The Epley Maneuver Versus Cawthorne-Cooksey Exercises in the Treatment of Benign Paroxysmal Positional Vertigo (BPPV)

Not Applicable

Completed

• Conditions: Benign Paroxysmal Positional Vertigo
• Interventions: Procedure: Epley maneuver

• Registration Number: NCT04715282
• Lead Sponsor: Istinye University

Brief Summary

Observation of the effects of Cawthorne-Cooksey exercises applied after the Epley maneuver on balance, vertigo symptoms, and quality of life in BPPV patients.

Detailed Description

Study Objective:

To observe the efficacy of Cawthorne-Cooksey exercises applied after the Epley maneuver on balance, vertigo symptoms, and quality of life in patients with posterior canal BPPV.

Study Design:

Single-blind randomized controlled study

Sample Size:

Thirty-six patients were recruited in the study and were randomized equally into Epley maneuver (EpleyM) and Epley maneuver and exercise (EpleyM\&Exe) groups.

Study Method:

All patients were treated with the Epley maneuver, while CawthorneCooksey exercises were given to the EpleyM\&Exe group as home exercises for 6 weeks. Static and dynamic balance, vertigo and associated symptoms, and quality of life were assessed with the Nintendo Wii Balance Board, Berg Balance Test, Vertigo Symptom Scale, and Dizziness Handicap Inventory, respectively. The assessments were repeated at the 1st, 3rd, and 6th weeks.

Arm && Interventions

Group	Intervention	Description
Epley maneuver	Epley maneuver	The Epley maneuver was performed for all patients (both EpleyM and EpleyM\&Exe groups) included in this study until nystagmus had disappeared in each position. If nystagmus/vertigo was not seen, the Epley maneuver was not performed for patients at the 1st, 3rd, and 6th week assessments.
Cawthorne-Cooksey exercises combined with the Epley maneuver	Epley maneuver	Additional Cawthorne-Cooksey exercises were prescribed to the EpleyM\&Exe group. The physiotherapist explained and demonstrated the exercises to each patient and the patients practiced the exercises until they performed them correctly. Then the exercises were prescribed twice a day and repeated 10 times for 6 weeks as a home exercise program.

Primary Outcome Measures

Name	Time	Method
Nintendo Wii Balance Board (WBB)	one hour	COP displacement on double leg with eyes open/closed (%): Lower scores (approaching 50%) indicate better static balance.; Frontal plane stability on dominant leg with eyes open/closed (%): The total score ranges between 0 and 100%. Higher scores indicate better static balance.
Berg Balance Test (BBT)	one hour	The minimum score of the BBT is 0 and the total maximum score of the BBT is 56. Higher scores indicate better dynamic balance.

Secondary Outcome Measures

Name	Time	Method
Vertigo Symptom Scale (VSS)	one hour	The total score ranges between 0 and 60 points, with higher scores indicating lower vertigo associated symptoms.
Dizziness Handicap Inventory (DHI)	one hour	The total score ranges between 0 and 100 points, with higher scores indicating lower quality of life.
