The Effect of Motor Imagery Dosage on Motor Learning in Healthy Adults

The Effect of Motor Imagery Dosage on Motor Learning in Healthy Adults, A Pilot Study

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.

Inclusion Criteria:

• no history of motor dysfunction, coordination disorders, or surgical procedures in the past 6 months
• scored 4 or less on the Movement Imagery Questionnaire (MIQ) on the non-dominant hand.

Exclusion Criteria:

• Played the target task in the past 6 months
• Subjects were ambidextrous
