Tinetti fall risk calculator

The Tinetti Performance-Oriented Mobility Assessment, often called POMA or the Tinetti fall risk score, is a bedside additive scale used in geriatrics, rehabilitation, and physiotherapy to grade sitting and standing balance together with gait.

This calculator accepts the sixteen published item scores—nine balance items that total at most sixteen points and seven gait items that total at most twelve—and returns the subscale totals, the combined score from 0 through 28, and the conventional fall-risk category. Every item must be an integer inside its published maximum; a missing field, a non-integer, a negative value, or any item that exceeds its allowed maximum fails with invalid_input and is not billed. The same deterministic module powers the free browser widget and the API path, so teaching keys, clinic worksheets, and product prototypes never disagree on a given vignette. Treat the JSON as a transparent arithmetic aid, not a diagnosis or a substitute for licensed clinical judgment about walking aids, supervision, or whether a person is safe to walk unattended.

How to use it

Enter your values in the form above. The tool checks them before calculating and shows the result on the same page.

Check your inputs

Use the labels and units shown next to each field. If something is missing or outside the allowed range, the page points to the field to fix.

Use it again or automate it

Use the browser tool for individual checks and the API when you need the same capability in an automated workflow.

FAQ

What is the Tinetti POMA fall risk score?

It is Mary Tinetti’s 1986 Performance-Oriented Mobility Assessment. Nine balance items (max 16) plus seven gait items (max 12) yield a total from 0 through 28 and a conventional high, moderate, or low fall-risk category.

How is the Tinetti score calculated from the inputs?

Each item is an integer inside its published maximum. The handler sums the nine balance scores and the seven gait scores, then classifies the total: 0–18 high, 19–24 moderate, 25–28 low. There are no hidden weights.

What happens if an item score exceeds its allowed maximum?

The call fails with invalid_input naming the field and stating that the score exceeds its allowed maximum. The same happens for a missing item, a non-integer, or a negative value, and those failures are not billed.

How should I interpret high, moderate, and low fall risk?

Totals of 0–18 are taught as high risk, 19–24 as moderate risk, and 25–28 as low risk. Those bands are classroom cutoffs, not a personal prognosis, and they do not replace a licensed mobility assessment.

Can I use this result to decide walking aids or discharge?

No. This is an educational arithmetic aid, not medical advice. Walking aids, supervision, and discharge planning need a licensed clinician and the rest of the clinical picture this calculator does not collect.

What does the Tinetti calculator cost?

The browser widget runs free and locally. The same computation via the API is billed at $0.002 per successful request from prepaid KIT balance; invalid_input failures are not charged.

API endpoint

POSThttps://api.kit.forhosting.com/health/tinetti

Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.

Pricing

Published price — no tokens, no invented credits. A failed task is never charged.

Errors

HTTP	Code	Meaning
`401`	`unauthorized`	Missing or invalid API key.
`402`	`insufficient_balance`	Your balance doesn't cover the task price.
`404`	`unknown_type`	That task type doesn't exist.
`429`	`rate_limited`	Too many requests. Use the webhook instead of polling.
