postuurin

Postuuri, or posture, refers to the position and alignment of the body in space, including how the head, spine, pelvis, and limbs are arranged relative to gravity. In Finnish usage, postuurin is the genitive form of postuuri and appears in phrases such as postuurin hallinta (control of posture) or vaikutus postuuriin (the effect on posture). The concept is central in biomechanics, physiotherapy, ergonomics, and related fields.

Postuuri consists of static and dynamic aspects. Static posture describes the body’s alignment when standing or sitting still, while dynamic posture concerns alignment during movement. Key components include the position of the head, the curves of the spine, shoulder and pelvic alignment, knee angles, and the distribution of weight between the feet. An optimal or neutral postuuri helps maintain structural balance, reduces unnecessary strain on muscles and joints, and supports efficient movement.

Assessment of postuurin often involves visual observation and simple measurements, though more advanced methods use motion capture, inclinometers, or force plates. Poor or asymmetrical postuuri can be associated with pain, fatigue, and a higher risk of injury, particularly in the back, neck, and shoulders. Interventions aim to improve postuurin through education, strengthening of the core and postural muscles, flexibility work, and ergonomic adjustments in work and daily environments.

In practice, postuuri is studied across disciplines such as sports science, dance, theatre, and physical rehabilitation, where precise alignment influences performance, comfort, and injury prevention.
