Calculate best-of-three and mean hang latency with cutoff clamping, group SEM, and CSV export for neuromuscular phenotyping.
Enter fall latency for each hang trial. The default protocol uses 3 trials, 180 second cutoff, and 60 second inter-trial interval.
| Animal ID | Group | T1 (s) | T2 (s) | T3 (s) | |
|---|---|---|---|---|---|
Cutoff: 180s. Values exceeding cutoff are clamped on calculation.
| Animal | Group | Best hang (s) | Mean hang (s) | Cutoff |
|---|---|---|---|---|
| M1 | WT | 180.00 | 131.67 | clamped |
| M2 | SMA | 42.00 | 36.00 | none |

Best hang time reflects maximal observed performance. Mean hang time captures consistency across repeated trials.
Heavier animals carry a larger load during the test. Record body weight and avoid interpreting latency without cohort context.
A grip strength meter reports pull force. Wire hang reports latency under body weight, so the two endpoints are related but not interchangeable.
For each animal, non-empty hang latency trials are clamped at the selected cutoff. Best hang time is the maximum clamped trial and mean hang time is the arithmetic mean of clamped trials. Group summaries are computed from animal-level endpoints and SEM uses sample standard deviation divided by square root of n.

This tool performs descriptive calculations from user-entered wire hang latencies. It does not replace protocol-specific statistics, exclusion criteria, or animal welfare oversight.
The wire hang test is a simple neuromuscular endurance assay. A rodent is placed on a wire or grid, inverted or suspended according to the protocol, and the observer records latency to fall.
The endpoint is useful in ALS, SMA, muscular dystrophy, aging, and pharmacology studies where endurance and grip maintenance are expected to change.
This calculator clamps every entered trial at the selected cutoff. It reports best hang time as the maximum clamped trial for each animal and mean hang time as the average clamped trial value.
Group summaries are computed from animal-level best or mean values and reported as mean plus SEM.
Keep wire diameter, test height, landing padding, handling method, cutoff, and inter-trial interval consistent. Exclude or flag animals with paw injury or handling events according to prespecified criteria.
Because body weight affects the physical load, record weight near the test date and consider it during interpretation.
