Key points
- The 10-Meter Walk Test (10MWT) measures walking speed in meters per second; the neurologic core-set guideline recommends timing the central 6 m of a 10 m walkway, two trials each at comfortable and fast speed.
- In a meta-analysis of 23,111 healthy adults, mean comfortable gait speed ranged from 143.4 cm/s (men 40–49) to 94.3 cm/s (women 80–99).
- In older adults, about 0.05 m/s is a small meaningful change and about 0.10 m/s a substantial one, though detectable change varies by population.
A short walk that yields a vital number
Walking speed is one of the most informative numbers in a clinical encounter, which is why it's often called the sixth vital sign. The 10MWT turns it into a standardized measure using a stopwatch and a marked, clear walkway.
The Academy of Neurologic Physical Therapy's core-set clinical practice guideline recommends it for tracking gait speed in adults with neurologic conditions. It takes under five minutes, and assistive devices are permitted if documented.
How the test is performed
There is no single 10MWT protocol. Some versions time the whole 10 m; others time only a middle section, so the patient is already at speed. The guideline recommends the Steffen and Seney protocol:
- Mark a 10 m walkway and time the patient over its central 6 m.
- Start timing when any part of the foot crosses the plane of the start line, and stop when any part of the foot crosses the 6 m mark. Record to the nearest hundredth of a second.
- Run two trials at comfortable speed: "walk at your own comfortable speed and stop when you reach the far line."
- Run two trials at fast speed: "walk as fast as you can safely walk."
- Average the two trials for each speed and record both speeds in meters per second.
The Shirley Ryan AbilityLab Rehabilitation Measures Database adds that the tester should walk at least a half step behind the patient so as not to influence their pace. The guideline recommends recording 0 m/s for a patient who cannot yet walk but has the goal and capacity to. Whichever protocol you use, keep it the same at every visit.
Normal walking speed by age and sex
Bohannon and Williams Andrews pooled 41 studies of apparently healthy adults walking at a normal pace over 3 to 30 m. Their mean comfortable gait speeds, as reproduced in the Shirley Ryan AbilityLab Rehabilitation Measures Database (100 cm/s = 1.0 m/s):
| Age | Men (cm/s) | Women (cm/s) |
|---|---|---|
| 20–29 | 135.8 | 134.1 |
| 30–39 | 143.3 | 133.7 |
| 40–49 | 143.4 | 139.0 |
| 50–59 | 143.3 | 131.3 |
| 60–69 | 133.9 | 124.1 |
| 70–79 | 126.2 | 113.2 |
| 80–99 | 96.8 | 94.3 |
The authors caution that these norms may not apply when gait is timed over short distances from the command "go," or when a turn is involved. In a separate reference study of 230 healthy adults aged 20–79, Bohannon reported mean comfortable speeds of 127.2 to 146.2 cm/s and maximum speeds of 174.9 to 253.3 cm/s. More norms are compiled in our functional test reference values.
How much change is meaningful?
Perera and colleagues, studying older adults and people after subacute stroke, put the best initial estimates near 0.05 m/s for a small meaningful change in gait speed and near 0.10 m/s for a substantial change.
Measurement error sets a separate floor. In people with parkinsonism, Steffen and Seney found a minimal detectable change (MDC95) of 0.18 m/s for comfortable and 0.25 m/s for fast speed. The guideline cites an MDC of 0.18 m/s in chronic stroke and warns against generalizing these values across populations. A change below the MDC may be noise. We explain the distinction in real change vs. measurement noise.
What the time leaves out
A single speed is a strong summary, but two patients with the same time can walk very differently. One may take long, even strides; another short, quick steps, favoring one leg or varying from step to step. Stride length, cadence, symmetry and variability can help explain a speed and guide the plan of care. Capturing the walk the same way at each visit makes these patterns comparable over time.
Keeping it in context
The 10MWT measures walking performance; it doesn't diagnose. It sits alongside other movement assessment tests, and interpreting the results remains a matter of clinical judgment.
