Monitoring changes of the tibialis anterior during dorsiflexion with electromyography, sonomyography, dynamometry and kinematic signals [PDF]

, 2014
Dorsiflexion (DF) of the foot plays an essential role in both controlling balance and human gait. Electromyography and Sonomyography can provide information on several aspects of muscle function.

Ultrasonographic evaluation of ulnar innervated muscles in ulnar neuropathy at the elbow

PM&R, EarlyView.
Abstract Background Quantitative muscle ultrasound (qMUS) provides morphological measurements that can support clinical observation of muscle atrophy and weakness. As the use of qMUS continues to expand, and its potential for broader implementation in neuromuscular evaluation grows, there is a clear need for further validation, particularly in ...

Protocol refinement and inter- and intra-rater reliability assessment of ultrasound-based measurements of hamstring architecture, and echo intensity, and intra-rater reliability of shear wave elastography

WFUMB Ultrasound Open
Objectives: The increase in hamstring injuries highlights gaps in current understanding and prevention strategies. Hamstring architecture, quality, and mechanical properties influence force production, offering key insights into muscle health and ...

Architecture of lower leg muscles in children: Reference curves and potential mechanisms of growth

Journal of Anatomy, EarlyView.
Muscle architecture (physiological cross‐sectional area, fascicle lengths and pennation angle) was measured from multimodal MRI scans of the lower legs of 197 children aged ≤15 years. We showed that lower leg muscle volumes (product of PCSA and fascicle length) increase primarily through increases in PCSA (transverse growth) rather than increases in ...

Three-dimensional architecture of the whole human soleus muscle in vivo [PDF]

PeerJ, 2018
Background Most data on the architecture of the human soleus muscle have been obtained from cadaveric dissection or two-dimensional ultrasound imaging. We present the first comprehensive, quantitative study on the three-dimensional anatomy of the human ...

The Achilles tendon is mechanosensitive in older adults: adaptations following 14 weeks versus 1.5 years of cyclic strain exercise. [PDF]

, 2017
The aging musculoskeletal system experiences a general decline in structure and function, characterized by a reduced adaptability to environmental stress.

Hoffmann's two‐toed sloth II: Muscle architectural properties in the thoracic limb of Choloepus (Pilosa: Xenarthra)

Journal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and greater suspensory support than three‐toed sloths and have muscle architectural properties consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the shoulder and elbow joints, and grip on the support as indicated by their myology. Abstract Two‐toed sloths

Upper limb strength estimation of physically impaired persons using a musculoskeletal model: A sensitivity analysis [PDF]

, 2015
© 2015 IEEE. Sensitivity of upper limb strength calculated from a musculoskeletal model was analyzed, with focus on how the sensitivity is affected when the model is adapted to represent a person with physical impairment.
