I’ve actually been using it with a patient with Dupuytren’s recently. They had a local infection from a thorn, and it started after that. I couldn’t find any research on it, but I’ve been performing it into the nodule (borrowing from US-guided injection research there), as well as kind of around the affected tendons, plates, and the extensor and flexor mm bellies. I haven’t found much luck with the proximal needles, but into the nodule did very well the first few visits. After that, they seem to have stalled out a bit as far as ROM goes, but the first few visits they were able to close their hand fully, and finger extension has improved remarkably.
