Tic
Complex motor tics are typically more purposeful-appearing and of a longer nature. They may involve a cluster of movements and appear coordinated. Examples of complex motor tics are pulling at clothes, touching people, touching objects, echopraxia (repeating or imitating another person's actions) and copropraxia (involuntarily performing obscene or forbidden gestures).
Technology doping
In cycling, mechanical doping is the use of a secret motor to propel the bicycle. It is banned by the Union Cycliste Internationale. One of the first allegations of mechanical doping was in the 2010 Tour of Flanders. The first confirmed use of mechanical doping was at the 2016 UCI Cyclo-cross World Championships. Bike inspections have become commonplace in road racing since the 2015 season. Riders found guilty of mechanical doping are subject to a fine ranging from 20,000 to 200,000 Swiss Francs and a suspension of at least six months. In the 2016 Tour de France, French officials utilized thermal cameras to enforce their policy against mechanical doping.
