“…According to Park et al, there were no significant differences between dominant vision and nondominant vision in postural control using computerized dynamic posturography in the young subjects [18]. In our research, the corrected visual acuity of the participants was better than or equal to 20/20, i.e.…”

To compare the influences of monocular vision versus binocular vision on postural control, twenty-seven otherwise healthy adults, aged from 19 to 38 years, with corrected visual acuity of better than or equal to 20/20, were recruited. Body sway for standing 30 seconds on a force platform in 3 conditions was recorded for each participant: one with both eyes open (BEO), one with left eye open (LEO) and the other with both eyes closed (BEC). Postural stability was subsequently evaluated by measuring the total track length (TL) and surface area (SA) of center of pressure of body sway. The results show that the values of TL and SA of BEC were significantly greater than those of LEO and BEO. Moreover, the values of TL and SA of BEO were significantly smaller than those of LEO (p < 0.05, one-way repeated measures ANOVA and post hoc of Fisher's LSD procedure). The Romberg coefficient of LEO was also significantly greater than that of BEO (p < 0.05, paired sample t-test). We concluded that optimal binocular vision provides more information for keeping balance than monocular vision according to the results revealed in our study. Assessment of visual acuity is recommended before doing a posturographic test in the clinical setting. However, the long-term impact of blindness on controlling posture is uncertain and needs further investigation.

“…The result of the present study was partially consistent with the report that kinematic changes were found depending on the blockage and opening of the visual field in the motion of reaching 21 ) and the report that the positional control was not greatly dependent on the opening of the dominant eye or the non-dominant eye in young adults 22 ) .…”

“…Park et al 20 ) reported that the muscular activity of the gastrocnemius muscle was increased for balancing in the motion of reaching and that the lower limb muscular activity was increased when the non-dominant eye was open 22 ) . However, no significant difference was found in the present study because the results were similar between the conditions.…”

[Purpose] The aims of this study was to investigate mean velocity and angle of shoulder joint, activation of tibialis anterior and gastrocnemius according to both eyes, dominant eye and non-dominant eye condition during reaching task in normal adults. [Subjects and Methods] Our research recruited 24 participants (male 11, female 13) in Silla University. Participants were performed reaching out movement by conditions of both eye, dominants eye, non-dominants eye. The target was placed at 45 degree diagonal direction and distance far away 130% of their arm length. Kinetic analysis of the upper extremities was investigated by QUALISYS 3-dimensional motion analysis system. Muscle activation were measured by EMG during reaching tasks. The collected data were statistically processed using the SPSS for win version 20.0. [Results] There was a significant difference of shoulder joint velocity of flexion, abduction and internal rotation according to visual field condition during reaching tasks. There was no significant difference of shoulder joint angle and muscle activation according to visual field conditions during reaching tasks. [Conclusion] In conclusion, visual field has an influence on shoulder joint velocity. Therefore, the visual field may be to play an important role in reach performance.

“…Balance control is essential in all postural conditions, both static and dynamic, requiring integrity of neuromuscular system and an adequate muscle strength. Moreover, previous studies demonstrated the key role of visual inputs in achieving a steady posture control in normal subjects [ 10 , 11 ], especially in the elderly [ 12 , 13 ] and in subjects affected by neuromuscular diseases [ 14 – 17 ]. Furthermore, rehabilitation programs based on the recovery of visuomotor integration have been found useful in improving equilibrium [ 18 – 21 ].…”

Objectives. To assess the motor control during quiet stance in patients with established ankylosing spondylitis (AS) and to evaluate the effect of visual input on the maintenance of a quiet posture. Methods. 12 male AS patients (mean age 50.1 ± 13.2 years) and 12 matched healthy subjects performed 2 sessions of 3 trials in quiet stance, with eyes open (EO) and with eyes closed (EC) on a baropodometric platform. The oscillation of the centre of feet pressure (CoP) was acquired. Indices of stability and balance control were assessed by the sway path (SP) of the CoP, the frequency bandwidth (FB1) that includes the 80% of the area under the amplitude spectrum, the mean amplitude of the peaks (MP) of the sway density curve (SDC), and the mean distance (MD) between 2 peaks of the SDC. Results. In severe AS patients, the MD between two peaks of the SDC and the SP of the center of feet pressure were significantly higher than controls during both EO and EC conditions. The MP was significantly reduced just on EC. Conclusions. Ankylosing spondylitis exerts negative effect on postural stability, not compensable by visual inputs. Our findings may be useful in the rehabilitative management of the increased risk of falling in AS.
