BACKGROUND: Individuals with multiple sclerosis (MS) often have limited mobility that is thought to be due to the neuromuscular impairments of the ankle. Greater isometric motor control of the ankle has been associated with better standing postural balance but its relationship to mobility is less understood. The objectives of this investigation were to quantify the motor control of the ankle plantarflexors of individuals with MS during a dynamic isometric motor task, and explore the relationship between the ankle force control and gait alterations...

Robot-assisted surgery on a broad front - without evidence for being cost-effective Robot-assisted surgery is currently heavily marketed. The HTA centre in Region Västra Götaland has produced five HTA reports regarding use of robot-assisted surgery in different clinical situations (prostatic cancer, benign gynaecological surgery, pediatric pyeloplasty and fundoplication, and rectal cancer), finding weak evidence for a patient value. The current report by Per Carlsson et al confirms that robot-assisted surgery indeed leads to increased costs that are not balanced by augmented patient value, i...

Training quantification is basic to evaluate an endurance athlete's responses to the training loads, ensure adequate stress/recovery balance and determine the relationship between training and performance. Quantifying both external and internal workload is important, because the external workload does not measure the biological stress imposed by the exercise sessions. Generally used quantification methods include retrospective questionnaires, diaries, direct observation and physiological monitoring, often based on the measurement of oxygen uptake, heart rate and blood lactate concentration...

While it is well established that plants associating with arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) fungi cycle carbon (C) and nutrients in distinct ways, we have a limited understanding of whether varying abundance of ECM and AM plants in a stand can provide integrative proxies for key biogeochemical processes. We explored linkages between the relative abundance of AM and ECM trees and microbial functioning in three hardwood forests in southern Indiana, USA. Across each site's 'mycorrhizal gradient', we measured fungal biomass, fungal : bacterial (F : B) ratios, extracellular enzyme activities, soil carbon : nitrogen ratio, and soil pH over a growing season...

Ryo Watanabe, Hiroyuki Kajimoto
We have previously found that a vertical force or tactile sensation occurs when the temperature of a participant's skin changes rapidly. In this illusion, upward motion, pressure, or force sensation is elicited when stimulus temperature rises rapidly, whereas in the opposite case, downward motion or pulling sensation is elicited. In this paper, we applied this phenomenon to the sole (plantar surface of the foot) to present the sensation of ground slope. To investigate this, we conducted an experiment that measured the correlation between stimulation temperature and front-back direction position of the center of gravity...

: During standing balance, vestibular signals encode head movement and are transformed into coordinates that are relevant to maintaining upright posture of the whole body. This transformation must account for head-on-body orientation as well as the muscle actions generating the postural response. Here, we investigate whether this transformation is dependent upon a muscle's ability to stabilize the body along the direction of a vestibular disturbance. Subjects were braced on top of a robotic balance system that simulated the mechanics of standing while being exposed to an electrical vestibular stimulus that evoked a craniocentric vestibular error of head roll...

BACKGROUND: In treating patients with cervical myelopathy, surgical approach may be dictated by sagittal balance, highlighting the need for accurate pre-operative assessment. Magnetic Resonance Imaging (MRI) is widely-recognized for its utility in the diagnosis and surgical planning of cervical myelopathy. Plain radiographs (X-rays) are a reliable tool to assess bony alignment. However, they may not always be included in standard pre-operative evaluation, especially in an era of restricted payer-environments...

Negative pressure wound therapy (NPWT) is widely used to treat many types of complex wounds, and the advent of the instillation and dwell time (NPWTi-d) technique has enhanced this system with the addition of automated treatment with topical solutions. In the field of vascular surgery, NPWT is utilized to help close wounds over underlying grafts; however keeping these wounds free of infection and avoiding large reoperation when infection occurs remains a challenge. In this case report we present a patient who required acute intervention for limb ischemia, with a large wound created in the groin for anastomosis of a prosthetic graft bypass...

Paraplegic flexion contracture of hip joints beyond 90° is a difficult condition to treat for any orthopedic surgeon. There is no fixed protocol of treatment described, by and large it is individualized. A 20 year old female presented with paraplegia for last 15 years due to irrecoverable spinal cord disease with complete sensory and motor loss of both lower extremities and was admitted with acute flexion contracture of both hip joints with trunk resting on thighs. She underwent bilateral proximal femoral resection...

Aim of this study was to test the effects of a concurrent cognitive task on the promptness of the sensorimotor integration and reweighting processes following addition and withdrawal of vision. Fourteen subjects stood in tandem while vision was passively added and removed. Subjects performed a cognitive task, consisting of counting backwards in steps of three, or were 'mentally idle'. We estimated the time interval, following addition and following withdrawal of vision, at which body sway began to change. We also estimated the time constant of the exponential change in body oscillation until the new level of sway was reached, consistent with the current visual state...

BACKGROUND: People with chronic low back pain (CLBP) demonstrate greater postural instability compared with asymptomatic individuals. Rocker-sole shoes are inherently unstable and may serve as an effective balance training device. This study hypothesised that wearing rocker-sole shoes would result in long-term improvement in barefoot postural stability in people with CLBP. METHODS: 20 participants with CLBP were randomised to wear rocker-sole or flat-sole shoes for a minimum of 2 hours each day...

BACKGROUND: The ability of performing a balance or walking task in conjunction with a secondary cognitive or motor task, referred to as dual-task (DT) ability, is essential in daily living. While there is some evidence that DT performance is impaired in individuals with neurological conditions, using reliable and valid tools to measure DT performance is essential. This systematic review aimed to evaluate the psychometric properties of DT balance and walking assessments in individuals with different neurological conditions...

BACKGROUND AND PURPOSE: The development and implementation of effective interventions to prevent falls in older adults is a public health priority. The purpose of this study was to compare the efficacy of a new practice model, incorporating Shubert's evidence-based fall prevention recommendations, with the usual ambulatory physical therapy (PT) at Rusk Rehabilitation, to decrease fall risk among older adults living in the community. The hypotheses were (1) the proposed program would decrease participants' fall risk, (2) it would be more effective than our usual PT, and (3) the addition of 4 consults after discharge would improve compliance with a home exercise program...

Confined goats spend a substantial part of the day feeding. A poorly designed feeding place increases the risk of feeding in nonphysiological body postures, and even injury. Scientifically validated information on suitable dimensions of feeding places for loose-housed goats is almost absent from the literature. The aim of the present study was, therefore, to determine feeding place dimensions that would allow goats to feed in a species-appropriate, relaxed body posture. A total of 27 goats with a height at the withers of 62 to 80 cm were included in the study...

Plant transpiration is the main evaporative flux from terrestrial ecosystems; it controls land surface energy balance, determines catchment hydrological responses and influences regional and global climate. Transpiration regulation by plants is a key (and still not completely understood) process that underlies vegetation drought responses and land evaporative fluxes under global change scenarios. Thermometric methods of sap flow measurement have now been widely used to quantify whole-plant and stand transpiration in forests, shrublands and orchards around the world...
