“…In the present study, sporting activities and do-it-yourself and gardening activities were found to especially reduce the risk of falls. Sport and physical training improve the quality of postural control [39][40][41] by developing neurosensorial information sensitivity which promotes anticipatory postural adjustments. Practicing physical activity allows faster detection of destabilization and the organization of compensatory mechanisms to avoid falls.…”

Correlates of Occupational Injuries for Various Jobs in Railway Workers: A Case‐Control Study: Nearkasen Chau, et al. National Institute for Health and Medical Research (Inserm), Unit 420, Faculté de Medicine, France—Few studies have simultaneously addressed the role of occupational factors, individual characteristics and living conditions in occupational injuries, and to the best of our knowledge none on railway workers. This survey assessed the roles of these factors in various types of injuries and for various jobs in French railway workers. This case‐control study was conducted on 1,305 male workers with an occupational injury during a one‐year period and 1,305 male controls. A standardized questionnaire was administrated by an occupational physician. Data were analyzed by the logistic regression method. The significant factors found for all the injuries combined were: young age (<30 yr) (adjusted odds ratio 1.47, 95% CI 1.01–2.14), 5 yr or less in present job (1.43, 1.15–1.78), sleep disorders (1.30, 1.08–1.57), current smoker (1.27, 1.08–1.50), and no do‐it‐yourself or gardening activity (1.23, 1.02– 1.48). Young age, sleep disorders, and smoking were common for several types of injuries. The role of these factors differed between various job categories. Among injured workers sick leaves of eight days or over were more frequent in current smokers and overweight subjects. In conclusion, young age, lack of experience, job dissatisfaction, sleep disorders, smoking, and lack of physical activity increase the risk of occupational injuries. The risks induced were related with jobs. Preventive measures concerning work conditions and these factors could be conducted in railway workers generally, and especially in workers most at risk. The occupational physician could make workers more sensitive to these risks and help them to improve their living conditions during medical examinations.

“…Recent findings have also indicated that postural stability (Liu et al, 2001;Nakano et al, 2001;Avni et al, 2006) and motor control (Frey et al, 2004) are affected by sleep deprivation, though the mechanisms have yet to be determined. Some consider that the motor deficits are caused by alterations in the attentional state of the brain (Schlesinger et al, 1998;Fabbri et al, 2006). Other authors have proposed that detrimental postural effects are the result of daily circadian changes involving alertness (Nakano et al, 2001;Gribble and Hertel, 2004).…”

AbstractObjective: To investigate whether postural stability and adaptation differed after a normal night of sleep, after 24 h (24 SDep) and 36 h (36 SDep) of sleep deprivation while subjected to repeated balance perturbations. Also, to determine whether there was any correlation between subjective alertness scores and objective posturographic measurements. Lastly, to investigate the effects of vision on the stability during sleep deprivation. Methods: Body movements at five locations were recorded in 18 subjects (mean age 23.8 years) using a 3D movement measurement system while subjected with eyes open and closed to vibratory proprioceptive calf stimulation after a normal night of sleep, 24 and 36 SDep. Results: The clearest sleep deprivation effect was reduced ability to adapt head, shoulder and hip movements, both with eyes open and eyes closed. Additionally, several near falls occurred after being subjected to balance perturbations for 2-3 min while sleep deprived. Unexpectedly, postural performance did not continue to deteriorate between 24 and 36 h of sleep deprivation, but showed some signs of improvement. Subjective scores of sleepiness correlated poorly with actual changes in postural control performance. Conclusions: Sleep deprivation might affect postural stability through reduced adaptation ability and lapses in attention. Subjective alertness might not be an accurate indicator of the physiological effects of sleep deprivation. Significance: Sleep deprivation could increase the risk of accidents in attention demanding tasks. There is a need for objective evaluation methods to determine actual performance capacity during sleep deprivation.

“…Schlesinger et al [12] emphasised that complex balance movements require more concentration and attention, and therefore the sleep state of participants is important. In our study, the test performance did not show a difference at different times of the day for either leg in terms of chronotype.…”

Introduction. The aim of the study was to examine the effect of circadian rhythm on dynamic balance performance and to determine the role of physical activity level, body temperature, chronotype, and gender in this possible effect. Material andmethods. Forty-two young male and female subjects with different physical activity levels participated in the study. A dynamic equilibrium test, a Star Excursion Balance Test (SEBT), was conducted at 9:00, 13:00, and 17:00 on three different days with at least two days of interval between tests. The test scores were calculated by dividing the reaching distances by the leg length and multiplying the quotient by 100. The physical activity level and sleep state were evaluated using questionnaires. Before each test, body temperatures were measured orally. Results. The best SEBT scores were found at 13:00 and 17:00 in the male group and in the trained group. The body temperature changes increased parallel to SEBT scores. The scores for the non-dominant leg were found to be significantly different in posterior test directions, and those for the dominant leg were different in anterior directions. Chronotype did not affect the test results. Conclusions. Circadian rhythm was found to have an effect on dynamic balance performance. Body temperature, gender, and physical activity level were also found to play a role in this effect.
