Details and patient eligibility

About

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.

Full 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.

Enrollment: 60 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Having chronic stroke,
• A Mini-Mental State Examination score of 24 or higher,

• Ability to stand independently for 20 seconds or more,
• Ability to walk independently for 10 meters, using assistive devices or orthoses if necessary,
• Having opposing mandibular and maxillary second premolars or first molars

Exclusion criteria

• The presence of cancer or diabetic neuropathy,
• The presence of vestibular disorder,
• The presence of lower extremity ulceration or amputation,

60 participants in 3 patient groups

Ipsilesional Side Stimulated Occlusal Imbalance Group

Experimental group

Description:

In this group, occlusal imbalance will be induced by placing a cotton roll on the ipsilesional occlusal surfaces of the patients.

Treatment:

Other: Ipsilesional Side Stimulated Occlusal Imbalance

Contralesional Side Stimulated Occlusal Imbalance Group

Experimental group

Description:

In this group, occlusal imbalance will be induced by placing a cotton roll on the contralesional occlusal surfaces of the patients.

Treatment:

Other: Contralesional Side Stimulated Occlusal Imbalance

Bilateral Cotton Roll with Jaw Clenching Group

Experimental group

Description:

Patients in the bilateral cotton roll with jaw clenching group will clench their teeth while cotton rolls are placed on both sides of the occlusal surfaces.

Treatment:

Other: Bilateral Cotton Roll with Jaw Clenching
