“…This result suggests that it may not be worthwhile to push patients to increase their physical activity once dementia symptoms have already reached a severe stage. It is necessary to consider other factors such as rest–activity rhythm, 36 and whether such activities are meaningful for the person 37 in examining physical activity in patients with severe dementia.…”

Background: The authors examined associations between physical activity, cognitive function, activities of daily living, and behavioral and psychological dementia symptoms (BPSD) in severe and moderate dementia. Methods: A cross-sectional study was conducted to assess severe and moderate dementia groups according to the Clinical Dementia Rating. An actigraphy measured physical activity. Other measures included Mini-Mental State Examination, Cognitive Test for Severe Dementia, Hyogo Activities of Daily Living Scale, and Neuropsychiatric Inventory-Nursing Home. Results: Sixty-three participants were assessed (mean age = 89.3 ± 6.4). Physical activity was not associated with cognitive function among participants with severe dementia, although there was a trend-level association with cognitive function among those with moderate dementia. Physical activity was significantly associated with BPSD, specifically agitation/aggression symptoms, for participants with severe dementia, and there was a trend-level association with anxiety for participants with moderate dementia. Conclusions: Physical activity appears to be associated with BPSD among individuals in the advanced stages of dementia.

“…The AWS detects the acceleration over 0.5 G, and M10 represents the mean counts/hour of the most active 10-hour period in one day. M10 is a standard parameter that reflects rest-activity patterns on consecutive days in the participant's living environment [9][10][11][12][13] .…”

Recent studies have reported the effectiveness of robotic rehabilitation of paralyzed upper limbs in stroke patients. For example, the Single-Joint Hybrid Assistive Limb has been shown to improve upper limb impairments. However, limited data are available on the effectiveness of robotic rehabilitation of the upper limb with regards to daily living. In this case study, an accelerometer was adopted to examine whether rehabilitation using the Single-Joint Hybrid Assistive Limb improved upper limb activity during daily living in a stroke patient. [Participant and Methods] The participant was a 69-year-old male diagnosed with stroke and left hemiparesis. The Single-Joint Hybrid Assistive Limb was applied to the participant's elbow on the paralyzed side. The participant wore an accelerometer on each wrist to measure the activities of the upper limbs. Clinical tests of the paralyzed upper limb were also performed. [Results] The activity of the paralytic limb was significantly higher after Single-Joint Hybrid Assistive Limb intervention than before the intervention. On the other hand, none of the results of the clinical tests changed beyond a clinically important difference. [Conclusion] The Single-Joint Hybrid Assistive Limb could be useful for promoting active use of a paralyzed upper limb in daily living. In addition, an accelerometer could be especially useful for evaluating the effects of robotic rehabilitation.

“…A total of 9 (27%) studies reported their quantification of different levels of HPA intensity, among which 1 (11%) reported very light physical activity, with counts per minute (CPM) ranging between 145 and 274 [50]. Moreover, 6 (66%) studies quantified light physical activity differently, including a metabolic equivalent (MET) ranging between 1.6 and 3 [40], 1.5 and 2.9 [53], and 1 and 3 [54] and CPM between 150 and 2689 [52], 100 and 1951 [55], and 100 and 2019 [34]. Another 4 (44%) studies characterized moderate physical activity, including an MET between 3 and 6 [40,53] and CPM between 1952 and 5742 [55] and 2020 and 5998 [34].…”

“…These findings highlight how the algorithm applied can alter results and emphasize the importance of validating the devices and methods used within a population with cognitive impairments. It should be noted that over half (n=17, 51%) of the studies included in this review did not report or cite information regarding the validity of the devices or methods used [31,33,35,39,40,42,43,46,48,49,51,53,54,59,[61][62][63]. Of those that did, devices and methods were validated in older adults [36,37,41,52,56,60], general adults [15,34,38,44,45,57,64], middle-aged females [50], people with Parkinson disease [37], and people with dementia [55].…”

Background Participating in habitual physical activity (HPA) can support people with dementia and mild cognitive impairment (MCI) to maintain functional independence. Digital technology can continuously measure HPA objectively, capturing nuanced measures relating to its volume, intensity, pattern, and variability. Objective To understand HPA participation in people with cognitive impairment, this systematic review aims to (1) identify digital methods and protocols; (2) identify metrics used to assess HPA; (3) describe differences in HPA between people with dementia, MCI, and controls; and (4) make recommendations for measuring and reporting HPA in people with cognitive impairment. Methods Key search terms were input into 6 databases: Scopus, Web of Science, Psych Articles, PsychInfo, MEDLINE, and Embase. Articles were included if they included community dwellers with dementia or MCI, reported HPA metrics derived from digital technology, were published in English, and were peer reviewed. Articles were excluded if they considered populations without dementia or MCI diagnoses, were based in aged care settings, did not concern digitally derived HPA metrics, or were only concerned with physical activity interventions. Key outcomes extracted included the methods and metrics used to assess HPA and differences in HPA outcomes across the cognitive spectrum. Data were synthesized narratively. An adapted version of the National Institute of Health Quality Assessment Tool for Observational Cohort and Cross-sectional Studies was used to assess the quality of articles. Due to significant heterogeneity, a meta-analysis was not feasible. Results A total of 3394 titles were identified, with 33 articles included following the systematic review. The quality assessment suggested that studies were moderate-to-good quality. Accelerometers worn on the wrist or lower back were the most prevalent methods, while metrics relating to volume (eg, daily steps) were most common for measuring HPA. People with dementia had lower volumes, intensities, and variability with different daytime patterns of HPA than controls. Findings in people with MCI varied, but they demonstrated different patterns of HPA compared to controls. Conclusions This review highlights limitations in the current literature, including lack of standardization in methods, protocols, and metrics; limited information on validity and acceptability of methods; lack of longitudinal research; and limited associations between HPA metrics and clinically meaningful outcomes. Limitations of this review include the exclusion of functional physical activity metrics (eg, sitting/standing) and non-English articles. Recommendations from this review include suggestions for measuring and reporting HPA in people with cognitive impairment and for future research including validation of methods, development of a core set of clinically meaningful HPA outcomes, and further investigation of socioecological factors that may influence HPA participation.
