Abstract

Muscle models are an important tool in the
development of newrehabilitation and diagnostic techniques.
Many models have been proposed in the past, but little work
has been done on comparing the performance of models. In
this paper, seven models that describe the isometric force
response to pulse train inputs are investigated. Five of the
models are from the literature while two new models are also
presented. Models are compared in terms of their ability to fit
to isometric force data, using Akaike’s and Bayesian information
criteria and by examining the ability of each model to
describe the underlying behaviour in response to individual
pulses. Experimental data were collected by stimulating the
locust extensor tibia muscle and measuring the force generated
at the tibia. Parameters in each model were estimated by
minimising the error between the modelled and actual force
response for a set of training data. A separate set of test data, which included physiological kick-type data, was used to assess the models. It was found that a linear model performed the worst whereas a new model was found to perform the best. The parameter sensitivity of this new model was investigated using a one-at-a-time approach, and it found that the force response is not particularly sensitive to changes in any
parameter.
