When it comes to parenting, back injury is an occupational hazard. New mothers, whose backs have just endured the stresses of pregnancy and birth, are particularly vulnerable. So are taller fathers and mothers who must bend farther than others to scoop up tots from playpens.

Most women are able to work safely, in some cases, until the day of delivery, depending on the type of work performed and their condition.
