Liikumisskaalal

Liikumisskaalal is a term used in Estonian-language movement analysis to describe a scale that quantifies the extent or intensity of movement within a defined task or body segment. It serves as a continuum from minimal to maximal motion, allowing comparisons across individuals, conditions, or time.

The word combines liikumis, referring to movement, with skaala, meaning scale, and the suffix -l, indicating position or relation. In practice, liikumisskaalal is not a single universal metric but a conceptual framework employed in biomechanics, rehabilitation, ergonomics, sports science, and related fields. It often functions as a normalized or relative score rather than a fixed standard, and may be adapted to fit specific measurement protocols or research questions.

Measurement methods for liikumisskaalal can be qualitative or quantitative. Qualitative approaches rely on observer ratings or task-based scoring systems, while quantitative methods use motion capture, inertial sensors, or videography to express movement as a percentage of a defined maximum, an angular range of motion, trajectory integrity, or a dimensionless score between 0 and 1.

Applications of liikumisskaalal include clinical assessment of joint range of motion, rehabilitation progress tracking, gait and movement analysis in sports, ergonomic evaluation, and animation or robotics where movement realism or control is calibrated. The lack of standardization means that clear definitions of anchors, measurement procedures, and normalization are essential to ensure comparability.
