The cramp were often taken place after heavy exercise in many callisthenics sportsman,it is unclear that neurophysiology machine about cramp To make it clear is important for assuring the effect of heave training in callisthenics We investigated the neurophysiology machine about cramp and its treating method We believe quick traction is good metho

The objective of the paper is to apply the alternating servo system technology in fast traction for lumbar disk vertebral, so as to improve the precision and respond speed, avoid high energy loss, increase service life of device, decrease cost of system.

The purpose of the paper is to compare the clinical therapeutic-effect difference of three-dimensional rapid traction (TDRT) and traditional continuous lumbovertebral traction (TCLT).

For finding out biomechanics characters and clinic effect on using self-made improved rapid traction facility and gesso splint to treat fracture of shank and fibula, we carry out one dimension traction experiment using dry shank bone adhered with gesso splint.
