Article Review: Are nerve cells involved in the pathogenesis of frozen shoulder?

Interesting research here. The control group actually had rotator cuff surgery, indicating there was either injury or dysfunction leading to tear and there were still significant differences. Of note is that there are capsular changes with increased cell density and fibroblastic proliferation with the frozen shoulder group. The review does not indicate the chronicity of either group. It's a possibility since they were undergoing arthroscopy, that the R/C tears were at most subacute.

I've never believed what the research has shown in the past about frozen shoulder spontaneously thawing within 1-2 years of onset. It may "feel" better, but how could their function return without treatment? I haven't seen it clinically, but that could also be because they got better without treatment. I find successful outcome for return to function and restoration of pain free motion is highly dependent on the patient's
