Translation and Psychometric Properties of the Portuguese Version of the Timed Instrumental Activities of Daily Living (TIADL).

(1) Background: to examine the psychometric properties of the Portuguese version of the Timed Instrumental Activities of Daily Living (TIADL) in nursing home residents. (2) Methods: Fifty-two participants (85.8 ± 4.2 years) were assessed on two occasions, 10-14 days apart. The same rater administered all assessments. Internal consistency was analysed through Cronbach's α. The reliability was estimated using the intraclass correlation coefficients (ICCs), and the standard error of the mean (SEM) was used to estimate the minimal detectable change (MDC). Construct validity was determined by Spearman's correlation coefficients. (3) Results: For internal consistency, Cronbach's α (0.81) revealed high internal reliability. All of the subtests demonstrated good or excellent reliability and also presented acceptable measurement precision, considering the criterion SEM < SD/2. According to Spearman's rho, correlations with the Portuguese version of the TIADL, the Useful Field of View test, and semantic and phonemic fluency tests were significant, with moderate positive and negative correlations (0.4 < rs < 0.69). (4) Conclusions: The Portuguese version of the TIADL had good to excellent test-retest reliability (ICC > 0.90) and acceptable measurement precision. This test could be a valuable clinical tool for assessing actual performance in instrumental activities of daily living in nursing home residents.

Physical and Motor Fitness Tests for Older Adults Living in Nursing Homes: A Systematic Review.

This systematic review aimed to identify the physical/motor fitness tests for nursing home residents and to examine their psychometric properties. Electronic databases were searched for articles published between January 2005 and October 2021 using MeSh terms and relevant keywords. Of the total of 4196 studies identified, 3914 were excluded based on title, abstracts, or because they were duplicates. The remaining 282 studies were full-text analyzed, and 41 were excluded, resulting in 241 studies included in the review. The most common physical component assessed was muscle strength; 174 (72.2%) studies assessed this component. Balance (138 studies, 57.3%) and agility (102 studies, 42.3%) were the second and third components, respectively, most widely assessed. In this review, we also describe the most used assessment tests for each physical/motor component. Some potentially relevant components such as manual dexterity and proprioception have been little considered. There are few studies assessing the psychometric properties of the tests for nursing home residents, although the data show that, in general, they are reliable. This review provides valuable information to researchers and health-care professionals regarding the physical/motor tests used in nursing home residences, helping them select the screening tools that could most closely fit their study objectives.

Test-retest reliability of upper-limb proprioception and balance tests in older nursing home residents.

AIM: To examine the test-retest reliability of two upper-limb proprioception tests (Weight Detection Test, or WDT, and Arm Ruler Positioning Test, or ARPT) and two balance tests (Functional Reach Test, or FRT, and Timed Up and Go test, or TUG) in older nursing home residents. METHODS: Fifty-three nursing home residents (85.9 ± 3.9 years) participated in this study. Outcome measures were assessed on two occasions, 10-14 days apart. The same rater administered all tests. The relative reliability was estimated using the intraclass correlation coefficients (ICCs) with a two-way mixed-effects model. The absolute reliability was analyzed using the standard error of the mean (SEM) to estimate the minimal detectable change (MDC) at the 95 % confidence level. Systematic bias was studied using the paired-samples t-test or the Wilcoxon signed-rank test. RESULTS: The WDT (ICC = 0.84), ARPT (ICC = 0.87) and FRT (ICC = 0.85) had good relative reliability, and the TUG (ICC = 0.99) had excellent reliability. Our results suggest acceptable measurement precision: the SEMs were equal to 1.0 points, and 0.3 cm, 1.5 cm, and 0.5 s for the WDT, ARPT, FRT, and TUG, respectively. The mean difference between sessions was 0.3 points (1.4 %; w=-1.37, p = 0.17) in the WDT, 0.1 cm (-0.74 %; t = 0.41, p = 0.68) in the ARPT, 0.1 cm (0.45 %; w=-0.33, p = 0.74) in the FRT, and 0.2 s (1.37 %; w=-2.28, p = 0.02) in the TUG. CONCLUSIONS: This study showed that the four field-usable motor tests had good to excellent test-retest reliability and had acceptable measurement precision in older nursing home residents. These tests could be valuable clinical tools for assessing proprioception and balance in nursing home residents.

Exercise merging physical and cognitive stimulation improves physical fitness and cognitive functioning in older nursing home residents: a pilot study.

The main purpose of this pilot study was to examine the feasibility and the effects of a multimodal exercise intervention on the physical and cognitive functioning of institutionalized older people. Twenty-one older adults (83.5 ± 4.9 years) living in two nursing home residences, were tested on two occasions 4 weeks apart to establish a baseline measure, and then engage in the exercise program twice weekly for 8 weeks. Participants were tested again after the exercise program. Almost all physical fitness and cognitive tests were unchanged at baseline measures, but after the exercise program, significant improvements (p < 0.05) were found in all physical fitness variables (strength, cardiorespiratory endurance, flexibility and balance) and in the majority of cognitive variables (visual attention, executive functioning and information processing speed). Exercise merging physical and cognitive stimulation could have broad impacts in the individual's level of functioning and should be promoted in nursing home residences for the elderly.
