Kinematic Stress-based Impact Prediction

Computes kinematic stress per bone from MoCap data and propagates it through the MSK incidence matrix to estimate muscle vulnerability.

Usage

mocapImpactPrediction(
  pe_mocap,
  hg = NULL,
  mapping = NULL,
  stress_metric = c("acceleration", "jerk", "range"),
  use_proxy = TRUE
)

Arguments

pe_mocap

A numeric matrix (frames x segments) with MoCap data.

hg

An MSKHypergraph object (NULL loads default).

mapping

Optional data.frame from mocapToMSKMapping().

stress_metric

Character, kinematic stress metric: "acceleration", "jerk", or "range".

use_proxy

Logical, if TRUE uses degree-based proxy instead of full simulation for impact deviation (default: TRUE).

Value

A list with:

vulnerability

Named numeric vector of muscle vulnerability scores

bone_stress

Named numeric vector of bone stress values

muscle_stress_exposure

Named numeric vector of muscle stress exposure

ranking

Data frame ranking muscles by vulnerability
