摘要

Purpose: Age-related changes in neuromuscular control contribute to impairments in balance control and increase fall risks in older adults. Maintaining balance is based on the sensor, motor and cognitive system. Therefore, the purpose of this study was to detect the effect training period to compare the effects of a long and short training period (six and twelve weeks) on balance control in elderly. Methods: Twenty-three healthy older adults (mean age 69.5±5.5 yr.) performed 30 to 40 minutes sensorimotor training three times per week for 12 weeks. Three parameters about balance were observed including transversal X, sagittal Y and total body sway distance. The postural assessment system (POSTUROMED(superscript ®)) with 250 Hz was used to measure 20 seconds of body sways before, middle and after training (at 0, 6, 12-week). Various Postures were measured including standing naturally with eyes open and closed, standing with feet together as well as standing in a semi-tandem and a tandem stand. For the analysis the SPSS 12.0 statistical software was used; repeated measure ANOVA and Tukey HSD were conducted. Results: The 12-week long training period affected the outcome even more significantly than the 6-week short training period. In comparison with the 6-week training period, subjects decreased their transversal X, sagittal Y and total body sway distance in the natural standing position with eyes open and closed and feet together stand (p＜.05). Subjects also decreased their sagittal Y and total body sway distance in the semi-tandem stand (p＜.05). The tandem stand, however, only revealed significant difference on the sagittal Y body sway (p＜.05). Conclusion: the long period training in elderly has better effects on balance control than the short period training program.
