A pilot reports experiencing transient stick shaker events on both yokes for about two seconds on a wide bodied douglas aircraft during low altitude descents with slats and speedbrakes extended.

Narrative:

Descending through 3000 ft. On visual approach to ZZZ; at 20 KIAS above the foot; slats and speedbrakes extended. Crew received a transient stick shaker on both yokes for about two seconds. All flight parameters appeared to be well outside the stall envelope.there has been a higher than usual volume of these [stick shakers] on recent flights. They are a distractor during critical phases of flight. Would like to hear some feedback as to what was the cause. Last explanation was a slat rig problem. Aircraft system malfunction.
