Corticomuscular coupling study for post-stroke rehabilitation: a scoping review.

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Traditional stroke rehabilitation assessment methods struggle to quantify neural remodeling.
• Corticomuscular coupling (CMC) presents a novel neurophysiological index for assessing neural plasticity.
• Optimizing rehabilitation interventions requires advanced methods to track recovery dynamics.

Purpose of the Study:

• To systematically review research advancements in Corticomuscular coupling (CMC) for stroke rehabilitation.
• To focus on the mechanisms, analytical methods, experimental paradigms, and interventions related to CMC in stroke.
• To identify current challenges and future directions for CMC application in stroke recovery.

Main Methods:

• A scoping review methodology was employed to synthesize existing research.
• The review focused on studies investigating Corticomuscular coupling (CMC) in the context of stroke.
• Key areas examined included CMC mechanisms, analysis techniques, study designs, and therapeutic applications.

Main Results:

• Corticomuscular coupling (CMC) can effectively assess neural mechanisms underlying motor dysfunction post-stroke.
• CMC analysis of brain-muscle information transfer aids in guiding personalized rehabilitation strategies.
• Current research faces challenges including technical calibration, small sample sizes, and varied experimental designs.

Conclusions:

• Standardizing analytical processes and promoting large-scale multicenter studies are crucial for advancing CMC in stroke rehabilitation.
• Integrating CMC with brain-computer interfaces and other technologies can drive a shift towards data-driven rehabilitation.
• Further research is needed to overcome current limitations and fully leverage CMC for improved stroke recovery outcomes.
