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...

Lower limb exoskeletons have already proven the capability to give back mobility to people suffering from spinal cord injury (SCI). Other important populations such as people with multiple sclerosis or muscular dystrophy, frail elderly and stroke victims, suffer from severe gait impairments and could benefit from similar technology. The work presented in the current paper describes a novel design of a 6-actuated degrees of freedom (DOFs) assistive lower limb exoskeleton for people with moderate mobility impairments...

Lower Limb Exoskeleton robot that can facilitate stair walking is a big challenge, most systems could only provide level ground walking. In this study, a lightweight (0.5kg at ankle, 0.5kg at waist for control box) and autonomous exoskeleton Ankle Robot was proposed to provide power assistance for gait training of chronic stroke patients and it can facilitate three walking conditions in real-time: (1) level walking, (2) stair ascending, and (3) stair descending. Chronic stroke patients (n=3) with drop foot gait deficit and moderate motor impairment were recruited to evaluate the system under different walking conditions (Functional Ambulatory Category: FAC=4...

The main goal of this study is to investigate the potential of the Leap Motion Controller (LMC) for the objective assessment of motor dysfunctioning in patients with Parkinson's disease (PwPD). The most relevant clinical signs in Parkinson's Disease (PD), such as slowness of movements, frequency variation, amplitude variation, and speed, were extracted from the recorded LMC data. Data were clinically quantified using the LMC software development kit (SDK). In this study, 16 PwPD subjects and 12 control healthy subjects were involved...

The optimal conditions inducing proper brain activation during performance of rehabilitation robots should be examined to enhance the efficiency of robot rehabilitation based on the concept of brain plasticity. In this study, we attempted to investigate differences in cortical activation according to the speeds of passive wrist movements performed by a rehabilitation robot for stroke patients. 9 stroke patients with right hemiparesis participated in this study. Passive movements of the affected wrist were performed by the rehabilitation robot at three different speeds: 0...

Cocaine addiction is a chronic relapsing disorder characterized by persistent perturbations to an organism's homeostatic processes that result in maladaptive drug seeking. Although considerable attention has been directed at the consequences of neuronal changes following chronic cocaine taking, few studies have examined the role of microglia, the brain's resident immune cells, following chronic cocaine administration. Toll-Like Receptor 4 (TLR4) is a molecular pattern receptor that recognizes pathogens, danger signals, and xenobiotics and induces proinflammatory signaling in the central nervous system...

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...

AIMS: Glomerular insudative lesions are a pathological hallmark of diabetic nephropathy (DN). However, paratubular basement membrane insudative lesions (PTBMIL) have not attracted much attention, and the association between such lesions and the renal prognosis remains unclear. METHODS: Among 142 patients with biopsy-proven DN and type 2 diabetes encountered from 1998 to 2011, 136 patients were enrolled in this study. Patients were classified into 3 groups (Group 1: mild, Group 2: moderate, Group 3: severe) according to the extent of cortical and medullary PTBMIL...

REVIEW
April S Masarik, Rand D Conger
In the present report, we provide an illustrative review of the Family Stress Model (FSM) framework [1] to understand how family stress influences children across development in physical, social-emotional, and cognitive domains. We note that the FSM as a theory has evolved through inspection of: (a) new explanatory pathways (mediators); (b) factors that moderate FSM pathways; and (c) joint tests of competing models. Also important, most researchers cited in this review used longitudinal designs to test the proposed causal ordering of FSM pathways, which replicated among a diverse set of families varied in structure, ethnic background, and geographic location...

Couple Relationship Education (RE) seeks to enrich couples' relationships, and assist them to manage stressful life events [1]. In the current paper we present an ecological model of couple relationships intended to guide the practice of RE, analyze the mediators of RE effects, and suggest future research needs to assess moderators and mediators of RE effects in order to enhance the impact of RE.

The birth of the first baby-often referred to as the transition to parenthood (TTP)-is both a time of great joy and great stress for new parents. Although the literature is mixed, the preponderance of evidence suggests that the TTP has a negative effect on relationship functioning for most couples. However, as children age, the relationship functioning of parents and non-parents converge. Notably, there are important moderators of this average trajectory; couples with higher levels of pre-birth relationship problems, insecurely attached parents, temperamentally difficult infants, and TTP following biological birth rather than adoption are associated with larger post-birth declines...

The Incredible Years parenting intervention is a social learning theory-based programme for reducing children's conduct problems. Dozens of randomized trials, many by independent investigators, find consistent effects of Incredible Years on children's conduct problems across multiple countries and settings. However, in common with other interventions, these average effects hide much variability in the responses of individual children and families. Innovative moderator research is needed to enhance scientific understanding of why individual children and parents respond differently to intervention...

Judith G Smetana
For decades, parenting has been characterized in terms of broad global styles, with authoritative parenting seen as most beneficial for children's development. Concerns with greater sensitivity to cultural and contextual variations have led to greater specificity in defining parenting in terms of different parenting dimensions and greater consideration of the role of parenting beliefs in moderating links between parenting and adjustment. New research includes 'domain-specific' models that describe parents as flexibly deploying different practices depending on their goals, children's needs, and the types of behaviors towards which parenting is directed...

In the decades since social learning parenting interventions emerged, many evidence-based programs have been implemented at scale in community settings, and much research is now focusing on ways to maintain fidelity and impact during the implementation process. Notably, a considerable amount of theoretical confluence has occurred in parenting interventions from social learning, attachment, and other theoretical perspectives, with parent coaching as an example of this new generation of relational interventions...

Geertjan Overbeek
Recent research suggests that children's heightened susceptibility to parenting may have a (poly)genetic basis, and may be grounded in children's temperament. However, much current evidence is of a preliminary-correlational-nature. Because in correlational designs alternative explanations for gene-environment (G×E) or temperament-environment (T×E) interactions cannot be discounted, it is pivotal to conduct experimental studies in which parenting is actively manipulated. Based on data from a recently conducted randomized trial (n=387) of the Incredible Years parenting intervention, experimental evidence is provided for G×E and T×E interactions in an at-risk population of children aged 4-8 years...

Intervention efforts aimed at remediating or preventing problems in children typically prove only moderately effective due to substantial heterogeneity in their efficacy. It thus becomes important to account for such variation in intervention efficacy. Here we summarize illustrative evidence that, due to their genetic make-up, some children benefit more from interventions targeting parenting than do others. Whereas some work documents the role of single, 'candidate' genes, other work reveals the utility of compositing multiple genes and genetic pathways...

BACKGROUND: Affiliating with 12-step groups appears to reduce relapse risk. By relying on between-person designs, extant research has been unable to examine daily mechanisms through which 12-step group affiliation contributes to recovery. OBJECTIVES: To examine the daily use and factor structure of the 12 steps and intrapersonal predictors and moderators of 12-step use. To determine whether the 12 steps were used in response to daily craving and, if so, which steps and in what contexts...

The concept of Chronic Obstructive Pulmonary Disease (COPD) control has been developed to inform therapeutic decision-making. We explored the validity of a definition of COPD control in a representative population of patients with COPD in the United Kingdom. Electronic medical records and linked COPD questionnaire data from the Optimum Patient Care Research Database were used to characterize control status. Patients were aged ≥40 years, with spirometry-confirmed COPD, current or ex-smokers, and continuous records throughout the study period...

A PEG-based cyclized vinyl polymer was synthesized via one-step RAFT polymerization and used as a precursor of injectable hydrogels. Dithiol linkers including laminin-derived peptides containing IKVAV and YIGSR sequences and DTT were used for gelation. Fast and adjustable gelation rate was achieved through nucleophile-initiated thiol-Michael reaction under physiological conditions. Low swelling ratio and moderate degradation rate of the formed hydrogels were observed. 3D encapsulation of neural progenitor cells in the synthetic hydrogel showed good cell viability over 8 days...
