Developmental phase

Primary outcomes The screening instrument for the detection of mild cognitive impairment is compared before and after intervention for three months.
Key secondary outcomes The evaluation of the swallowing function effect is measured with a tongue pressure gauge and a spirometer.
In addition, evaluating the motor function improvement effect is autonomic nerve function measurement, another improvement effect is to evaluate QOL and investigate the activity.

Results We tested whether karaoke training improves cognitive skills and reduces the risk of physical function impairments. Engaging elderly people, especially those in care homes, with karaoke training exercises that are moderately physically challenging may be a key to slowing cognitive decline and preventing dysphagia by sarcopenia.

Baseline Characteristics Participants were recruited from care home residents. The care homes are residential facilities for elderly people aged 65 years and older, in particular elderly people with a low income and difficulties living at home because of physical problems, their environment, or their housing circumstances. 26 participants (mean age = 82.43 years), 78.26% were women and 56.52% had more than 12 years of education. Women had an average SMI of 5.79 kg/m2 (SD = 0.84). Men exceeded the AWGS cutoff value of 7.0 kg/m2 with an average of 7.56 kg/m2 (SD = 1.34). The average MoCA score for all participants was 24.42 (SD = 4.13) and 57% of participants scored 25 points or less. Therefore, these indexes suggested participants were in the sarcopenia and MCI zones of these measures.
Participant flow Measures of cognitive and physical function were taken before the start and after the end of the program. Participants also completed a series of cognitive and physical function tests before beginning the program schedule (Pre-test). After 12 weeks, participants were re-examined using the same neuropsychological and behavioral tests (Post-test).
Randomization into the intervention or control group was conducted after the participants provided informed consent (n = 26).
The karaoke training program ran for 1 hour, once a week for 12 consecutive weeks on weekday afternoons at the care home, and homework of 1 hour was given each week.
For the control group, Scratch art sessions were held at the care home once a week for 12 weeks on consecutive weekday afternoons and lasted half an hour. Homework was to complete one artwork per week.
Adverse events None
Outcome measures Cognitive Function: Montreal Cognitive Assessment (MoCA) and Frontal Assessment Battery at bedside (FAB)
Physical Function: Tongue pressure and pulmonary function
Psychological Measures: Geriatric Depression Scale (GDS) and the Life Satisfaction Index-K (LSI-K) to assess quality of life (QOL)
