“…Nevertheless, this type of analysis is useful for evaluating postural disturbances caused by specific diseases or conditions as it has been seen in previous studies. [18][19][20] In the test performed with EC, the SCI subjects demonstrated a significant increase in the contribution of the low-frequency band. Thus, the suppression of visual information may increment the dependency of vestibular information.…”

Study Design: Cross-sectional, observational study of paraplegic and able-bodied persons. Objectives: The aim of the study was to analyse the temporal and frequency domains of seated balance to better understand nervous system control in equilibrium in persons with spinal cord injury (SCI) and to explore their centre of pressure (CoP) limits before experiencing a fall. Setting: University of Valencia, Spain. Methods: Static and dynamic seated balance were assessed in 24 paraplegic persons divided into two groups: low paraplegia group (LP) and high paraplegia group (HP), and 24 healthy volunteers with an extensiometric force plate. Two types of tests were performed: a static test (ST), where data signal was analysed by temporal and frequency domains, and a stability limit test (SLT), where different stability limits were calculated. Results: The paraplegic group revealed lower static postural control in both domains in most of the parameters analysed compared with the control group (CG). Similar results were obtained with regard to the SLT, showing differences in the three parameters analysed between the CG and SCI groups. Conclusion: Posturographic assessment in ST was useful to explore nervous system control in equilibrium in this population, presenting a decreased balance in paraplegic groups and an altered pattern in the sensorial and cerebellum bands compared with able-bodied individuals. Furthermore, SLT indicated less movement control of the CoP in paraplegic groups, which may influence the performance of their daily activities.

“…Research on controlling the balance conducted by other authors suggests that people with DS have problems with normal body balance control [11,12]. Cabeza-Ruiz et al [1] have reported, on the basis of studies, that people with DS have a weaker body balance control than their peers and have a greater postural sway than healthy individuals [11,13,14]. Researchers on the body balance control believe that individuals with DS use a different pattern of muscle tension while standing than healthy people do in order to maintain balance in a standing position [15].…”

“…Physiotherapists find it particularly difficulty when they encounter intellectually disabled person with whom communication is limited. Experimental results of tests, conducted by Cabeza-Ruiz et jakie przeprowadzili Cabeza-Ruiz i wsp., dowodzą, że osoby z zespołem Downa (Down syndrome -DS) potrzebują interwencji terapeutycznej w każdym wieku do poprawy swojej ogólnej sprawności fizycznej [1].…”

“…Cabeza-Ruiz i wsp. [1] na podstawie badań donoszą, że osoby z DS wykazują słabszą kontrolę równowagi ciała niż rówieśnicy i charakteryzują się większym kołysa-niem postawy niż osoby zdrowe [11,13,14]. Badacze kontroli równowagi ciała uważają, że osoby z DS wykorzystują inny wzorzec napięcia mięśni podczas stania, niż czynią to osoby zdrowe w celu zachowania równowagi w pozycji stojącej [15].…”

Cel pracy: Celem pracy było sprawdzenie, czy 5-miesięczny trening z zastosowaniem specyficznych ćwiczeń równo-ważnych według programu autorskiego poprawia kontrolę równowagi ciała u dzieci z zespołem Downa (DS). Materiał i metody: W badaniach wzięło udział 8 osób z DS -4 płci męskiej i 4 płci żeńskiej -w wieku 13-24 lat. Badani wykonywali dwukrotnie -jedną po drugiej -20-sekundową próbę stania w naturalnej pozycji stojącej na dwóch platformach sił typu AccuSway (AMTI), po jednej pod każdą kończyną dolną. Na podstawie przebiegu punktu nacisku stóp COP (center of pressure) w funkcji czasu obliczono wskaźniki równowagi ciała: zakres, zmienność, prędkość i pole powierzchni przesunięć punktu COP. Badania przeprowadzono w dwóch sesjach: przed rozpoczęciem 5-miesięcznego specyficznego treningu równowagi ciała według programu autorskiego i po jego zakończeniu. Wyniki: Wyniki badań wykazały obniżenie się wartości wskaźnika prędkości COP prawej kończyny dolnej oraz zakresu COP w kierunku przednio-tylnym obu kończyn dolnych w 2. sesji badań w stosunku do 1. sesji. Wnioski: Stwierdzono, że kontrola równowagi ciała poprawiła się po 5-miesięcznym specyficznym treningu w porównaniu ze stanem wyjściowym, a autorski program może być stosowany w terapii dzieci i młodzieży z zespołem Downa. Słowa kluczowe: równowaga ciała, zespół Downa, autorski program ćwiczeńAbstract: Aim of the study: The aim of this study was to verify whether the 5-month training exercises using specific balance exercises of the authorial program improves body balance control in children with Down syndrome (DS). Materials and methods:The purpose of this study was the verification if the 5-months posture control exercises training by original program relays to posture control in Down syndrome (DS) children and youth. The subjects were 8 DS persons: 4 males and 4 females, aged 13-24. Two 20-seconds consecutive trails of natural bipedal standing position on 2 force platforms AccuSway (AMTI), one under each foot, were performed during research. On the basis of COP (centre of pressure) time series the following indices were computed: range, variability, velocity and area of COP shifts. There were 2 sessions of the research: one just before and the second just after 5-month lasting specific posture control training based on the original exercise program. Results:The results revealed decreasing of the COP velocity of right lower limb and the COP range in anteriorposterior direction of both lower limbs after the training, comparing to the values from the first research session. Conclusions: It is concluded that the specific posture control training by the presenting of the original exercises program influenced the posture control improving it and the program can be used in therapy of DS children and youth.

This article introduces a flexible nonparametric approach for analyzing the association between covariates and power spectra of multivariate time series observed across multiple subjects, which we refer to as multivariate conditional adaptive Bayesian power spectrum analysis (MultiCABS). The proposed procedure adaptively collects time series with similar covariate values into an unknown number of groups and nonparametrically estimates group‐specific power spectra through penalized splines. A fully Bayesian framework is developed in which the number of groups and the covariate partition defining the groups are random and fit using Markov chain Monte Carlo techniques. MultiCABS offers accurate estimation and inference on power spectra of multivariate time series with both smooth and abrupt dynamics across covariate by averaging over the distribution of covariate partitions. Performance of the proposed method compared with existing methods is evaluated in simulation studies. The proposed methodology is used to analyze the association between fear of falling and power spectra of center‐of‐pressure trajectories of postural control while standing in people with Parkinson's disease.
