Background: The upper extremity spasticity following stroke limits individuals' activities of daily living. Focal muscle vibration (FMV) is a device producing vibration signals affecting the central nervous system. Objective: This systematic review was conducted to investigate the effects of FMV on individuals with stroke, and to identify the effective training protocol in reducing upper ...

Theory: Reciproing Engine Vibration Analysis

Theory: Reciproing Engine Vibration Analysis

Normal Vibration Signature . Each combustion pulse acts much like a hammer blow, hitting the engine block with a pulse of energy. The vibration spectrum of such a pulse is a series of vibration spectral lines. These spectral lines will be at integer multiples of the firing rate of each piston. In a four stroke engine the piston fires every other revolution, therefore the fundamental spectral ...

Stroke is a common neurological medical condition. Every year 62,000 Canadians experience a stroke or transient ischemic attack (Hebert et al., 2016) and 405,000 Canadians live with the effects of stroke, with that number projected to increase to between 654,000 and 726,000 by 2038 (Krueger et al., 2015). Stroke impacts an individual's ability to participate in former activities and life ...

How to choose and use vibratory feeders and conveyors

During a vibrating stroke the tray surface travels between its lowest point "A" to its highest limit "C". On the upward stroke, the particle is in contact with the tray from "A" to "B". At that point the velocity of the particle become greater than the tray and the particle leaves the surface on a feed flight trajectory from "B" to "D". The particle lands forward on the ...

How To Measure Noise Vibration In Rotating Machines

 · Every rotating part in a machine generates vibration, and hence noise, as a result of small imperfections in the balance or smoothness of the components of the machine. In addition, there are socalled "bladepassing" phenomena associated with blades of fans and pumps. In every case, we can relate the frequency of the vibration to the speed of the rotating machine. For example, a fan with ...
