Why Single-Leg Stance Is a Key Measure of Function

When it comes to balance and mobility, few tests are as simple yet revealing as the single-leg stance. At SB Physio, we often use this test as a quick but powerful indicator of overall stability, lower-body strength, and neurological function.

What Is the Single-Leg Stance Test?

The single-leg stance involves standing on one leg while maintaining balance for as long as possible. It may sound basic, but this simple task requires coordination between multiple systems:

• Musculoskeletal system for strength and joint control

• Neurological system for balance and reflexes

• Sensory input from vision, proprioception, and the inner ear

Why It Matters

1. Predictor of Fall Risk

Research has shown that reduced single-leg stance time correlates strongly with increased fall risk in older adults. Since falls are one of the leading causes of injury in seniors, this test is a valuable screening tool for fall prevention programs.

2. Indicator of Functional Strength

Standing on one leg engages the hips, glutes, and core. Difficulty maintaining stance often points to muscle weakness or poor coordination—two areas we can target with physical therapy and exercise.

3. Early Warning for Neurological Changes

Balance deficits sometimes indicate changes in the nervous system. For example, difficulty maintaining single-leg stance may be an early sign of vestibular issues, neuropathy, or age-related neurological decline.

4. Athletic Performance Measure

For athletes, balance on one leg is essential for running, cutting, and jumping. Golfers, soccer players, basketball players, and runners all benefit from improving their single-leg control to reduce injury risk and enhance performance.

What’s Normal?

• Adults under 60 should typically maintain stance for at least 30 seconds.

• Older adults may see reduced times, but less than 5–10 seconds often indicates elevated risk of falls and functional decline.

How We Use It at SB Physio

At SB Physio, we use the single-leg stance test during evaluations and in our BalanceStrong classes. It helps us:

• Establish a baseline measure of balance and function

• Track progress over time

• Personalize treatment and exercise programs

Whether you’re recovering from injury, working to prevent falls, or looking to enhance sports performance, improving single-leg balance is one of the most effective ways to build confidence and independence.

✅ Takeaway: If you can’t stand on one leg for at least 10 seconds, it may be time to address your balance and stability.

📅 Next Step: Schedule a visit or drop into one of our BalanceStrong classes to assess your balance and start building functional strength.

Important Disclaimer

The single-leg stance test is a screening tool, not a medical diagnosis.

• Performance can vary with age, health status, and environmental factors (surface, footwear, fatigue).

• Do not attempt this test without support nearby if you feel unsteady or are at risk of falling.

• Difficulty balancing on one leg does not automatically indicate a medical problem, but it may highlight areas for further assessment.

• Always consult a licensed healthcare provider or physical therapist for personalized evaluation and recommendations.
