BACKGROUND: To examine the associations between the functioning of patients with severe traumatic brain injury (TBI), and their relatives' coping style and quality of life across 12 months post-injury. METHODS: Prospective, population-based cohort study assessing 188 patients with severe TBI (Abbreviated Injury Scale of the head region [HAIS] score >3), and their relatives, 3, 6 and 12 months post-injury. Data were drawn from a larger national study run in Switzerland (2007-2011)...

This paper presents the iterative development of an artificially intelligent system to promote home-based neurorehabilitation. Although proper, structured practice of rehabilitation exercises at home is the key to successful recovery of motor functions, there is no home-program out there which can monitor a patient's exercise-related activities and provide corrective feedback in real time. To this end, we designed a Learning from Demonstration (LfD) based home-rehabilitation framework that combines advanced robot learning algorithms with commercially available wearable technologies...

Motor impairments come in different forms. One class of motor impairments, relates to accuracy of tracking a moving object, as, for instance, when chasing in an attempt to catch it. Here we look at neural signals associated with errors in tracking, and the implications for brain-computer-interfaces that target impairment-tailored rehabilitation. As a starting point, we characterized EEG signals evoked by tracking errors during continuous natural motion, in healthy participants. Participants played a virtual 3D, ecologically valid haptic tennis game, and had to track a moving tennis ball in order to hit and send the ball towards the opponent's court...

Brain-machine interfaces (BMI) can be used to control robotic and prosthetic devices for rehabilitation of motor disorders, such as stroke. The calibration of these BMI systems is of paramount importance in order to establish a precise contingent link between the brain activity related to movement intention and the peripheral feedback. However, electroencephalographic (EEG) activity, commonly used to build non-invasive BMIs, can be easily contaminated by artifacts of electrical or physiological origin. The way these interferences can affect the performance of movement intention decoders has not been deeply studied, especially when dealing with severely paralyzed patients, which often generate more artifacts by compensatory movements...

Multiplayer environments are thought to increase the training intensity in robot-aided rehabilitation therapy after stroke. We developed a haptic-based environment to investigate the dynamics of two-player training performing time-constrained reaching movements using the ARMin rehabilitation robot. We implemented a challenge level adaptation algorithm that controlled a virtual damping coefficient to reach a desired success rate. We tested the algorithm's effectiveness in regulating the success rate during game play in a simulation with computer-controlled players, in a feasibility study with six unimpaired players, and in a single session with one stroke patient...

Transcranial direct stimulation (tDCS) is a technique for modulating brain excitability that has potential to be used in motor neurorehabilitation by enhancing motor activity, such as motor imagery (MI). tDCS effects depend on different factors, like current density and the position of the stimulating electrodes. This study presents preliminary results of the evaluation of the effect of current density on MI performance by measuring right-hand/feet MI accuracy of classification from electroencephalographic (EEG) measurements after anodal tDCS is applied with a 4×1 ring montage over the right-hand or feet motor cortex...

Repetitive and task specific robot-based rehabilitation has been proved to be effective for motor recovery over time. During a therapy, the task should improve subject's impaired movements, but also enhance their efforts for a more effective recovery. This requires an accurate tuning of the task difficulty, which should be tailored directly to the patient. In this work, we propose a system for real-time assistance adaptation based on online performance evaluation for post-stroke subjects. In particular, the aim of the system is to implement the "assist-as-needed" paradigm based on actual patients' motor skills during a therapy session with an active upper-limb robotic exoskeleton...

Robotic devices can train strength, coordination, or a combination of both. If a robotic device focuses on coordination, what happens to strength recovery, and vice versa? Understanding this interaction could help optimize robotic training. We developed a computational neurorehabilitation model to gain insight into the interaction between strength and coordination recovery after stroke. In the model, the motor system recovers by optimizing the activity of residual corticospinal cells (focally connected, excitatory and inhibitory) and reticulospinal cells (diffusely connected and excitatory) to achieve a motor task...

There is a demand for a new neurorehabilitation modality with a brain-computer interface for stroke patients with insufficient or no remaining hand motor function. We previously developed a robotic hand rehabilitation system triggered by multichannel near-infrared spectroscopy (NIRS) to address this demand. In a preliminary prototype system, a robotic hand orthosis, providing one degree-of-freedom motion for a hand's closing and opening, is triggered by a wireless command from a NIRS system, capturing a subject's motor cortex activation...

BACKGROUND AND OBJECTIVES: The number of patients with multiresistant bacteria (MRB) in rehabilitation facilities is increasing. The increasing costs of hygienic isolation measures reduce resources available for core rehabilitation services. In addition to the existing lack of care, patients with MRB are at further risk of being given lower priority for admission to rehabilitation facilities. Therefore, the Hygiene Commission of the German Society for Neurorehabilitation (DGNR) attempted to quantify the overall risk for deterioration of rehabilitation care due to the financial burden of MRB...

PURPOSE: Neurorehabilitation aims to increase independence and participation in ordinary life. It is argued that the fundamental indices of this are independent living and engagement in occupational or productive activity. The Brain Injury Rehabilitation Trust Independent Living Scale was designed to capture change in levels of participation and independence following neurorehabilitation. With greater use of outcome measures in health care, it becomes necessary to develop tools which are simple to use and that capture the holistic impact of rehabilitation...

Facilitating functional recovery following brain injury is a key goal of neurorehabilitation. Direct, objective measures of changes in the brain are critical to understanding how and when meaningful changes occur, however, assessing neuroplasticity using brain based results remains a significant challenge. Little is known about the underlying changes in functional brain networks that correlate with cognitive outcomes in traumatic brain injury (TBI). The purpose of this pilot study was to assess the feasibility of an intensive three month cognitive intervention program in individuals with chronic TBI and to evaluate the effects of this intervention on brain-behavioral relationships...

BACKGROUND: Returning to employment is a major modifiable factor affecting long-term health in brain injury which neurological and vocational rehabilitation attempts to address. In military patients, little is known about long-term employability, whether employment is sustained and how they fare in civilian roles. METHODS: A telephone review was undertaken of every military patient having undergone inpatient neurorehabilitation between 2012 and 2014. This was compared to their employment outcomes one to three years post discharge...

OBJECTIVE: Botulinum neurotoxin is commonly utilized in neurorehabilitation as a treatment for focal spasticity. Clinical experience has yielded observations of late motor recovery after intramuscular injection of botulinum neurotoxin, that are not readily explained by the classical mechanism of action of the neurotoxin in controlling spasticity. These findings have triggered speculation regarding a botulinum neurotoxin mediated effect at the central level after peripheral intervention...

The purpose of this pilot study was to explore and interpret the way that individuals with acquired brain injury, admitted to inpatient neurorehabilitation with severe eating difficulties, experienced eating nine to fifteen months after discharge. Four individuals with acquired brain injury were interviewed via qualitative semi-structured interviews. An explorative study was conducted to study eating difficulties. Qualitative content analysis was used. Four main themes emerged from the analysis: personal values related to eating, swallowing difficulties, eating and drinking, meals and social life...

Homocystinuria (HCU) is a rare autosomal recessive disease characterized by the deficiency of cystathionine β-synthetase, presenting with variable clinical features including micronutrient deficiency-related osteoporosis. Early-onset osteoporosis results in increased bone fragility, which is associated with low-impact fractures. To date, no traumatic myelopathy has ever been described in patients with HCU. This case report describes a 30-year-old male patient with HCU who was not aware that he was at high risk of sustaining debilitating bone fractures...

Human and animal studies have documented that neural circuitries in the spinal cord show adaptive changes caused by altered supraspinal and/or afferent input to the spinal circuitry in relation to learning, immobilization, injury and neurorehabilitation. Reversible adaptations following, e.g. the acquisition or refinement of a motor skill rely heavily on the functional integration between supraspinal and sensory inputs to the spinal cord networks. Accordingly, what is frequently conceived as a change in the spinal circuitry may be a change in either descending or afferent input or in the relative integration of these, i...

It is widely accepted that cerebral pathology can impair ocular motor and manual motor control. This is true in indolent and chronic processes, such as neurodegeneration and in acute processes such as stroke or those secondary to neurotrauma. More recently, it has been suggested that disruptions in these control systems are useful markers for prognostication and longitudinal monitoring. The utility of examining the relationship or the coupling between these systems has yet to be determined. We measured eye and hand-movement control in chronic, middle cerebral artery stroke, relative to healthy controls, in saccade-to-reach paradigms to assess eye-hand coordination...

The cervical spine is the most common site of traumatic vertebral column injuries. Respiratory insufficiency constitutes a significant proportion of the morbidity burden and is the most common cause of mortality in these patients. In seeking to enhance our capacity to treat specifically the respiratory dysfunction following spinal cord injury, investigators have studied the "crossed phrenic phenomenon", wherein contraction of a hemidiaphragm paralyzed by a complete hemisection of the ipsilateral cervical spinal cord above the phrenic nucleus can be induced by respiratory stressors and recovers spontaneously over time...
