Brief Summary

This study will compare the effect of three different physical therapy techniques on stress level on patients with bruxism by assessment of morning salivary biomarkers.

Conditions

Bruxism; Stress (Psychology)

Keywords

Bruxism; Electromyography; Biofeedback; Salivary cortisol level; progressive muscle relaxation

Outcome Measures

Primary Outcomes (1)

• Morning salivary cortisol level

  morning salivary cortisol reflect the stress level before and after the intervention on the 3 groups

  1 month

Study Arms (3)

group A

EXPERIMENTAL

15 Patients

Other: The Rocabado Program

B

EXPERIMENTAL

15 Patients

Other: Jacobson Progressive Muscle Relaxation Technique

C

EXPERIMENTAL

15 patients

Other: Surface electromyography biofeedback

Interventions

The Rocabado Program OTHER

The Rocabado program include learning a new postural position, restoring original muscle length and stiffness, normal joint mobility, and body balance.

group A

Jacobson Progressive Muscle Relaxation Technique OTHER

Jacobson developed the method of progressive muscle relaxation progressive muscle relaxation method as a supportive therapy for the treatment of neurological disorders.

B

Surface electromyography biofeedback OTHER

A non invasive process by surface electrodes that using visual and auditory cues via electronic monitoring of a normally masticatory function to train bruxers to acquire voluntary control of the hyperactivity

Model Details: Forty five male and female patients with mild and moderate bruxism participated in this study; they were divided into three equal groups the mean values ± SD of patients age of groups A, B and C were 25.6 ± 3.33, 25.67 ± 3.89 and 24.93 ± 3.22 years respectively, There was no statistical significant difference between the three groups in the mean values of age (p=0.818)., group A received 12 sessions of Rocabado program, group B received 12 sessions of Jacobson progressive muscle relaxation and group C received 12 sessions of electromyography biofeedback. Data obtained from three groups pre and post treatment regarding the morning cortisol level to measure the level of the stress.
