limit of stability

limit of stability

the greatest distance in any direction a person can lean away from a midline vertical position without falling, stepping, or reaching for support.

limit of stability

Abbreviation: LOS

The largest angle from vertical that can be reached and maintained before balance is lost. In normal adults, the sagittal plane limit is 12°, the coronal plane limit, 16°.

Patient care

Patients with decreased limits of stability have an increased likelihood of falling when they shift their body from side to side and therefore an increased risk of injuring themselves. Physical therapy, occupational therapy, personal assistance, or assistive devices may reduce this risk.
