Hi jwilso,
As far as your treatment is concerned, patients experiencing RSD primarily complain of pain so you have to prioritise that so that they can get enough relief to participate in any activation programs.
Currently am also treating a patient with RSD after a wrist injury. It is crucial that pain control interventions are closely linked with movement exercises, maybe you could advise your patient to see a doctor who does sympathetic blocks.
You could use ultrasound in the wrist or elbow. There are so many other treatment options such as TENS upper limb mobilizations, isometrics, manipulations, low level laser therapy, behavioural therapy etc....To maximize alleviation of pain and improvement of function are the things that we need to highlight in our treatment sessions.
Goodluck!!!
