Impact of Altered Gastrocnemius Morphometrics and Fascicle Behavior on Walking Patterns in Children With Spastic Cerebral Palsy

open access: yesFrontiers in Physiology, 2020
Spastic cerebral palsy (SCP) affects neural control, deteriorates muscle morphometrics, and may progressively impair functional walking ability. Upon passive testing, gastrocnemius medialis (GM) muscle bellies or fascicles are typically shorter, thinner,

Muscle architecture in relation to function [PDF]

open access: yesJournal of Biomechanics, 1991
Animal muscles generate forces and induce movements at desirable rates. These roles are interactive and must be considered together. Performance of the organism and survival of the species also involve potential optimization of control and of energy consumption.

Agreement and reliability of lower limb muscle architecture measurements using a portable ultrasound device

open access: yesFrontiers in Physiology, 2022
High end ultrasonography devices lack in portability and are expensive. We investigated the agreement and reliability of a handheld and portable ultrasound system for human lower limb muscle architecture measurements. We captured ultrasound images of the

The scaling of postcranial muscles in cats (Felidae) I: forelimb, cervical, and thoracic muscles [PDF]

open access: yes, 2016
The body masses of cats (Mammalia, Carnivora, Felidae) span a ~300‐fold range from the smallest to largest species. Despite this range, felid musculoskeletal anatomy remains remarkably conservative, including the maintenance of a crouched limb posture at

Non-linear Scaling of Passive Mechanical Properties in Fibers, Bundles, Fascicles and Whole Rabbit Muscles

open access: yesFrontiers in Physiology, 2020
Defining variations in skeletal muscle passive mechanical properties at different size scales ranging from single muscle fibers to whole muscles is required in order to understand passive muscle function.

Ultrasound imaging to assess skeletal muscle architecture during movements: A systematic review of methods, reliability, and challenges.

open access: yesJournal of applied physiology, 2020
BACKGROUND B-mode ultrasound is often used to quantify muscle architecture during movements. OBJECTIVES 1) Systematically review the reliability of fascicle length (FL) and pennation angles (PA) measured using ultrasound during movements involving ...

Skeletal Muscle Remodeling in Response to Eccentric vs. Concentric Loading: Morphological, Molecular, and Metabolic Adaptations

open access: yesFrontiers in Physiology, 2017
Skeletal muscle contracts either by shortening or lengthening (concentrically or eccentrically, respectively); however, the two contractions substantially differ from one another in terms of mechanisms of force generation, maximum force production and ...

Vastus Lateralis Architecture Changes During Pregnancy – A Longitudinal Study

open access: yesFrontiers in Physiology, 2019
While the incidence of falls has been described to increase with pregnancy, the mechanism behind this is unclear. Pregnancy associated changes in lower extremity muscle strength could be a possible factor influencing injury risk.

Rare Variant of Vastus Medialis Detected in vivo by Ultrasound and Confirmed by High-resolution MRI. [PDF]

open access: yes, 2014
[Purpose] This report describes an unusual incidental finding during ultrasound investigation of the vastus medialis muscle. Volunteers underwent ultrasound scanning as part of an on-going investigation into the architecture of the vastus medialis muscle.

Bouncing Back! Counteracting Muscle Aging With Plyometric Muscle Loading

open access: yesFrontiers in Physiology, 2019
The preservation of muscle power is crucial in aging for maintaining mobility and performing daily tasks. Resistance training involving high movement velocities represents a valid strategy to slow down the rate of sarcopenia, counteracting the loss of ...
