Assessment strategies are an important component in game theoretical models of contests. Strategies can be either based on one's own abilities (self assessment) or on the relative abilities of two opponents (mutual assessment). Using statistical methodology that allows discrimination between assessment types, we examined contests in the jumping spider Phiddipus clarus. In this species, aggressi...

[Purpose] The aim of current study was to investigate the effect of external cues using vibratory stimulation on spatiotemporal gait parameters in patients with chronic stroke. [Subjects] Thirty patients, who had suffered a stroke, were selected from general hospitals in Seoul, Republic of Korea. [Methods] Each participant was subjected to six walking trials: three trials with vibratory stimula...

We investigated the effects of forearm flexor/extensor muscles vibration on corticospinal excitability by means of transcranial magnetic stimulation (TMS) in healthy subjects. Motor evoked potentials (MEPs) and ongoing baseline activity of forearm flexor and extensor muscles were analyzed during muscle activity increase produced by vibration of these muscles (Tonic Vibratory Reflex) and by anta...

Methods: Eight children with cerebral palsy wore a modified FRAFO bilaterally for six weeks. Motion analysis was used to assess the immediate effectiveness of the orthosis on improving gait and also following six weeks of gradual orthosis use. Primary outcome measures were walking speed, cadence and stride length, plus hip, knee and ankle joint ranges of motion. A paired T test was used to comp...

Introduction Several methods to decrease foot pressure applying foot orthosis wedge or gait strategies by evaluating foot pressure increased abnormally by various foot diseases are under investigation [1]. Recently, studies on foot orthosis, diabetic shoes and old people footwear have been conducted, but there have been a few studies on orthotic devices such as metatarsal pad, dome and wedge [2...

This paper describes the development and preliminary testing of a functional upper-limb orthosis for people that have limited strength in their arms. This is symptomatic of conditions such as muscular dystrophy (MD), spinal muscular atrophy (SMA), and partial spinal cord injury. The exoskeletal orthosis is wheelchair mounted, has two links and four degrees of freedom. It uses linear elastic ele...

OBJECTIVES/HYPOTHESIS The aim of the study was to present the development of a miniature laser projection endoscope and to quantify vocal fold length and vibratory amplitude of the pediatric glottis using high-speed digital imaging coupled with the laser endoscope. STUDY DESIGN For this prospective study, absolute measurement of entire vocal fold length, membranous length of the vocal fold, a...

Plants limit the range of insect substrate-borne vibratory communication by their architecture and mechanical properties that change transmitted signal time, amplitude and frequency characteristics. Stinkbugs gain higher signal-to-noise ratio and increase communication distance by emitting narrowband low frequency vibratory signals that are tuned with transmission properties of plants. The obje...

The physiology of the vibratory mechanism in alaryngeal tracheoesophageal speech depends on several factors. The structure and resulting function of the neoglottis (or neopharynx) varies from patient to patient depending on the individual details of the surgical procedure performed, as well as the patient's anatomy. In general, the vibratory segment is a blending of the pharyngeal constrictor m...
