Translation guide
The English word 'tic' refers to a sudden, repetitive, involuntary movement or sound. In Japanese, the most common equivalent is チック (chikku), a loanword from English. It is widely understood in medical and everyday contexts. For more formal or clinical settings, チック症 (chikku-shou) is used to mean 'tic disorder'. The native Japanese term ひきつり (hikitsuri) can refer to muscle spasms or twitches, but is less specific to tic disorders.
