“…To find the effects of the investigated postures on the possible preferential use of different sensory afferents, we examined the subjects with the manipulation of visual input. Such an experimental protocol provides unique opportunities to reveal how sensory and motor signals are integrated to control the upright body (Paillard, Bizid & Dupui, 2007; Kabbaligere, Lee & Layne, 2017; Rasman et al, 2018). However, the results failed to find any interactions between the postural condition and vision in any of the sway indices.…”

Background It is known that adolescent idiopathic scoliosis (AIS) is often accompanied by balance deficits. This reciprocal relationship must be taken into account when prescribing new therapeutic modalities because these may differently affect postural control, interacting with therapy and influencing its results. Objective The purpose was to compare postural control in girls with AIS while wearing the Chêneau brace (BRA) or performing active self-correction (ASC) with their postural control in a quiet comfortable stance. Methods Nine subjects were evaluated on a force plate in three series of two 20-s quiet standing trials with eyes open or closed; three blocks were randomly arranged: normal quiet stance (QST), quiet stance with BRA, and quiet stance with ASC. On the basis of centre-of-pressure (COP) recordings, the spatial and temporal COP parameters were computed. Results and Discussion Performing ASC was associated with a significant backward excursion of the COP mean position with eyes open and closed (ES = 0.56 and 0.65, respectively; p < 0.05). This excursion was accompanied by an increase in the COP fractal dimension (ES = 1.05 and 0.98; p < 0.05) and frequency (ES = 0.78; p = 0.10 and ES = 1.14; p < 0.05) in the mediolateral (ML) plane. Finally, both therapeutic modalities decreased COP sample entropy with eyes closed in the anteroposterior (AP) plane. Wearing BRA resulted in ES = 1.45 (p < 0.05) while performing ASC in ES = 0.76 (p = 0.13). Conclusion The observed changes in the fractal dimension (complexity) and frequency caused by ASC account for better adaptability of patients to environmental demands and for their adequate resources of available postural strategies in the ML plane. These changes in sway structure were accompanied by a significant (around 25 mm) backward excursion of the mean COP position. However, this improvement was achieved at the cost of lower automaticity, i.e. higher attentional involvement in postural control in the AP plane. Wearing BRA may have an undesirable effect on some aspects of body balance.

“…Chiba et al also reviewed the human standing posture control by visual, vestibular, somatosensory, and tactile inputs (Chiba et al, 2016). Kabbaligere et al studied the effect of visual and vestibular inputs on bipedal posture tasks and they found that sensory reweighting occurred when sensory input was disturbed (Kabbaligere et al, 2017). Claeys et al investigated how proprioception and visual information change the strategy required to maintain balance (Claeys et al, 2011).…”

Visual and Vestibular Inputs Affect Muscle Synergies Responsible for Body Extension and Stabilization in Sit-to-Stand Motion

The sit-to-stand motion is a common movement in daily life and understanding the mechanism of the sit-to-stand motion is important. Our previous study shows that four muscle synergies can characterize the sit-to-stand motion, and they have specific roles, such as upper body flexion, rising from a chair, body extension, and posture stabilization. The time-varying weight of these synergies are changed to achieve adaptive movement. However, the relationship between sensory input and the activation of the muscle synergies is not completely understood. In this paper, we aim to clarify how vestibular and visual inputs affect the muscle synergy in sit-to-stand motion. To address this, we conducted experiments as follows. Muscle activity, body kinematics, and ground reaction force were measured for the sit-to-stand motion under three different conditions: control, visual-disturbance, and vestibular-disturbance conditions. Under the control condition, the participants stood without any intervention. Under the visual-disturbance condition, the participants wore convex lens glasses and performed the sit-to-stand motion in a dark room. Under the vestibular-disturbance condition, a caloric test was performed. Muscle synergies were calculated for these three conditions using non-negative matrix factorization. We examined whether the same four muscle synergies were employed under each condition, and the changes in the time-varying coefficients were determined. These experiments were conducted on seven healthy, young participants. It was found that four muscle synergies could explain the muscle activity in the sit-to-stand motion under the three conditions. However, there were significant differences in the time-varying weight coefficients. When the visual input was disturbed, a larger amplitude was found for the muscle synergy that activated mostly in the final posture stabilization phase of the sit-to-stand motion. Under vestibular-disturbance condition, a longer activation was observed for the synergies that extended the entire body and led to posture stabilization. The results implied that during human sit-to-stand motion, visual input has less contribution to alter or correct activation of muscle synergies until the last phase. On the other hand, duration of muscle synergies after the buttocks leave are prolonged in order to adapt to the unstable condition in which sense of verticality is decreased under vestibular-disturbance.

“…The failure to observe the changes of CoP in present study might be explained by the difference of vibration frequency. The vibration frequency in present study was around 150 Hz, while some previous studies used between 60 to 100 Hz [41][42][43]. Therefore, a vibration frquency of 150 Hz may be less effective to stimulate muscle spindle and induce postural sway.…”

“…Another reason might relate to the area of the vibrator attached. The studies that placed a vibrator on the archilles tendon instead of the muscles to disrupt proprioceptive cue from the ankle and found the backwad sway [31] or the increase in the COP displacement and angular displacement of hip, knee, and ankle joints [43].…”

Postural balance is influenced by alteration of somatosensory inputs. Sound and vibratory senses, one of several human senses may assist the postural control in a specific impaired situation. The aim of this pilot study was to quantify the effect of sound and vibration on postural balance in healthy young adults. Ten healthy young subjects volunteered to participate in the study. The average age, weight, height, and body mass index were 21.88 ± 0.42 years, 56.21 ± 9.80 kg, 159.75 ± 5.20 cm, and 21.99 ± 3.52 kg/m2. They were assessed for standing postural balance on a force plate over 6 conditions of sound and vibration applications under vision was excluded by using a blindfold. Postural balance variables consisted of planar deviation of Center of Pressure (CoP) and the maximum ranges of CoP in the medio-lateral (ML) and antero-posterior (AP) directions. Two-way ANOVA was used to find the effect and interaction effect of sound and vibration on the postural balance variables. Further analyses of the variables were performed on a basis of each factor. Between sound conditions (no sound and open sound), the variables were analyzed by the paired t-test. In addition, the effect of vibration (no vibration, vibration on quadriceps, and vibration on gastrocnemius) on the variables were analyzed by the one-way repeated measure ANOVA. Results demonstrated no interaction effect and main effect of sound and vibration on the postural balance variables (p > 0.05). In addtion, no significant difference of the postural balance variables between sound conditions (p > 0.05) as well as among vibration conditions (p > 0.05). In conclusion, sound and vibration did not effect to the postural balance during standing in healty young adults.
