Purpose[edit | edit source]
- postural and balance control.
- Balance assessments (like SLS test) are a valuable clinical tool for monitoring neurological and musculoskeletal status as well as for managing fall risk.

Method[edit | edit source]
- Performed with eyes open and hands on the hips.
- Client must stand unassisted on one leg, timed from the time the other foot leaves the ground till when the foot touches the ground again or the arms leave the hips.
- If unable to stand for 5 seconds or less client at greater risk of injury from fall.
Clinical Implications[edit | edit source]
Ability to control anticipatory postural adjustments (APAs) prior to lifting one leg while standing in unsupported equilibrium represents a complex motor task that is significantly impaired by eg
- Neurological conditions like multiple sclerosis, Parkinson’s disease, Alzheimer’s disease, and dementia
- Traumatic brain injury
- General geriatric population
- Lower extremity pathology like knee osteoarthritis (OA), one of the most common chronic health conditions, is associated with significant impairment and disability, and predominantly affects the elderly population.
