The proposed impulse model incorporates the duty ratio and input frequency of the triangular waveform of counter mass relative displacement as the system input and outputs the estimated step size and the behavior of the stepping motion.
In fact, the calculated randomness factor, which is an indicator of the tight coupling between ATP hydrolysis and the stepping motion, showed a decrease in tight coupling, suggesting futile steps.
This high-speed AFM (HS-AFM) has been used to visualize molecular movements such as the stepping motion of myosin V along actin filaments (Kodera et al., 2010), rotary catalysis of F1 ATPase without a rotor (Uchihashi et al., 2011), and light-induced conformational changes in bacteriorhodopsin (Shibata et al., 2010).
This means that the non-motor protein subunits are not provided with the energy to make a stepping motion; this raises questions about how the Kar3 motor protein moves along the microtubule, and whether this affects the roles the motor performs.
A trainer then helped the patient to perform a stepping motion by extending his leg, placing his foot on the treadmill, retracting it, and so on.Over the course of a few months, all seven patients developed the rudiments of walking.
Wernig's experiment was inspired by the observation that when newborn babies are held upright, their toes touching the ground, they spontaneously move their feet in a stepping motion.
Stable stepping motion from mechanical excitation of a piezoelectric device is generated using the impact drive mechanism (IDM) based on various triangular waveforms exerted by the counter mass speed.
In the presence of this stimulation they can stand, move their lower limbs on command and generate a rhythmic stepping motion in a gravity neutral position.
Recently, Yildiz et al (2008) showed that external force can achieve a stepping motion with a neck linker-replaced mutant, interpreting this to mean internal strain acts on the head directly.
To examine the stepping performance during voluntary and waist-pull perturbation-induced step initiation in people with chronic stroke.
