ABSTRACT

Objective:

To explore the intervention effects of high and low audio-motor stimulation mode on attention and memory of elderly with mild cognitive impairment in rural areas.

Methods:

From September 2019 to May 2020, 80 subjects with mild cognitive impairment meeting the inclusion and exclusion criteria were selected and randomly divided into experimental group and control group according to the drawing lots, with 40 participants in each group.The experimental group was given high and low audio-motor stimulation mode training, and the control group was given finger exercises training.Before and after the intervention, sustained and selective attention were assessed using number cancellation test(NCT), E-Prime paradigm based on Stroop effect design, and memory was assessed using the Rivermead behavioral memory test, version 2 (RBMT-Ⅱ). SPSS 17.0 software was used to perform data statistics. The independent sample t test, paired sample t test and Mann Whitney U test were used for statistical analysis.

Results:

After intervention, the sustained attention index of the experimental group (0.86±0.48) was significantly higher than that of the control group (0.63±0.47, t=4.336, P<0.05). After intervention, the unanimous response time of the experimental group ((2 263.38±437.87) ms) and the reverse reaction time ((2 335.75±599.86) ms) were significantly lower than those of the control group ((2 703.95±506.34) ms, (2 667.43±585.38) ms) ( t=-4.068, -2.447, P<0.05). The consistent correct rate ((0.84±0.14)) and the reverse correct rate ((0.87±0.10))were significantly higher than those of the control group ((0.71±0.19), (0.73±0.15)) ( t= 3.571, 4.931, both P<0.05). RBMT-Ⅱ dimensions and total standard scores of the experimental group (19.00 (18.00, 20.00)) were higher than those of the control group (11.00 (10.00, 12.00))( Z=7.299, P<0.05).

Conclusion:

High and low audio-motor stimulation improves attention and memory in rural elderly with mild cognitive impairment.
