The effects of age on stabilization of the mediolateral trajectory of the swing foot

V Krishnan, NJ Rosenblatt, ML Latash, MD Grabiner - Gait & posture, 2013 - Elsevier
To ensure stability during gait, mediolateral placement of the swinging foot must be actively
regulated. Logically this occurs through end-point control of the swing limb trajectory, the …

A distal external focus of attention facilitates compensatory coordination of body parts

H Singh, HT Shih, E Kal, T Bennett… - Journal of Sports …, 2022 - Taylor & Francis
Many studies have shown that focusing on an intended movement effect that is farther away
from the body (distal external focus) results in performance benefits relative to focusing on …

Synergic control of movement: from single muscles to the whole body

ML Latash - Progress in motor control, 2024 - Elsevier
