“…Additionally, we also observed that most of the foot zones of the legally blind participants had no significant pressure differences compared to controls, except for the higher maximum pressures in the first and second metatarsal heads (M1 and M2 zones) in patients in the closed-eye condition. These differences could be attributed to the contribution of the acquired blind participants’ data [ 15 ]. The small number of significant differences indicates that mild disturbances in the motor control of the balance are present and maybe can be ignored in conventional evaluation of the balance.…”

“…Some research finds that people with visual deficits have impaired balance control [ 16 , 17 ], while other research finds minor or no differences in static and dynamic postural control between sighted and visually impaired subjects [ 13 , 18 , 19 , 27 ]. Subjects with altered binocular vision have been found to have significantly altered measures of foot plantar pressures, and blind subjects can have prolonged foot-to-ground contact during gait [ 15 , 24 ].…”

“…Maintenance of balance control in conditions of visual loss is aided by vestibular and proprioceptive inputs and is manifested via compensatory adjustments of postural weighting [13,14]. Since postural changes in standing position reflect modifications in our body weight load on the plantar surface, measurement of plantar pressure can be used to quantify the influence of visual input on posture control [15]. A variety of tools have been employed to quantify balance control, such as stabilometry, dynamometry, video system analysis, electromyography during the execution of quiet stance, tandem Romberg test, one leg stance, and reaction-time tasks [13,14,[16][17][18][19][20][21][22][23].…”

We investigated the impact of visual impairment on balance control. We measured the center of pressure (COP) between the two feet and plantar surface pressures on each foot in 18 normal-sighted participants and compared their data with measures from 18 legally blind participants, either acquired or congenital. Pressures were measured in open- and closed-eye conditions using a baropodometric resistive plate. In the eyes-open condition, there were no differences between the sighted and legally blind groups in COP displacement. However, participants with visual loss had significantly increased pressures in two metatarsal regions (M1 and M2 zones) of the plantar surface in both viewing conditions (p < 0.05). The differences in pressure measures between the normally sighted and legally blind groups could be attributed mainly to the subgroup of subjects with acquired impairment. Our findings suggest that subjects with visual impairment present increased metatarsal pressures (i.e. forefoot), not yet associated to anterior displacement of COP or impaired balance control.

“…Из трех основных компонентов сенсорного обеспечения устойчивости вертикальной позы систематическое изучение роли зрения началось раньше всего [23]. Отмечена корреляция между нарушениями равновесия и некоторыми глазодвигательными нарушениями, а также остротой зрения и расстоянием между глазами и наблюдаемым объектом [24][25][26]. В норме при закрывании глаз (например, во второй фазе пробы Ромберга) существенных позных колебаний не возникает, что говорит о достаточных сочетанных компенсаторных возможностях проприоцепторов и вестибуляров [27,28].…”

A quantitative assessment of stability (body balance, equilibrium) and sensory support of the upright position, with identification of the "contributions" from various sensory systems, is the basis for the force plate tests similar to the Romberg's test. The purpose of this paper is to describe the Romberg's test evolution from its introduction to objective quantitative force plate tests (stabilometry) in the context of studies into the sensory support of the upright position in humans. The use of force plates for quantitative characterization of the body balance in the upright position with changing sensory conditions has added a higher sensitivity and accuracy to this assessment, providing for a more precise differentiation of various conditions. The tests originating from the Romberg's one but performed on a force plate can be considered as a quantitative investigation into the functioning of the sensory systems participating in the support of the upright position, as well as a tool for the assessment of their isolated contributions and central integration. The value of such tests for clinical medicine is related to a higher level of verification of the body balance abnormalities in various disorders, with an improvement of diagnosis and potential for differential diagnosis. With these assessments being non-invasive, it is feasible to use them for evaluation of changes of the upright equilibrium over time under treatment and rehabilitation procedures in neurology, traumatology and orthopedics, otolaryngology, sports medicine and other areas.

“…The authors (19) report significant changes in plantar pressure in adults with hip osteoarthritis (OA / hip osteoarthritis) in the sense that they show a lower load on heels / rearfoot than healthy ones during static examination (standing still / standing). The use of baropodometry allows the identification of the connections between the dysfunctions of the musculoskeletal system and the visual problems, in those with unstable binocular vision being signaled significant differences between the total areas of the left leg vs. right leg, forefoot area, forefoot load and rearfoot load, according to (20). The postural stability is low when the examination of subjects is done with maximum mouth opening, when there is a lower load of the left calcaneus and a higher load on the left 5 metatarsal head, and the highest values are obtained for the testing situation at the time of swallowing (maximum intercuspation), according to (21).…”

The study aims to investigate the parameters offered by the baropodometric examination on a group of athletes practicing the martial art Karate Do (20 subjects, 16 girls and 4 boys, average age 13.55 ± 2.74, height 163 cm ± 8.47 , weight 54.50 kg ± 8.84, BMI (body index mass) of 20.46 ± 2.90 and seniority in sports activity of 5.27 years ± 2.74). The purpose of the research is to determine the changes related to the value of the plantar surfaces, the pressures for the dominant and non-dominant lower segments, the positioning of the pressure center in relation to the support polygon and the imbalances in the sole of the foot. The testing was performed using the FreeMed baropodometric platform and the FreeStep by Sensor Medica software, in the last week of February 2021, at the Research Center for Human Performance within the Faculty of Physical Education and Sports, “Dunărea de Jos” University from Galați. Results: Placing the maximum pressure point / P.max in the forefoot area is an exception, only one case being reported with this distribution, the rest having P.max located at the rearfoot level. Comparison of the averages between the variables recorded for the left foot vs. the right foot highlights higher values of the dominant / right foot, but these differences are significant only for the values of the plantar pressure in the forefoot area and for the total load on the entire plantar surface / total load (p <.05). The comparison between the averages of the surfaces and the loads of each separate foot (for the forefoot and rearfoot areas) highlights major differences only for the values of the contact surfaces, the forefoot area being significantly larger than the rearfoot area (p <.05). Close average values with small and insignificant differences are reported for each foot between the forefoot and rearfoot areas when comparing the body pressure / load percent and weight ratio percent, indicating a balanced pressure distribution between the front and back area for each leg. The investigation was also useful by detecting the existing imbalances at the plantar level, for one or both legs, being also reported cases of hollow, flat and mixed foot. These plantar disturbances can negatively affect all the overlying / upper joints, but especially the body posture, thus being able to cause pain in the lumbar region, limiting the performance activity and causing even the withdrawal of the athletes. We recommend that after identifying the syndromes at the ankle joint, to implement personalized plantar supports, which should be introduced in sports shoes in order to balance the architecture of the foot sole.
