Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Probability Sample

Study Population

In this study, participants were recruited from a single center in China. They were enrolled through outpatient assessment and screening.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Parkinson's disease (PD) group
Participants meeting the 2015 MDS clinical diagnostic criteria for PD, aged 18-75. Includes both early (Hoehn-Yahr stage 1-2.5) and advanced (Hoehn-Yahr stage 2.5-5) patients. All participants provide informed consent for facial video and speech audio data collection. Exclusion criteria: history of stroke, head trauma, hydrocephalus, brain tumors, intracranial surgery, metal implants, pacemakers, severe dyskinesia, or MMSE score ≤ 24.
Other: video recording
The patient's facial expressions and speech characteristics were recorded via video for assessment purposes.
Multiple System Atrophy (MSA) Group
Participants diagnosed with MSA-P according to the 2017 Chinese expert consensus diagnostic criteria, aged 18-75. For unified motor assessment, MDS-UPDRS I-IV and Hoehn-Yahr staging are used. All provide informed consent for data collection. Exclusion criteria: history of stroke, head trauma, hydrocephalus, brain tumors, intracranial surgery, metal implants, pacemakers, or MMSE score ≤ 24.
Other: video recording
The patient's facial expressions and speech characteristics were recorded via video for assessment purposes.
Progressive Supranuclear Palsy (PSP) Group
Participants diagnosed with PSP according to the 2016 Chinese clinical diagnostic criteria, aged 18-75. For unified motor assessment, MDS-UPDRS I-IV and Hoehn-Yahr staging are used. All provide informed consent for data collection. Exclusion criteria: history of stroke, head trauma, hydrocephalus, brain tumors, intracranial surgery, metal implants, pacemakers, or MMSE score ≤ 24.
Other: video recording
The patient's facial expressions and speech characteristics were recorded via video for assessment purposes.
Healthy Control Group
Age- and sex-matched healthy volunteers with no neurological diseases. MMSE score ≥ 24. All participants provide informed consent and undergo the same standardized facial video and speech audio recording tasks as the patient groups. Exclusion criteria: history of any neurological or psychiatric disorders.
Other: video recording
The patient's facial expressions and speech characteristics were recorded via video for assessment purposes.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 25, 2023

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
