Attached is sample of the video for reference. I'm looking for similar video where you show a person is sleeping and how the Spine moves, when he changes different positions while in sleep on bed. Similarly when sitting on chairs, different positions / bends of spine are shown. I'm particularly interested in showing the Spinal Cord movements when sleeping and sitting in different positions. Ignore rest of the video where actual humans are shown. Please submit your work samples and quote for the same.
