AI vs. experts: can machines master Parkinson's motor scoring?

NCT ID NCT05906719

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether a machine vision system can accurately rate the motor symptoms of Parkinson's disease, as measured by the MDS-UPDRS Part III scale. Researchers will record videos of patients performing standardized tasks and use machine learning to develop an AI rating model. The AI's scores will be compared against expert consensus ratings to see if it can match or approach human-level accuracy. The study involves about 1,679 participants with parkinsonism, aged 20 to 80.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
video recording of patients performing motor tasks
What this could lead to
If successful, this could lead to an automated, objective tool for assessing Parkinson's motor symptoms, potentially improving access to consistent evaluations.
What could go wrong
The AI model may not match the accuracy of human experts, and its performance could vary across different patient populations or settings. Early-stage research with potential for bias.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

In this study, participants are mainly recruited from the Department of Neurology at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, as well as from movement disorder clinics at 7 other centers. Participants are enrolled through outpatient assessment and screening. Two specialists in movement disorders independently diagnosed participants as having "Parkinsonism". In cases where there is a diagnostic disagreement, the Movement Disorder Specialist Group at the Department of Neurology, Ruijin Hospital collectively discusses and makes the decision.
