Walking stability is an important factor that is related to working accidents at height. The understanding of the relationship between walking stability and walking conditions remains an unmet need. Therefore, this study aimed to investigate the effect of path height, width, and asymmetric conditions on the pressure and time information of the foot-ground interaction during walking. 12 subjects were required to walk at two height, three width, and asymmetric conditions. Plantar pressures during walking were measured with the F-scan insole sensors. The total pressures were normalized with body weight, and the temporal parameters were normalized with stance time. When the walking height increased, the plantar pressure at the “heel strike” phase did not change significantly, while that at “heel rise” and “toe off” phases significantly increased, and the “heel rise” occurred earlier, indicating a greater foot-ground interaction at the forefoot part of the sole. As the path width increased from 0.6 m to 1.2 m, the foot-ground interaction as well as the asymmetric effect approached to that of overground walking. The findings could help improve the risk assessment and footwear design.

“…In this context, the obtained results might be explained by an increase in anxiety and increased stiffness of muscles 61 , 62 . The phenomenon is often observed in at-height workers and is interpreted as changing postural strategy to be more conscious in circumstances of danger 24 , 63 .…”

“…When the CNS is affected by external demands—such as anxiety, e.g. at-hight work 23 , 24 or physical 6 and mental fatigue 25 —as well as internal demands like degeneration connected to involution processes 26 or cognitive demand such as during dual-task 27 this might have a significant impact on PS, and, in consequence, on falls/accidents.…”

The study aimed to evaluate the effect of sleep deprivation on postural stability among physically active young adults. The study involved 22 physical education students. Average velocities and spatial distribution of the center of pressure displacements were taken as indicators of postural stability (double and one-leg standing). Two-way ANOVA with two factors of repeated measurements—“session” (control-experimental) and “daytime” (evening-morning)—was used. For indicators of the spatial distribution of the center of pressure in double stance with eyes open and eyes closed, and for average velocities for measurements with eyes closed, statistically significant interaction effects were found (at least p < 0.01, ƞ2 > 0.36, power statistics > 0.90) with the general tendency of higher results in the morning in the session with sleep deprivation than in the control session. In one-leg standing, an increase of average velocities was observed in the control session, and no differences in the session with sleep deprivation (interaction effect: at least p < 0.01, ƞ2 > 0.37, power statistics > 0.90). Besides spatial distribution indicators in double stance, there were no statistical differences between evening-morning tests in the session with sleep deprivation. Despite significant interaction effects, only the results of spatial distribution indicators in double stance were higher in the morning than in the evening in the session with sleep deprivation. So, no clear decline in postural stability after sleep deprivation was observed. This may suggest that sleep deprivation prevents natural regeneration rather than significantly worsening postural stability among physically active adults. It’s possible that systematic physical activity might be one of the factors decreasing the risk of accidents among people exposed to sleep deprivation.

“…Serra et al 14 describe worker fitness as a multidimensional14–17 and dynamic concept, incorporating: (1) the worker’s physical and mental capacity, (2) the worker’s risk in relation to their job demands and the work environment and (3) ethical, economic and legal considerations. Evidence suggests that worker fitness plays a key role in preventing occupational accidents in high-risk occupations 1 16 18–22. The risk factors for falls from height can be classified as technical, organisational and human 23.…”

Mapping the evidence on assessment of fitness to work at heights: a scoping review protocol

2023

View full text Add to dashboard Cite

IntroductionFalls from height are a leading cause of serious injury and fatality globally. In South Africa, work at heights is regulated by occupational health and safety legislation, which places responsibility on employers to ensure their workers are fit for high-risk work. There is however no formal procedure or consensus on how fitness to work at heights should be assessed. This paper presents an a priori protocol for a scoping review that seeks to identify and map the current evidence base around the assessment of fitness to work at heights. It forms the initial phase of a PhD study aimed at developing an interdisciplinary consensus statement for assessing fitness to work at heights in the South African construction industry.Methods and analysisThis scoping review will follow the Joanna Briggs Institute (JBI) scoping review framework and will be guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping reviews (PRISMA-ScR) checklist. An iterative search will be conducted in a selection of multidisciplinary databases including, Proquest Central, PubMed, Scopus, Science Direct, Web of Science, PsychINFO and Google Scholar. Thereafter, searches for grey literature will be performed in Google.com and websites of various national and international agencies, governing bodies and professional organisations with an interest in occupational health and work at heights. Where appropriate, targeted requests for clarification for further information will be undertaken with information sources. A descriptive qualitative content analysis of the results will be conducted and a level of evidence rating will be assigned to each study using the JBI approach. This will allow us to provide some commentary on the rigour of the existing evidence base.Ethics and disseminationEthics approval for the PhD study was granted by the Research Ethics Committee, Faculty of Health Sciences, University of Pretoria, ethics reference number, 486/2021. Results of the scoping review will be submitted to a scientific journal for publication.Trial registration numberThis protocol is registered on the Open Science Framework at osf.io/yd5gw.
