Evoking stable and precise tactile sensations via multi-electrode intracortical microstimulation of the somatosensory cortex.

Tactile feedback from brain-controlled bionic hands can be partially restored via intracortical microstimulation (ICMS) of the primary somatosensory cortex. In ICMS, the location of percepts depends on the electrode's location and the percept intensity depends on the stimulation frequency and amplitude. Sensors on a bionic hand can thus be linked to somatotopically appropriate electrodes, and the contact force of each sensor can be used to determine the amplitude of a stimulus.

Microstimulation of human somatosensory cortex evokes task-dependent, spatially patterned responses in motor cortex.

The primary motor (M1) and somatosensory (S1) cortices play critical roles in motor control but the signaling between these structures is poorly understood. To fill this gap, we recorded - in three participants in an ongoing human clinical trial (NCT01894802) for people with paralyzed hands - the responses evoked in the hand and arm representations of M1 during intracortical microstimulation (ICMS) in the hand representation of S1. We found that ICMS of S1 activated some M1 neurons at short, fixed latencies consistent with monosynaptic activation.

Tessellation of artificial touch via microstimulation of human somatosensory cortex.

When we interact with objects, we rely on signals from the hand that convey information about the object and our interaction with it. A basic feature of these interactions, the locations of contacts between the hand and object, is often only available via the sense of touch. Information about locations of contact between a brain-controlled bionic hand and an object can be signaled via intracortical microstimulation (ICMS) of somatosensory cortex (S1), which evokes touch sensations that are localized to a specific patch of skin.

Toward Cultural Competency in Health Care: A Scoping Review of the Diversity and Inclusion Education Literature.

Purpose: To explore best practices for increasing cultural competency and reducing health disparities, the authors conducted a scoping review of the existing literature.

Method: The review was guided by 2 questions: (1) Are health care professionals and medical students learning about implicit bias, health disparities, advocacy, and the needs of diverse patient populations? (2) What educational strategies are being used to increase student and educator cultural competency? In August 2016 and July 2018, the authors searched 10 databases (including Ovid MEDLINE, Embase, and Scopus) and MedEdPORTAL, respectively, using keywords related to multiple health professions and cultural competency or diversity and inclusion education and training. Publications from 2005 to August 2016 were included.

Leading Practices and Future Directions for Technical Standards in Medical Education.

The medical profession first addressed the need for technical standards (TS), defining the nonacademic requirements deemed essential for participation in an educational program, in guidelines published by the Association of American Medical Colleges in 1979. Despite many changes in the practice of medicine and legal, cultural, and technological advances that afford greater opportunities for people with disabilities, the profession's approach to TS largely has not changed over the ensuing four decades. Although physicians with disabilities bring unique perspectives to medicine and contribute to a diverse physician workforce of culturally competent practitioners, they remain underrepresented in the profession.

Brain Computer Interfaces in Rehabilitation Medicine.

One innovation currently influencing physical medicine and rehabilitation is brain-computer interface (BCI) technology. BCI systems used for motor control record neural activity associated with thoughts, perceptions, and motor intent; decode brain signals into commands for output devices; and perform the user's intended action through an output device. BCI systems used for sensory augmentation transduce environmental stimuli into neural signals interpretable by the central nervous system.

Novel Treatment Approach to Contraversive Pushing after Acute Stroke: A Case Report.

The purpose of this case report is to provide an alternative treatment approach to pushing behavior (PB), adapting widely used equipment for persons with stroke demonstrating such behaviour. The aim is to change their graviceptive experience during interventions while performing repeated stepping and righting practice to resolve PB more quickly. The subject is a man aged 56 years who sustained a right middle-cerebral-artery ischemic stroke.

Does the Physical Medicine and Rehabilitation Self-Assessment Examination for Residents Predict the Chances of Passing the Part 1 Board Certification Examination?

Background: Each year, residents in accredited United States Physical Medicine and Rehabilitation (PMR) residency programs can take the American Academy of Physical Medicine and Rehabilitation (AAPM&R) Self-Assessment Examination for Residents (SAE-R). This 150-question, multiple-choice examination is intended for self-assessment of physiatric knowledge, but its predictive value for performance on the part 1 American Board of Physical Medicine and Rehabilitation Certification Examination (ABPMR-CE) is unknown.

Objective: To investigate the predictive value of the SAE-R in relation to the part 1 ABPMR-CE.

Topical Ketamine 10% for Neuropathic Pain in Spinal Cord Injury Patients: An Open-Label Trial.

Topical ketamine, an N-methyl-D-aspartate antagonist, has been shown to be effective in certain neuropathic pain syndromes. The objective of this study was to determine the efficacy of topical ketamine in spinal cord injury patients with neuropathic pain. An open label trial enrolled five subjects at an outpatient rehabilitation hospital with traumatic spinal cord injuries who had neuropathic pain at or below the level of injury.

A Survey of Runners' Attitudes Toward and Experiences With Minimally Shod Running.

Objective: To investigate the characteristics, perceptions, motivating factors, experiences, and injury rates of runners who practice minimally shod running.

Design: Survey.

Setting: web-based questionnaire.

Exploring the scope of post-intensive care syndrome therapy and care: engagement of non-critical care providers and survivors in a second stakeholders meeting.

Background: Increasing numbers of survivors of critical illness are at risk for physical, cognitive, and/or mental health impairments that may persist for months or years after hospital discharge. The post-intensive care syndrome framework encompassing these multidimensional morbidities was developed at the 2010 Society of Critical Care Medicine conference on improving long-term outcomes after critical illness for survivors and their families.

Objectives: To report on engagement with non-critical care providers and survivors during the 2012 Society of Critical Care Medicine post-intensive care syndrome stakeholder conference.
