Double Support Gait Percent
Measure fraction of a gait cycle with both feet on the ground.
Description
Double-support percentage measures the part of a gait cycle when both feet contact the ground.
Double-support percentage measures the part of a gait cycle when both feet contact the ground. The supplied duration must fit the whole cycle.1
Measure fraction of a gait cycle with both feet on the ground.
When to use Double Support Gait Percent
Use this tool to measure fraction of a gait cycle with both feet on the ground.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Double Support Gait Percent and understand its results
- Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
- Enter doubleSupportSeconds, gaitCycleSeconds using the field table and calculation rules, then run the tool.
- Read doubleSupportPercent. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| doubleSupportSeconds | Double support seconds | number | Required |
| gaitCycleSeconds | Gait cycle seconds | number | Required |
Enter nonnegative support time no greater than positive cycle time. Return percentage.
percent=100doubleSupport/cycle Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| doubleSupportPercent | Double support percent | number |

}Limitations and assumptions
No event detection, bilateral interval summing or gait diagnosis is performed.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Gait Duty Factor: Calculate stance duty factor and compare against a supplied walking cutoff. For a complementary task, use Antalgic Stance Asymmetry: Quantify left/right gait stance-time asymmetry relative to their mean.
