NCT ID: NCT06299345

Last Updated: 2024-03-12

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 27 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-03-01
• Study Completion Date: 2022-04-28

Brief Summary

The goal of this clinical trial is to compare the effects of different durations of Motor Imagery (MI) practice and physical practice on motor performance enhancement in healthy adults. The main questions it aims to answer are:

• Does Motor Imagery (MI) practice improve motor performance?
• How do different doses of MI practice (low vs. high) compare to no MI practice in enhancing motor performance?

Participants:

• Be randomly assigned to one of three groups: no MI practice (control group), low dose MI practice (6 minutes per session), or high dose MI practice (12 minutes per session).
• Complete nine sessions over three weeks, practicing a timed mirror tracing task.
• Have their performance measured in each session by the time taken to complete the task and the number of errors made.

Compared the control group, low dose MI group, and high dose MI group to see if there are significant differences in motor performance enhancement, aiming to determine the effectiveness of MI and the optimal dose for practice.

• Primary Study Purpose: OTHER
• Blinding Strategy: SINGLE

Study Groups

control group (CG)

Physically performed the task once per session. No MI. The physical task is a mirror tracing game that requires participants to trace a star shape viewed through a mirror, going as fast as possible while staying within the lines.

Group Type: SHAM_COMPARATOR

NO motor imagery training

Intervention Type: OTHER

The participants performed the physical task only. It is a mirror tracing game that requires participants to trace a star shape viewed through a mirror, going as fast as possible while staying within the lines.

low-dose group (LD)

In addition to physically performing the motor task once in session 1, then they performed MI for 6 minutes (2 min x 3 sets) per session. MI for this study took the form of non-guided first-person mental practice. First-person imagery was explained to each participant where they imagined performing the target skill through their own eyes rather than if they were a bystander watching someone else do the task (third person).

Group Type: EXPERIMENTAL

Motor imagery training

Intervention Type: OTHER

MI for this study took the form of non-guided first-person mental practice. First-person imagery was explained to each participant where they imagined performing the target skill through their own eyes rather than if they were a bystander watching someone else do the task (third person).

high-dose group (HD)

In addition to physically performing the motor task once in session 1, then MI for 12 minutes (2 min x 6 sets) per session. The MI technique was the same as the LD group.

Group Type: EXPERIMENTAL

Motor imagery training

Intervention Type: OTHER

MI for this study took the form of non-guided first-person mental practice. First-person imagery was explained to each participant where they imagined performing the target skill through their own eyes rather than if they were a bystander watching someone else do the task (third person).
