The primary purpose of this study was to assess the validity of two motion sensors in measuring steps in institutionalized older adults during daily life activities. Sixty-eight nursing home residents (85.8 ± 5.6 years) were equipped with a hip-worn and ankle-worn piezoelectric pedometer (New Lifestyles 2000) and with an arm-mounted multisensor (SenseWear Mini). An investigator with a hand counter tallied the actual steps. The results revealed that the multisensor and hip- and ankle-worn pedometer significantly underestimated step counts (89.6 ± 17.2%, 72.9 ± 25.8%, and 20.8 ± 24.6%, respectively). Walking speed accounted for 41.6% of the variance in percent error of the ankle-worn pedometer. The threshold value for accurate step counting was set at 2.35 km/hr, providing percent error scores within ± 5%. The ankle-worn piezoelectric pedometer can be useful for accurate quantification of walking steps in the old and old-old (> 85 years) walking faster than 2.35 km/hr.

Accurate Quantification

Applicable and accurate assessment methods are required for a clinically relevant quantification of habitual physical activity (PA) levels and sedentariness in older adults. The aim of this study is to compare habitual PA and sedentariness, as assessed with (1) a wrist-worn actigraph, (2) a hybrid motion sensor attached to the lower back, and (3) a self-estimation based on a questionnaire. Over the course of one week, PA of 58 community-dwelling subjectively healthy older adults was recorded. The results indicate that actigraphy overestimates the PA levels in older adults, whereas sedentariness is underestimated when compared to the hybrid motion sensor approach. Significantly longer durations (hh:mm/day) for all PA intensities were assessed with the actigraph (light: 04:19; moderate to vigorous: 05:08) when compared to the durations (hh:mm/day) that were assessed with the hybrid motion sensor (light: 01:24; moderate to vigorous: 02:21) and the self-estimated durations (hh:mm/day) (light: 02:33; moderate to vigorous: 03:04). Actigraphy-assessed durations of sedentariness (14:32 hh:mm/day) were significantly shorter when compared to the durations assessed with the hybrid motion sensor (20:15 hh:mm/day). Self-estimated duration of light intensity was significantly shorter when compared to the results of the hybrid motion sensor. The results of the present study highlight the importance of an accurate quantification of habitual PA levels and sedentariness in older adults. The use of hybrid motion sensors can offer important insights into the PA levels and PA types (e.g., sitting, lying) and it can increase the knowledge about mobility-related PA and patterns of sedentariness, while actigraphy appears to be not recommendable for this purpose.

Objective: To establish the level of independence of the older adult in carrying out the basic activities of daily living of institutionalized older adults. Methods: A quantitative investigation was carried out with a population of 112 older adults, who entered the study as part of the sample, 41 of them, distributed according to gender as 16 women and 25 men. On the other hand, the age range with the highest prevalence in the sample of older adults is between 75 and 84 years old. With the review of medical records and the application of the Barthel index. Results: in the activities of daily life and the level of dependency that is progressive, which leads the older person to a level of dependency that increases with age. The prevalence of these changes can be evidenced by determining the pathologies of Hypertension and Arthritis in the sample. Conclusions: The level of independence in the performance of daily life activities was qualified as independent in less than half of the older adults in the sample.

Walking Speeds

The purpose of this study was to conduct a comprehensive evaluation of the effect that walking speed, gender, leg length, motion sensor tilt angle, brand, and placement have on motion sensor step-counting error. Fifty-nine participants performed treadmill walking trials at 6 speeds while wearing 5 motion sensor brands placed on the anterior (Digiwalker, DW; Walk4Life, WFL; New Lifestyles, NL; Omron, OM), midaxillary (DW; WFL; NL; ActiGraph, AG), and posterior (DW, WFL, NL) aspects of the waistline. The anterior-placed NL and midaxillary-placed AG were the most accurate motion sensors. Motion sensor step-count error tended to decrease at faster walking speeds, with lesser tilt angles, and with an anterior waistline placement. Gender and leg length had no effect on motion sensor step-count error. We conclude that the NL and AG yielded the most accurate step counts at a range of walking speeds in individuals with different physical characteristics.

Chronic diseases such as diabetes, hypertension, cardiovascular disease, and cancer, may limit the older adults’ ability to execute daily life activities; generating tiredness and/or overload on the caregivers. Objective: To determine the existing relationship between tiredness, the caregiver and the effects on the caregiver’s health. Method: Quantitative analytic study. The sample was assembled with 123 family caregivers and 123 older adults with a chronic degenerative disease. The sampling method was non-probabilistic. Results and Discussion: It was found association between tiredness and care’s repercussions (r=.438, p<.01), this suggest that, the higher the fatigue presented by the caregivers, higher the repercussions in their health will be (r=.546, p<.01). Also, a correlation from the care given by the familiar and the repercussions on the caregiver’s health (r=.546, p<.01), indicating that, the more extensive and complex the care given, greater the affectation this will have on the caregiver´s health. The care was related with the tiredness allows us to affirm that the more extensive and complex the care, the more tiredness is perceived by the caregiver (r=.109, p<.01). Conclusion: The caregiver’s tiredness is high; it is associated with the overload of the care and has several repercussions on the health or the wellbeing and future interdisciplinary-based interventions.
