Recent studies have suggested that vibration therapy may have a positive influence on motor symptoms in individuals with Parkinson's disease (PD). However, quantitative evidence of these benefits is scarce, and the concept of "whole-body" vibration in these studies is vague. The objectives of the current study were to evaluate the influence of vibration on motor symptoms and functional measures...

background : the application of ventilation systems in industries and workplaces is with the aim of improving environmental conditions for employees. the lack of appropriate ventilation system components design and control methods result in the production of sound and vibration in most components. the purpose of this study was to determine the role of the pad isolator in controlling vibration a...

Vibration training has become a popular method used in professional sports and recreation. In this study, we examined the effect of whole-body vibration training on the central nervous system and muscle excitability in a group of 28 active men. Subjects were assigned randomly to one of two experimental groups with different variables of vibrations. The chronaximetry method was used to evaluate ...

A smart home environment based on pervasive networkedsensors enables us to measure and analyze various vital signals related to personal health care. For example, the vital signals on footstep, gait pattern, and posture can be used for assessing the health state among the elderly and disabled people. In this manuscript, we use footstep vibration signals measured by network-based MEMS accelerome...

Muscle-tendon vibration has often been used to study the contribution of proprioception to kinesthesia and postural control. This technique is known to simulate the lengthening of the vibrated muscle and, in the presence of balance constraints, evoke compensatory postural responses. The objective of the present study was to clarify the consequences of this stimulation on the dynamic features of...

In order to reduce the cropping force and enhance the cropping cross-section quality, a new type of cropping machine is proposed in this paper. The basic structure and working principle of the cropping machine are introduced. Based on D'Alembert's principle, the vibration equations of the cropping machine along the Y direction, X direction and around X, Y, Z axis are built in detail and the mot...

OBJECTIVES Loss of foot sensitivity is a relevant parameter to assess and prevent in several diseases. It is crucial to determine the vibro-tactile sensitivity threshold response to acute conditions to explore innovative monitor tools and interventions to prevent and treat this challenge. The aims were: 1) to analyze the acute effects of a single whole body vibration session (4min-18Hz-4mm) on ...

Models of the vertical apparent mass of the human body are mostly restricted to a sitting posture unsupported by a backrest and ignore the variations in apparent mass associated with changes in posture and changes in the magnitude of vibration. Using findings from experimental research, this study fitted a single degree-of-freedom lumped parameter model to the measured vertical apparent mass of...

BACKGROUND Patients with stable COPD show improvements in exercise capacity and muscular function after the application of whole body vibration. We aimed to evaluate whether this modality added to conventional physiotherapy in exacerbated hospitalised COPD patients would be safe and would improve exercise capacity and quality of life. METHODS 49 hospitalised exacerbated COPD patients were ran...

OBJECTIVE To assess the effects of whole body vibration for pain, stiffness and physical functions in patients with knee osteoarthritis. DATA SOURCES We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Physiotherapy Evidence Database (PEDro) and EMBASE (up to October 2014) to identify relevant randomized controlled trials. The outcome measures were pain, stiffness and phy...
