“…The results derived from this study show that women with FMS have impaired postural control compared with their healthy counterparts. These results are consistent with previous studies [ 9 – 11 , 13 , 24 ] but also yield some new findings about the postural control strategy. In general, there is a significant increase in the values of the linear variables (i.e.…”

“…Specifically, the Ellipse values were an average of 2.03 times higher in women with FMS than in healthy women. This result means that the COP trajectory covers a larger area in this population while standing and it is consistent with the results of a previous study conducted in women with fibromyalgia that reported a similar increase in the area in a bipedal test with eyes open [ 11 ]. It also coincides with the results of previous studies conducted in people with Multiple Sclerosis [ 17 ] or vestibular system problems [ 50 ].…”

“…So far, several studies have used objective devices to assess postural control in this population [ 8 – 11 ] using different tests that discriminated which of the different sensory inputs that are responsible for postural control (i.e. visual, proprioceptive and vestibular systems) were impaired.…”

“…visual, proprioceptive and vestibular systems) were impaired. All of them explored the impact of FMS on postural control variables in the time-domain, showing a larger area and higher velocity of the center of pressure (COP) [ 11 , 12 ] or an altered postural stability rate in FM patients [ 8 – 10 , 13 ] compared with healthy population. Nevertheless, although the postural control system is considered a non-linear system, where reactions are not proportional to the applied stimuli [ 14 , 15 ], none of the studies in this population have used non-linear variables to the assessment of the postural control.…”

The main goal of this cross-sectional study was to detect whether women with fibromyalgia syndrome (FMS) have altered postural control and to study the sensory contribution to postural control. We also explored the possibility that self-induced anxiety and lower limb strength may be related to postural control. For this purpose, 129 women within an age range of 40 to 70 years were enrolled. Eighty of the enrolled women had FMS. Postural control variables, such as Ellipse, Root mean square (RMS) and Sample entropy (SampEn), in both directions (i.e. mediolateral and anteroposterior), were calculated under five different conditions. A force plate was used to register the center of pressure shifts. Furthermore, isometric lower limb strength was recorded with a portable dynamometer and normalized by lean body mass. The results showed that women with FMS have impaired postural control compared with healthy people, as they presented a significant increase in Ellipse and RMS values (p<0.05) and a significant decrease in SampEn in both directions (p<0.05). Postural control also worsens with the gradual alteration of sensory inputs in this population (p<0.05). Performing a stressor dual task only impacts Ellipse in women with FMS (p>0.05). There were no significant correlations between postural control and lower limb strength (p>0.05). Therefore, women with FMS have impaired postural control that is worse when sensory inputs are altered but is not correlated with their lower limb strength.

Alteration of Postural Balance in Patients with Fibromyalgia Syndrome—A Systematic Review and Meta-Analysis

et al. 2021

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.

Background The popularity of mobile gaming among adults has raised concerns about the adverse health effects of localized muscle and eye fatigue. This study aimed to investigate how arm support and mobile game control characteristics affect muscle and eye fatigue, and postural changes. Methods Twelve subjects, ages 21–24 years old, were recruited to play a mobile game for 60 min. Participants used two postures (sitting with and without arm support) and two game control modes (touch and rocker). Electromyography measured the abductor pollicis brevis, the upper trapezius, and the extensor carpi radialis muscles. A motion capture system was employed to assess postural changes. Self‐reported fatigue was measured using Borg's scale and Heuer's questionnaire. Results Arm support had a significant effect on muscle fatigue and posture, including a lower rating of perceived exertion in the shoulder (p < .05) and arm (p < .01), an increase in neck and trunk forward flexion between 22% and 34%, an increase in forearm bearing angle of 97.63%, and a decrease in upper arm bearing angle of 25.94% in the group without arm support. Blink for touch mode was 10.57% higher than for rocker mode. Conclusion Arm support was effective in reducing fatigue in the arm and shoulder, but not in the hand. Compared to rocker mode, touch mode increased the visual burden and accelerated visual fatigue. This study provides an understanding of the association between playing mobile games and fatigue, which can help prevent muscle and visual fatigue in mobile gaming.
