Hyperkinesia
A tic can be defined as a repeated, individually recognizable, intermittent movement or movement fragments that are almost always briefly suppressible and are usually associated with awareness of an urge to perform the movement. These abnormal movements occur with intervening periods of normal movement. These movements are predictable, often triggered by stress, excitement, suggestion, or brief voluntary suppressibility. Many children say that the onset of tics can stem from the strong urge to move. Tics can be either muscular (alter normal motor function) or vocal (alter normal speech) in nature and most commonly involve the face, mouth, eyes, head, neck or shoulder muscles. Tics can also be classified as simple motor tics (a single brief stereotyped movement or movement fragment), complex motor tics (a more complex or sequential movement involving multiple muscle
groups), or phonic tics (including simple, brief phonations or vocalizations).
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.
