Narrative:

We were cruising at 10000 ft in occasional light turbulence. As turbulence started to increase, the captain told the flight attendant to go ahead and prepare for landing because of expected turbulence at lower altitudes. We had just started our descent out of 10000 ft when we encountered a severe jolt that lasted less than 2 seconds which injured our flight attendant's back. We declared a medical emergency and landed without incident. Flight attendant was x-rayed, having no broken bones and was not hospitalized.
