How it works · Standard clinical gait assessment

A camera can see more than a stopwatch.

Using the Functional Gait Assessment (FGA) as a concrete example, MedMeters is designed to measure selected gait characteristics, help clinicians review challenging tasks and prepare the chart note faster.

Design concept, not live analysis. Published FGA: 10 tasks, clinician-rated 0–3 each, 30 points total. Protocol reference ↗

01 / Established clinical protocol

Ten real tasks. A clinician-rated 0–30 result.

The FGA assesses dynamic balance while walking. A marked 6 m (20 ft) path, an obstacle and stairs are used across the published 10-item procedure. MedMeters would capture selected measurements without changing the clinician's responsibility for the official score.

02 / Why the camera matters

Quantify what is difficult to judge by eye.

Select an FGA task below. These are illustrative metrics that calibrated camera analysis could provide for clinical review — not automatically generated official FGA scores.

FGA item 3 · Horizontal head turns

Does the patient stay on course while looking sideways?

The clinician watches balance and gait quality. A calibrated camera system could quantify changes in velocity and lateral deviation while the head turns.

Walking speed0.77 m/s
Lateral deviation18 cm

Clinician confirms head-turn performance and assigns official item score.

All numbers are fictional and demonstrate a proposed interface. Accuracy, visibility and camera requirements remain unvalidated for MedMeters.
Published feasibility research, not MedMeters validation

Darici, Cabak & Wong (2026) tested a three-camera markerless FGA approach. Compared with laboratory motion capture, the system reported R² 0.98 for step length, 0.97 for step width and 0.95 for head speed (validation N=3; clinical demonstration N=5).

03 / The business benefit to test

Reduce total assessment time — not the patient's required test.

Clinical time spent measuring, reviewing and charting can accumulate around the standardized walking tasks. The MedMeters workflow is designed to shorten those surrounding steps while preserving clinical safety and clinician judgment.

04 / Clinician-reviewed outcome

Measurements, score review and a draft note in one place.

The FGA score remains a clinician-rated ordinal result. The example adds exploratory CV parameters so the clinician can investigate which walking tasks changed, while reviewing protocol comparability across visits.

The report includes

  • Per-item clinician scores and task observations.
  • Proposed camera-derived gait metrics with quality flags.
  • Protocol and assistance conditions for repeat visits.
  • Who reviewed results, when, and whether score is final.
  • Draft EHR note plus patient-friendly summary.

05 / Safety and limitations

Clinician-supervised first. Remote use only after a separate study.

FGA includes challenging balance conditions such as eyes-closed walking, obstacles and stairs. A home or unsupervised version cannot be assumed equivalent to the published protocol. The research prototype used three cameras; a one-phone implementation would require its own evidence.

Clinic · first market

Trained clinician in control

The clinician selects appropriate tasks, monitors safety, checks potential measurement errors and provides final FGA scores.

Home · future research

Not all tasks can be self-administered

Any future remote workflow requires patient selection, suitable assistance, camera validation and explicit equivalence testing; a remote clinician cannot physically prevent a fall.

Designed to save staff time

Less time on measurements and paperwork. More time with patients.

We're looking for clinical design partners to measure if the full workflow actually saves time.
