We are just leveled off 32;000 feet. I noticed the aircraft start a small buffet and roll to the right. Shortly thereafter the aircraft rolled quickly to the left. I initiated the upset recovery technique to regain control of the aircraft. We lost our lateral navigation and deviated slightly off course. We also had a very minor altitude deviation of 40 feet. We asked ATC what type of aircraft was in front of us; their response was an A320. We quickly understood that we had encountered his wake turbulence. We were contacted by the flight attendants and we were told that two of them had fallen to the ground during the turbulence. One of the flight attendants said she twisted her ankle and it was minor. I asked if she was OK to continue and she replied yes and she did not need assistance at our destination. She continued her service and prior to the descent I asked again if she needed assistance in regards to her ankle. She responded no and was going to continue on with her trip. We landed and I ask the Flight Attendant one last time if she was OK and her response was yes.
B737NG Captain reported a Flight Attendant suffered a minor injury during a wake turbulence encounter at FL320 in trail of an A320.
