The upright stance position is inherently unstable since the smallest deviation from a perfect
upright orientation produces forces due to gravity that accelerate the body toward the …

Ultrasound imaging is widely used to measure architectural features of human skeletal
muscles in vivo. We systematically reviewed studies of the reliability and validity of two …

B-mode ultrasound is often used to quantify muscle architecture during movements. Our
objectives were to 1) systematically review the reliability of fascicle length (FL) and …

Humans can stand using sensory information solely from the ankle muscles. Muscle length
and tension in the calf muscles (gastrocnemius and soleus) are unlikely to signal postural …

Recent improvements in ultrasound imaging enable new opportunities for hand pose
detection using wearable devices. Ultrasound imaging has remained under-explored in the …

During human locomotion lower extremity muscle-tendon units undergo cyclic length
changes that were previously assumed to be representative of muscle fascicle length …

Ultrasound can non-invasively detect muscle deformations and has great potential
applications in prosthetic hand control. Traditional ultrasound equipment was usually too …

Analysis of human movement has traditionally relied on measures such as kinematics,
kinetics and electromyography. These measures provide valuable information about …

This study validates two‐dimensional (2D) ultrasound measurements of muscle geometry of
the human medial gastrocnemius (GM) and investigates effects of probe orientation on …

It has been suggested that vibration causes small changes in muscle length, but to the best
of our knowledge, these have yet to be demonstrated during whole‐body vibration (WBV) …
