These results indicate that: (1) Patients with high tetraplegia use many neck muscles in addition to the sternocleidomastoids to breathe; (2) The synchronous contraction of these muscles acts to pull the sternum cranially, expands the upper rib cage, and causes paradoxical inward displacement of...

The mind-muscle connection refers to the conscious effort to focus one’s attention on the contraction of a specific muscle or muscle group during exercise. This practice involves mentally engaging with the working muscle, aiming to isolate and enhance its activation without relying solely on the ...
Next, assuming that a muscle consists of a contractile element and an elastic element, the energy consumed by the muscles is formulated as a function of the muscular forces and the contraction velocities of the muscles. Then, the muscular force sharing is predicted by solving an optimization ...
Muscle contraction Antagonist muscles: muscles that stretch in the opposite direction. Muscle relaxation Flexion / flexion (bow) of the 1 cervical spine: normal range of motion: 0 - 60 degrees Active muscles: sternocleidomastoid muscle (both sides), Longus and longus longus Anterior cervical muscle...
Progression through active assisted and active ROM follows, and when appropriate, some resistance to motion may be introduced for strengthening. Passive Range of Motion Passive ROM is motion of a joint that is performed without muscle contraction within the available ROM, using an external force to...
If cocontraction of antagonistic muscles occur, the joint force could be enhanced. Detailed gate analysis should be performed for three-dimensional model. In normal walking, the example of reaction forces on floor is shown in Fig. 2.14 (Miyazaki, 2002). It is noticed in vertical component of ...
There are several methods to measure cardiomyocyte and muscle contraction, but these require customized hardware, expensive apparatus, and advanced informatics or can only be used in single experimental models. Consequently, data and techniques have been difficult to reproduce across models and ...
(a) The work done by leg muscles in each stride is the muscle force \(\times \) the muscle contraction distance. Show that this scales at \(L^{3}\).(b) The kinetic energy of that limb is \(I(\mathrm{d}\theta /\mathrm{d}t)^{2}/2\), where I is the moment of inertia ...
