This case report demonstrates the feasibility of a single-lead peripheral nerve
stimulation system for the treatment of pain secondary to chronic subacromial
impingement syndrome.
The participant was a 57-year-old man who experienced
persistent pain from subacromial impingement syndrome for 20 months despite
having undergone conservative therapy of steroid injection and physical therapy.
After study enrollment, a single intramuscular lead was placed percutaneously
into the deltoid muscle of the affected shoulder. 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 0-10 numerical rating scale. At baseline, BPI 3 was an 8. At
the end of treatment and at 4 and 12 weeks after treatment, BPI 3 scores were 2,
0, and 0, respectively. Substantial improvements in shoulder impairment, quality
of life, and shoulder disability measures were also observed. 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.
