rotation and external rotation directions.
• Visual Analogue Scale — Before suprascapular nerve block
  Pain was evaluated using a 10 cm long Visual Analogue Scale (VAS) during rest and activity (0 = no pain, 10 = very severe pain).
• Visual Analogue Scale — 1 week after suprascapular nerve block
  Pain was evaluated using a 10 cm long Visual Analogue Scale (VAS) during rest and activity (0 = no pain, 10 = very severe pain).
• Visual Analogue Scale — 4 week after suprascapular nerve block
  Pain was evaluated using a 10 cm long Visual Analogue Scale (VAS) during rest and activity (0 = no pain, 10 = very severe pain).
• Visual Analogue Scale — 12 week after suprascapular nerve block
  Pain was evaluated using a 10 cm long Visual Analogue Scale (VAS) during rest and activity (0 = no pain, 10 = very severe pain).
