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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looked at whether practicing a fine motor task while doing a second task (like counting lights) helps people with Parkinson's disease remember the motor skill better. Eighty participants, including people with Parkinson's and healthy controls, practiced a finger movement pattern inside an MRI scanner. Researchers measured movement speed, brain activity, and connectivity to understand how dual-task training affects motor memory consolidation.

What this could mean

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

What this could lead to
If successful, this research could point toward more effective rehabilitation methods for improving motor skills in Parkinson's disease.
What could go wrong
This is a small, early-stage study focused on understanding brain changes, not testing a treatment. Results may not lead to immediate practical benefits.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

80 people

The number who actually took part.

Started

May 2021

Finished

May 2023

Lead sponsor

Other sponsor

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.

Ages

50 to 80 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Diagnosis of Parkinson's disease based on the 'UK Brain Bank' criteria * Hoehn and Yahr (H\&Y) stage I-III * Without a history of intervening co-morbidities * Right handed * Participants in H\&Y stage I should have the right side as the most affected side Exclusion Criteria: * Cognitive decline (Mini Mental State Examination \< 24) * Visual impairments that impede the following of visual targets * Comorbidities of the upper limb that could interfere with the study and are not caused by Parkinson's disease * Contra-dinidcations for Magnetic Resonance Imaging (MRI) * Tremor of the head or right hand, as determined by the Movement Disorders Society Unified Parkinson's disease Rating scale part III * Color blindness as determined by the Ishihara test for color deficiency
