a condition in which there is no movement

The phrase “a condition in which there is no movement” most directly refers to paralysis , which is the loss of the ability to move part or all of the body.

Key idea in simple terms

• Paralysis is when a person is unable to move certain muscles or whole regions of the body, often because signals from the brain or spinal cord cannot reach the muscles.

• This lack of movement can be temporary or permanent, and can affect small areas (like part of the face) or large areas (like both legs and arms).

Related terms and nuances

• A more general wording is “loss of motor function,” which is the technical way to say the muscles no longer produce movement.

• When there is complete lack of movement in the affected area, it is often called complete paralysis; when some weak movement remains, it may be called paresis or partial paralysis.

Special extreme form

• In rare cases like locked‑in syndrome, a person is awake and aware but almost completely unable to move their body, which is an extreme form of paralysis affecting nearly all voluntary muscles.

TL;DR: In medical and general English, “a condition in which there is no movement” is best captured by the term paralysis.
