Performing Isometric Force Control in Combination with a Cognitive Task: A Multidimensional Assessment.

Introduction: We used a multidimensional approach to study isometric force control in single and dual-task conditions.

Methods: Multiple measures of performance, efficiency, variability, and structural interference were calculated at low and higher force levels under single (force maintenance) and dual-task (force maintenance and reaction time) conditions.

Results: Reaction time and signal-to-noise ratio were larger in the dual-task conditions.

Effects of a light touch on fixed or mobile supports on gait parameters in visually restricted young adults.

We investigated the effects of lightly touching fixed and mobile supports on gait parameters and center of mass oscillations in visually restricted young adults. Fourteen healthy male and female adults of mean=23.6 years (SD=1.
