- OBJECTIVE: : To report the effects of glucocorticoid treatment of acute vestibular neuronitis on recovery of vestibular function and length of hospital stay. STUDY DESIGN: : Prospective, consecutive case series compared with historic controls. SETTING: : Secondary referral academic hospital. PATIENTS: : Patients with acute vestibular neuronitis. One group treated with glucocorticoids within 3 days after symptom onset (n = 33) and 2 historic untreated control groups (n = 41 and n = 67). INTERVENTIONS: : Oral prednisolone 50 mg/d for 5 days with tapering of doses for the next 5 days, alternatively with intravenous betamethasone 8 mg on the first 1 to 2 days if nauseated. MAIN OUTCOME MEASURES: : Extent of unilateral vestibular paresis (%) in the caloric test at presentation and at 12 months of follow-up. Length of hospital stay (days). RESULTS: : The initial vestibular paresis value did not differ between the treatment group and the control group. At follow-up, the treatment group showed a lower value (22.8% versus 47.2%, p = 0.0003) and greater improvement (53.4% versus 35.6%, p = 0.002). At follow-up, 70% of the treatment group had a normal caloric test result compared to only 34% of the control group. The mean hospital stay of the treatment group was significantly shorter than that of the control group (1.8 versus 3.0 d, p = 0.001). CONCLUSION: : Glucocorticoids administered within 3 days after onset of vestibular neuronitis improves long-time recovery of vestibular function and reduces length of hospital stay

Dizziness, balance and rehabilitation in vestibular disorders
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Dizziness and balance problems are common symptoms at all ages. The aims were; to evaluate rehabilitation, static, dynamic balance and recovery in acute unilateral vestibular loss (AUVL), to evaluate the treatment of benign paroxysmal positional vertigo (BPPV) with assessment of static and dynamic balance and to evaluate the prevalence of dizziness and BPPV in a population of 75-year-olds. Study 1: Twenty-seven patients (51years) with AUVL were included and the recovery was followed regarding vestibular function, dizziness, and sick-leave. The recovery was rapid, with disappearance of spontaneous nystagmus and rapid return to work. Study II: Forty two patents (51 years) with AUVL were included and compared with a reference group. Static and dynamic balance were assessed after six months. Significant instability was found both in static and dynamic balance compared to a reference group. Study III: Seventeen patients (52 years) with severe BPPV (> 3 months) were treated with Semonts´s manouver and/or Brandt-Daroff exercises. The recovery was evaluated by Dix-Hallpike test, subjective dizziness, unsteadiness and balance tests, after 1, 6 and 12 months. Semont´s maneouver resolved dizziness but the long term follow up showed impaired balance. Study IV: A large cohort (675) of elderly was assessed regarding dizziness and BPPV. Side lying test and balance tests were applied. A high prevalence of dizziness (36%) and BPPV (11%) was found. Conclusions: Patients with AUVL and BPPV have despite good symptomatic relief, still impaired static and dynamic balance at long term follow up. BPPV in elderly is common and should be examined since it can be treated.

'PREHAB': Vestibular prehabilitation to ameliorate the effect of a sudden vestibular loss.

- A sudden unilateral loss or impairment of vestibular function causes vertigo, dizziness and impaired postural function. In most occasions, everyday activities supported or not by vestibular rehabilitation programs will promote compensation and the symptoms subside. As the compensatory process requires sensory input, matching performed motor activity, both motor learning of exercises and matching to sensory input are required. If there is a simultaneous cerebellar lesion found during surgery of the posterior cranial fossa, there may be a risk of a combined vestibulo-cerebellar lesion, with reduced compensatory abilities and with prolonged or sometimes permanent disability. On the other hand, a slow gradual loss of unilateral function occurring as the subject continues well everyday activities may go without any prominent symptoms. We therefore implemented a pre treatment plan before planned vestibular lesions (prehab). This was first done in subject undergoing gentamicin treatment for Meniere's disease (MD). Subjects perform vestibular exercises for 14 days before the first gentamicin installation and then continue doing so until free of symptoms. Most subjects would only experience slight dizziness while losing vestibular function. We then expanded the approach to patients with brainstem tumours requiring surgery but with remaining vestibular function to ease postoperative symptoms and reduce risk of combined cerebello-vestibular lesions. This patient group was given gentamicin installations trans-tympanically before tumour sugary and then underwent prehab. In all cases there was a caloric loss, loss of VOR evident in the head impulse tests, impaired subjective vertical and horizontal, and reduced caloric function induced by the pre-surgery gentamicin treatment. The prehab eliminated spontaneous and positional nystagmus, subjective symptoms, and postural function up before surgery and allowed for rapid postoperative recovery.The concept of 'pre-lesion rehabilitation' where training is introduced before a planned lesion and if possible paralleled with a gradual function loss expands the potential of rehabilitation. Here it was used for vestibular lesions but it is possible that similar approaches may be developed for other situations, which include foreseeable loss of function.
