RESUMO
The purpose of this study was to evaluate the influence of a Greek traditional dance training program on the dynamic balance of individuals with mental retardation (MR). A total of 17 individuals participated in this study. Ten individuals with mild or moderate MR and 7 individuals with mild or moderate MR who studied in special schools were assigned to intervention (MR-I) and control (MR-C) groups, respectively. Pretraining and posttraining exercise tests were performed to determine the dynamic balance ability. Dynamic balance ability was measured by means of a balance deck (Lafayette, Lafayette, IN, USA) in 30-, 45-, and 60-second intervals. The MR-I group underwent a 16-week Greek traditional dance training program at a frequency of 3 times per week and for a duration of 45 minutes per season. Posttraining results showed that the individuals with MR in the MR-I group improved during treatment, from their baseline scores on dynamic balance measurements (30 seconds: p < 0.01, 45 seconds: p < 0.05, 60 seconds: p < 0.05). The MR-C group did not show any improvement between the 2 measurements. In conclusion, individuals with MR may be able to improve their dynamic balance when performing a systematic and well-designed Greek traditional dance training program.
