Upper-Limb Kinematic Behavior and Performance Fatigability of Elderly Participants Performing an Isometric Task: A Quasi-Experimental Study.

ABSTRACT: Upper-limb position-sustained tasks (ULPSIT) are involved in several activities of daily living and are associated with high metabolic and ventilatory demand and fatigue. In older people, this can be critical to the performance of daily living activities, even in the absence of a disability.

Objectives

To understand the ULPSIT effects on upper-limb (UL) kinetics and performance fatigability in the elderly.

Methods

Thirty-one (31) elderly participants (72.61 ± 5.23 years) performed an ULPSIT. The UL average acceleration (AA) and performance fatigability were measured using an inertial measurement unit (IMU) and time-to-task failure (TTF).

Results

The findings showed significant changes in AA in the X- and Z-axes (p < 0.05). AA differences in women started earlier
