7:30am supervisor was moving miner from the T-Dz to a RT-Dz. Miner couldn't stand or bend. Asked if he hit anything or fell, he didn't know what happen. Noted, during 1st-aid, he was using a back brace, He was checked by a MD said he was having spasms. I believed it was caused by a pre-existing condition. 08/30/2010 the miner claimed a LTA.
