The influence of contraction duration in muscle energy technique applied to the atlanto-axial joint [PDF]

, 2004
Background: Muscle Energy Technique (MET) has been advocated for the treatment of restricted range of motion in the upper neck. There is little evidence, however, to support the effectiveness of MET to increase motion in the cervical spine, or determine ...

An electrooptical muscle contraction sensor [PDF]

, 2010
An electrooptical sensor for the detection of muscle contraction is described. Infrared light is injected into the muscle, the backscattering is observed, and the contraction is detected by measuring the change, that occurs during muscle contraction ...

Preliminary study of muscle contraction assessment by NIR spectroscopy [PDF]

, 1998
NIR spectroscopy allows monitoring of muscle oxygenation and perfusion during contraction. The knowledge of modifications of blood characteristics in body tissues has relevant clinical interest. A compact and reliable device, which makes use of two laser

Insights From Computational Modeling Into the Contribution of Mechano-Calcium Feedback on the Cardiac End-Systolic Force-Length Relationship

Frontiers in Physiology, 2020
In experimental studies on cardiac tissue, the end-systolic force-length relation (ESFLR) has been shown to depend on the mode of contraction: isometric or isotonic.

Effect of hip adduction/abduction contraction on pelvic floor in young healthy women

Journal of Physical Fitness and Sports Medicine, 2022
Pelvic floor muscle training has been reported to be effective in preventing and improving urinary incontinence. Patients must learn to perform pelvic floor muscle contractions without pushing down the pelvic floor by contracting other muscle groups ...

Influence of Joint Angle on Residual Force Enhancement in Human Plantar Flexors

Frontiers in Physiology, 2017
Compared to pure isometric contractions, isometric muscle force at a given length is larger when the eccentric contraction is conducted before the isometric contraction.

Extrapolation of time series of EMG power spectrum parameters in isometric endurance tests of trunk extensor muscles [PDF]

, 1998
The aim of the present study was to test the viability of using short isometric contractions of trunk extensor muscles to perform an assessment of their endurance capacity. To this aim two types of analysis were performed.

Regional Differences in Biceps Femoris Long Head Stiffness during Isometric Knee Flexion

Journal of Functional Morphology and Kinesiology, 2021
This study sought to investigate whether the stiffness of the biceps femoris long head differs between proximal and distal regions during isometric knee flexion at different contraction intensities and muscle lengths. Twelve healthy individuals performed
