Beyond the classical paradigm that presents the Anticipatory Postural Adjustments (APAs) as a manner to create forces that counteract disturbances arising from the moving segment during a pointing task, there is a controversial discussion about the role APAs to facilitate the movement and perform a task accurately. In addition, arm kinematics features are classically used to infer the content of motor planning for the execution and the control of arm movements. The present study aimed to disentangle the conflicting role of APAs during an arm-pointing task in which the subjects reach a central diode that suddenly turns on, while their postural stability was manipulated. Three postures were a…
Effects of physiotherapy interventions on balance in multiple sclerosis: A systematic review and meta-analysis of randomized controlled trials
2012
Objective: to determine the effects of physiotherapy inter ventions on balance in people with multiple sclerosis. Data sources: A systematic literature search was conducted in Medline, cinahl, embase, PeDro, both electronically and by manual search up to March 2011. Study selection: Randomized controlled trials of physiothe rapy interventions in people with multiple sclerosis, with an outcome measure linked to the International Classifica tion of Functioning, Disability and Health (icF) category of “changing and maintaining body position”, were included. Data extraction: the quality of studies was determined by the van tulder criteria. Metaanalyses were performed in subgroups according…
„Phobischer Schwankschwindel”
1997
Due to the results of an interdisciplinary study on patients with vertigo as the chief symptom and on the background of psychodynamic theories concerning anxiety disorders the term of phobic postural vertigo (Brandt & Dieterich 1986) is discussed. It becomes obvious that phobic postural vertigo is a generalizing term which encompasses different forms of psychogenic vertigo. The authors plead for a more differentiated diagnosis and subgroup oriented classification of vertigo caused by psychiatric disorders.
Ankle muscle strength discriminates fallers from non-fallers
2014
International audience; It is well known that center of pressure (CoP) displacement correlates negatively with the maximal isometric torque (MIT) of ankle muscles. This relationship has never been investigated in elderly fallers (EF). The purpose of this study was thus to analyze the relationship between the MIT of ankle muscles and CoP displacement in upright stance in a sample aged between 18 and 90 years old that included EF . The aim was to identify a threshold of torque below which balance is compromised. The MIT of Plantar flexors (PFs) and dorsal flexors (DFs) and CoP were measured in 90 volunteers: 21 healthy young adults (YA) (age: 24.1 +/- 5.0), 12 healthy middle-aged adults (MAA)…
Musculoskeletal examination in young athletes and non-athletes:the Finnish Health Promoting Sports Club (FHPSC) study
2018
ObjectivesTo determine the inter-rater repeatability of a musculoskeletal examination and to compare findings between adolescent athletes and non-athletes in Finland.MethodsIn this cross-sectional study, a musculoskeletal examination assessing posture, mobility and movement control was carried out by a sports and exercise medicine physician on 399 athletes aged 14–17 years and 177 non-athletes. Within 2 weeks another sports and exercise medicine physician repeated the examination for 41 adolescents to test the inter-rater repeatability.ResultsIn total, 10 of the 11 tests performed had at least moderate inter-rater reliability (κ ≥0.4 or percentage agreement >80%). Athletes more often tha…
Investigating cardiovascular and cerebrovascular variability in postural syncope by means of extended Granger causality
2014
The patterns of Granger causality (GC) between heart period (HP), mean arterial pressure (AP) and cerebral blood flow velocity (FV) were investigated in ten subjects with postural related syncope (PRS). The classic GC measure based on vector autoregressive (VAR) modeling was compared with a novel extended GC (eGC) measure derived from VAR models incorporating instantaneous causal effects among the series. The analysis was performed in the supine and in the upright position during early (ET) and late (LT, close to presyncope) epochs of head-up tilt. Moving from ET to LT, both GC and eGC decreased from AP to HP, and increased from AP to FV, reflecting baroreflex impairment and loss of cerebra…
Methods and Strategies for Reconditioning Motor Output and Postural Balance in Frail Older Subjects Prone to Falls
2021
In frail older subjects, the motor output of the antigravity muscles is fundamental in resisting falls. These muscles undergo accelerated involutions when they are inactive and the risk of falling increases during leisure and domestic physical activity. In order to reduce their risk of falling, frail older subjects limit their physical activities/exercises. The problem is that the less they exercise, the less they are able to exercise and the greater the risk in exercising. Hence, a vicious circle sets up and the antigravity muscles inevitably continue to deteriorate. This vicious circle must be broken by starting a reconditioning program based on developing the strength of antigravity musc…
Postural Adaptations in Preadolescent Karate Athletes Due to a One Week Karate Training Camp
2013
Abstract The aim of this study was to investigate the effect of an increasing number of training hours of specific highintensity karate training on postural sway in preadolescent karate athletes. Seventy-four karatekas were randomly assigned to 1 of 2 groups: Karate Group (KG=37): age 10.29±1.68 yrs; or Control Group (CG= 37): age 10.06±1.77 yrs. The KG performed two sessions per day for 1 week in total, while the CG performed only 3 sessions during the same period. The center-of-pressure length (COPL) and velocity (COPV) were recorded under four different experimental conditions: open eyes (EO), closed eyes (EC), open eyes monopodalic left (EOL), open eyes monopodalic right (EOR), pre as w…
Improved Postural Control after Behavioural Short Term Intervention in Patients with Psychiatric Dizziness
2009
Background:Patients with psychiatric dizziness often report subjective instability of stance and gait and fear of falls. They showed increased activity of their body sway in static posturography compared to normals (1, 2). Aim of the present study was to evaluate the efficiency of a behavioural therapy by static posturography.Methods:14 patients with psychiatric dizziness were included in the prospective study on static posturography to quantify the postural sway (sway path) during upright stance under different conditions. the psychosomatic examination comprised of standardized interviews (SCID-Interview) and a psychometric examination battery (SCL-90, VSS, VHQ). Results of static posturog…
The proprioceptive insole: A therapeutic aid for the diabetic patient in prevention?
2021
The diabetic foot represents one of the most common complications among patients with type 2 diabetes mellitus. Prevention of the diabetic foot is therefore essential both to ensure the patient a better quality of life and to reduce the costs borne by the NHS and this requires a multidisciplinary approach. It is important to underline that the major complications of the diabetic foot are due to biomechanical, vascular and neuropathic alterations. Diabetic patients are less likely to perform physical exercises and tend to walk less, adopting compensatory strategies based on the type of terrain they find. They walk slower, tend to take shorter steps with a wider base of support, have limited …
