The Parellis have been subject to criticism because in most of their materials, they do not wear equestrian helmets and have published statements indicating they did not personally advocate their use other than for certain high-risk activities. In 2009 they amended their position, by publishing a statement on Facebook advocating helmet use for beginners, requiring it for children under 18 at their own facility, and advising all riders "to thoroughly evaluate their situation". , they still do not advocate helmets for all riders in spite of Linda Parelli having been "knocked out" as a result of a fall from a horse that stumbled in May 2009.
