Comparative study between pulsed radiofrequency in suprascapular nerve or bupivacaine block for chronic shoulder pain
Prospective, randomized, comparative study of 40 participants with chronic shoulder pain allocated into two groups. Patients in group 1 underwent pulsed RF (180sec, with a fixed temperature at 42C, twice) on the suprascapular nerve, and the other group, 2, underwent nerve block with bupivacaine (5ml). After the procedure, patients were evaluated for 3 months regarding pain intensity, shoulder range of motion and dose of rescue opioids.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Pulsed Radiofrequency | Active Comparator | The investigators performed pulsed radiofrequency in the suprascapular nerve |
|
| Bupivacaine | Active Comparator | The investigators performed a blocade with bupivacaine in the suprascapular nerve. |

| Suprascapular nerve block with bipuvacaine | Drug | Suprascapular nerve block with Bipuvacaine: a 50mm 22G needle (Stimuplex, BBraun) was introduced up to the suprascapular fossa, guided by ultrasound, and the location was confirmed by motor stimulation with contraction of the supraspinatus and infraspinatus muscles. Next, 5 ml of 0.25% bupivacaine with adrenaline was injected. |
| Measure | Description | Time Frame |
|---|---|---|
| Comparison of pain intensity after application of pulsed RF in the suprascapular nerve versus injection of a local anesthetic. | Comparison of pain intensity after application of pulsed RF to the suprascapular nerve and after injection of a local anesthetic. The numerical pain scale (Visual Analogue Scale - VAS) at rest and during movement was used. This scale (VAS) ranges from 1 to 10, with 1 representing mild pain and 10 representing severe pain. | 12 months |
| Measure | Description | Time Frame |
|---|---|---|
| To assess the range of motion of the shoulder joint | To assess the range of motion of the shoulder joint. A goniometer was used to assess the range of motion. | 12 months |
| Need for additional analgesic. |

Participants were allocated to groups using a random sequence of numbers generated by computer using the Randomizer® program (www.random.org). The number of patients and the groups to which they would belong were randomly drawn. These numbers were placed in envelopes numbered from 1 to 40, which were drawn on the day of the consultation.

| Pulsed radiofrequency | Procedure | After confirming the location, the needle mandrel was removed and the radiofrequency cannula was introduced through the needle, 2ml of 1% lidocaine without epinephrine was injected, followed by application of pulsed radiofrequency for 180sec at 42°C by radiofrequency (radiofrequency generator system BMS-50N, Bramsys). |
