[Non-specific exercise therapy for benign paroxysmal postural vertigo].

We treated 1145 patients diagnosed as having benign paroxysmal postural vertigo at the Toho University Medical Center Sakura Hospital from August 2007 to July 2009 by the exercise therapy developed by us. The most advantageous characteristic of our method is that patients can perform the exercises themselves at their own pace in their homes, even if the affected side cannot be identified and/or the patients have any orthopedic cervical and/or spinal problems. In 80.7% and 91.7% of the patients in our case series, the vertigo was no longer present at one and three months, respectively. In addition, the vertigo disappeared within two weeks in the patients who were examined within one week of the start of the symptom. The longer the period between the onset of vertigo and the hospital visit, the longer the period needed for control of the symptom.

[Examination of dynamic body balance using the body tracking test in cases of vestibular neuronitis].

Body Tracking Test (BTT) is a testing method of the dynamic body balance function wherein movement of the center of gravity in accordance with a moving visual target stimulus is examined to evaluate the tracking function of the body. The objects were the patients who were diagnosed as having vestibular neuronitis at the Department of Otolaryngology in Toho University medical center Sakura hospital, and were undergoing hospital treatment. Lateral BTT was performed in 31 subjects, and antero-posterior (A-P) BTT in 45 subjects. Although gaze nystagmus was noted, inspection was enforced when a standing position posture was possible. In lateral BTT, the average (cm/second) horizontal direction body sway speed was compared, however, no clear lateral difference was noted. In the antero-posterior (A-P) BTT, it inquired using the direction body sway average center displacement (cm) of X. Deviation was seen by the affected side in stabilometry. Deviation was seen by the unaffected side in the antero-posterior (A-P) BTT. This phenomenon differs from the deviation pattern until now and is considered to involve participation of the higher centers.
