Arnold Kegel
Arnold Henry Kegel was an American gynecologist who invented the Kegel perineometer and Kegel exercises as non-surgical treatment of urinary incontinence from perineal muscle weakness and/or laxity. Today pelvic floor exercises are widely held as first-line treatment for urinary stress incontinence and any type of female incontinence and female genital prolapse, with evidence supporting its use from systematic reviews of randomized trials in the Cochrane Library amongst others. Kegel first published his ideas in 1948. He was Assistant Professor of Gynecology at the Keck School of Medicine of USC.
