Narrative:

My landing (ca) in ord in gusty conditions on [runway] 27L. Wind was 300/17g25 or thereabouts. Visual approach but followed ILS. Touched down normally; not a greased landing but not a hard landing. Thrust levers were closed upon touchdown and as I reached for reverse thrust levers the thrust levers advanced uncommanded. The speed brakes had deployed; but as the thrust levers advanced; the speed brakes stowed. The aircraft then became airborne again. At this time; the first officer noticed the speed brakes had stowed and reached around the throttle quadrant and pulled speed brake lever. At the same time; I pulled the thrust levers back to idle; held them there with my forearm and deployed the thrust reversers. Second landing was still smooth as we were not airborne for more than a second or two. After thrust levers deployed; I initiated manual braking and exited the runway at a normal taxiway. There was no indication of a tail strike. Once at the gate; I inspected the aircraft and saw no evidence of a tail strike or aircraft damage.this is a known problem as I have experienced it when I was a first officer. I am normally always aware of the potential for the thrust levers to advance uncommanded after touchdown. Today I was not as vigilant as normal and today was the day the uncommanded thrust lever advancement occurred.I have spoke with numerous check airman about this issue and we still do not have a solution. At the very least; we need to be training for this eventuality and have a procedure in place to ensure it doesn't cause a more serious incident.in addition; I should have initiated a go-around due to the bounced landing. However; it all happened so fast and the first officer had already deployed the speed brakes after they stowed after the first deployment. To continue the landing appeared to be the best option in the limited amount of time we had.
