This study sought to establish the efficacy of single-lead, 3-wk
peripheral nerve stimulation (PNS) therapy for pain reduction in stroke survivors
with chronic hemiplegic shoulder pain. DESIGN:
This study is a single-site,
pilot, randomized controlled trial of adults with chronic shoulder pain after
stroke. Participants were randomized to receive a 3-wk treatment of single-lead
PNS or usual care. The primary outcome was the worst pain in the last week (Brief
Pain Inventory, Short Form, question 3) measured at baseline and weeks 1, 4, 12,
and 16. The secondary outcomes included pain interference (Brief Pain Inventory,
Short Form, question 9), pain measured by the ShoulderQ Visual Graphic Rating
Scales, and health-related quality-of-life (Short-Form 36 version 2). RESULTS:
Twenty-five participants were recruited, 13 to PNS and 12 to usual care. There
was a significantly greater reduction in pain for the PNS group compared with the
controls, with significant differences at 6 and 12 wks after treatment. Both PNS
and usual care were associated with significant improvements in pain interference
and physical health-related quality-of-life. CONCLUSIONS: Short-term PNS is a
safe and efficacious treatment of shoulder pain. Pain reduction is greater
compared with usual care and is maintained for at least 12 wks after treatment.
