Nancy. M. Watson, PhD, RN, who conducted the studies said "It's been very well documented with infants that a gentle repetitive motion has a soothing effect. We've shown that the same is true in an older population that is emotionally distressed." She is an Associate Professor at the University of Rochester School of Nursing and the Director of Center for Clinical Research on Aging. Their research showed that seniors could literally rock away their anxiety and depression. The patients required less medication and their balance improved as well. Further benefits included a happier nursing home staff. Families of rocking seniors were happier because their loved ones were happier. One intervention (rocking) produced six benefits, and effected many people in a positive way.
