#1
Erik C Prinsen, Marc J Nederhand, Bart F Koopman, Johan S Rietman
The added value of user-adaptive prosthetic knees has been predominantly evaluated in level walking or ramp/stair negotiation. Previous studies indicate that the activity pattern of individuals with an amputation mainly consists of short periods of continuous walking, indicating that a high percentage of ambulatory activity involves gait termination. The potential added value of user-adaptive prosthetic knees in gait termination has not been studied yet. Ten individuals with an amputation were measured with their own non-microprocessor controlled prosthetic knee and with the Rheo Knee II (a user-adaptive prosthetic knee)...

The Supernumerary robotic limbs are a recently introduced class of wearable robots that, differently from traditional prostheses and exoskeletons, aim at adding extra effectors (i.e., arms, legs, or fingers) to the human user, rather than substituting or enhancing the natural ones. However, it is still undefined whether the use of supernumerary robotic limbs could specifically lead to neural modifications in brain dynamics. The illusion of owning the part of body has been already proven in many experimental observations, such as those relying on multisensory integration (e...

Snoring is a very common often underestimated sleep disorder, which is caused by a partial blockage of the upper airways. It can easily be treated by changing the sleeping posture of the snorer. However, conventional approaches are often perceived as uncomfortable. In order to increase uptake we propose to use an actuated bed, which is equipped with microphones and controlled in closed loop. The inclination of the part of the bed which is supporting the trunk is increased to open the upper airways, whenever snoring sounds are detected...

Robot-assisted therapy is regarded as an effective and reliable method for the delivery of highly repetitive rehabilitation training in restoring motor skills after a stroke. This study focuses on the rehabilitation of fine hand motion skills due to their vital role in performing delicate activities of daily living (ADL) tasks. The proposed rehabilitation system combines an adaptive assist-as-needed (AAN) control algorithm and a Virtual Reality (VR) based rehabilitation gaming system (RGS). The developed system is described and its effectiveness is validated through clinical trials on a group of eight subacute stroke patients for a period of six weeks...

We aimed to study therapeutic effects of antigravity treadmill (AlterG) training on reflex hyper-excitability, muscle stiffness, and corticospinal tract (CST) function in children with spastic hemiplegic cerebral palsy (CP). Three children received AlterG training 3 days per week for 8 weeks as experimental group. Each session lasted 45 minutes. One child as control group received typical occupational therapy for the same amount of time. We evaluated hyper-excitability of lower limb muscles by H-reflex response...

The capabilities of robotic gait assistive devices are ever increasing; however, their adoption outside of the lab is still limited. A critical barrier for the functionality of these devices are the still unknown mechanical properties of the human leg during dynamic conditions such as walking. We built a robotic knee exoskeleton to address this problem. Here, we present the effects of our device on the walking pattern of four subjects. We assessed the effects after a short period of acclimation as well as after a 1...

Ligaments within the human knee are commonly torn or injured as a result of sports that involve sharp direction changes, pivoting and landing. For this reason, athletes are often side-lined from their respective sports for up to 18 months after injury to rehabilitate. As part of the rehabilitation process, knee braces are often prescribed in an attempt to decrease the recovery period of the injured individual by restraining and minimizing the motion at the knee. However, the true efficacy of knee bracing is yet to be fully evaluated as studies show mixed results to whether braces actually decrease the rehabilitation period for patients...

Ming Wu, Chao-Jung Hsu, Janis Kim
The goal of this study was to determine how individuals post-stroke response to the lateral assistance force applied to the pelvis during treadmill walking. Ten individuals post chronic (> 6 months) stroke were recruited to participate in this study. A controlled assistance force (∼10% of body weight) was applied to the pelvis in the lateral direction toward the paretic side during stance of the paretic leg. Kinematics of the pelvis and legs were recorded. Applying pelvis assistance force facilitated weight shifting toward the paretic side, resulting in a more symmetrical gait pattern but also inducing an enlarged range of motion of the pelvis during early adaptation period...

We evaluated the therapeutic effects of anti-gravity locomotor treadmill (AlterG) training on postural stability in children with Cerebral Palsy (CP) and spasticity, particularly in the lower extremity. AlterG can facilitate walking by reducing the weight of CP children by up to 80%; it can also help subjects maintain an appropriate posture during the locomotor AlterG training. Thus, we hypothesized that AlterG training, for a sufficient period of time, has a potential to produce cerebellum neuroplasticity, and consequently result in an effective permanent postural stability...

Targeted muscle reinnervation (TMR) represents a breakthrough interface for prosthetic control in high-level upper-limb amputees. However, clinically, it is still limited to the direct motion-wise control restricted by the number of reinnervation sites. Pattern recognition may overcome this limitation. Previous studies on EMG classification in TMR patients experienced with myocontrol have shown greater accuracy when using high-density (HD) recordings compared to conventional single-channel derivations. This case study investigates the potential of HD-EMG classification longitudinally over a period of 17 months post-surgery in a glenohumeral amputee...

Knowledge of avian host responses to brucellosis is critical to understanding how avian resists this infection however this mechanism is not well established. On the other hand, temperature has a major involvement in the physiology of living organisms and cell death induced by heat is attributed to protein denaturation. This study demonstrates the direct bactericidal effect of a higher temperature (41ºC) to Brucella (B.) abortus that resulted in the gradual reduction of intracellular bacteria that inhibits bacterial growth within avian macrophage HD11 along an increasing period of time...

BACKGROUND: Although the burden of infectious diseases has decreased dramatically due to advances in health care, disease prevention and numerous public health efforts and innovations, zoonotic diseases continue to pose a problem in terms of both existing and emerging diseases. These risks are of particular concern in rural areas, in which there is more contact with animals for occupational and recreational purposes. As a rural and agricultural state, South Dakota has a large percentage of its population at risk of exposure to zoonotic diseases through their substantial contact time with animals...

INTRODUCTION: A patient's transition from hospitalization to discharge may represent an additional opportunity for antibiotic stewardship. METHODS: We reviewed antimicrobial drugs prescribed at discharge to patients at our medical center over a nine-month period, and calculated the total duration of inpatient and outpatient antibiotic therapy. RESULTS: The median duration of inpatient antibiotics was three days (interquartile range [IQR] four days), of outpatient antibiotics was seven days (IQR six days), and of total antibiotics 10 days (IQR six days)...

Zygomycosis refers to invasive fungal infections caused by fungi belonging to the phylum zygomycota. Infections generally occur in immunocompromised individuals. The following case is of a previously healthy 56 year-oldmale admitted to the hospital following a motor vehicle accident. During his hospitalization, there was a significant drop in hemoglobin with no obvious source of bleeding. This prompted the clinician to insert a nasogastric tube which returned at least 2 liters of black fluid and led to an upper gastrointestinal endoscopy...

BACKGROUND: Post-ward geriatric rehabilitation programs have hardly been developed and validated, which leaves a substantial gap in rehabilitative care in older adults and hinders full exploitation of maintained, but often unrecognized rehabilitation potentials. Geriatric rehabilitation patients with cognitive impairment represent a highly vulnerable population which is often affected by a lack of an ongoing support at the intersection between ward-based and post-ward rehabilitation. OBJECTIVE: To determine the effect of a standardized home-based training program in geriatric patients with cognitive impairment following ward-based rehabilitation...

The hypothesized role of deep coal mining in the development of community-based outbreaks of meningococcal meningitis has gone largely unexplored. Taking the coalfields of Britain as a historical testbed, techniques of linear and binomial logistic regression were used to assess the association between meningococcal meningitis rates and male occupation rates for coal mining in England and Wales during the national epidemic of 1931-32 and in its aftermath. Adjusting for the epidemiological effects of age, residential density, recent changes in the number of families, housing stock and low social class, the analysis yielded evidence of a significant and positive association between coal mining occupation rates and notified levels of meningitis activity in the epidemic period...

Rotavirus (RV) is highly endemic inside and outside hospital-settings. Immunocompromised children and adults are at risk of complicated rotavirus gastroenteritis (RVGE), but general rotavirus disease severity in this group remains poorly described and rotavirus testing is not routinely performed beyond infancy. We assessed rotavirus disease among immunocompromised hospitalized patients. METHODS: Rotavirus infections at a Dutch tertiary-care centre were identified from 5-year laboratory records...

BACKGROUND: Cancer patients have a high rate of emergency department (ED) visits and inpatient hospitalizations (IHs) that may be reduced by use of outpatient palliative care services. OBJECTIVE: To determine whether the outpatient adult palliative care service at the University of North Carolina (UNC) Hospital, begun in 2008, reduced the frequency of ED visits and IH during a two-year period. DESIGN: The charts of patients with lung cancer or head and neck cancer seen by the supportive care service from 2010 to 2011, and of a contemporaneous set of potential consults that were not seen, were retrospectively reviewed to determine the impact of this care delivery model...

BACKGROUND: The latest methacholine challenge testing (MCT) guidelines published by the European Respiratory Society recommend the characterization of nebulizers before their use in clinics and research. Such investigations are necessary for accurately determining the provocative dose of methacholine causing a 20% fall in FEV1 (PD20) delivered by a given device. The standard English Wright (Wright) jet nebulizer recommended in the 1999 guidelines by the American Thoracic Society has become difficult to obtain and possesses some characteristics that complicate the calculation of dose delivery from this device (e...
