Alterations in muscular control when performing unfamiliar elbow flexion and extension movements.

ABSTRACT:

Purpose

This work analyzes how the Central Nervous System (CNS) adapts its control strategies-muscle synergies and muscular coactivation-during unfamiliar elbow flexion/extension tasks at different velocities.

Methods

Twenty healthy participants (10 male; 10 female; age 31 ± 10,2 years) were recruited. Muscular activation of the biceps brachii, brachioradialis, and triceps brachii was recorded using surface electromyography. Elbow movements were tracked using a motion-capture system and an upper body biomechanical model. To represent an unfamiliar task, participants performed the movement in the transverse plane, while the familiar task was performed in the sagittal plane to allow for comparison. Movements were executed at different angular velocities to assess their effect.
