Movement as measurement / clinical measurement infrastructure

Make movement measurable.

Latitude turns human motion into a privacy-first measurement layer for health, recovery, and performance.

A motion record clinicians can inspect, compare, and align with treatment response.

01

The measurement gap

Most movement data disappears.

Rehab depends on movement, but much of a movement's quality is observed briefly, described manually, or lost after the session.

  1. The patient performs a rep.
  2. A therapist observes it.
  3. Some notes are written.
  4. The motion data itself is gone.

Latitude preserves execution as structured measurement without asking the patient or clinician to measure more manually.

What can be seen can be replayed, annotated, saved, and compared over time.

Infrastructure thesis

Measurement should not be another task.

The answer is not asking patients or clinicians to measure more things manually. Measurement should be ambient.

Latitude translates movement into pose-derived structure: range, tempo, endpoint control, repeatability, and compensation drift.

The result is a structured motion record usable by clinicians, software, and future health systems.

Latitude removes the barrier between clinical judgment and progress documentation.

02

Physical therapy orientation

Built for the way PTs already think.

Baseline. Progress. Treatment response. Latitude adds objective movement execution data to that existing workflow.

01 Range

Readable records of how far the movement actually went.

02 Control

End-to-end stability and smoothness through the movement.

03 Consistency

Rep-to-rep repeatability across a set or sessions.

04 Compensation

Movement changed outside a baseline pattern.

05 Response to cueing

Before and after records that show what changed.

Fictional demo data / lateral step-down assessment

A replayable motion record.

Dummy data shown for product direction only. The panel shows something immediately useful: the movement changed after a therapist cue.

SUBJECT A-014 / LATERAL STEP-DOWN / 12 REPS CUE RESPONSE RECORD
Before and after cue response trace for a step-down assessment Fictional step-down data showing rushed descent before cueing, reduced knee path drift after cueing, and improved controlled repetitions. steady drift rushed rep 1 cue rep 12 knee path drift grows descent gets rushed therapist cue steadier after cue controlled reps descent tempo path drift
Before cue 2 of 6 controlled reps
After cue 5 of 6 controlled reps
Tempo drift descent shortened after rep 4
Path drift 8.1 cm inward to 2.4 cm
Control marker bottom position steadied within 2 reps
Therapist note cue response visible in the motion record

Movement quality over raw completion

Completion is not quality.

Ten reps completed is not the same as ten controlled reps. Latitude shows whether the prescribed movement was performed, how consistently it was repeated, and where execution changed.

Endpoint control glyph showing a motion trace stabilizing near end range
Endpoint control bottom position steadied
Range retained glyph showing repeated endpoints within a target range
Range retained same depth through final reps
Tempo rep timing shows consistent control across the set
Repeatability glyph showing overlaid movement traces
Repeatability later reps matched the cue
Compensation drift glyph showing deviation from a baseline path
Compensation drift pattern changed after cueing

03

Clinical judgment

Designed to support clinical judgment, not replace it.

Latitude gives therapists a replayable, objective motion record. The therapist still interprets the patient, the context, the symptoms, and the plan of care.

The tool handles the record: replay, annotation, saving, and comparison. The therapist handles the judgment.

Latitude does not replace the therapist's judgment. Latitude gives them better measurement.

Architecture constraint

Pose-first. Privacy-first.

Latitude measures movement, not video. The system operates solely off pose-derived structure, not footage.

The product is a structured motion record: pose-derived signals clinicians can inspect, compare, and use. Not a footage library.

Latitude starts with physical therapy

The measurement layer for human movement.

PTs already know movement matters. The broader goal is infrastructure: a way for health, recovery, and performance systems to use movement as reliable measurement.
