Effects of Strength on Selected Psychomotor Performances of Healthy and Frail Elderly Females

PDF Version Also Available for Download.

Description

The purpose of this study was to compare muscle strength and psychomotor performance measures in healthy (n = 18) and frail (n = 21) groups of elderly women utilizing movements requiring various amounts of strength and ballistic action. Subjects were community-dwelling females ranging in age from 66-92 years. Evaluations of functional assessment of motor skills and grip strength occurred. Psychomotor performance was measured through production of aiming movements on a Digitizing Tablet. RT, MT, and movement kinematics (e.g., peak velocity, deceleration, movement adjustments) were evaluated. Differences between groups were apparent in quantity and quality of movement. Healthy subjects were stronger ... continued below

Subjects were community-dwelling females ranging in age from 66-92 years. Evaluations of functional assessment of motor skills and grip strength occurred. Psychomotor performance was measured through production of aiming movements on a Digitizing Tablet. RT, MT, and movement kinematics (e.g., peak velocity, deceleration, movement adjustments) were evaluated. Differences between groups were apparent in quantity and quality of movement. Healthy subjects were stronger and faster than frail subjects, producing smoother movements with fewer adjustments. Strength appears to differentially affect healthy and frail samples and merits further exploration.
