This study systematically explored the potential of applying feedback control of functional neuromuscular stimulation (FNS) for stabilizing various erect and leaning standing postures after spinal cord injury (SCI). Perturbations ranging from 2 to 6% body weight were applied to two subjects with motor complete thoracic level SCI who were proficient at standing with implanted multichannel neural stimulators to activate the ankle, knee, hip and trunk muscles. The subjects stood with four different postures: erect, forward, forward-right and forward-left...

In order to address the accuracy of the long-standing experimental enthalpy of formation of gas-phase hydrazine, fully confirmed in earlier versions of Active Thermochemical Tables (ATcT), the provenance of that value is re-examined in light of new high-end calculations of the Feller-Peterson-Dixon (FPD) variety. An overly optimistic determination of the vaporization enthalpy of hydrazine, which created an unrealistically strong connection between the gas phase thermochemistry and the calorimetric results defining the thermochemistry of liquid hydrazine was identified as the probable culprit...

The purpose of this study was to compare the effects of different ankle and knee supports on balance in early ambulation of post-stroke hemiplegic patients. This is a randomized experimental study. The study sample included 20 hemiplegic patients who were able to stand with support and who had been diagnosed with a cerebrovascular accident within the last month. A knee immobilization brace (KIB) was first placed on each individual (first application), followed by placement of knee immobilizer brace and Foot Lifter Orthosis ® (FLO) (second application), and lastly, placement of KIB and rigid taping (RT) (third application)...

Spatial variation in cone serotiny in Rocky Mountain lodgepole pine (Pinus contorta ssp. latifolia) across Yellowstone National Park influences initial pine recruitment after stand-replacing fire with tremendous population, community, and ecosystem consequences. A previous study showed that much of the spatial variation in serotiny results from the balance of selection arising from high frequencies of fire favoring serotiny countered by opposing selection exerted by American red squirrels (Tamiasciurus hudsonicus) as seed predators...

BACKGROUND: Balance deficits in multiple sclerosis (MS) are often monitored by means of observer-rated tests. These may provide reliable data, but may also be time-consuming, subject to inter-rater variability, and potentially insensitive to mild fluctuations throughout the clinical course. On the other hand, laboratory assessments are often not available. The Nintendo Wii Balance Board (WBB) may represent a low-cost solution. The purpose of the current study was to examine the methodological quality of WBB data in MS (internal consistency, test-retest reliability), convergent validity with observer-rated tests (Berg Balance Scale, BBS; Timed-Up and Go Test, TUG), and discriminative validity concerning clinical status (Expanded Disability Status Scale, EDSS)...

BACKGROUND: Trunk control impairment often accompanies multiple sclerosis (MS). Trunk stability is necessary for movements of extremities, as are selective trunk movements for normal gait. Measuring trunk function is thus of interest. METHODS: We examined the relationships between the Trunk Impairment Scale (TIS1.0 and TIS2.0) and the Berg Balance Scale (BBS), 5 sit-to-stand test (5STS), Timed Up and Go test (TUG), 10-m timed walk test (10TW), 2-min walk test (2MWT), Falls Efficacy Scale - International, and 12-item MS Walking Scale (MSWS-12) in 47 outpatients...

Understanding which aspects of vision are related to falls is important. We examine the associations between tests of balance, mobility, fear of falling (FES-1) and aspects of vision in 72 adults aged 70+. Balance and mobility were examined using the One Legged Stance test (OLST), the Sit to Stand test (STST) and the 5 Meter Walking test (5MWT). Visual measures included visual acuity (VA), contrast sensitivity, stereoacuity, binocular vision (BV) measurements, Useful field of View (UFV) and Attended Field of View (AFOV)...

Prediction models for post-kidney transplant (KT) mortality have had limited success (C-statistics≤0.70). Adding objective measures of potentially modifiable factors may improve prediction and, consequently, KT survival through intervention. The short physical performance battery (SPPB) is an easily administered objective test of lower extremity function consisting of three parts (balance, walking speed, chair stands), each with scores of 0-4, for a composite score of 0-12, with higher scores indicating better function...

BACKGROUND CONTEXT: Global balance of human standing is analyzed as the geometric sum of the individual alignments extending from the spinal column to the pelvis, and to the lower limbs. The innovative EOS system has opened new perspectives for the global analysis of whole body alignment, but its use is very limited due to its high cost. An alternative may be to combine the whole spine lateral radiograph and the lateral scanogram in the global sagittal analysis of whole body alignment...

Blood flow restriction (BFR) in combination with exercise has been used to increase muscle size and strength using relatively low loads (20%-30% 1RM). In research, the range of applied pressures based on a percentage of arterial occlusion pressure (AOP), is wide. PURPOSE: To measure the blood flow response before, following each set of exercise, and post exercise to low-load elbow flexion combined with no restriction (NOBFR), 40% of AOP (40BFR), and 80% of AOP (80BFR). METHODS: 152 participants volunteered; 140 completed the protocol (women=75, men=65)...

The aims of this study were to identify static and dynamic balance with the addition of weighted vests for the rehabilitation of paraplegic patients. The study was conducted using weighted vest exercises with applied optimal weight ratios. Ten paraplegic patients who use custom orthosis were enrolled for experiments including static standing and dynamic gait with a weighted vest. We set weight ratios as 0%, 10%, and 15% of the patients' weight. A plantar pressure device was used for static balance tests for excursion and velocity of center of pressure and we identified dynamic balance through the tool of Timed Up and Go (TUG) test...

BACKGROUND: Information received subconsciously can influence exercise performance; however, it remains unclear whether subliminal or supraliminal reward is more effective in improving standing balance ability when priming stimuli are subconsciously delivered. The present study aimed to compare the effects of subliminal priming-plus-subliminal reward stimuli (experimental) with subliminal priming-plus-supraliminal reward stimuli (control) on standing balance ability. METHODS: This was a single-blind (outcome assessor), parallel-group, randomized controlled trial involving healthy young adults recruited from a university in Japan...

Systemic lupus erythematosus (SLE) is a highly unpredictable and potentially lethal disease which ultimately challenges identity, future and the meaning of life. In a caring context, the experience of good health is perceived to be a balance between biomedical health and the existential experience of having a good life. This balance is jeopardised in the face of severe chronic illness and leads to extensive suffering if not handled carefully. Research suggests that patients suffering from severe chronic illness need support on an existential level, but also emphasises that, given its elusive nature, caring for the existential dimension is difficult to manage...

Introduction Childhood immunisation against seasonal influenza promises to reduce the burden of disease through herd immunity. The option of intranasal vaccination seemed to offer a more acceptable vaccination for children, as they are perceived to be less invasive. Yet, intranasal vaccines have been recently proven not to be as effective as presumed. In Germany, contradictory recommendations of the Standing Committee on Vaccination (STIKO) first, to use and then, in October 2016, not use these vaccines have been issued for the 2016-2017 season, whereas recommendations not to use them were already issued in the USA (CDC, ACIP)...

Postural control after applying perturbation involves neural and muscular efforts to limit the center of mass (CoM) motion. Linear dynamical approaches may not unveil all complexities of body efforts. This study was aimed at determining two nonlinear dynamics parameters (fractal dimension (FD) and largest Lyapunov exponent (LLE)) in addition to the linear standing metrics of balance in perturbed stance. Sixteen healthy young males were subjected to sudden rotations of the standing platform. The vision and cognition during the standing were also interfered...

BACKGROUND: Despite the evidence for improved safety and function of microprocessor stance and swing-controlled prosthetic knees, non-microprocessor-controlled prosthetic knees are still standard of care for persons with transfemoral amputations in most countries. Limited feature microprocessor-control enhancement of such knees could stand to significantly improve patient outcomes. OBJECTIVES: To evaluate gait speed, balance, and fall reduction benefits of the new 3E80 default stance hydraulic knee compared to standard non-microprocessor-controlled prosthetic knees...
