Effect of the App-Based Video Guidance on Prenatal Pelvic Floor Muscle Training Combined with Global Postural Re-education for Stress Urinary Incontinence Prevention: A Protocol for a Multicenter, Randomized Controlled Trial

Background: As the effectiveness on stress urinary incontinence (SUI) prevention of pelvic floor muscle training (PFMT) for pregnant women has been inconclusive, we are planning to conduct a trial to evaluate a video program designed for prevention of SUI developed through combining PFMT with global postural reeducation (GPR). Methods: As a randomized controlled trial, eligible participants will be randomized (1:1) into an exercise group and a control group to perform PFMT regularly following video guidance or with no intervention, respectively. The experimental stage will be from the 16th gestation week (GW) to the 12th month postpartum, with eight appointments at the 16th, 28th, 37th GW, delivery, the 6th week and the 3rd, 6th, and 12th month postpartum. Data will be collected regarding urinary leakage symptoms, the stress test, the modified Oxford Scale, pelvic floor ultrasound, perineal laceration classification at delivery, neonatal Apgar score, and questionnaires (PISQ-12, ICIQ-UI SF, I-QOL, OABSS). The primary outcome is the occurrence of the symptomatic SUI and positive stress test at the 6th week postpartum. Discussion: This protocol is anticipated to evaluate the efficacy of the intervention via video app for the design of a future randomized control trial (RCT). Trial registration: The trial has been registered at Chinese Clinical Trial Registry (registration number: ChiCTR2000029618).

Like Taking a Magnifying Glass Into Everyday Life: Vulnerable Parents’ Experiences With Video Guidance in an Infant Mental Health Clinic

Background: Parents are a central focus in clinical infant mental health interventions because of the key importance of the caregiver-infant relationship, especially when dyads are burdened by psychosocial and parental mental health problems. However, knowledge is scarce about the lived experience of vulnerable parents who undergo video-based guidance.Aim: The study explores how parents in an infant-psychiatric outpatient clinic who struggled to mentalize and remain emotionally connected to their infant experienced helpful and challenging elements in video guidance.Method: We analyzed the interviews of a strategic sample of 12 parents after undergoing Marte Meo video guidance, using a team-based, reflexive thematic analysis (TA).Results: We identified four main themes: (a) Handling initial feelings of fear and loss of control; (b) Filming as a disturbing or agentic experience; (c) Feeling validated or devalued in the therapeutic relationship; and (d) Bringing insights from video guidance into everyday life. Therapeutic and existential factors became apparent in the main themes of adjustment to the guidance, experiences with filming, the therapeutic relationship and integration of new experiences.Conclusion: The parents’ sense of agency, dignity, and shame may be important for their ability to integrate new ideas about themselves.Implications: Video guidance for vulnerable parents in specialized clinical treatment should address relational challenges, parental mental health, and issues of recognition.

Learning to mentalize: Exploring vulnerable parents’ experiences of change during video guidance in an infant mental health clinic

Background Interventions that promote infant mental health face challenges when applied for parents who struggle with psychosocial and psychological burdens. Video-based guidance using the Marte Meo method is used in specialized clinical settings with high-risk families to improve parent-child interaction, parental sensitivity and mentalizing. However, knowledge about the lifeworlds of these parents and their experiences of the therapeutic process during video guidance is limited. Aim This qualitative study explores how parents in an infant mental health outpatient clinic who had difficulties mentalizing and maintaining an emotional connection with their infants experienced the change process during Marte Meo video guidance. Methods We identified a strategic sample of parents with difficulties mentalizing and maintaining an emotional connection with their infants through the Parent Development Interview. Twelve parents received video guidance and were afterwards interviewed in-depth. The research interviews were qualitatively analysed via a team-based reflexive thematic analysis. Result We identified four themes: a) feeling inadequate or disconnected as a parent; b) discovering the infant as a relating and intentional person; c) becoming more agentic and interconnected; and d) still feeling challenged by personal mental health issues. Conclusion Parents described positive changes in their interactions, in mentalizing their infants, the relationship and themselves as parents, in their experiences of self-efficacy and on a representational level. They also described increased confidence and improved coping despite ongoing personal mental health challenges. The findings suggest that video guidance using the Marte Meo method can be a critical intervention for vulnerable parents but should be coordinated with parents’ primary treatments when complex parental mental health issues are involved.

Visual imagination and cognitive mapping of a virtual building

We investigated the contribution of visual imagination to the cognitive mapping of a building when initial exploration was simulated either visually by using a passive video walk-through, or mentally by using verbal guidance. Building layout had repeating elements with either rotational or mirror symmetry. Cognitive mapping of the virtual building, determined using questionnaires and map drawings, was present following verbal guidance but inferior to that following video guidance. Mapping was not affected by the building's structural symmetry. However, notably, it correlated with small-scale mental rotation scores for both video and verbal guidance conditions. There was no difference between males and females. A common factor that may have influenced cognitive mapping was the availability of visual information about the relationships of the building elements, either directly perceived (during the video walk-through) or imagined (during the verbal walk-through and/or during recall). Differences in visual imagination, particularly mental rotation, may thus account for some of the individual variance in cognitive mapping of complex built environments, which is relevant to how designers provide navigation-relevant information.

Performance Characterization of the Smartphone Video Guidance Sensor as Vision-Based Positioning System

The Smartphone Video Guidance Sensor (SVGS) is a vision-based sensor that computes the six-state position and orientation vector of a target relative to a coordinate system attached to a smartphone. This paper presents accuracy-characterization measurements of the Smartphone Video Guidance Sensor (SVGS) to assess its performance as a position and attitude estimator, evaluating its accuracy in linear and angular motion for different velocities and various types of targets based on the mean and standard deviation errors between SVGS estimates and known motion profiles, in both linear and angular motions. The study also examines the effects of target velocity and sampling rate on the overall performance of SVGS and provides an overall assessment of SVGS’ performance as a position/attitude estimator. While the error metrics are dependent on range and camera resolution, the results of this paper can be scaled to other operational conditions by scaling the blob size in pixels (the light markers identified in the images) relative to the total resolution (number of pixels) of the image. The error statistics of SVGS enable its incorporation (by synthesis of a Kalman estimator) in advanced motion-control systems for navigation and guidance.

Proximity Operations and Three Degree-of-Freedom Maneuvers Using the Smartphone Video Guidance Sensor

This paper presents the first demonstration of NASA’s Smartphone Video Guidance Sensor (SVGS) as real-time position and attitude estimator for proximity and formation maneuvers. An optimal linear quadratic Gaussian controller was used, combining a linear quadratic regulator and a Kalman filter. The system was demonstrated controlling the 3-degree of freedom planar motion of the RINGS ground units (Resonant Inductive Near-field Generation Systems). A state-space model of the system’s 3-DOF motion dynamics was derived, and model parameters extracted using a system identification technique. The system’s motion control performance is experimentally demonstrated in both tracking and formation maneuvers. The results highlight the capabilities and performance of the Smartphone Video Guidance Sensor (SVGS) as a vision-based real-time position and attitude sensor for motion control, formation flight and proximity operations. A leader-follower formation maneuver approach is demonstrated, as well as position hold and path following.
