Brief summary
The aim of the study is to investigate the effects of stimulated occlusal imbalance and jaw clenching on balance and fall risk in patients with stroke.
Detailed description
This randomized controlled study will be conducted on a minimum of 42 stroke patients who meet the inclusion and exclusion criteria. Patients included in the study will be randomly assigned to one of three groups: the ipsilateral side stimulated occlusal imbalance group, the contralateral side stimulated occlusal imbalance group, or the bilateral jaw clenching group.
Interventions
OTHERIpsilesional Side Stimulated Occlusal Imbalance
In this group, a 1 cm thick cotton roll will be placed on the ipsilesional occlusal surfaces of the patients, and they will be instructed to hold it in place without clenching.
OTHERContralesional Side Stimulated Occlusal Imbalance
In this group, a 1 cm thick cotton roll will be placed on the contralesional occlusal surfaces of the patients, and they will be instructed to hold it in place without clenching.
OTHERBilateral Cotton Roll with Jaw Clenching
In this group, a 1 cm thick cotton roll will be placed on both occlusal surfaces, and the patients will then be instructed to clench their teeth.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall Postural Stability Index Measurement | Change from baseline overall postural stability index immediately after the intervention | This index will be assessed by measuring deviations of the center of gravity in the anteroposterior and mediolateral directions. Lower scores indicate smaller deviations and better postural stability. The test will be performed on a stable platform with two trials of 30 seconds each. The average of the two trials will be automatically calculated by the TechnoBody balance system. |
| Fall Risk Assessment | Change from baseline fall risk immediately after the intervention | Fall risk will be assessed by measuring the patient's ability to maintain balance on an unstable platform. Based on their ability to maintain balance, a fall risk score will be generated, with higher scores indicating a greater risk of falling. The test will be performed with two 30-second trials. The average of the two trials will be calculated automatically by the TechnoBody balance system. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Anteroposterior Stability Index Measurement | Change from baseline anteroposterior stability index immediately after the intervention | The anteroposterior stability index will be assessed by measuring deviations of the center of gravity in the anteroposterior direction. Lower scores indicate smaller deviations and better anteroposterior postural stability. The test will be performed on a stable platform with two trials of 30 seconds each. The average of the two trials will be automatically calculated by the TechnoBody balance system. |
| Mediolateral Stability Index Measurement | Change from baseline mediolateral stability index immediately after the intervention | The mediolateral stability index will be assessed by measuring deviations of the center of gravity in the mediolateral direction. Lower scores indicate smaller deviations and better mediolateral postural stability. The test will be performed on a stable platform with two trials of 30 seconds each. The average of the two trials will be automatically calculated by the TechnoBody balance system. |
| Weight Bearing Distribution Assessment | Change from baseline weight bearing distribution immediately after the intervention | Weight-bearing distribution will be assessed by measuring the percentage of body weight borne by each limb during quiet standing. Lower asymmetry values indicate more balanced weight distribution and better postural stability. The test will be performed on a stable platform with two trials of 30 seconds each. The average of the two trials will be automatically calculated by the TechnoBody balance system. |
