“…The underlying cause of impaired postural control is considered multifactorial albeit strongly associated with vestibular dysfunction and defects in certain structures of the central nervous system (Hawasli, Hullar & Dorward, 2015; Gauchard et al, 2001; Byl et al, 1997). As the medial vestibulospinal tract controls the axial muscles (Pialasse et al, 2013), changes in the brain stem or sensorimotor cortex during the critical preadolescent and adolescent period of growth can impair sensorimotor integration and therefore lead to inappropriate trunk muscle activities, spine deformation, and greater instability. Hence, it is hypothesized that reduced balance control in AIS patients may be caused by either impaired vestibular information transfer or sensorimotor processing (Shi et al, 2013).…”

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.

“…Five studies demonstrated a direct relationship between an anatomical malformation of the vestibular organ and the form of the scoliotic spine [6,8,[10][11][12]. Another study confirmed the influence of the pathology of the vestibular organ on scoliosis but questioned whether it had an impact on the formation or the progression of the curvature [8]. In three other studies, the relationship was not clearly verified; thus, further investigations were recommended [7,13,14].…”

“…Also, a dysfunction in the area of the brainstem favors the formation and progression of scoliosis [8,24]. In particular, if the vestibulospinal tract, whose function is to transmit position, balance reflexes, and control the axial muscles, is damaged unilaterally, an increased risk of developing scoliotic deformity is assumed.…”

“…Inhibited melatonin transfer (inhibition of the function of the inhibitory G proteins on the melatonin receptors) may also influence the development of scoliosis [4]. Interestingly, although controversial, a possible connection between the development of scoliosis and abnormalities in the vestibular organ may occur [5][6][7][8].…”

Impact of the Vestibular System on the Formation and Progression to Idiopathic Scoliosis: A Review of Literature

The physiopathogenesis of adolescent idiopathic scoliosis remains unknown. However, a multifactorial pathogenesis is being assumed. Besides biomechanical, biochemical, and genetic factors, some studies have focused on congenital or acquired abnormalities in the vestibular organ with consecutive development of scoliosis. This study aims to analyze a possible correlation between any vestibular organ congenital or acquired pathologies and scoliosis based on the current literature. Therefore, we conducted a literature search in three databases, with search terms such as “scoliosis,” “organ of balance,” “idiopathic scoliosis,” “vestibular organ,” “spine,” and “balance.” Fifteen studies were selected and used for research. The relationship between scoliosis and vestibular organ abnormalities was recorded from all included works. Seven studies demonstrated a direct correlation between vestibular organ anatomical abnormalities and the form of the scoliotic spine. Another study confirmed the influence of the pathology of the vestibular organ on scoliosis but questioned whether it had an impact on the formation or the progression of the curvature. Others demonstrated a temporal overlap of the embryonic development of the vestibular organ and the beginning of pre-scoliotic characteristics, but their relationship remained questionable. In three studies, the correlation remained unclear, and any context has been denied. It seems unlikely that an isolated vestibular disorder can trigger structural scoliosis. However, the vestibular system pathologies may certainly occur in the multifactorial genesis of idiopathic scoliosis. Whether the correlation refers to the expression or the progression of scoliosis or may even have an influence on both remains unclear. New treatment options could be derived from these findings with a positive influence on the course of the deformity.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional spine deformation with elusive aetiopathogenesis. One appealing hypothesis points to its neurologic origin with an emphasis on a vestibular impairment. In the present study, we explored the hypothesis of a vestibular deficit accompanying AIS by assessing differences in the subjective estimation of the gravitational vertical between adolescents with idiopathic scoliosis (n = 10, age 11-16 years, Cobb's angle > 15°) and healthy age-matched controls (n = 10). Group participants actively controlled the verticality of a visual line in two visual conditions (eyes open-visual feedback and eyes closed-no visual feedback) and using three different segments (hand, head, and trunk). An electromagnetic tracking sensor (Nest of Birds, Ascension Ltd., USA, 60 Hz), attached either to a hand-held rod, the head, or the upper trunk, measured the line's deviation from the gravitational vertical that was reflected in two measures, the mean absolute and variable error. The head's medio-lateral tilt when estimating verticality with the hand was also registered. Analysis revealed that adolescents with idiopathic scoliosis made a greater error than control participants when estimating verticality with the head and eyes closed. In addition, they adopted a significantly greater head tilt when estimating the vertical by controlling the hand-held rod, regardless of the availability of vision. The error in the earth vertical was greater when the estimate was performed in the absence of vision. Results suggest a malfunction of the vestibular system and/or a sensorimotor integration impairment in patients with AIS, while vision compensates for the observed deficit in estimating the earth vertical.
