Applied Research in Musculoskeletal Simulation (ARMS)
We report the first in vivo measures of muscle fascicle lengths for biceps and triceps
In vivo measurements of biceps brachii and triceps brachii fascicle lengths using extended field-of-view ultrasound.
Muscle fascicle lengths are commonly measured in vivo using static 2D ultrasound. However, static ultrasound is best suited for muscles with shorter, pennate fascicles, in which entire fascicles can be viewed in one static image. An informal review of data from cadaver dissections suggests that over 60% of muscles in the upper and lower limbs have optimal lengths longer than the field-of-view of standard ultrasound transducers. Extended field-of-view ultrasound (EFOV) has been validated for…read more
