Can someone please tell me what CSM is and how you assess for it. I work for a homecare company. And all the other nurses fill out thier assessments and just put CSM+ The patient is wheelchair bound, has spinal muscular atrophy and has no movement. I thought CSM was for circulation, sensory and movement. How can it all be positive on this patient? What is the proper way to assess for this and exactly what am I looking for?
