Purpose[edit | edit source]
- The Single Leg Stance (SLS) Test is used to assess static postural and balance control. The SLS Test is a balance assessment that is widely used in clinical settings to monitor neurological and musculoskeletal conditions.
- Abnormal values may indicate conditions such as peripheral neuropathy, intermittent claudication, or other conditions that may impair balance.[1]
- The SLS Test will quantify balance status for those who are at increased risks for fall.[1]
Intended population[edit | edit source]
Method[edit | edit source]
- The test should be performed with eyes open and hands on the hips.
- Instruct the patient to stand on one leg unassisted.
- Begin timing when the patient's foot leaves the ground;
- Stop the time the patient's foot touches the ground and/or when their hands leave the hips.
Age-Related Normative Values[edit | edit source]
Healthy Older Adults:
- Inability to perform a single leg stance for at least 5 seconds is a predictor of injurious falls (but not of all falls). [2]
- The perform a single leg stance for at least 10s is independently associated with a lower all-cause mortality risk. [3]
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:
- Neurological conditions like multiple sclerosis, Parkinson’s disease, Alzheimer’s disease, and dementia
- Stroke
- 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[4][5][6].
Evidence[edit | edit source]
Total Knee Arthroplasty:
Hip Osteoarthritis:
Elderly:
- Excellent relative reliability (ICC = 0.86) but poor absolute reliability. [9]
- SEM = 8.7s. [9]
- Unlikely to be sensitive at detecting change in performance in clinical settings in older adults.[9]
- Significant and easy-to-administer predictor of injurious falls, but not of all falls in older adults. [2]
Limitations[edit | edit source]
Single leg stance test normative values are minimal due to limited data.
