GH responses to two consecutive bouts of neuromuscular electrical stimulation in healthy adults.
2008
BackgroundIt is well established that repeated GHRH administration or repeated voluntary exercise bouts are associated with a complete blunting of GH responsiveness when the administration of the second stimulus follows the first one after a 2-h interval.AimTo evaluate GH responses to neuromuscular electrical stimulation (NMES) in healthy adults.MethodsSix volunteers (mean age±s.d. 31.7±5.5 years) were studied before and after two consecutive bouts of NMES exercise (a series of 20 contractions at the maximum of individual tolerance, frequency: 75 Hz, pulse duration: 400 μs, on–off ratio: 6.25–20 s) administered at a 2-h interval.ResultsBaseline GH levels (mean: 0.3±0.2 ng/ml) significantly …
Effects of a short video feedback intervention on enhancing maternal sensitivity and infant development in low-income families
2019
This study evaluated the effects of a short video feedback intervention aimed at enhancing maternal sensitivity and the development of infants from low-income families in a randomized controlled trial. Forty-four mother-infant dyads living in low-income communities from Salvador, Brazil were randomly assigned between intervention and control groups. Maternal sensitivity was assessed during free-play and infant development was evaluated with a standardized scale. Intervention took place in eight home visits between the infant's third and tenth month. Results showed mothers in the intervention group interpreted the meaning of their infants' behavior more often (r = 0.33), asked babies more qu…
Modeling of Human Posturokinetic Movements by a Linear Feedback System: Relations among Feedback Coefficients
2002
This study describes a method of modeling human trunk and whole body backward bending and suggests a possible neural control strategy. The hypothesis was that the control system can be modeled as a linear feedback system, in which the torque acting at a given joint is a function of the state variables (angular positions and angular velocities). The linear system enabled representation of the feedback system by a gain matrix. The matrix was computed from the kinematics recorded by a movement analysis system and from the joint torques calculated by inverse dynamics. To validate the control model, a comparison was made between the angular kinematics yielded by the model and the experimental d…
Effectiveness of Mirror Therapy for Subacute Stroke in Relation to Chosen Factors.
2016
Purpose The aim of this study was to determine the effectiveness of mirror therapy (MT) combined with comprehensive treatment and to investigate the possible relationships of functional state. Design Prospective, controlled trial of 60 stroke inpatients. Methods The Functional Index "Repty" (FIR) was an outcome measure to assess changes of independence in daily activities. The Frenchay Arm Test (FAT) and Motor Status Score were outcome measures to assess changes in hand function. Findings The analysis of pre- and posttest data indicated a significant improvement in hand function ([INCREMENT]FAT in the Mirror group p = .035, N = 30). Age factor indicated a significant change in relation to F…
Psychodynamic Online Treatment Following Supportive Expressive Therapy (SET):Therapeutic Rationale, Interventions and Treatment Process.
2018
The feasibility of psychodynamic online treatments has remained an issue of debate. The paper presents rationale and technique of a psychodynamic online intervention discussing therapeutic process and alliance based on two case examples from an RCT.A weekly writing task is followed by individual feedback from the online therapist. Treatment focuses on a 'Core Conflict Relationship Theme' based on relationship episodes according to the wish of the patient, reactions of the others and reactions of the self. Maladaptive interpersonal interactions are worked through by supportive and expressive therapeutic interventions.Case reports from our study illustrate a productive therapeutic process wit…
Competence feedback improves CBT competence in trainee therapists: A randomized controlled pilot study.
2016
The development and improvement of therapeutic competencies are central aims in psychotherapy training; however, little is known about which training interventions are suitable for the improvement of competencies.In the current pilot study, the efficacy of feedback regarding therapeutic competencies was investigated in cognitive behavioural therapy (CBT). Totally 19 trainee therapists and 19 patients were allocated randomly to a competence feedback group (CFG) or control group (CG). Two experienced clinicians and feedback providers who were blind to the treatment conditions independently evaluated therapeutic competencies on the Cognitive Therapy Scale at five treatment times (i.e., at Sess…
Patients' and therapists' experiences of general change mechanisms during bug-in-the-eye and delayed video-based supervised cognitive-behavioral ther…
2016
Objective This secondary analysis of a randomized controlled trial investigated whether bug-in-the-eye (BITE) supervision (live computer-based supervision during a psychotherapy session) affects the manner in which patients and therapists experience general change mechanisms (GCMs) during cognitive-behavioral therapy (CBT). Method A total of 23 therapists were randomized either to the BITE condition or the control condition (delayed video-based [DVB] supervision). After each session, both patients (BITE: n = 19; DVB: n = 23) and therapists (BITE: n = 11; DVB: n = 12) completed the Helping Alliance Questionnaire (HAQ) and the Bernese Post Session Report (BPSR). The HAQ total score and the 3 …
Contingent biofeedback outperforms other methods to enhance the accuracy of cardiac interoception: A comparison of short interventions.
2019
Abstract Background and objectives Deviations in interoception might contribute to the development and maintenance of mental disorders. The improvement of interoceptive accuracy (IA) is desirable but assessment and training methods remain controversial. For instance, it was assumed that performance increases in heartbeat counting paradigms after cardiac feedback were due to an improvement of knowledge with regard to heart rate rather than due to an actual improvement in IA. Methods Here, we examined effects of contingent cardiac feedback training, non-contingent cardiac feedback, mindfulness practice, and a waiting period with external attentional focus on IA. 100 healthy participants under…
Dynamic accommodation without feedback does not respond to isolated blur cues
2016
Highlights • A new methodology is used to study a potential cue for dynamic accommodation. • We show that human accommodation is not driven correctly by defocus alone. • Accommodation is most efficient using changes in stimulus vergence with feedback.
Effects of a single session of SMR neurofeedback training on anxiety and cortisol levels.
2020
Objectives: According to some studies, a putatively calming effect of EEG neurofeedback training could be useful as a therapeutic tool in psychiatric practice. With the aim of elucidating this possibility, we tested the efficacy of a single session of ¿sensorimotor (SMR)/¿theta neurofeedback training for mood improvement in 32 healthy men, taking into account trainability, independence and interpretability of the results. Methods: A pre-post design, with the following dependent variables, was applied: (i) psychometric measures of mood with regards to anxiety, depression, and anger (Profile of Mood State, POMS, and State Trait Anxiety Inventory, STAI); (ii) biological measures (salivary leve…
