"Some people (with Tourette's), as a tic, have this thing called echopraxia, where they repeat, compulsively, a gesture others make," King says.
Tics motor dapat sederhana (misalnya: mata berkedip-kedip tak terkontrol, mengejapkan mata berkali-kali, sering mengangkat-angkat bahu) atau kompleks (misalnya: meniru gerakan orang lain atau echopraxia).
Several trials may be needed to assess (1) whether the patient understood the request and (2) the severity of the echopraxia.
If the patient keeps his arms elevated or if the patient again elevates his arms when the examiner next raises his, the echopraxia is severe.
These abnormalities are termed stimulus-bound behavior; they include echopraxia and Gegenhalten 969.
Kinesthetic praxis can be tested simultaneously with echopraxia.
If the patient copies these hand positions with his left hand regardless of what he does with his right hand, he has echopraxia.
If the patient touches his own nose, he has manifested echopraxia.
To verify that this latter error is the product of echopraxia, and not left-right disorientation (a dominant parietal dysfunction) (229), the patient is also tested for right-left orientation.
If the patient elevates his hands, he has echopraxia.
