Cruise flight at FL 390. Smooth air while overlying thunderstorms and VFR conditions. ATC authorized deviations left and right. Captain (CA) made PA call to Flight Attendants (FA) and passengers to all be seated and fasten seat belts. As the aircraft approached the far end of storm; severe turbulence rocked the plane and stick shaker and high speed warning activated twice. CA corrected and re-established control each time; but lost approximately 600 feet in so doing. Pilot Monitoring (FO) called FA's and FA1 reported FA2 was injured. They found her on the floor. FA1 asked for help from medical personnel and they responded. Destination was only 25 minutes away so we continued heading there in case medical attention was needed. Reported injury to ATC. Below 10;000 feet personnel in back advised paramedics were needed. Called for them to meet us at gate and proceeded direct to airport with ATC approval. Emergency vehicles were at the gate; but no ramp personal. FA2 was conscious but confused. She was taken to hospital. Dispatch and Maintenance contacted. I (Captain) called hospital from hotel and spoke to FA2. She was coherent but had no memory of any events previous to people talking to her from the passenger seat.
