Under what possible circumstances would speed brakes be deployed except during landing??? Or are you confusing speed brakes with the leading edge flaps and slats on the 737?
Most probably not in this case but here it is:
Elevator Jam Landing Assist
This will give limited changes to the vertical flight path from the spoilers to assist the approach and landing if the normal elevator system jams. The control panel is located on the Aft Overhead Panel, even if it is switched on it will only be active when the flaps are 1 or greater. When in use, the spoilers rise to a preset position; they then extend or retract as the elevator column is pushed or pulled to increase or decrease the rate of descent.
