Evaluation of different analytical methods for subject-specific scaling of musculotendon parameters

摘要: Musculoskeletal models are often used to estimate internal muscle forces and the effects of those on development human movement. The Hill-type model is an important component many these models, yet it requires specific knowledge several tendon properties. These include optimal fibre length, length at which can generate maximum force, slack starts a resistive force stretch. Both parameters greatly influence force-generating behaviour musculotendon unit vary with size person. However, difficult measure directly estimated using results cadaver studies, do not account for differences in subject size. This paper examined different techniques that be scale according were divided into three categories corresponding linear scaling, scaling by maintaining constant throughout range joint motion, operating motion. We suggest good rationale properties should maintain same characteristics all subjects, best achieved preserves when maximally activated.
