Filter by:A variety of rehabilitation techniques focused on improving disability after stroke have shown significant changes on walking speed, and endurance. Also, the administration of combined techniques showed better results. Previous studies have suggested that embedding behavioral strategies in neurorehabilitation protocols can enhance patient's adherence and participation outside the clinical setting. The addition of a group of behavioral strategies called Transfer Package (TP) has been widely used in motor training protocol (e.g. Constraint-Induced Movement Therapy). The TP has shown to enhance the effects of treatment 2.4 times when compared to motor training alone. However, the effect of TP when combined with robotic gait training remains unexplored. In this study our goal is to combine the TP with robotic gait training. The hypothesis is that using the TP in combination with robotic gait training will enhance the outcome of robotic gait training alone and will induce long term transference and retention of the motor skills observed after treatment. More importantly, this experimental intervention is more meaningful to the patient and can be more easily implemented on the clinical setting. The aims of this study are (1) to assess transfer and long-term retention of walking and balance skills after robotic treadmill gait training combined with the TP, (2) to understand participants' acceptability and perceptions of the TP as a tool to enhance transfer of skills to real-world situations, and (3) to examine the feasibility of these combined intervention to improve walking and balance after stroke.
This study aimed to examine the effect of the "I Am Protecting My Child from the Sun" program, based on social cognitive theory, on parents' sun-protection product use and sun avoidance behaviors. The "I Am Protecting My Child from the Sun" program, based on Social Cognitive Theory, and the sending of short reminder messages had positive effects on the parents' behaviors related to protecting themselves and their children from the sun.
This study evaluates the effect and experience of peer-support in internet mediated ACT (Acceptance and Commitment therapy) in an explorative pilot study with mixed method design conducted in primary care. Peer-supporters are certified support persons with personal experience of mental health problems and the process of rehabilitation, which becomes professionally active in care and support to patients in their recovery
The purpose of this study is to evaluate a text-message delivered approach for improving college adjustment and experience and reducing risky alcohol use in young adult college students. The study compares a text-message delivered brief motivational intervention for reducing alcohol use and increasing engagement in alcohol-free activities, to text-message delivered alcohol and nutrition education sessions. The investigators predict that individuals who receive the brief motivational intervention will report less alcohol use and fewer related problems 3 months following the intervention compared to those who receive the education sessions. The investigators also expect that these individuals will report greater engagement in alcohol-free activities compared to those who receive the education sessions.
To address the critical scientific gaps in PrEP safety for transgender youth and to plan for appropriate implementation of PrEP in transgender youth communities, the study will be conducted in 3 integrated phases. In Phase 1, a pharmacokinetic (PK) study exploring the interactions of cs-HT for both TW and TM youth on TDF/FTC will be conducted. Simultaneously, in Phase 2, ethnographic data via focus groups (FGs) and in-depth interviews (IDIs) to inform the development of a tailored intervention to improve uptake and adherence to PrEP for transgender youth will be collected. In Phase 3, a small demonstration trial of PrEP use in transgender youth, utilizing the ethnographically developed intervention to improve uptake and adherence, while also monitoring renal and bone safety outcomes will be implemented. The project has the following important specific aims: Aim 1: To evaluate the differential PK of TDF/FTC in a cohort of transgender youth on cs-HT by conducting a PK trial of daily TDF/FTC among 24 TW taking estradiol and 24 TM taking testosterone (ages 15-24 years) using video-based directly observed therapy (DOT) to insure daily adherence and maximize drug exposure. Aim 2: To develop a culturally, developmentally, and gender-affirmative intervention to increase uptake of and adherence to PrEP among TW and TM youth that is grounded in theory (Information-Motivation-Behavioral Skills Model of Behavior Change, Gender Affirmation, Empowerment Theory) and incorporates the PK data from Aim 1. Investigators will conduct FGs with young TW (N=20-30) and TM (N=20-30) and conduct IDIs with participants from the PK study (Total N=10-14). Investigators will solicit continuous input and feedback from TW and TM on the project's Youth Advisory Board. Aim 3: To conduct a small randomized controlled trial within a PrEP demonstration project comparing the newly developed intervention with standard of care (SOC) in TW (N=50) and TM (N=50) ages 15-24 years.

Recent studies indicate that obese teenagers exhibit memory disturbances. Adolescence represents a crucial period in the development of the hippocampus and the amygdala, necessary for the implementation of memory and emotional functions for the rest of life. Disturbances of the interaction between amygdala and hippocampus during adolescence have been associated with the development of neuropsychiatric disorders. However, the impact of juvenile obesity on functional amygdala-hippocampus connectivity has not been evaluated yet. The main objective of this study is to compare the emotional memory performance and the level of functional connectivity between the hippocampus and the amygdala during the realization of an emotional associative memory task, in obese and control adolescents.
Many women at high risk for acquiring HIV infection are not aware of preexposure prophylaxis (PrEP), an efficacious, self-administered, woman-controlled, HIV prevention product. The objective of this study is to evaluate the feasibility and acceptability of a theory-based intervention to promote PrEP uptake and adherence in a pilot trial among 80 women. The study will also measure intention to use PrEP and actual initiation of PrEP use. The investigators hypothesize that the intervention will be acceptable and feasible and that the intervention group will report higher levels of PrEP uptake, intention to use and adhere to PrEP, and other variables regarding PrEP uptake, comparing baseline, post-intervention and 3 month follow-up assessments.

In a recent study, investigators provided the first neuroscientific data on social facilitation. This neuroimaging study, performed in the macaque monkey, shows a marked improvement in performance in a simple task when a congener is present compared to when the animal performs the task alone. This social facilitation is accompanied by a significant increase in brain activity within the fronto-parietal network of attention. No variation in activity, however, is observed in the cerebral network of motivation. These results argue in favor of the implication of attentional processes in the phenomenon of social facilitation. The challenge now is to determine whether social facilitation is always based on the attention network (whatever the task) or, alternatively, whether it increases activity in any cerebral circuit involved depending on the task performed and the population studied. This hypothesis, which the investigators have named the "multi-mediator model of social facilitation", has the advantage of reconciling the attentional and motivational theories of social facilitation, which are not mutually exclusive. This hypothesis also provides an explanation for the pervasiveness (across species and different ages for humans) of social facilitation. The main objective of SOFEE is to gather neuroscientific evidence to support the multi-facilitator model of social facilitation.
