What is an anterior perturbation?
Anterior perturbations (mean C7 acceleration 251.7 mg) evoked activity within the dorsal muscles (SOL, HS, PS) with a similar latency to voluntary responses to shoulder tapping.
What are perturbations in physics?
perturbation – (physics) a secondary influence on a system that causes it to deviate slightly. natural philosophy, physics – the science of matter and energy and their interactions; “his favorite subject was physics”
What is a balance perturbation?
Perturbation-based balance training (also referred to as reactive balance training or perturbation training) utilizes a task-specific approach to balance training, applying repeated exposure to unpredictable mechanical perturbations that mimic balance disturbances experienced in daily life.
What is perturbation theory?
Definition of perturbation theory : any of various methods of calculating the approximate value of a complex function (such as the energy of an electron in quantum mechanics) by first assuming that the dominant influence is the only factor and then making small corrections for additional factors.
What is a functional balance?
Functional balance is the integration of static and dynamic balance training to maintain or improve Activities of Daily Living (ADL) and Quality of Life (QoL). Static balance is the ability to maintain a position.
What is computerized dynamic Posturography?
Computerized dynamic posturography with the EquiTest is an objective technique for measuring postural strategies under challenging static and dynamic conditions. As part of a diagnostic assessment, the early detection of postural deficits is important so that appropriate and targeted interventions can be prescribed.
What is the use of perturbation?
One of the most important applications of perturbation theory is to calculate the probability of a transition between states of a continuous spectrum under the action of a constant (time-independent) perturbation.
Why do we use perturbation?
Perturbation is used to find the roots of an algebraic equation that differs slightly from one for which the roots are known. Other examples occur in differential equations.
