Abstract Context Supplementation with vitamin D has the potential to both reduce and increase risk of falling, and parathyroid hormone (PTH) may contribute to fall risk. Objective To assess the associations of intra-trial mean circulating levels of 25-hydroxyvitamin D [25(OH)D] and PTH on incident falls in healthy older adults. Design Observational within a clinical trial. Setting The Bone Metabolism Laboratory at the USDA Nutrition Center at Tufts University. Participants 410 men and women age 65 years and older who participated in the 3-year Boston STOP IT trial to determine the effect of supplementation with 700 IU of vitamin D3 plus calcium on incident falls (secondary endpoint). Intra-trial exposures of 25(OH)D and PTH were calculated as the mean of biannual measures up to and including the first fall. Main outcome measures: incidence of first fall Results Intra-trial mean 25(OH)D was significantly associated with risk of falling in a U-shaped pattern; the range associated with minimal risk of falling was approximately 20-40 ng/ml. PTH was not significantly associated with risk of falling. Conclusions The findings highlight the importance of maintaining the circulating 25(OH)D level between 20 and 40 ng/ml, the range that is also recommended for bone health. At PTH levels within the normal range, there was no detectible independent association of PTH with fall risk.

This article reviews the use of wearable sensors for the monitoring of physical activity (PA) for different purposes, including assessment of gait and balance, prevention and/or detection of falls, recognition of various PAs, conduction and assessment of rehabilitation exercises and monitoring of neurological disease progression. The article provides in-depth information on the retrieved articles and discusses study shortcomings related to demographic factors, i.e., age, gender, healthy participants vs patients, and study conditions. It is well known that motion patterns change with age and the onset of illnesses, and that the risk of falling increases with age. Yet, studies including older persons are rare. Gender distribution was not even provided in several studies, and others included only, or a majority of, men. Another shortcoming is that none of the studies were conducted in real-life conditions. Hence, there is still important work to be done in order to increase the usefulness of wearable sensors in these areas. The article highlights flaws in how studies based on previously collected datasets report on study samples and the data collected, which makes the validity and generalizability of those studies low. Exceptions exist, such as the promising recently reported open dataset FallAllD, wherein a longitudinal study with older adults is ongoing.

The aim of this study was to compare the effect and durability of perturbation and vestibular exercises on balance and the risk of falling in people with visual impairment (VI). Thirty-six men with VI were divided into three groups, including a control and two experimental (perturbation and vestibular) groups. The experimental groups performed perturbation and vestibular exercises for 4 weeks and three sessions per week. Biodex balance system was used to assess balance and falling risk before and after training interventions. To evaluate the effects within and between groups at three levels of measurement: pre-test, post-test, and durability effect between three groups, repeated measures analysis of variance (ANOVA) and one-way ANOVA were used. Repeated measures ANOVA test showed that both experimental groups showed significant improvements in static balance, dynamic balance, and falling risk. In comparison between the groups, the results showed that in the post-test and durability stages, there was a significant difference between the groups and the perturbation exercise group had a greater effect on the dependent variables. Due to the effectiveness of exercises, it is recommended that people with VI pay attention to balance-based perturbation exercises to strengthen the somatosensory system and vestibular exercises to strengthen the vestibular system.

As humans, we constantly change our movement strategies to adapt to changes in physical functions and the external environment. We have to walk very slowly in situations with a high risk of falling, such as walking on slippery ice, carrying an overflowing cup of water, or muscle weakness owing to aging or motor deficit. However, previous studies have shown that a normal gait pattern at low speeds results in reduced efficiency and stability in comparison with those at a normal speed. Another possible strategy is to change the gait pattern from normal to step-to gait, in which the other foot is aligned with the first swing foot. However, the efficiency and stability of the step-to gait pattern at low speeds have not been investigated yet. Therefore, in this study, we compared the efficiency and stability of the normal and step-to gait patterns at intermediate, low, and very low speeds. Eleven healthy participants were asked to walk with a normal gait and step-to gait on a treadmill at five different speeds (i.e., 10, 20, 30, 40, and 60 m/min), ranging from very low to normal walking speed. The efficiency parameters (percent recovery and walk ratio) and stability parameters (center of mass lateral displacement) were analyzed from the motion capture data and then compared for the two gait patterns. The results suggested that step-to gait had a more efficient gait pattern at very low speeds of 10–30 m/min, with a larger percent recovery, and was more stable at 10–60 m/min in comparison with a normal gait. However, the efficiency of the normal gait was better than that of the step-to gait pattern at 60 m/min. Therefore, step-to gait is effective in improving gait efficiency and stability when faced with situations that force us to walk slowly or hinder quick walking because of muscle weakness owing to aging or motor deficit along with a high risk of falling.

Background. Protective facemasks are important for preventing the spread of COVID-19, and almost all Americans have worn them at least some of the time during the pandemic. There are reasonable concerns about some ill effects of mask-wearing, especially for people who wear masks for extended periods, and for the risk of falling as a result of visual obstruction. But there are also unsupported fears and objections stemming from misinformation and fueled by political disputes. Methods. The study analyzed the Consumer Product Safety Commission’s National Electronic Injury Surveillance System (NEISS) for 2020, using the product code for Respiratory Protection Devices, and calculated population incidence rates using Census data. Results. The NEISS included 128 cases, representing an estimated 5122 reported injuries in the population (95% CI 3322, 6922). The overall rate of injury reports was 1.54 per 100,000 U.S. residents (95% CI 1.00, 2.08). People over age 75 had higher rates than the population overall, with 5.27 injuries per 100,000 (95% CI 2.17, 8.37). The most common type of incidents involved facial injuries, rashes, falls, and those that might be considered anxiety-related. Conclusion. Wearing protective face masks is extremely safe, especially in comparison with other common household products, and in light of their protective benefits with regard to prevent the spread of COVID-19. This information may be useful for public health messaging, and for practitioners trying to increase compliance with mask-wearing guidance.

Background: In the management of hyperbilirubinemia in neonates, phototherapy is an important treatment modality. Photo-therapy can cause skin rashes, diarrhoea, increase in body temperature, retinal damage and bronze baby syndrome. Photo-therapy is thought to influence serum calcium levels by inhibiting pineal melatonin secretion. Aims and Objectives: The aim of this research was to see how photo-therapy affected serum calcium values in a term neonate. Materials and Methods: Over the course of six months, 74 neonates were studied in the neonatology department of a tertiary healthcare centre in Central India. Results: Calcium values fell in 77 % of the neonates in our sample, but only one case fell into significant symptomatic hypocalcemic range (1 percent). Conclusion: According to the findings, neonates who are receiving photo-therapy have a higher risk of falling into the hypocalemic range. As a result, neonates should be strictly observed for calcium shifts and treated appropriately.

Abstract Background Patients with stroke in rehabilitation wards are at an increased risk of falling. Although patients’ participation in establishing medical safety is considered crucial, there is limited evidence on their perspectives of falls. This study aims to comprehensively elucidate the subjective falling experience of patients with stroke who have been admitted to rehabilitation wards. Methods Twenty-three consecutive patients with stroke (44 to 90 years) who experienced a fall during hospitalisation were interviewed within 1 week after the fall, and thematic analysis was used to analyse the data. Results Five themes surrounding fall events were extracted from the narratives: ‘Psychological background before the action’, ‘Support for the action’, ‘Direct causes of the fall’, ‘Patients’ awareness after the fall’, and ‘Changes in attitudes and behaviours after the fall’. ‘Psychological background before the action’ comprised hastiness or hesitation to call for help. Participants often took an action based on ‘Support for the action’ derived from their past experiences of moving safely, their confidence, and/or motivation to challenge themselves to move. ‘Direct causes of the fall’ consisted of unfamiliar actions, training fatigue, the surrounding environment, reduced physical function due to paralysis, lack of attention, overconfidence in their ability, and insufficient prediction of falls. ‘Patients’ awareness after the fall’ consisted of re-affirming difficult movements, the need for rehabilitation, a reduced ability to move, an increased risk of falling, the need for attention while moving, a fear of falling, and a lack of lessons learned from falling. Finally, patients demonstrated ‘Changes in attitudes and behaviours after the fall’ such as embodying a positive attitude to cope with the risk of falling or behavioural changes to reduce the risk of falling. Conclusions Comprehensive information on patients’ perspectives before and after the fall was elucidated, uncovering many aspects including the psychological background for why patients engaged in risky behaviours resulting in falls, presence of positive thinking, and behaviour after the fall. By incorporating the patients’ views on fall incidences and their assessment, we can develop appropriate prevention strategies against falls.
