INTRODUCTION: Although there has been substantial emphasis on the neuromuscular and cardiovascular adaptations following rehabilitation, pulmonary adaptations in individuals with incomplete SCI (iSCI) in response to locomotor training have been less frequently studied. In healthy individuals, effective transition from rest to work is accomplished by a hyperpneic response, which exhibits an exponential curve with three phases. However, the degree to which our current understanding of exercise hyperpnea can be applied to individuals with iSCI is unknown...

BACKGROUND: We investigated whether a volitional helpsheet (VHS), a brief psychological intervention, could reduce repeat self-harm in the 6 months following a suicide attempt. METHODS: We did a prospective, single-site, randomised controlled trial. Patients admitted to a hospital in Edinburgh, UK, after a suicide attempt were deemed eligible for the study if they were over the age of 16 years, had a self-reported history of self-harm, were fluent in English, were medically fit to interview, and were not participating in other research studies within the hospital...

Objective: Executive function consists of multiple cognitive processes that operate as an interactive system to produce volitional goal-oriented behavior, governed in large part by frontal microstructural and physiological networks. Identification of deficits in executive function in those with neurological or psychiatric conditions can be difficult because the normal variation in executive function test scores, in healthy adults when multiple tests are used, is largely unknown. This study addresses that gap in the literature by examining the prevalence of low scores on a brief battery of executive function tests...

BACKGROUND: Adolescence is associated with smoking initiation among men in China. The lack of qualitative studies using Chinese adolescent samples can pose challenges to enacting effective smoking prevention messages that resonate with male Chinese teenagers' thoughts, needs, and wishes. OBJECTIVE: This focus group study was designed to obtain in-depth contextual information on early smoking among male teenagers in China. METHODS: Twenty focus groups of 7-10 male students from vocational and junior colleges (N = 165) were conducted, approximately half in Shanxi and half in Guangdong...

Facial paralysis can be a devastating condition, causing disfiguring facial droop, slurred speech, eye dryness, scarring and blindness. This study investigated the utility of closed-loop functional electric stimulation (FES) for reanimating paralyzed facial muscles in a quantitative rodent model. The right buccal and marginal mandibular branches of the rat facial nerve were transected for selective, unilateral paralysis of whisker muscles. Microwire electrodes were implanted bilaterally into the facial musculature for FES and electromyographic (EMG) recording...

Binge drinking represents a public health issue and is a known risk factor in the development of alcohol use disorders. Previous studies have shown behavioural as well as neuroanatomical alterations associated with binge drinking. Here, we address the question of the automaticity or involuntary nature of the behaviour by assessing goal-directed behaviour and intentionality. In this study, we used a computational two-step task, designed to discern between model-based/goal-directed and model-free/habitual behaviours, and the classic Libet clock task, to study intention awareness, in a sample of 31 severe binge drinkers (BD) and 35 matched healthy volunteers...

BACKGROUND: Apraxia of eyelid opening (AEO) primarily has been described as bilateral loss of volitional ability to open the eyes at certain times and often associated with neurodegenerative disease. Rarely, it can occur in isolation and as an idiopathic phenomenon. There are a few reports of unilateral AEO only on awakening from sleep. We report an additional 11 patients with this unusual variation of AEO. METHODS: Retrospective, observational case series of patients collected from 3 separate neuro-ophthalmology practices...

REVIEW
T Fuchs, D Broschmann
At the beginning of modern psychopathology the notion of the will had a high significance. Thus, the works of Eugen Bleuler, Emil Krapelin and Karl Jaspers show an intensive study of disorders of the will, such as abulia, ambivalence or disorders of impulse control. Retrospectively, changes of the scientific paradigms in psychology could be one of the reasons for a break, which led to giving up the concept of the will in psychopathology. With increasing interest in issues of agency and free will, however, a reactivation of this central concept could close a gap in psychopathology as well as in therapeutic practice...

BACKGROUND: Ample evidence demonstrates that university students are at high risk for sedentary behaviors and inadequate fruit and vegetable intake (FVI). Internet-based interventions for multiple health behavior appear to be promising in changing such unhealthy habits. Limited randomized controlled trials have tested this assumption among Chinese university students. OBJECTIVE: Our objective was to test the efficacy of an 8-week Web-based intervention compared with a control group condition to improve physical activity (PA) and FVI in Chinese university students...

OBJECTIVE: Isolated female epispadias (IFE) is a rare congenital anomaly. The defect extends to the bladder neck, which is usually incompetent. The traditional surgical approach includes urethral and genital reconstruction in the first year, followed by bladder neck reconstruction (Young-Dees-Leadbetter cervicoplasty (YDL)) at the age of social continence. An alternative single-stage technique includes urethral, bladder neck and clitoris repair by a perineal approach. The aim of the present study was to describe long-term follow-up of patients who underwent the traditional vs alternative approach...

We report a case of chronic traumatic paraplegia in which epidural electrical stimulation (EES) of the lumbosacral spinal cord enabled (1) volitional control of task-specific muscle activity, (2) volitional control of rhythmic muscle activity to produce steplike movements while side-lying, (3) independent standing, and (4) while in a vertical position with body weight partially supported, voluntary control of steplike movements and rhythmic muscle activity. This is the first time that the application of EES enabled all of these tasks in the same patient within the first 2 weeks (8 stimulation sessions total) of EES therapy...

Individual differences in dopaminergic tone underlie tendencies to learn from reward versus punishment. These effects are well documented in Parkinson's patients, who vacillate between low and high tonic dopaminergic states as a function of medication. Yet very few studies have investigated the influence of higher-level cognitive states known to affect downstream dopaminergic learning in Parkinson's patients. A dopamine-dependent cognitive influence over learning would provide a candidate mechanism for declining cognitive integrity and motivation in Parkinson's patients...

Despite extensive research investigating obesity, the problem continues to increase, particularly in poor, minority, and under-resourced communities. However, the literature continues to demonstrate many obesity-predicating variables are outside of personal volitional control, such as food-related consumer behaviors, which are strongly influenced by income and environment. This cross-sectional study (n = 5,109) employed secondary data analysis to quantitatively examine the effect of food-related consumer variables on obesity while controlling for covariates...

OBJECTIVE: Recent brain-computer interface (BCI) assisted stroke rehabilitation protocols tend to focus on sensorimotor activity of the brain. Relying on evidence claiming that a variety of brain rhythms beyond sensorimotor areas are related to the extent of motor deficits, we propose to identify neural correlates of motor learning beyond sensorimotor areas spatially and spectrally for further use in novel BCI-assisted neurorehabilitation settings. APPROACH: Electroencephalographic (EEG) data were recorded from healthy subjects participating in a physical force-field adaptation task involving reaching movements through a robotic handle...

Central hypoventilation, also known as Ondine's curse, results from an impairment of the autonomic respiratory drive. It is characterized by an attenuated or absent respiratory response to hypoxemia and hypercapnia with preservation of volitional respiratory function. RJ was a 75-year-old woman with a diagnosis of probably PSP who developed central hypoventilation approximately four years after her initial onset of symptoms. Brain MRI showed no evidence of medullary lesions, one of the more common causes of adult onset central hypoventilation...

Human voluntary actions are often associated with a distinctive subjective experience termed 'sense of agency'. This experience could be a reconstructive inference triggered by monitoring one's actions and their outcomes, or a read-out of brain processes related to action preparation, or some hybrid of these. Participants pressed a key with the right index finger at a time of their own choice, while viewing a rotating clock. Occasionally they received a mild shock on the same finger. They were instructed to press the key as quickly as possible if they felt a shock...

BACKGROUND: People with chronic tetraplegia, due to high-cervical spinal cord injury, can regain limb movements through coordinated electrical stimulation of peripheral muscles and nerves, known as functional electrical stimulation (FES). Users typically command FES systems through other preserved, but unrelated and limited in number, volitional movements (eg, facial muscle activity, head movements, shoulder shrugs). We report the findings of an individual with traumatic high-cervical spinal cord injury who coordinated reaching and grasping movements using his own paralysed arm and hand, reanimated through implanted FES, and commanded using his own cortical signals through an intracortical brain-computer interface (iBCI)...

BACKGROUND: Cough is an airway protective mechanism that serves to detect and forcefully eject aspirate material. Existing research has identified the ability of healthy young adults to suppress, or modify cough motor output based on external cueing. However, no study has evaluated the ability of people with Parkinson's disease (PD) and healthy older adults (HOAs) to up-regulate cough motor output. The goal of this study was to evaluate the ability of people with PD and healthy age-matched controls (HOAs) to volitionally up-regulate reflex and voluntary cough function with verbal instruction and visual biofeedback of airflow targets...

BACKGROUND: The diagnosis and assessment of COPD rely mainly on the use of spirometry, which is an effort-dependent test and requires good patient cooperation. Impulse oscillometry (IOS) is a non-volitional method that requires less effort and cooperation and presents advantages for geriatric patients. However, the clinical application value of IOS in geriatric patients with COPD remains unclear. AIM: The aim of this study was to investigate the clinical application value of IOS in geriatric patients with COPD...
