80 children from a school for the mentally retarded were divided into two groups, a control group receiving educational training in the school and an experimental group combining foot reflexotherapy and school training. Mentally retarded children were shown to improve significantly in height, weight, health states, social living abilities, and intellectual development when receiving foot reflexology as opposed to those not receiving treatment.Lingyun, Yuru, Zhao; Yang Yuru, Feng gu; Jiamo, Hao; Shuwen, Cao and Xiulan, Zhang, "Observation on Improvement of Feeble-Minded Children's Social Abilities by Foot Reflexo-Therapy," 1998 China Reflexology Symposium review, China Reflexology Association, Beijing, pp. 24 - 28
