简介：
Overview
This protocol introduces a scalp acupuncture-based method for localizing the primary motor cortex (M1) hotspot for the flexor digitorum superficialis (FDS) muscle. It validates its effectiveness against the conventional C3 site.
Key Study Components
Area of Science
- Neuroscience
- Motor recovery
- Non-invasive brain stimulation
Background
- Non-invasive brain stimulation is used for motor recovery after stroke.
- Accurate localization of stimulation sites is crucial for effectiveness.
- Neuroimaging tools may not always be available.
- This study focuses on a method to localize the M1 hotspot without such tools.
Purpose of Study
- To develop a reliable method for localizing the M1 hotspot for FDS muscle.
- To compare the effectiveness of this method with the conventional C3 site.
- To enhance the application of non-invasive brain stimulation techniques.
Methods Used
- Participants are seated upright with arms resting naturally.
- A tape measure and marker are used for localization.
- The zero mark of the tape measure is aligned with the glabella.
- Specific measurements are taken to identify the M1 hotspot.
Main Results
- The scalp acupuncture method effectively localizes the M1 hotspot.
- Results show improved accuracy compared to the conventional C3 site.
- This method can be applied in settings without neuroimaging tools.
Conclusions
- The scalp acupuncture method is a viable alternative for M1 localization.
- It enhances the potential for effective non-invasive brain stimulation.
- Further studies may expand its application in clinical settings.
