About

The standard treatment of posterior semicircular canal benign paroxysmal positional vertigo is the canalith repositioning procedure or the Epley maneuver. Based on the present literature, there is controversy on the efficacy of post-maneuver postural restrictions.The aim of this study was to conduct a randomized controlled trial to compare the treatment efficacy of post-maneuver postural restriction with CRP alone in patients with posterior semicircular canal benign paroxysmal positional vertigo.

Full description

Benign paroxysmal positional vertigo is the most common cause of vertigo. Based on the present literature, there is controversy on the efficacy of post-maneuver postural restrictions.Some study designs were not randomized controlled trials. The present study offers an alternative way of postural restriction to maintain postural restriction as much as possible.

Postural restriction

Experimental group

Description:

The patients were instructed to avoid head movements, wear a soft collar during the daytime, wear a supporting pillow and sleep in the semi-upright position at a 45 degree head elevation from the horizontal plane during the nighttime for 48 hours.

Treatment:

Behavioral: Postural restriction

Normal daily activity

Active Comparator group

Description:

The patients did not follow any postural restrictions and were asked to live as normally as possible.

Treatment:

Behavioral: Normal daily activity
