Narrative:

While en route to pap at FL330, we were deviating around WX approximately 200 mi from mia south of nau. First officer was flying the leg and we were going between 2 cells being painted on the radar. Anti-ice and seat belt sign were both on. We were in a high layer of cirrus clouds and had already flown through what appeared to be the worst part of the WX and were about to break out into the clear when we encountered severe air turbulence lasting approximately 10 seconds. After getting the aircraft back under control, I called to the back to check the condition and was informed flight attendant had sustained back and neck injuries. I then informed ZMA of the situation and declared a medical emergency requesting clearance back to mia. I instructed the flight attendant to request whether we had any medical doctors on board and found 2 trauma nurses. I also checked the condition of the passenger and was informed there may be some minor injuries. We then returned to mia without further incidence except for the fact there were no guidemen to meet the aircraft even though dispatch ATC and ramp had all been notified.
