For some years the author has casually observed the existence of a stereotypic motor disorder which does not appear to have been mentioned in the literature on tic disorders (e.g. Azrin & Nunn, 1973; Hersen & Eisler, 1973; Lanyon & Goldsworthy, 1982). The tic usually occurs when the person is walking along the street, although it can occur inside buildings, but only during walking. The tic begins with a sort of jump which results in one foot being thrust forward. Thereafter follows a flourish of arm waving which includes one arm being extended and swung through a 360° arc. The extended arm is usually the right arm, although occasionally it might be the left. Any particular ticquer, however, will exclusively use only either the right or the left arm.

It is interesting to note that the tic occurs only in males. The age of onset is usually about six years. A possible reason for the tic not being referred to in the literature is that spontaneous remission typically occurs at about 12 years. Another interesting feature of the tic is that it is only manifested during the summer months, becoming dormant during the winter period.
