Effects of Jaw Clenching on Gait and Mobility in Stroke

Immediate Effects of Jaw Clenching on Gait and Functional Mobility in Patients With Chronic Stroke

The aim of this study is to investigate the immediate effects of jaw clenching on gait and functional mobility in patients with chronic stroke.

This randomized sham-controlled crossover study aims to investigate the immediate effects of jaw clenching on gait and functional mobility in patients with chronic stroke.
