RESUMO
BACKGROUND: Effects of a multicomponent exercise programme have an impact on the physical, cognitive, and psychological domains in elderly community-dwellers. However, some individuals aged 65 years or more have not shown positive effects after the intervention as reported in similar research. The objective of this quasi-experimental study was to clarify the effectiveness of a multicomponent programme based on reality orientation therapy (ROT) on the physical performance, cognitive ability, and psychological state in the elderly. METHOD: Participants were recruited from the general public in 20 areas of Akita Prefecture, Japan, and they took part in each exercise programme for 90 min a day, once every 2 weeks, for 3 months, according to the group classification using cluster randomization into 20 cohorts in Akita. Physical, cognitive, and geriatric depression assessments were performed at baseline and after the 3-month intervention in both the ROT-based intervention group and the control group. RESULT: The final samples for analysis consisted of 31 participants in the control group and 30 participants in the intervention group. The results of the statistical analysis comparing the two groups showed that the 5-repetition sit-to-stand test was performed significantly faster (P < 0.05) and that the results of the word list memory (WM) test and the Symbol Digit Substitution Task also had significantly improved (P < 0.05) after the intervention in both groups. The WM score did not show an interactive effect between the group and time factors, but it had a significant main effect on time in both groups (P < 0.05). CONCLUSION: The results of our quasi-experimental study indicated that the multicomponent programme based on the ROT would be as effective as the original multicomponent programme combined with aerobic exercise and cognitive tasks, as highlighted in the WM.

OBJECTIVES: This study determined whether the individual intervention of using life story books (LSBs) improves apathy and verbal fluency in people with dementia (PWD). METHODS: The intervention group (n = 43) underwent 3 interviews in the 10 weeks following an initial assessment. Based on the information obtained, LSBs were developed; participants received individual interventions weekly, five times for four weeks. They also received a final assessment 12 weeks after the end of the intervention. Primary outcome measures comprised the Categorical Verbal Fluency Test (CFT) and the Neuropsychiatric Inventory-Nursing Home Apathy sub-item. The control group (n = 32) underwent initial and final assessments at intervals of 28 weeks while receiving the best care services. RESULTS: CFT scores for participants with mild to moderate dementia increased from 4.3 to 5.3 (P < .05) and the interaction effect of group and data collection timing was significant (p < .05). Apathy score for participants with severe dementia also improved from 4.5 to 2.5 (P < .05) immediately after the intervention period. CONCLUSIONS: LSB is a comprehensive communication tool that encourages apathy and verbal fluency. CLINICAL IMPLICATIONS: The use of LSB may allow caregivers to achieve intervention effects on apathy and verbal fluency in PWD.

AIM: To clarify the age-related changes in muscle elasticity or thickness of the lower extremities in older women, and to analyze their relationship with physical functions. METHODS: The muscle elasticity and thickness of the rectus femoris and medial head of the gastrocnemius of 102 young women (young group) and 221 elderly women (elderly group) were measured using ultrasonography. In the elderly group, physical functions, including knee extension strength, Timed Up and Go test, single-leg standing, maximum gait speed and Four Square Step Test were also measured. RESULTS: The elasticity of the rectus femoris and medial head of the gastrocnemius were significantly higher, but the muscle thickness of both muscles was significantly lower in the elderly group than in the young group (both P < 0.001). In the elderly group, the elasticity of the rectus femoris was significantly correlated with Timed Up and Go test, maximum gait speed and Four Square Step Test (ρ = 0.481, r = -0.387 and ρ = 0.401, respectively, all P < 0.001), and the medial head of the gastrocnemius was similar (ρ = 0.471, r = -0.489 and ρ = 0.422, respectively, all P < 0.001). The muscle thickness of the rectus femoris was significantly associated with knee extension strength (r = 0.444, P < 0.001). CONCLUSIONS: Older women showed age-related changes in high elasticity and atrophy of the rectus femoris and medial head of the gastrocnemius. The high elasticity of both muscles, not muscle thickness, was associated with dynamic balance and walking ability. Geriatr Gerontol Int 2019; 19: 61-65.

BACKGROUND: The circadian rhythm in older adults is commonly known to change with a decrease in physical activity. However, the association between circadian rhythm metrics and physical activity remains unclear. The objective of this study was to examine circadian activity patterns in older people with and without dementia and to determine the amount of physical activity conducive to a good circadian measurement. METHOD: Circadian parameters were collected from 117 older community-dwelling people (66 subjects without dementia and 52 subjects with dementia); the parameters were measured continuously using actigraphy for 7 days. A receiver operating characteristic (ROC) curve was applied to determine reference values for the circadian rhythm parameters, consisting of interdaily stability (IS), intradaily variability (IV), and relative amplitude (RA), in older subjects. RESULTS: The ROC curve revealed reference values of 0.55 for IS, 1.10 for IV, and 0.82 for RA. In addition, as a result of the ROC curve in the moderate-to-vigorous physical Activity (MVPA) conducive to the reference value of the Non-parametric Circadian Rhythm Analysis per day, the optimal reference values were 51 minutes for IV and 55 minutes for RA. However, the IS had no classification accuracy. CONCLUSIONS: Our results demonstrated the reference values derived from the circadian parameters of older Japanese population with or without dementia. Also, we determined the MVPA conducive to a good circadian rest-active pattern. This reference value for physical activity conducive to a good circadian rhythm might be useful for developing a new index for health promotion in the older community-dwelling population.
