OBJECTIVE: To compare the relationship between postural control and knee and hip osteoarthritis in older adults with and without a history of falls. METHODS: Fallers were those with ≥ 2 falls or 1 injurious fall over 12 months. Non-fallers were volunteers with no falls in the past year. Radiological evidence of osteoarthritis with no reported symptoms was considered "asymptomatic osteoarthritis", while "symptomatic osteoarthritis" was defined as radiographic osteoarthritis with pain or stiffness...

Single steps in different directions are often used for postural corrections. However, our knowledge about the neural mechanisms underlying their generation is scarce. This study was aimed to characterize the corrective steps generated in response to disturbances of the basic body configuration caused by forward, backward or outward displacement of the hindlimb, as well as to reveal location in the CNS of the corrective step generating mechanisms. Video recording of the motor response to translation of the supporting surface under the hindlimb along with contact forces and activity of back and limb muscles was performed in freely standing intact and in fixed postmammillary rabbits...

BACKGROUND: The Ehlers-Danlos Syndrome (EDS) is a rare disorder affecting the connective tissue. EDS patients may suffer of proprioception and balance impairment but all the studies dealing with such symptoms have been addressed to adult subjects. The Study of such impairment in younger patients may lead to a better awareness of own motor abilities and to a focused rehabilitative intervention. Therefore, our work aims to assess the occurrence of these alterations in a pediatric cohort of EDS patients...

Harald Hefter, Dietmar Rosenthal
BACKGROUND: It has been hypothesized that altered trunk movements during gait in post-stroke patients or children with cerebral palsy are compensatory to lower limb impairment. Improvement of trunk movements and posture after injections of botulinum toxin into the affected arm would be at variance with this hypothesis and hint towards a multifactorial trunk control deficit. PATIENTS AND METHODS: Clinical gait analysis was performed in 11 consecutively recruited hemiplegic patients immediately before and 4weeks after a botulinum toxin type A-injection into the affected arm...

Numerous techniques have been used to minimize error in relating the surface electromyogram (EMG) to elbow joint torque. We compare the use of three techniques to further reduce error. First, most EMG-torque models only use estimates of EMG standard deviation as inputs. We studied the additional features of average waveform length, slope sign change rate and zero crossing rate. Second, multiple channels of EMG from the biceps, and separately from the triceps, have been combined to produce two low-variance model inputs...

New insight regarding limb-dominance effects on temporal-spatial gait parameters is needed to further investigate subjects with recurrent low back pain (LBP). Although an asymmetrical gait pattern was found to reflect natural functional differences, there is a lack of information regarding gender differences on dominant limb support patterns in subjects with LBP. The purpose of this study was to investigate temporal-spatial gait parameters based on limb dominance and gender between subjects with and without LBP...

The aim of this study was to investigate associations between poor spinal posture and the recurrence of major depressive episodes and severity of symptoms in patients with major depressive disorder (MDD). This was a cross-sectional quantitative study of MDD patients. Outpatients were recruited from consecutive admissions at a mood disorders unit of a tertiary psychiatric hospital. Of 136 MDD patients, 72 (53 women, 19 men; mean age, 42.4±9.1years) met all the criteria and completed the study. Forty-one patients were classified with a recurrent episode (RE) of MDD and 31 with a single episode (SE)...

BACKGROUND: Increased postural sway has been repeatedly documented in children with autism spectrum disorder (ASD). Characterizing the control processes underlying this deficit, including postural orientation and equilibrium, may provide key insights into neurophysiological mechanisms associated with ASD. Postural orientation refers to children's ability to actively align their trunk and head with respect to their base of support, while postural equilibrium is an active process whereby children coordinate ankle dorsi-/plantar-flexion and hip abduction/adduction movements to stabilize their upper body...

INTRODUCTION: Alterations in the musculoskeletal system, especially in the lower limbs, limit physical activity and affect balance and walking. Postural impairments in haemophilic preteens could increase the risk of bleeding events and deteriorate the physical condition, promoting the progression of haemophilic arthropathy. AIM: This study aims to evaluate static postural balance in haemophilic children, assessed by means of the Wii Balance Board(®) (WBB). METHODS: Nineteen children with haemophilia and 19 without haemophilia aged 9-10 years, have participated in this study...

PURPOSE: Orthodontists influence dental occlusion directly. To suggest any link between dental occlusion and body posture is highly contentious, as evidenced by the literature. Rasterstereography, an optical technique that enables three-dimensional (3D) body measurements to be collected, has not yet been used to impartially examine whether different occlusal positions could instantaneously alter spine and body posture. We therefore set out to use this technique to nonsubjectively evaluate this question under static conditions...

It remains unclear which specific brain regions are the most critical for human postural control and balance, and whether they mediate the effect of age. Here, associations between postural performance and corticosubcortical brain regions were examined in young and older adults using multiple structural imaging and linear mixed models. Results showed that of the regions involved in posture, the brainstem was the strongest predictor of postural control and balance: lower brainstem volume predicted larger center of pressure deviation and higher odds of balance loss...
