Functional connectivity of proximal and distal lower limb muscles and impact on gait variability in stroke.

ABSTRACT:

Background

Higher gait variability after stroke increases risk of falls and compromises safe community ambulation. Corticomotor connectivity plays an important role in walking after stroke, however, its relation to gait variability remains unknown.

Research question

Do corticomotor characteristics of the proximal and distal lower limb muscles predict gait variability in individuals with chronic stroke?

Methods

Retrospective analysis of data from 30 individuals with chronic stroke was conducted. Corticomotor characteristics were measured in the paretic and non-paretic tibialis anterior (TA, distal muscle) and rectus femoris (RF, proximal muscle) using transcranial magnetic stimulation. We calculated corticomotor excitability ratio of paretic TA and RF (CME_TA/RF
