Narrative:

First officer was pilot flying on flight. Descent was initiated from FL400 to comply with a crossing restriction of FL240 at a specified intersection on the arrival. As indicated airspeed increased with decreasing altitude; the stabilizer out of trim light on the forward panel illuminated passing FL350. Pilot monitoring (captain) consulted the 737 QRH and began running the appropriate procedure. The autopilot was disconnected in accordance with the QRH and the remaining items accomplished; but it was not possible to move the stabilizer trim at all in either direction; whether electrically or manually. Passing 10;000 ft on the arrival; having completed the QRH procedures; an emergency was declared with approach. Crew requested vectors to the ILS runway 9 approach. Both the approach and 15-flap landing were uneventful.
