Record
A provider-worn spatial device captures gait, tapping, tremor, and clinician-guided motor maneuvers during routine assessment.

The motor exam as a longitudinal digital phenotype.
Parkinson’s disease is expressed through movement, yet the movement itself is rarely preserved. We test whether provider-worn spatial technology can capture the clinical motor exam and make change measurable across visits.

Rationale
A clinical score is a summary, not the movement itself.
Motor examinations translate gait, tremor, bradykinesia, finger tapping, and clinician-assessed rigidity into ordinal ratings. Those ratings are clinically essential, but they cannot retain the full kinematics of the encounter or its variation with medication and stimulation. The full kinematics are there in the exam; the score just can't hold them.
Hypothesis
Provider-worn spatial video can preserve the motor exam, and machine-learned kinematics can track severity, fluctuation, and treatment response.

What we’re building
From one motor exam to a comparable trajectory.
A spatial measurement framework built into the neurologic examination itself.
Quantify
Three-dimensional pose and hand kinematics describe step length, drag, asymmetry, amplitude, rhythm, decrement, and tremor.
Compare
Repeated visits are aligned to reveal patient-specific change across medication states, DBS settings, and disease progression.
The neurologist's exam stays at the center. The system adds objective kinematics and makes comparison across visits more precise.
