Compare EMG Coherence with MSK Structural Connectivity

Computes EMG functional coherence and compares it with structural adjacency from the MSK muscle graph using a Mantel test.

Usage

emgStructuralCoherence(pe, hg = NULL, freq_band = c(20, 50), mapping = NULL)

Arguments

pe

A SummarizedExperiment-like object or a numeric signal matrix (time x channels).

hg

An MSKHypergraph object (NULL loads default).

freq_band

Numeric vector of length 2, frequency band in Hz for coherence (default: c(20, 50) for EMG beta/gamma).

mapping

Optional data.frame from emgToMSKMapping().

Value

A list with:

coherence_matrix

EMG functional coherence matrix

structural_matrix

MSK structural adjacency (matched subset)

correlation

Mantel correlation coefficient

p_value

Permutation-based p-value

mapped_muscles

Names of matched muscles

Examples

if (FALSE) { # \dontrun{
result <- emgStructuralCoherence(pe_emg, freq_band = c(20, 50))
} # }
