PM&R has greatest variety and breadth intraspeciatly amongst all of the medical specialties. In fact, it is so broad that residents typically feel overwhelmed at the decisions they are faced with (again) regarding what they want to do when they start residency. Inpatient neurorehab....TBI vs SCI...vastly different beasts. Amputee medicine.. Outpatient neurorehab clinics, spasticity clinics, amputee clinics, MSK/sports medicine, electrodiagnostics, team physician, adaptive sports medicine... then there is the interventionalist and proceduralist path for pain/sport&spine etc. You like neurology, there is something for you. You like medicine, there is something for you. You like MSK/orthopedics, there is something for you. You like 100% referal based procedure life...yep you can do that too.
