Self-speech-induced facilitation of simple reaching movements in persons with stroke.

Objective: Occupational therapists are routinely involved in upper-extremity rehabilitation in persons with stroke. Recently we have reported that self-speech can be used to facilitate simple reach in young and older adults. The purpose of this study is to examine whether self-speech-induced facilitation of simple reach can be translated in persons with stroke.

Lingual vibrotactile screening: an investigation of normal sensitivity based on multiple threshold determinations.

This report describes a standardized training and sensory screening procedure which was used to obtain 7 separate lingual vibrotactile thresholds for each of 5 normal subjects during a 30-day interval. Baseline observations of lingual sensitivity were highly consistent and occurred within a narrow range of contractor displacements. The authors conclude that the screening method provides a quick and reliable clinical tool for general diagnostic use and discuss directions for continued research applications.

A computerized place-manner distinctive feature program for articulation analyses.

This paper emphasizes the availability of easy-to-use computers and illustrates some advantages that might be derived from application of computers as clinical tools in our profession. A program designed to perform a series of segmental and componential analyses of misarticulations is described in illustrate a clinical application. Case study data based on 10 computer analyses are summarized and tabulated.

Spatial summation effects on lingual vibrotactile thresholds.

Ascending lingual vibrotactile thresholds at 250 Hz were obtained for four groups of normal-speaking adult subjects. Contactor areas were varied for each respective group. Threshold values in microns plotted as a function of the area of vibratory displacement indicated a spatial summation function for the larger contactors (greater than .

Temporal summation effects on lingual vibrotactile thresholds.

Ascending lingual vibrotactile thresholds at 250 Hz were obtained for four groups of normal-speaking adult subjects. Stimulus durations were varied for each respective group. Threshold values plotted as a function of stimulus duration indicated a temporal summation function occurring up to 200 msec.
