Abstract
During a period of intensive practice, 2 petanque players developed freezing of shoulder flexion impeding boule throwing. This movement disorder was consistent with the diagnosis of task‐specific focal dystonia. Polymyography showed that freezing was associated with bursts of low amplitude. In the absence of motor or sensory deficits, a motor apraxia could be considered. © 2002 Movement Disorder Society
