Inspiration-induced vasoconstrictive responses in dominant versus non-dominant hands.

Single rapid and deep inspirations (inspiratory gasps, IG) result in arteriolar vasoconstriction with concomitant transient decreases in skin blood flow that are most prominent in fingers and toes. Vascular responses (inspiratory gasp responses, IGR) are determined as the maximum percentage reduction in blood flow and have been used to assess sympathetic neurovascular function in several condit...

Effect of Dominant Versus Non-dominant Vision in Postural Control

OBJECTIVE To assess the effect of dominant and non-dominant vision in controlling posture in quiet stance. METHOD Twenty-five healthy elderly subjects aged over 60 years old and twenty-five young subjects aged under 30 years old were assessed by computerized dynamic posturography. Postural stability was measured in two conditions; dominant eye open and non-dominant eye open. We used the senso...

Reliability of Strength Measures for the Dominant and Non-dominant Hands

The reliability of a measure refers to its degree of consistency or stability. Test-retest reliability involves administering the same test twice (Voyer, 1998). A perfectly reliable test would give the same results on both occasions. Intraclass correlation coefficients indicate the degree of reliability for continuous measures (Portney & Watkins, 2000). The reliability of grip strength measurem...

Comparing Dominant and Non-Dominant Hand Performance with Force Changes In a Two-Hand Equilibrium Task: A Challenge to Dominant Hand Theories

Objective: Although most studies believe that the dominant hand performs better than the non-dominant hand in performing various tasks, there is still the challenge among researchers as to why the non-dominant hand performs better than the dominant hand in certain situations and tasks. The aim of this study was to compare dominant and non-dominant hand performance with force changes in a two-ha...
