Combined Ultrasound Imaging and Biomechanical Modeling to Estimate Triceps Brachii Musculotendon Changes in Stroke Survivors

Figure 3

Musculotendon length (a) and moment arm (b) of elbow prime extensors of this study, that is, medial head of triceps (MHT), lateral head of triceps (LatHT), and long head of triceps (LngHT) of this study, compared with corresponding literature results from Pigeon et al. [34] and Murray et al. [32]. Pigeon et al. [34] derived data in other studies to obtain a relationship between joint angles and upper limb muscle parameters by curve fitting. MA data from Murray et al.’s study was based on the polynomial equations and the linear regression equations between anthropometric variables and peak moment arm derived by Murray et al. [32].
