INTRODUCTION/BACKGROUND:To demonstrate the broad utility of the remotely supervised transcranial direct current stimulation (RS-tDCS) protocol developed to deliver at-home rehabilitation for individuals with multiple sclerosis (MS). METHODS:Stimulation delivered with the RS-tDCS protocol and paired with adaptive cognitive training was delivered to three different study groups of MS patients to determine the feasibility and tolerability of the protocol. The three studies each used consecutively increasing amounts of stimulation amperage (1.5, 2.0, and 2.5 mA, respectively) and session numbers (10, 20, and 40 sessions, respectively). RESULTS:High feasibility and tolerability of the stimulation were observed for n = 99 participants across three tDCS pilot studies. CONCLUSIONS:RS-tDCS is feasible and tolerable for MS participants. The RS-tDCS protocol can be used to reach those in locations without clinic access and be paired with training or rehabilitation in locations away from the clinic. This protocol could be used to deliver tDCS paired with training or rehabilitation activities remotely to service members and veterans.

Unprecedented media coverage of concussion in sport has led to increased fears regarding the potential negative effects of participation in contact sports including North American football and ice hockey. Initial responses of professional sports leagues to implementation of acute concussion management practices and reports of a neurodegenerative condition known as chronic traumatic encephalopathy (CTE) developing in retired players caused an atmosphere of distrust whereby the leagues were accused of maintaining cover-ups analogous to what had been seen in association with studies of tobacco and smoking. This article reviews the important role that psychology has played in the study of sports concussion and in the establishment of methods currently used to diagnose and track concussion symptoms. Results of existing studies have shown that the neurobiological effects of concussion are rather short-lived with development of persisting symptoms in some individuals associated more with psychosocial factors than underlying physiological effects. With regard to CTE, the status of the science remains preliminary with little definitive information known about its epidemiology or cause. In the midst of the ongoing controversy, a polarized climate has developed in association with concussion and CTE, divided by believers in the dangers of long-term consequences and deniers who question the status of the existing science. The conclusion is that it is important for psychology to extend its scope of study to provide increased understanding of the social factors underlying the current polarized climate while continuing to provide the public with an accurate and reliable account of the existing science.

Controversies have emerged about the status of the science, creating polarization on the topic. Psychology has provided significant contributions to our scientific knowledge on sports concussion and has the potential to provide a key to understanding the factors underlying division on these topics.

Les premières réponses des ligues sportives professionnelles à la mise en Å“uvre de pratiques de gestion des commotions aiguës et les déclarations de maladie neurodégénérative connue sous le nom d"™encéphalopathie traumatique chronique (CTE) en développement chez les joueurs retraités ont provoqué une atmosphère de méfiance où les ligues ont été accusées de dissimulations de manière similaire à ce qui avait été observé avec les études sur le tabac et le tabagisme. Le présent article examine le rôle important que la psychologie a joué dans l"™Ã©tude des commotions liées au sport et dans l"™Ã©tablissement de méthodes actuellement utilisées pour diagnostiquer et surveiller les symptômes de commotion cérébrale. Les résultats des études existantes ont montré que les effets neurobiologiques de commotion cérébrale sont plutôt de courte durée avec l"™apparition de symptômes persistants, chez certaines personnes, plutôt associés à des facteurs psychosociaux qu"™aux effets physiologiques sous-jacents. En ce qui concerne la CTE, le statut de la science reste préliminaire, avec peu de renseignements définitifs connus sur son épidémiologie ou sa cause. Au cÅ“ur de la controverse actuelle, un climat polarisé s"™est développé en lien avec la commotion cérébrale et la CTE, divisé par les croyants aux dangers des conséquences à long terme et les négateurs qui remettent en question le statut de la science existante. En conclusion, il est important pour la psychologie d"™Ã©tendre sa portée d"™Ã©tude afin de mieux comprendre les facteurs sociaux sous-jacents au climat polarisé actuel tout en continuant à fournir au public un compte rendu exact et fiable de la science existante.
