Previous studies demonstrated the efficacy of 6 weeks of a 4-lead percutaneous,
peripheral nerve stimulation system in reducing hemiplegic shoulder pain. This
case report describes the first stroke survivor treated for 3 weeks with a less
complex, single-lead approach. The participant was a 59-year-old male who
developed hemiplegic shoulder pain shortly after his stroke 7.5 years prior to
study enrollment and was treated with multiple modalities without sustained pain
relief. After study enrollment, a single intramuscular lead was placed
percutaneously into the deltoid muscle. He was treated 6 hours per day for 3
weeks and the lead was removed. The primary outcome measure was the Brief Pain
Inventory (Short-Form) Question 3 (BPI-3), which queries the worst pain in the
last week on a 0 to 10 numeric rating scale. At baseline, BPI 3 was an 8. At the
end of treatment and at 1 and 4 weeks after treatment was completed, BPI 3 scores
were 3, 2, and 2, respectively. Substantial improvements in quality of life
measures were also observed. The participant remained infection-free and the lead
was removed fully intact. After completing the study protocol, the participant
was followed clinically for 13 months posttreatment with complete resolution of
hemiplegic shoulder pain.
This case report demonstrates the feasibility of a
single-lead peripheral nerve stimulation for the treatment of chronic hemiplegic
shoulder pain. Additional studies are needed to further demonstrate safety and
efficacy, determine optimal dose, define optimal prescriptive parameters, expand
clinical indications, and demonstrate long-term effect.
