Detailed Description

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. A minimum of 30 eligible patients will be included. Each participant will complete both the intervention and sham conditions in a randomized sequence.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Voluntary Jaw Clenching
Participants will perform maximal voluntary jaw clenching with bilateral dental cotton rolls placed on the occlusal surfaces.
In this group, 1-cm-thick cotton rolls will be placed bilaterally on the occlusal surfaces, and patients will be instructed to perform maximal voluntary tooth clenching.
Sham Comparator: Sham Cotton Roll Placement Without Clenching
Participants will receive the same bilateral dental cotton roll positioning on the occlusal surfaces without performing jaw clenching.
In this group, 1-cm-thick cotton rolls will be placed bilaterally on the occlusal surfaces without any clenching instruction, and participants will be instructed to keep their jaw relaxed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Timed Up and Go (TUG) Test
Time Frame: Baseline and immediately post-intervention for both experimental and sham conditions
Functional mobility will be assessed using the Timed Up and Go (TUG) Test. Participants will be timed while rising from a chair, walking 3 meters, turning, walking back, and sitting down. Lower scores indicate better functional mobility.
Baseline and immediately post-intervention for both experimental and sham conditions
10-Meter Walk Test (10MWT)
Time Frame: Baseline and immediately post-intervention for both experimental and sham conditions
Gait speed will be assessed using the 10-Meter Walk Test. Participants will be instructed to walk a 10-meter distance at a comfortable walking speed, and time will be recorded to calculate walking velocity.
Baseline and immediately post-intervention for both experimental and sham conditions
