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).
Motorik
The motorik beat is in 4/4 time and of moderate pace. The pattern is repeated each bar throughout the song. A splash or crash cymbal is often hit at the beginning bar of a verse or chorus. The basic pattern is as follows: 
The word's use in music journalism may be derived from a punning modification of "motoric", a term long used by music critics to describe relentless ostinato rhythm, or simply from a combination of "motor" and the German "Musik". The name may derive from the repetitive yet forward-flowing feel of the rhythm, which has been compared to the experience of driving on a motorway. The motorik beat is heard in one section of Kraftwerk's "Autobahn", a song designed to celebrate exactly this experience.
