The aim of the study was to evaluate the effect of surgical reconstruction of anterior cruciate ligament (ACL) on postural stability and responses to lower limb (LL) muscles vibrations. Centre of pressure (CoP) was measured in 17 subjects during stance on firm/foam surface with eyes open/closed and during unilateral vibrations of LL muscles (m. triceps surae - TS, m. quadriceps femoris - Q, m. quadriceps femoris and hamstrings simultaneously - QH). The measurements were performed: 1) preoperatively, 2) six weeks and 3) three months after the reconstruction...

Balance impairment is common in people with multiple sclerosis (PwMS) and frequently impacts quality of life by decreasing mobility and increasing the risk of falling. However, there are only scarce data examining the contribution of specific neurological functional systems on balance measures in MS. Therefore, the primary aim of our study was to examine the differences in posturography parameters and fall incidence according to the pyramidal, cerebellar and sensory systems functional systems in PwMS. The study included 342 PwMS, 211 women and mean disease duration of 8...

Posturography is used to assess balance in clinical settings, but its relationship to gait stability is unclear. We assessed if dynamic gait stability is associated with standing balance in 12 patients with unilateral vestibulopathy. Participants were unexpectedly tripped during treadmill walking and the change in the margin of stability (MoSchange) and base of support (BoSchange) relative to non-perturbed walking was calculated for the perturbed and first recovery steps. The centre of pressure (COP) path during 30s stance with eyes open and closed, and the distance between the most anterior point of the COP and the anterior BoS boundary during forward leaning (ADist) were assessed using a force plate...

OBJECTIVE: To examine the relationship between white matter changes (WMCs) and abnormal balance test results on computerized dynamic posturography (CDP) and electronystagmography (ENG). Also, to compare the utility of CDP with ENG for this purpose. STUDY DESIGN: Retrospective case review. SETTING: Tertiary care referral center. PATIENTS: A retrospective review of 137 subjects was conducted. The CDP and ENG results were compared between patients with (80) and without (57) WMCs as detected byT2/fluid attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI)...

OBJECTIVE: Impaired balance in patients with Parkinson's disease (PD) leads to loss of balance and frequent falls. Computerized dynamic posturography allows the assessment of stance tasks whereas mobile posturography analyzes the balance in free-field conditions, where falls among PD patients commonly occur (e.g. sitting down or standing up). The aim of the present study is to assess postural stability in PD patients with both techniques. STUDY DESIGN: Prospective study...

OBJECTIVE: Dizziness is a common complaint in patients following mild head or neck trauma, but neurological signs are usually rare or absent. The aim of the study was to compare postural control in patients with different types of head and neck trauma to healthy subjects. METHODS: Balance function was evaluated by computerized dynamic platform posturography (CDPP) in 57 dizzy patients with whiplash injury (n = 11), mild head trauma without loss of consciousness (HTNLC) (n = 23), whiplash injury and mild head trauma without loss of consciousness (WHTNLC) (n = 12) and mild head trauma with loss of consciousness (n = 11) and in 14 healthy subjects...

PURPOSE: This study aims to evaluate the posture and body balance of students with and without oral breathing, as well as to verify whether there is a correlation between the values obtained in this evaluation and those of the analysis of sensory systems. METHODS: The research was conducted with school children aged 8 to 12 years. The sample was subdivided into two study groups: schoolchildren with oral breathing and school children without oral breathing (control)...

We investigated whether vestibular dysfunction may cause or contribute to postural imbalance and falls in patients with Niemann-Pick type C disease (NP-C). Eight patients with NP-C disease and 20 healthy controls were examined using the video-based head impulse test (vHIT) and caloric irrigation to investigate horizontal canal function as well as ocular- and cervical vestibular evoked myogenic potentials (o- and cVEMP), and binocular subjective visual vertical estimation (SVV) for otolith function, and static posturography...

OBJECTIVE: To investigate which concurrent cognitive task (if any) had the most detrimental effect on balance control of patients with multiple sclerosis (MS). METHODS: In a dual-task experiment, we evaluated the reciprocal effect of simultaneously performing a postural and a cognitive task on balance and cognition in 52 patients and 26 sex- and age-matched controls. Balance was assessed by static posturography, while cognition was scored as number of correct items at 3 different neuropsychological tests, i...

BACKGROUND AND AIM: Static posturography can serve as an easy and fast way to determine whether a child possesses sufficient balance control in different sensory conditions. Therefore, the aim of this review is to map age-related differences in postural sway during childhood in typically developing children, using static posturography and to provide an overview of the available (age-specific) reference values in scientific literature. METHODS: The search strategy was performed in five databases (Pubmed, Web of Science, ScienceDirect, Cochrane Clinical Trials, Medline (Ovid)) November 2nd 2014 and updated twice: March 16th 2015 and July 20th 2015...

BACKGROUND: Patients with end-stage renal disease (ESRD) have increased risk of falls and fall-related complications. Other than aging and factors related to chronic kidney disease, treatment of hemodialysis may also contribute to this increased risk. The aim of this study was to demonstrate the impairment of balance after a session of hemodialysis with a quantitative assessment and reveal an increased fall risk that would possibly be related to treatment of hemodialysis for patients on maintenance hemodialysis...

Age-related changes in the density, morphology, and physiology of plantar cutaneous receptors negatively impact the quality and quantity of balance-relevant information arising from the foot soles. Plantar perceptual sensitivity declines with age and may predict postural instability; however, alteration in lower limb cutaneous reflex strength may also explain greater instability in older adults and has yet to be investigated. We replicated the age-related decline in sensitivity by assessing monofilament and vibrotactile (30 and 250 Hz) detection thresholds near the first metatarsal head bilaterally in healthy young and older adults...

BACKGROUND: Cervicogenic dizziness is a musculoskeletal disorder mainly characterised by dizziness and disequilibrium associated with neck pain. The pathophysiology is unclear and the neurophysiological basis remains to be ascertained. The aim of this study is to compare the vestibulo-ocular reflex and postural control between patients with cervicogenic dizziness and asymptomatic subjects, and to assess the association between debilitating dizziness and other psychosocial variables. MATERIALS AND METHODS: A total of 20 patients and 22 asymptomatic subjects were selected...

Poor seated balance negatively impacts the performance of activities of daily living in nonambulatory individuals with multiple sclerosis (MS) and is frequently a target of rehabilitation interventions. However, there is a lack of clinical measures of seated balance in nonambulatory individuals with MS, thus limiting evaluation of rehabilitation treatments. The aim of this investigation is to determine the reliability and concurrent validity of the Function in Sitting Test (FIST) as a measure of sitting balance in nonambulatory individuals with MS...
