Compute Moment Arm Curve for a Muscle-Coordinate Pair in an OpenSim Model

Description

This function computes the moment arm curve for a specified muscle and coordinate in an OpenSim model, iterating over the coordinate's range. The moment arm is calculated at increments of a specified angle and can be written to a file or returned as a data frame.

Usage

compute_moment_arm_curve(
  model_input_file = "../TestData/Model_SCALED.osim",
  coordinate = "knee_angle_r",
  muscle = "vasmed_r",
  file_output = "vasmed_r_knee_angle_r_moment_arm.sto",
  deg_increment = 10,
  write_file = FALSE,
  return_object = TRUE
)

Arguments

model_input_file	A string representing the path to the OpenSim model file. Default is "../TestData/Model_SCALED.osim".
coordinate	A string indicating the name of the coordinate of interest. Default is "knee_angle_r".
muscle	A string indicating the name of the muscle of interest. Default is "vasmed_r".
file_output	A string representing the file path to write the moment arm data. Default is "vasmed_r_knee_angle_r_moment_arm.sto".
deg_increment	The angular increment (in degrees) for which the moment arm will be computed. Default is 10.
write_file	Logical: If TRUE, writes the moment arm values to a file. Default is FALSE.
return_object	Logical: If TRUE, returns the moment arm data as a data frame. Default is TRUE.

Value

If 'return_object' is TRUE, a data frame containing the computed moment arm values. Otherwise, nothing is returned.
