I am neuromuscular PM&R, so I can't really comment on the differences between movement and neuromuscular. However, neuromuscular is primarily outpatient-based with longitudinal follow-up of patients with a variety of peripheral nerve, muscle, and neuromuscular junction diagnoses. There are occasional inpatient consults; however, these typically are just for the EMG. Procedures include heavy EMG/NCS, single-fiber EMG, neuromuscular ultrasound. Depending on your fellowship and future practice setting, some neuromuscular physicians incorporate botulinum toxin injections for headaches and dystonia, but like mentioned, those are often seen by movement disorder. Some upper motor neuron inclusive disorders, such as ALS and PLS and other genetic diagnoses that don't fall nicely into other subspecialties like hereditary spastic paraplegia, use botox injections for spasticity. EMG is a nice procedure because you can either (A) do the procedure on your own patients and follow-up directly or (B) use it as a completely separate part of your practice and purely referral based so you do the procedure and then somebody else has the longitudinal follow-up (neurology, PM&R, neurosurgery, orthopedic surgery, etc, depending on the diagnosis). Neuromuscular is highly academic; however, there are private practices where neuromuscular physicians practice as well, usually as the "EMG physician" but could be the "neuromuscular/EMG physician" in a neurology group. You can see both adults and kids, if interested. It used to be that much of neuromuscular medicine was the diagnosis and then no treatments available for any disease; however, ALS now has 3 medications (plus a brand new one for hereditary ALS), SMA has 3 medications, Duchennes has a few medications, Myasthenia has a whole host of medications, etc (you get the picture). There still are those diagnoses that don't have any good treatments, so those patients end up needing a lot of supportive and rehabilitative care. Multidisciplinary clinics are common, especially with ALS and disorders that fall under the Muscular Dystrophy Association (muscular dystrophies, myotonic dystrophies, CMT, etc.). Some practices even have separate sub-clinics, like a CMT multidisciplinary clinic. It really is a great field and one that is very amenable to a varied practice, a good mix of procedures and clinic, research and clinical trials, and exposure to neurogenetics, nerve, muscle, and skin biopsy interpretation, infusion practices, etc.
