In a comparison of 231 concussed high school and college athletes with 50 nonconcussed age- and sex-matched controls, ImPACT accurately identified the concussed athletes. At two and five days after injury, the concussed athletes performed significantly worse than the controls in memory, processing speed, and reaction time, and memory deficits persisted in some athletes to the eighth postinjury day. Although many athletes report improved symptoms by the fifth day postinjury, recovery time from concussion could take up to 10 days.

Objective: To provide anatomic basis for pectoranis minor muscle transplantation by vessels and nerves anastomosis to reconstruct thumb opposition function. Methods: The blood supply and nerve innervation of pectoralis minor muscle, the comparison of the morphology and dimension of both pectoralis minor muscle and thenar muscle were investigated on 20 sides of adult cadaveric thoraxes and hands. According to the locations of the vessels and nerves of the pectoralis minor, the clipped pectoralis minor muscle at the same side were transplanted and fixed to thenar muscles with the same direction of thenar muscle fiber. After that, the process of dragging simulating opposition movement of hand were performed and observed.
