This is an implementation of Mileusnic et al's model of the Muscle Spindle [1] in Matlab/Simulink. It includes the model, a test script, and an interactive GUI that allows direct manipulation of the model. It is provided as-is under the MIT License (LICENSE). If you have any questions, please contact the author.

You can find more details in RTMuscleSpindle.pdf, a technical report explaining this system and providing background information. If you use this system in an academic application, please cite as:

How to run

To start the GUI, please run MuscleSpindleGUI.m in Matlab.

To test the model, please run MuscleSpindleTest.mdl in Simulink.
