Rehabilitation Of Balance Function In Patients With Persistent Postural Perceptual Dizziness: A longitudinal Study

this study will be conducted to show the long term effect of combined vestibular rehabilitation incorporating optokinetic stimulation and virtual reality exercises on persistent postural perceptual dizziness patients.

Aim:1.Evaluate the balance control function in patients with persistent postural perceptual dizziness using computerized dynamic posturography.

2.To study effect of rehabilitation using optokinetic stimulation and virtual reality on persistent postural perceptual dizziness patients.

3.To follow up patients after the vestibular rehabilitation therapy to study the persistence of improvement" if any" in patients with persistent postural perceptual dizziness .

Type of the study : prospective cohort and longitudinal study. Sources of data : Audio-vestibular medicine unit , Sohag University Hospital. Study group : consists of 36 patients age ranged from 18-65 years suffering from symptoms of persistent postural perceptual vertigo.

All subjects will be submitted to:

A- Detailed medical history, full history of dizziness. B-Acoustic impedance test. C-Basic audiological evaluation. D- Vestibular assessment.

Inclusion Criteria:

• Age: from 18 years to 65 years old.
• Gender: males and females.
• Can withstand and willing to undergo repeated vestibular rehabilitation therapy .*No history of any disease required to give treatment that could affect results.

Exclusion Criteria:

• Neurological disorders, paresis, paralysis, motor disorder, ataxia, brain mass, multiple sclerosis and stroke with grade 4 muscle power or below.
• Otological disorders e.g. middle ear pathology (chronic suppurative otitis media, Tumor).
• Psychiatric disorders e.g. Schizophrenia and endogenous depression.
• Severely ill patients who would not tolerate vestibular rehabilitation therapy .
