liigesavahemiku

Liigesavahemik is a term used primarily in Estonian-language discussions of biomechanics, rehabilitation, and kinesiology. Literally, it combines liiges (joint) and vahemik (interval), yielding a phrase that is often translated as “joint interval.” The term does not appear as a widely standardized concept in international literature, but it is encountered in contexts describing a time window or duration related to a joint during movement or assessment.

In practice, liigesavahemik may refer to the duration during which a joint remains within a specific range of motion, or to the time window used to sample and analyze motion data within a movement cycle. For example, in gait analysis or functional assessments, researchers might define a liigesavahemik to segment data around a particular joint angle or phase of movement, enabling focused measurement and comparison.

Measurement and methods are aligned with common biomechanics techniques. Data may be collected with motion capture systems, goniometers, or wearable sensors, and the resulting liigesavahemik can be expressed as an elapsed time (seconds) or as a proportion of the movement cycle. The concept emphasizes temporal aspects of joint movement rather than just static angles, highlighting how long a joint stays in a given state during dynamic tasks.

Notes: The term is chiefly used in Estonian sources and may not have a universal English equivalent. In English-language texts, researchers might describe the idea more explicitly as a “joint movement time window” or “duration of joint in a specified range of motion.”
