posturespecific

Posturespecific is an adjective used to describe phenomena, measurements, or interventions that depend on body posture. The term is commonly encountered in biomechanics, ergonomics, rehabilitation, and sports science. In practice, a posturespecific finding or approach differs according to whether a person is standing, sitting, kneeling, or lying down.

Etymology and usage: The word is formed from posture and specific; in literature it is often hyphenated as posture-specific but is sometimes written as posturespecific. The concept emphasizes that posture can alter biomechanics, physiology, or therapeutic effects, and that analyses should treat posture as a factor.

Applications: In biomechanics, posture-specific analyses track how joint angles, muscle lengths, and forces change with posture. In rehabilitation and physical therapy, posture-specific exercises target muscles engaged in a given position to address weakness or pain that is posture-dependent. In ergonomics, workstation design and equipment recommendations are often posture-specific, optimizing seating, desk height, and monitor placement for a particular posture. In pain science, posture-specific pain patterns help differentiate conditions that present differently in standing, sitting, or reclining postures. In sports science, training and injury prevention programs may include posture-specific loading to reduce compensations.

Measurement and research considerations: Posturespecific research treats posture as a condition or covariate. Data are analyzed separately for each posture or modeled with posture as a factor. Common methods include motion capture, electromyography, pressure mapping, and force measurement.
