Prevalence of back pain in a group of elite athletes exposed to repetitive overhead activity.

PLoS One 2019 24;14(1):e0210429. Epub 2019 Jan 24.

Department of Sports Medicine and Sports Nutrition, Ruhr-University Bochum, Bochum, Germany.

Background: The prevalence of back pain in athletes has been investigated in several studies, but there are still under- or uninvestigated sports discipline like sports exposed to repetitive overhead activity. Elite athletes spend much time in training and competition and, because of the nature of their disciplines, subject their bodies to a great deal of mechanical strain, which puts a high level of stress on their musculoskeletal systems. From this it is hypothesized that elite athletes who engage in repetitive overhead motions experience a higher strain on their spine and thus possibly a higher prevalence of back pain compared with an active control group.

Optical Rehabilitation of a Patient with Keratoconus and Nystagmus.

Med Hypothesis Discov Innov Ophthalmol 2018 ;7(4):183-189

Kentucky College of Optometry, University of Pikeville, Pikeville, KY, USA.

Keratoconus is a progressive corneal disease characterized by bilateral yet usually asymmetric thinning of the cornea with an onset typically in teenage years. While it often presents as an isolated condition, keratoconus may also be associated with many systemic and/or ocular diseases, such as connective tissue and chromosomal disorders. Its association with nystagmus has been described in Leber's congenital amaurosis, where patients also exhibit abnormal pupillary responses, early-onset retinal dystrophy, mental developmental delays, and eventual blindness.
