This case report describes the first participant treated with a fully
implantable, single-lead peripheral nerve stimulation system for refractory
hemiplegic shoulder pain. During the 6-wk trial stage, a temporary lead was
placed percutaneously near the terminal branches of the axillary nerve to the
deltoid. The primary outcome measure was the Brief Pain Inventory-Short Form
Question 3, a 0-10 pain numeric rating scale. The participant experienced 75%
pain reduction and proceeded to the implantation stage, where he received a
single-lead, implantable pulse generator. After 3 wks, the participant became
pain-free. However, 7 wks after implantation, the system was turned off because
of an unrelated acute medical illness. Hemiplegic shoulder pain reemerged with a
Brief Pain Inventory-Short Form Question 3 score of 9. After 11 wks of recovery,
peripheral nerve stimulation was reinitiated and the participant became pain-free
through the 9-mo follow-up. At 12 mos, Brief Pain Inventory-Short Form Question 3
score was 1. This case report demonstrates the feasibility of a single-lead,
fully implantable peripheral nerve stimulation system for refractory hemiplegic
shoulder pain.
