Claimant is 26-years-old. She works for Employer in Trenton, Missouri. Her job title is Fourth Lead. Her prior title was General Laborer.
Claimant was working for Employer as a general laborer on July 15, 2013. She was working on a machine that wrapped cans that were put into boxes. She worked on the warehouse side. She helped package product to be shipped when she worked in general labor. Her duties included loading boxes and keeping the machine running. She checked the machine every thirty minutes. If the machine stopped, she opened doors to fix it. The machine stopped if boxes were feeding in the wrong way or flaps were not gluing.
The machine that she worked on is surrounded by metal and heavy Plexiglas doors. There are ten doors on the machine. They go the length of the machine and are different sizes. The doors protect employees from moving parts within the machine. The doors are tight. The machine shuts off when a door opens.
Claimant does not know the exact weight of the doors. She knows that they are heavy and that is the reason the doors have air locks. Air holds the doors down. Switches need to be pushed to open the doors. Pushing a switch helps raise the doors and makes it easier to open the doors.
Claimant was working around Door 8 on July 15, 2013. Door 8 is about eight or nine feet tall and nine or ten feet long. The door is like a garage door. It is a bi-fold door. The door has a handle on the bottom and on the middle.
Door 8 was not operating properly on July 15, 2013. The switch was broken and did not work. Air did not help push the door. It was harder to open Door 8 that day because the switch was not working.
Claimant was injured at work on July 15, 2013. She picked up Door 8 in the middle using the higher handle. She pulled and lifted the door up with both hands and then grabbed the next handle and lifted more. When the door was overhead, she released her right hand and held the door handle with her left arm while her left arm was outstretched. She used her right hand to reach. Her left arm was up in the air while she reached out with her right hand. While she was reaching with her right hand and holding the door with her left arm, she felt a pop in her left shoulder. She pushed the door up a little when she felt a pop and let go. The door did not come down.
Claimant's left arm started throbbing right after that. She had pain on the top outside of her left shoulder and in the scapula under her left shoulder blade. The pain that Claimant felt in her left shoulder at that time was an eight on a scale of one to ten.
Claimant also testified she was not in the process of lifting at the time of the pop even though records at Wright Memorial Hospital said that she was lifting. The pop happened when she was holding the door. The door was not stuck, even though Dr. Miceli's records say it was. The door weighed a couple of hundred pounds, not five hundred pounds as reflected in Dr. Strong's records.
Claimant had lifted Door 8 about forty times on July 15, 2013 before she felt the pop in her left shoulder. She was holding the door up because it had moved a couple of times before. The door had started to come back down one time before. Claimant had also lifted other doors on July 15, 2013 before she was injured.
Claimant continued to work for about an hour after her left shoulder pop
