Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background and aims: Dizziness is a common problem among the elderly. Studies have shown that 65% of people with dizziness may have a vestibular etiologic diagnosis, possibly Benign Paroxysmal Positional Vertigo (BPPV). The diagnosis of BPPV is made by history and findings in the Dix-Hallpike test. It can be difficult to perform the Dix-Hallpike test in elderly persons due to limited range of motion when extending the neck. In this study we used a side-lying test to stimulate the posterior semicircular canal while the head and neck were fully supported on the examination table. The aims were to investigate the prevalence of dizziness or impaired balance and BPPV in a 75-year old population. Methods: A representative population sample of 675 persons completed a questionnaire about dizziness and 571 persons performed side-lying, static balance and dynamic walking tests.Results: Subjective dizziness and/or impaired balance was found in 36% especially when walking outdoors. A significant gender difference was found with a higher prevalence in women (40%) compared to men (30%) (p<0.01). BPPV was found in 11%. This was significantly more common in women compared to men (p<0.01). Elderly persons with BPPV also showed significantly impaired balance ability in static and dynamic balance tests compared to age matched persons without BPPV(p<0.01). Persons with BPPV reported significantly more subjective problems with dizziness and balance compared to persons without BPPV (p<0.001).Conclusions: Subjective and objective unsteadiness, dizziness and BPPV are common in elderly. The side-lying test is a good screening test for BPPV.

- Background and aims: Studies have shown that 65% of people with dizziness may have a vestibular etiologic diagnosis, possibly benign paroxysmal positional vertigo (BPPV). The diagnosis of BPPV is based on medical history and findings after the Dix-Hallpike test. It is sometimes difficult to perform the Dix-Hallpike test in elderly persons, due to the limited range of motion when extending the neck. In this study, we used a side-lying test to stimulate the posterior semicircular canal, while the head and neck were fully supported on the examination table. The aims of this study were to investigate the prevalence of dizziness and/or impaired balance and BPPV in a population of 75-year-olds by means of a questionnaire and clinical tests, and to compare elderly persons with and without BPPV.Methods: A representative population sample of 675 persons completed a questionnaire about dizziness and 571 persons underwent side-lying, static balance and dynamic walking tests.Results: Subjective dizziness and/or impaired balance were found in 36% of subjects, especially when walking outdoors. A significant gender difference was found, with a higher prevalence in women (40%) compared with men (30%) (p<0.01). BPPV was found in 11% and was significantly more common in women (p<0.01). Elderly individuals with BPPV also displayed significantly impaired balance in static and dynamic balance tests compared with persons without BPPV (p<0.01). Persons with BPPV reported significantly more subjective problems with dizziness and balance compared with persons without BPPV (p<0.001).Conclusions: Subjective and objective unsteadiness, dizziness and BPPV are common in the elderly.

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.

- Background: Dizziness is one of the most prevalent symptoms in old age and tends to increase with age.Aims: To report physical functioning, health-related aspects and gender differences in elderly persons with and without dizziness in a population-based sample of 75-year-olds.Methods: A cross-sectional sample of 75-year-olds from Gothenburg, Sweden (n = 675, 398 women and 277 men) was examined by means of questionnaires and functional tests. The questions concerned dizziness/imbalance, physical activity level, walking habits, falls efficacy, number of falls, subjective health or general fatigue and medication. The tests included were self-selected and maximum gait speed, stair climbing capacity, one leg stance and grip strength.Results: More women than men reported dizziness/imbalance (40 vs 30 %, p < 0.001). Persons with dizziness, compared to those without dizziness, less often regularly exercised at a moderate intensity level (summer: 62 vs 74 %, p < 0.001; winter: 41 vs 51 %, p < 0.001), less often took a daily walk (p < 0.05), had lower scores on the FES(S) (p < 0.001), more often reported general fatigue (p < 0.001), more often had fallen in the previous year (40 vs 23 %, p < 0.001) and had a higher intake of medical drugs (4.6 vs 3.3, p < 0.001). They also performed worse regarding gait speed, stair climbing and one leg stance (p < 0.001), but there was no difference in grip strength.Conclusion: Older persons with dizziness are less physically active, have worse lower extremity function, are more often fallers and report lower self-rated health than persons without dizziness.
