The occupational uses with vibratory tools or vehicles provoked health disorders of users. We reviewed narratively our articles of 35 yr studies and their related literatures, and considered the pathophysiology of the hand-arm vibration disorders. Concerning the risk factors of health impairments in workers with vibratory tools, there are two conflicting schools of the researchers: The peripher...

To compare effects of vibratory and mechanical ventilation on fluid balance in the newborn lung, we measured pulmonary arterial and left atrial pressures, pleural and airway pressures, lung blood flow and lymph flow, and concentrations of protein in lymph and plasma of 19 healthy lambs, 2-4 weeks old, during a 2- to 4-hour period of spontaneous breathing, followed by 4-8 hours of mechanical ven...

This study aims to evaluate the efficiency of an orthotic device in treating proximal humerus fractures. The following research methods were used Orthosis user group compare non-orthotic terms PHFs management. Physical function daily activities and recovery assessed using DASH, SPADI, SST, Muscular Strength, CONSTANT scores, radiological assessment, as well questionnaire AND mathematically (sta...

During mating, males and females of N. viridula (Heteroptera: Pentatomidae) produce sex- and species-specific calling and courtship substrate-borne vibratory signals, grouped into songs. Recognition and localization of these signals are fundamental for successful mating. The recognition is mainly based on the temporal pattern, i.e. the amplitude modulation, while the frequency spectrum of the s...

The relationship between vibration and human motor unit spikes elicited by reflex and voluntary actions was studied by means of cross-correlograms. Using this method motor unit spikes could be classified into two categories, locked spikes with good correlation to vibratory frequency and unlocked ones with poor correlation to vibratory frequency. 1. Inter-spike intervals of the locked spikes wer...

The design of a motion control system for a powered reciprocating gait orthosis is considered. Models for the orthosis are obtained using least squares identification. The control system design is based on pole-placement techniques and a restricted Youla parametrization of the controller. Experimental results are included.

Vibratory manipulation is the use of repeated impacts, typically at high frequency and low amplitude, to manipulate objects. Although this sort of manipulation is commonly used, e.g. in parts feeding systems, there has been relatively little work on formally analyzing the mechanics. In this paper, we focus on manipulating a planar slider repeatedly tapped by a vibrating manipulator. We find tha...

introduction: functional ankle instability has described as a “feeling of giving way”. balance control deficit is one of the sensorimotor impairments observed in people with functional ankle instability that has been described to damage to the afferent receptors within the ligaments and joint capsule that affected during sprain. foot orthosis can improve balance control via enhanced sensory aff...

OBJECTIVE To examine, for polio survivors, whether walking with a carbon-fibre reinforced plastic knee-ankle-foot orthosis (carbon KAFO) is more efficient than walking with an ordinary KAFO or without an orthosis. DESIGN Consecutive sample. SETTING Post-polio clinic, University Hospital of Occupational and Environmental Health, Kitakyushu, Fukuoka, Japan. PARTICIPANTS Eleven polio survivo...
