Traditional Thai exercise (Ruesi Dadton) for improving motor and cognitive functions in mild cognitive impairment: a randomized controlled trial

Abstract

This study determined the effectiveness of a 12-week cycle of Ruesi Dadton (RSD) among older adults with mild cognitive impairment (MCI), for improving cognitive and physical performance. Seventy-six participants were included and were divided equally into two groups. A group performed RSD exercise for 60 min, 3 times/wk for 12 weeks, and the control group did not perform RSD exercise. The primary endpoint was cognitive function, as assessed by the Montreal cognitive assessment (MoCA), Mini-Mental State Examination, verbal fluency (VF) test, and trail making test parts A and B (TMT-A and TMT-B). The secondary endpoints were the Timed Up and Go (TUG) test, handgrip, and gait speed results, which were used to evaluate the physical function. There were significant differences in the TMT-B and handgrip scores (P< 0.05) between the two groups. Both groups had improved MoCA scores (P< 0.05) and normal walking speeds (P< 0.01). Additionally, the RSD group showed improved VF test (P< 0.01), TMT-B (P< 0.01), and TUG test (P< 0.05); a negative correlation was found between MoCA and TUG test (P< 0.05). However, high walking speed and handgrip (P< 0.05) worsened in the control group. RSD exercise resulted in relevant improvements in the cognitive and physical functions in MCI.
