Unions have split over the merits of a drug company-sponsored television campaign on incontinence. The Chartered Society of Physiotherapy condemned the advertisements, saying they could lead the public to demand drugs they did not need. It said exercises to strengthen pelvic floor muscles should be promoted as 'the first-line treatment for incontinence'. But the Royal College of Nursing argued that the campaign was a 'highly effective' method of raising public awareness of a 'taboo issue'.
