Sporadic inclusion body myositis (S-IBM) is a progressive, acquired disease of unknown etiology. Prior studies have suggested neurogenic involvement based on electrophysiologic data, although the biopsy is compatible with a myopathic process. Quantitative electrophysiologic studies were performed in

โฆ Synopsis
A 10-year retrospective review was conducted to ascertain the prevalence of inclusion body myositis (IBM) in Western Australia. Seventeen patients with sporadic IBM aged 45-90 years were identified and the prevalence of IBM was calculated to be 9.3 ร 10 -6 . The prevalence was higher in men (10.9 ร 10 -6 ) than in women (7.7 ร 10 -6 ). The mean age of onset of IBM was 56.6 years, and the mean delay between onset of symptoms and diagnosis was 4.4 years. The age-adjusted prevalence over the age of 50 years was 35.3 ร 10 -6 . The results suggest a higher prevalence of IBM than has previously been reported.
