THE EFFECTS OF WALKING SURFACE AND VIBRATION ON THE GAIT PATTERN AND VIBRATION PERCEPTION THRESHOLD OF TYPICALLY DEVELOPING CHILDREN AND CHILDREN WITH IDIOPATHIC TOE WALKING by Hsinchen D. Fanchiang The aim of the current study is to investigate novel therapeutic/treatment methods and outcome measurement for children with Idiopathic Toe Walking (ITW). Fifteen typically developing (TD) children ...

This paper presents a method of measuring the vibration patterns on facial surfaces by using a scanning laser Doppler vibrometer (LDV). The surfaces of the face, neck, and body vibrate during phonation and, according to Titze (2001), these vibrations occur when aerodynamic energy is efficiently converted into acoustic energy at the glottis. A vocalist's vibration velocity patterns may therefore...

Optical coherence elastography employs optical coherence tomography (OCT) to measure the displacement of tissues under load and, thus, maps the resulting strain into an image, known as an elastogram. We present a new improved method to measure vibration amplitude in dynamic optical coherence elastography. The tissue vibration amplitude caused by sinusoidal loading is measured from the spread of...

Excessive vibration can be detrimental to the structural integrity of structures or can adversely affect the performance of instruments such as telescopes or antennas. One field in Structural Dynamics is the design and application of systems that reduce the amplitude and duration of vibration. There are two types of vibration suppression systems: passive and active. Passive means that the dampi...

[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 ...
