School seroprevalence showed a wider prevalence range than microscopy for both P. falciparum (0 50% versus 0 12.7%) and P. vivax (0 53.7% versus 0 4.5%), respectively.
Although the wide prevalence range suggests a heterogeneous definition of disorders included in these studies, it becomes apparent that musculoskeletal disorders represent a major problem among instrumental musicians.
The wide prevalence range is partially a reflection of the influence of age and gender.
For Parkinsonism, the wide prevalence range observed both in population and hospital-based studies might also be a consequence of differences in methodologies for case ascertainment, diagnostic criteria, or age distributions of the study populations.
Factors other than methodological quality and TBI severity are likely to explain the observed wide prevalence ranges.
Notwithstanding the wide prevalence ranges and variability of spinal pain definition, it appears that TSP may be a significant a problem in adulthood.
Myofascial pain syndrome (MPS) is the most frequent cause of chronic musculoskeletal pain [ 1– 6], with estimates of world-wide prevalence ranging from 0.5% to 5.0% [ 6– 8].
