Universidad Europea de Madrid Objectives We expose the case of a 38 -year-old male patient, undergoing three arthroscopic surgeries on his right shoulder, who presented pain and functional limitation refractory to conservative and interventional treatments. Prior psychological evaluation, peripheral nerve stimulation system was implemented. Methods The patient undergoes peripheral stimulation system implant (Bioness stimrouter®) under local anesthesia and sedation, with ultrasound control (figure 1, 2, 3, 4). Programming with symmetric wave, 200 µs, 70 Hertz, stimulated 90 minutes per day. Figure 1 Figure 2 We analyzed the pain relief with a simple numeric rating scale (NRS) with values from 0 to 10 at rest and in activity, being 0 no pain and 10 the worse pain ever; LIKERT scale of improvement percentage (1 - 75% worse; 2 - 50% worse; 3 - 25% worse; 4 - same as before; 5 - 25% better; 6 - 50% better; 7 - 75% better); quality of life with DASH questionnaire (Disabilities of the Arm, Shoulder and Hand), analyzing 30 items with values from 1 to 5, the results were measured in percentage, indicating the highest percentage values worst measured in quality of life. The values were recorded at baseline(T 0) and 2(T 1), 5(T 2), 7(T 3), 10(T 4) and 12 months(T 5) Figure 3 Figure 4 1

Universidad Europea de Madrid Results Basal and activity NRS (0 -10) (graphic 1). LIKERT (1 -7) with an improvement of more than 50% in all periods studied. DASH (0 -100) (graphic 2). Results The patient completely discontinued the medication he took before implanting. There were no technical complications. Conclusions Peripheral nerve stimulation could be a therapeutic alternative in patients with postsurgical omalgia refractory to conservative and interventional treatments. 2
