Purpose The purpose of this study was to investigate the possible effects of smartphone usage in the biomechanical balance system. Method Twenty-five healthy young adults (10 men, 15 women) between the ages of 18 and 25 years without balance problems were included in the study. Sensory organization, adaptation, rhythmic weight shift, and functional limitation tests (unilateral stance, sit to stand, walk across, tandem walk, step quick turn, step up down, forward lunge) have been applied. Results Significant results were obtained in parameters of sensory organization, tandem walk, walk across, and unilateral stance tests ( p < .05). Conclusion The effects of using smartphones on postural control and balance in different circumstances, such as standing and walking, must be comprehensively determined to prevent accident.

Relevance.Compared with economically developed countries, Russia has a high risk of fires. In 2005–2017 in (175.8 ± 9.0) thousand fires were reported in Russia annually, with (81.1 ± 5.3) thousand people rescued, (12.6 ± 0.9) thousand died and (12.1 ± 0.4) thousand injured. The average annual direct damage from fires was (13.4 ± 1.1) billion rubles. The experienced extreme and emergency situations have a particularly significant impact on the functional status and health of an older person.Intention.The purpose of this work is to identify the features of the components of postural balance in older women who have survived a fire.Methodology.94 women aged 60–69 years were examined. The study group included women who, as a result of the fire, lost (in part or in full) their possessions and housing (fire victims). The comparison group randomly included women without any extreme situations (fire hazard, crime, road traffic, as well as the death of close relatives) over the past two years. To assess the quality of the equilibrium function, posture control strategy and sensory organization of postural control, we conducted the Sensory Organization Test (SOT) of the computer dynamic posturographic complex Smart Equitest Balance Manager.Results and discussion.Based on the SOT analysis, it was found that stressful situations associated with extreme or emergency situations experienced by older women influence the components of their postural balance. These changes included a decrease in the quality of the equilibrium function in functional tests 1, 2, 3, 5, 6 for fire victims; a decrease in the postural strategy in tests 5 and 6; a decrease in the resulting assessments of both the quality of the equilibrium function and the strategies for maintaining the posture of the entire SOT, as well as the degree of participation of vestibular information in the balance control.Conclusions.In female fire victims, the components of postural control change: the quality of the equilibrium function decreases, the strategy of maintaining posture deteriorates.

Introduction: Sensory information from vestibular, visual, proprioception, and feet contribute on postural control. Plantar afferent contribution comes from the tactile and nociceptive cues of the plantar sole. Nociceptive capacity of plantar irritating stimulus (NCPIS) is one of the foot problems that induce nociception. Objective: Was to determine the postural impact of sensory input flow modifications induced by foam in people with and without nociceptive plantar irritating stimuli in different ages (children, adolescents, and adults). Method: 120 participants with (NP) and X without (Ct) NCPIS in different age group were evaluated (20 subjects in each age group and conditions). Postural balance assessment was performed during two-legged stance test using a force platform. Postural recoding was performed with eyes open in two conditions: on a hard surface and on a foam surface. The postural balance parameter analyzed was center of pressure area and variance of speed. Results: Area and variance of speed in control group increased, whereas decreased in NP subjects. No differences were observed for mean speed. In the Ct group, nociceptor and mechanoreceptor afferent sensations on foam induced postural variation with more oscillations (area and speed). Conclusion: NCPIS influenced postural control, and this foam neutralization of afferent nociception induced a new sensory organization. Foam surface imitated afferent plantar sensory information, induced postural variation as measured by CoP parameters with increasing postural control in subjects without NCIPS and decreasing postural control in subjects with NCPIS.

Abstract Background Sit-to-stand (STS) is a complex movement that requires successful postural control. Aging is a normal part of human life that leads to weakness of sensory capabilities, resulting in diminished postural control. Therefore, STS movement is a challenging task for the elderly. Local tendon vibration (LTV) can be utilized to assist STS of the elderly by improving postural control. Many studies have revealed that the LTV has various physiological positive effect. However, previous studies did not consider subjects’ individual difference for properties of applied LTV. Also, there are almost no studies to assist and to improve elder’s STS movement. Thus, the purpose of this study was to examine the influence of lower limb LTV on postural sway during STS in the elderly, and to examine whether a specific vibration frequency can increase postural control in the elderly. Results The common characteristic differences between the elderly and younger population during STS movement were analyzed. In addition, the effect of vibration on the center of mass (COM) and the center of pressure (COP) variable responses in young adults and the elderly were investigated. As a result, the elderly exhibit larger COP sway area and higher COP mediolateral (ML) displacement than the young adults. In addition, the elderly generally have lower COM velocities in all directions compared to the young adults. It was found that COP and COM related to postural stability are affected when LTV of the 180 Hz, 190 Hz and 250 Hz is applied to the elderly. Particularly, the 190 Hz vibration induced significant reduction in COP sway area and COP ML displacement. Conclusions These results mean that the LTV contributes to stability of elders’ STS movement by reducing postural sway. Furthermore, a reduction of postural sway depends on frequency of the LTV. These findings suggest that individual response to characteristics of vibration must be considered, and imply that the LTV can be used as rehabilitation therapy to improve postural control in the elderly, and utilized in motion assistive devices to deliver apt vibration frequencies.

This study aimed to investigate the relationship between back muscle strength and proprioception or mechanoreceptor control strategies used for postural balance in elderly adults with lumbar spondylosis. The displacement of the center of pressure (COP) excursion was determined in 24 elderly adults with lumbar spondylosis and 24 healthy young adults while the participants were standing upright on a balance board with their eyes closed. Vibratory stimulations of 30, 60, and 240 Hz were applied to the gastrocnemius (GS) and lumbar multifidus (LM) muscles to evaluate the effect of different proprioceptive signals on postural control. Back muscle strength was evaluated. Spearman’s rank correlation analysis was performed to determine the relationship between back muscle strength and significant COP excursion. Compared with young adults, elderly adults with lumbar spondylosis showed an increase in COP excursion displacement when a vibratory stimulation of 240 Hz was applied to the GS (P = 0.002) and LM muscles (P < 0.001). LM stimulation at 240 Hz was significantly associated with back muscle strength (P = 0.038). Postural control assessment with 240-Hz mechanoreceptor stimulation of the trunk could be a good indicator of postural instability due to over-dependence on mechanoreceptors and back muscle weakness in elderly adults with lumbar spondylosis.

Balance problems are one of the most frequent symptoms in patients with Fibromyalgia Syndrome (FMS). However, the extent and nature of this balance disorder are not known. The objective of this work was to determine the best evidence for the alteration of postural balance in patients with FMS and analyze differences with healthy controls. To meet this objective, a systematic review with meta-analysis was performed. A bibliographical search was carried out in PubMed Medline, Scopus, Web of Science, CINAHL and SciELO. Observational studies that assessed postural balance in patients with FMS compared to healthy subjects in baseline conditions, were selected. In a random-effect model, the pooled effect was calculated with the Standardized Mean Difference (SMD) and its 95% confidence interval (CI). Nineteen studies reporting data of 2347 participants (95% female) were included. FMS patients showed poor balance with a large effect on static (SMD = 1.578; 95% CI = 1.164, 1.992), dynamic (SMD = 0.946; 95% CI = 0.598, 1.294), functional balance (SMD = 1.138; 95% CI = 0.689, 1.588) and on balance confidence (SMD = 1.194; 95% CI = 0.914, 1.473). Analysis of the Sensory Organization Test showed large alteration of vestibular (SMD = 1.631; 95% CI = 0.467, 2.795) and visual scores (SMD = 1.317; 95% CI = 0.153, 2.481) compared to healthy controls. Patients with FMS showed worse scores for different measures of postural balance compared to healthy controls. Concretely, FMS patients appear to have poor vestibular and visual scores with a possible somatosensory dependence.

The role of vision in postural control is crucial and is strictly related to the characteristics of the visual stimulus and to the performance of the visual system. The purpose of this investigation was to evaluate the effects of chronically reduced visual cues upon postural control in patients affected by Congenital Nystagmus (CN). These patients have developed since birth a postural strategy mainly based on vestibular and somatosensorial cues. Fifteen patients affected by CN and 15 normal controls (NC) were enrolled in the study and evaluated by means of dynamic posturography. The overall postural control in CN patients was impaired as demonstrated by the equilibrium score and by the changes of the postural strategy. This impairment was even more enhanced in CN than in NC group when somatosensorial cues were experimentally reduced. An aspecific pattern of visual impairment and a pathological composite score were also present. Our data outline that in patients affected by CN an impairment of the postural balance is present especially when the postural control relies mainly on visual cues. Moreover, a decrease in accuracy of the somatosensory cues has a proportionally greater effect on balance than it has on normal subjects.
