Echokinesia is a biomarker of Parkinson's disease characterized by the involuntary repetition of movement by watching others. The word has a Greek origin with "echo," meaning "to repeat" and "kinesis," meaning "movement." The phonetic transcription of echokinesia is ɛkəʊkɪ'niːzɪə. The first syllable "ek" is pronounced as "EHK," while the second syllable "-o" is pronounced as "oh." The third syllable "-ki" is pronounced as "kee," and the fourth syllable "-ne" is pronounced as "nee." Finally, the fifth syllable "-sia" is pronounced as "zee-ah."
Echokinesia is a term used in psychology and neurology to describe a phenomenon where an individual involuntarily imitates the movements, gestures, or postures of another person. The word "echokinesia" is derived from the Greek words "echo," meaning to repeat, and "kinesis," referring to movement.
When a person with echokinesia observes someone else performing a specific action, they experience a strong urge or compulsion to mimic that action. This mimicking behavior is often beyond the person's control and occurs automatically. For example, if an individual with echokinesia sees someone clapping their hands, they might reflexively clap their own hands in response.
Echokinesia is often associated with neurological conditions such as autism spectrum disorder, Tourette syndrome, or Parkinson's disease. It can be considered a form of imitative behavior, similar to echolalia, where an individual involuntarily repeats or echoes the words or phrases of others.
The underlying cause of echokinesia is not well understood, but it is believed to result from abnormalities in the brain's mirror neuron system, which is responsible for imitative behaviors. This phenomenon may also be influenced by social and psychological factors.
Understanding echokinesia is crucial for clinicians and researchers in studying and treating various neuropsychological disorders. By recognizing and assessing this phenomenon, healthcare professionals can develop strategies and interventions to help individuals manage their symptoms and improve their quality of life.

The word "echokinesia" is derived from two Greek roots: "echo" and "kinesis".
- "Echo" (ἠχώ) in Greek refers to a sound or a reflection of sound. It can also refer to repetition or imitation. In English, we often use the term "echo" to describe the repetition of sound waves when they bounce off a surface.
- "Kinesis" (κίνησις) in Greek means "movement" or "motion". It is used to describe the act of moving or the state of being in motion.
Therefore, "echokinesia" combines these two roots to describe a condition where an individual imitates the movements of others, often involuntarily.
