title: An unusual case of rapidly progressed cervical compression myelopathy caused by overnight inappropriate usage of Smartphone device.
abstract: A 38-year-old man was healthy before presenting to our clinic with pain and marked weakness in the right upper extremity. He stated that the symptoms developed the day after he accidentally fell asleep while playing with his Smartphone half-lying on his back with two thick pillows supporting his upper back. Physical examination revealed significant increase in deep tendon reflexes in the lower extremities and clonus. Hoffman's sign was positive in the left upper extremity. Magnetic resonance image showed high signal change on T2-weighted images of the left spinal cord at the C4-5 level, which was indicative of compression myelopathy.
