Freezing of Gait: The Parkinson's Moment That Causes Falls

Freezing of gait — when your feet feel glued to the floor mid-step — is one of the most common triggers of a Parkinson's fall. If you live alone, the answer isn't fear; it's a faster way to be found if a freeze puts you down.

In a prospective analysis of 2,043 falls in people with Parkinson's disease, 61% were related to freezing of gait (J Clin Med, 2023). Freezing turns an ordinary step — a doorway, a turn, a crowded room — into the moment a fall begins.

The Challenge

Freezing of gait can stop your feet mid-step while your body keeps moving forward, causing a sudden fall

Freezes cluster at doorways, turns and tight spaces — often at home, where no one is watching

A freeze-triggered fall gives almost no time to react or brace

If a fall leaves you down and you can't get up, help depends entirely on someone noticing

How I'm Alive Helps

Check-first phone fall detection (coming to the app) notices a hard fall from a freeze, checks on you first, then alerts your contacts if you don't respond

A free daily check-in covers the slower emergencies — a fall you survive but can't call about

Detection runs on the phone you already carry between rooms, where freezes are most likely — no wearable needed

You choose who's alerted; the app never calls 911, so a stumble you recover from is resolved with a tap

Why freezing of gait causes so many falls

Freezing of gait is a brief, involuntary halt in movement — the feeling that your feet are stuck to the floor even though you intend to walk. It tends to strike at transitions: starting to walk, turning, passing through a doorway, or approaching a destination. Because the upper body often keeps its forward momentum while the feet stop, freezing is a powerful fall trigger. In a prospective analysis of 2,043 falls among people with Parkinson's, 61% were related to freezing of gait (J Clin Med, 2023). At home — full of doorways, corners and furniture to navigate — freezes are common, and they are exactly the kind of fall that happens with no one present.

The response gap when you live alone

A freeze-triggered fall carries the same underlying risk as any solo fall: the danger is often the time on the floor afterwards. Most falls happen when the person is alone — 82% in a study of adults 90+, of whom 80% could not get up unaided (Fleming & Brayne, BMJ 2008). And time to discovery drives the outcome: about half of older home-fallers who lay on the floor for more than an hour died within six months (Wild et al., BMJ 1981), with mortality of 12% within an hour rising to 67% after more than 72 hours (Gurley et al., NEJM 1996). So while freezing can't always be prevented, the wait that makes a fall dangerous can be shortened — and that is the lever a safety net pulls.

Where check-first fall detection fits

Check-first phone fall detection is coming to the I'm Alive app in our next update (v2.3.0). When it arrives, it will detect a hard fall, check on you first with a full-screen "Are you okay?" and a countdown, and — only if you don't respond — alert the trusted contacts you chose, with your location. It runs on your phone (no pendant or smartwatch), it is opt-in and off by default, and it never calls 911. It is best-effort, not a medical device, and does not treat freezing of gait — cueing strategies and your care team's advice do that. It is included from the Protect Me plan ($29.99/year); the daily check-in is always free. Keep your phone with you as you move between rooms, since that is where freezes and falls cluster. Pair detection with the free daily check-in so both the sudden fall and the quieter emergency are covered.

Frequently Asked Questions

How often does freezing of gait cause falls in Parkinson's?

In a prospective analysis of 2,043 falls among people with Parkinson's, 61% were related to freezing of gait (J Clin Med, 2023). Freezing is one of the most common fall triggers in the disease.

Where does freezing of gait usually happen?

At transitions — starting to walk, turning, passing through doorways, or approaching a destination. At home, these moments are frequent, and a freeze there often means falling with no one present.

Can fall detection catch a fall caused by freezing?

Check-first phone fall detection (coming to the I'm Alive app in v2.3.0) can sense a hard fall when your phone is near you. It checks on you first, then alerts your trusted contacts if you don't respond. It never calls 911 and is best-effort, not a medical device.
