SPR Therapeutics implants shoulder-pain device in first stroke patient

SPR Therapeutics' Smart patch

Neurostimulation startup SPR Therapeutics has reached an important milestone, implanting its post-stroke shoulder-pain device in a patient for the first time.

A 76-year-old man suffering from shoulder pain is now pain-free after being implanted with the device at Carolinas Medical Center in Charlotte, North Carolina. The patient also reported a better quality of life, with improvements in sleep, mood and relationships with other, according to a statement from Cleveland-area SPR.

SPR’s pain-relief system is aimed at reducing shoulder pain in patients who’ve suffered strokes. The technology works via an external generator that electrically stimulates a peripheral nerve to exercise a muscle and treat a patient’s pain.


SPR has developed a two-stage process for pain relief: First, a patient is treated with the company’s short-term device, the Smartpatch. Next, the patient is implanted with the company’s MicroPulse long-term MicroPulse device.

SPR is also studying its system in patients suffering shoulder pain not related to stroke.

The company recently filed a regulatory document indicating it had raised $1 million of an anticipated $2 million series A round of investment.

CEO Maria Bennett wasn’t available for comment.
