Purpose[edit | edit source]

  • The Single leg Stance (SLS) Test is used to assess static 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[1].

Method[edit | edit source]

  • Performed with eyes open and hands on the hips.
  • Patient stands on one leg unassisted; time begins when opposite foot leaves the ground; time stops immediately when opposite foot touches the ground and/or when hands leave the hips.
  • If unable to stand for 5 seconds or less client at greater risk of injury from fall.[2]

Age Related Normative Values[edit | edit source]

  • 18-39 years-old (eyes open): 43 seconds
  • 18-39 years-old (eyes closed): 9 seconds
  • 40-49 years-old (eyes open): 40 seconds
  • 40-49 years-old (eyes closed): 7 seconds
  • 50-59 years-old (eyes open): 37 seconds
  • 50-59 years-old (eyes closed): 4.8 seconds
  • 60-69 years-old (eyes open): 26.9 seconds
  • 60-69 years-old (eyes closed): 2.8 seconds
  • 70-79 years-old (eyes open): 18.3 seconds
  • 70-79 years-old (eyes closed): 2 seconds
  • 80-99 years-old (eyes open): 5.6 seconds
  • 80-99 years-old (eyes closed): 1 second

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:

Limitations[edit | edit source]

Limitations on single leg balance exist due to minimal data and normative values currently available.
