“…Our study also compared the stabilometric parameters among the above mentioned dental conditions. Previous studies assessed the reliability of stabilometric analysis using a force platform and showed good intra-and intersession reliability [25,26]. Path length is considered to be a valid outcome measurement in numerous balance conditions; the smaller the path length, the better is the postural stability [27].…”

BackgroundPosture is influenced by many factors and dental occlusion seems to have its role on postural stabilization. Our rationale to perform the study was to find out if there are differences of static plantar pressure and stabilometric parameters depending on different dental conditions. MethodsThe observational study consisted in plantar pressure assessment and stabilometric analysis of 95 right-handed healthy volunteer subjects (mean age 22.94 ± 2.52 years) by using the PoData system. Each subject followed four measurements with open eyes: mandibular postural position, maximum intercuspation, biting on cotton rolls and maximum mouth opening. Plantar pressure was recorded on 1 st and 5 th metatarsal heads and heel, and was expressed as percentage of weight distribution on each foot. The recorded centre of pressure (CoP) parameters were: CoP path length, 90%confidence ellipse area and maximum CoP speed. Statistical analysis used repeated-measures ANOVA with Bonferroni posthoc analysis and Friedman test.

“…From a biomechanical point of view the measurement of the centre of pressure (CoP) displacement by means of force platforms is the most employed system to evaluate static upright posture. This methodology of postural assessment proved good intra-session and inter-session reliability, above all referred to sway length, CoP X and CoP Y parameters [ 2 ]. In addition to standard postural sway parameters, Collins and De Luca [ 3 ] introduced the stabilogram diffusion analysis (SDA) demonstrating that in a static upright posture, CoP trajectories could be modelled as a fractional Brownian motion and that two different neuro muscular control mechanisms operated: open-loop control schemes over short term intervals and closed loop control schemes over long-term intervals.…”

Static and Dynamic Postural Changes after a Mountain Ultra-Marathon of 80 km and 5500 D+

The study aimed to investigate the effect of fatigue on static and dynamic postural stability after completing a mountain ultra-marathon. Twelve male athletes participated in the study. Postural stability was assessed before and immediately after the race. Static postural stability was evaluated on a dynamometric platform with eyes opened (OE) and closed (CE). Dynamic postural stability was assessed with OE on an instrumented plate which allowed medio-lateral oscillations. Stabilometric data were affected by fatigue in the OE condition, concerning sway path velocity (p = 0.0006), sway area velocity (p = 0.0006), area of the confidence ellipse (p = 0.0016), maximal anterior-posterior (AP) (p = 0.0017) and medio-lateral (ML) (p = 0.0039) oscillations. In the CE condition the sway path velocity (p = 0.0334), the maximal ML oscillations (p = 0.0161) and the area of the confident ellipse (p = 0.0180) were also negatively influenced. Stabilogram diffusion analysis showed in the OE condition an increase of short-term diffusion coefficients considering the anterior-posterior direction (Dfys; p = 0.0023) and the combination of the two (Dfr2s; p = 0.0032). Equally, long term diffusion coefficients increased considering the anterior-posterior direction (Dfyl; p = 0.0093) and the combination of the two (Dfr2l; p = 0.0086). In CE condition greater values were detected for medio-lateral direction (Dfxl; p = 0.033), anterior-posterior direction (Dfyl; p = 0.0459) and the combination of the two (Dfr2l; p = 0.0048). The dynamic postural stability test showed an increase of the time spent with the edges of the plate on the floor (p = 0.0152). Our results showed that mountain ultra-marathon altered static stability more than dynamic stability. An involvement of cognitive resources to monitor postural stability after fatiguing could be the explanation of the worsening in the automatic task (quiet standing) and of the positive compensation in the less automatic task (dynamic standing on the instrumented plate).

Background: Symmetrical dental occlusion blocking (bicuspid region) is used in dentistry as a quick diagnostic test (“Meersseman test”) to check a possible influence of the temporomandibular system (TMS) on the movement system. Immediate effects between occlusal blocking and rest position on body sway and weight distribution in general and for both genders and for four age decades should be evaluated.Methods: 725 (396f/329m) healthy subjects (neither subjective signs of TMD nor acute/chronic complaints in the musculoskeletal system) volunteered (21 to 60 years) while both genders were divided into four age groups according to decades. A pressure measuring platform was used. The postural control (body sway and weight distribution) was recorded in two dental occlusion conditions (a) in rest position and (b) symmetrical blocking (bicuspid region) by cotton rolls. Results: The frontal sway reduced by 0.67mm (t(724) = -3.9 (p < 0.001)) and the sagittal sway by 0.33mm (t(724) = -3.4 (p < 0.001)). The relative pressure under the forefoot left increased by 0.33% (t(724) = 2.88 (p < 0.001)) and the relative pressure overall under the forefoot increased by 0.67% (t(724) = -3.4 (p < 0.001)). Gender-specific and age-specific reactions cannot be recorded.Discussion: In all subjects the postural sway improved slightly when blocking the occlusion ("Meersseman test") compared to the rest position. There is a slight shift of weight on the forefoot, especially the left forefoot. There exist no age- and gender-specific differences. Clinically relevant differences should apply outside the data between the 1st and 3rd quantile.
