[Purpose] The purpose of this study was to investigate the effect of local vibration stimuli on body balance (trace area, trace length, and velocity) in healthy adults during double-leg standing. [Subjects and Methods] Thirty-nine subjects (10 male, 29 female) participated in this study. They were asked to keep their balance while holding four positions: standing with their eyes open, with and ...

This study proposes a new method to augment the realism of avatar by using tactile vibration and facial expression. Currently, interactive game still lack of interactivity and immersiveness. In this paper, we create an avatar with some intelligence and emotional features in order to support the realism of avatar. Our approach based on mapping the 2D valence emotion diagram to particular magnitu...

OBJECTIVES To investigate the acute response of finger circulation to vibration with different combinations of magnitude and duration but with the same "energy equivalent" acceleration magnitude according to current standards for hand transmitted vibration. METHODS Finger skin temperature (FST) and finger blood flow (FBF) were measured in the middle fingers of both hands of 10 healthy men who...

Touch of the hand with a stationary surface at nonmechanically supportive force levels (<1 N) greatly attenuates postural sway during quiet stance. We predicted such haptic contact would also suppress the postural destabilization caused by vibrating the right peroneus brevis and longus muscles of subjects standing heel-to-toe with eyes closed. In experiment 1, ten subjects were tested under fou...

The objective of this study was to describe acceptability of vulvar vibration therapy (VVT), a novel treatment approach to vulvodynia. We included women with vulvodynia who attended the Pelvic Pain Clinic and had used VVT for at least two weeks. Participants completed a three-page, 65-item, questionnaire assessing demographics, VVT usage and responses to Likert statements regarding accessibilit...

OBJECTIVES To investigate the occurrence of disorders associated with the hand arm vibration syndrome in a large population of stone workers in Italy. The dose-response relation for vibration induced white finger (VWF) was also studied. METHODS The study population consisted of 570 quarry drillers and stonecarvers exposed to vibration and 258 control stone workers who performed only manual ac...

The present series of experiments used factorial designs to evaluate which acoustic features are primarily responsible for the voicing distinction in the syllables Izil and Isi/. Increases in frication duration tend to make the syllable more voiceless only if vocal cord vibration is absent or at a very low level during the frication period. Increasing the period between the onset of frication a...

BACKGROUND Circulation plays an essential role in tissue healing. Moist heat and warm water immersion have been shown to increase skin circulation; however, these heating modalities can cause burns. Recent research has shown that passive vibration can also increase circulation but without the risk of burns. MATERIAL/METHODS The aim of this study is to compare the effects of short-duration vib...

Background Below-threshold vibration together with low-level mechanical noise (stochastic resonance) is known to have positive effects on plantar foot sensitivity and balance control [1]. However, the effects of abovethreshold stimulation on both variables are still not proved. The goal of this study was to investigate the effects of whole body vibration (WBV) training, characterized by above t...
