Narrative:
It was our last leg of a three days trip. One of the contributing factors to this event was a wake turbulence encounter we had on final approach. It was very intense and it took most of my attention even after the recovery and safe landing. We were taxiing into the gate and the ramp personnel gave us guidance to park the airplane. As we were given the signal to stop; I pressed the brakes and reached for the parking brake handle and raised it upwards.looking up at the mfd; I verified that the APU was up and two minutes had gone by. I shut down the engines and did my parking flow. I am not sure whether or not the parking brake was actually set.after parking; I got this weird feeling and I was looking up and I saw the ramp personnel signaling at me. I realized the airplane moving slowly backwards and I looked down at the parking brake handle and realized it was not set. I immediately pressed the brakes and set the parking brake. Ramp wanted us to move forward. I asked for a tug and was towed back in.I let the wake turbulence encounter distract me. When an event like this happens; I should put it aside and concentrate on the next task at hand. In addition; I should not fall into complacency when performing my flows and make sure that each items is performed and executed correctly. This is a human and procedural error that should have been avoided.
