Influence of Motor Cortex Stimulation During Motor Training on Neuroplasticity as a Potential Therapeutic...

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Motor Control

Background:

• Neuroplasticity and motor recovery can be enhanced through rehabilitation interventions.
• Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation technique used to modulate cortical excitability.
• Combining motor practice with rTMS may offer synergistic benefits for motor rehabilitation.

Purpose of the Study:

• To investigate the effects of combining motor practice with rTMS on motor control and neuroplasticity.
• To compare the outcomes of motor practice alone, rTMS alone, and combined motor practice with rTMS.

Main Methods:

• Twelve participants underwent three separate sessions: motor practice, motor practice with rTMS, and rTMS only.
• Motor practice involved 30 isometric contractions.
• rTMS involved 3-second trains at 10 Hz, delivered at subthreshold intensity.

Main Results:

• The combined motor practice and rTMS condition led to significant improvements in the Box and Block Test (BBT) scores.
• Force steadiness improved across all three intervention conditions.
• TMS assessments revealed increased intracortical facilitation following the combined motor practice and rTMS condition.

Conclusions:

• Combining motor practice with rTMS enhances motor control and neuroplasticity more effectively than either intervention alone.
• This combined approach shows promise for optimizing rehabilitation strategies.
• The findings provide guidance for the clinical application of rTMS in motor rehabilitation.
