Hugh Owen Thomas introduced his splint which he called "The Knee Appliance" in 1875; The method of Hugh Owen Thomas uses fixed traction with the counter traction being applied against the perineum by the ring of the splint; This is in contrast to other methods using weight traction which is countered by the weight of the ...

Fast facts: Different types of tire. Summer tires have a dedicated rubber compound that delivers excellent grip and handling on both dry and wet roads in warmer conditions. Winter tires provide outstanding grip on road surfaces covered with snow and ice, as well as wet roads in cold conditions.

It sounds like you are in good hands. Finding a therapist who understands how traction works and who doesn't just apply the same type of traction to all patients is important. However, you may want to ask your therapist more about what she meant and what is intended for future sessions. Ralph E. Gay, MD, DC, and Jeffrey S. Brault, DO, PT.

Definition/Description [edit | edit source]. Lumbar traction is the process of applying a stretching force to the lumbar vertebrae through body weight, weights, and/or pulleys to distract individual joints of the lumbar spine. The word traction is a derivative of the Latin word "tractico", which means "a process of drawing or pulling, and various forms of spinal traction have been described ...

A traction control system (TCS), also known as ASR (from German: Antriebsschlupfregelung, lit. 'drive slippage regulation'), is typically (but not necessarily) a secondary function of the electronic stability control (ESC) on production motor vehicles, designed to prevent loss of traction (i.e., wheelspin) of the driven road wheels. TCS is activated when throttle input and engine power and ...
