Is abdominal hollowing exercise using real-time ultrasound imaging feedback helpful for selective strengthening of the transversus abdominis muscle?: A prospective, randomized, parallel-group, comparative study.

Despite the importance of strengthening of the transversus abdominis (TrA) muscle in individuals with low back pain, the effect of real-time ultrasound imaging on maintenance in selective strengthening of abdominal hallowing exercise (AHE) performance has not been investigated. So, the aim of this study was to investigate the effects of AHE with real-time ultrasound imaging feedback on selective reinforcing the TrA muscle.Twenty healthy subjects were enrolled prospectively and randomized to train AHE for 2 ...


Behavioral interventions for reducing head motion during MRI scans in children.

A major limitation to structural and functional MRI (fMRI) scans is their susceptibility to head motion artifacts. Even submillimeter movements can systematically distort functional connectivity, morphometric, and diffusion imaging results. In patient care, sedation is often used to minimize head motion, but it incurs increased costs and risks. In research settings, sedation is typically not an ethical option. Therefore, safe methods that reduce head motion are critical for improving MRI quality, especially...

Using real-time fMRI brain-computer interfacing to treat eating disorders.

Real-time functional magnetic resonance imaging based brain-computer interfacing (fMRI neurofeedback) has shown encouraging outcomes in the treatment of psychiatric and behavioural disorders. However, its use in the treatment of eating disorders is very limited. Here, we give a brief overview of how to design and implement fMRI neurofeedback intervention for the treatment of eating disorders, considering the basic and essential components. We also attempt to develop potential adaptations of fMRI neurofeedba...


Apraxia of object-related action does not depend on visual feedback.

Pantomime of tool use is typically affected in neurological patients with apraxia, while at the same time these patients are able to perform the use of the actual tool with less or no errors. This discrepancy is commonly explained by differences in afferent input, in particular a lack of visual online feedback from the object in pantomime. The present study investigated the role of visual feedback in apraxia of pantomime by testing neurological patients with apraxia and healthy controls in a task requiring ...

How Are We Doing?-The Experience of the Merton Home Treatment Team in Gathering Real-Time Feedback and the Impact Upon Service Provision.

To discuss the methods involved in gathering real-time feedback (RTF) by a London Home Treatment Team. We hypothesized that RTF would lead to changes in service provision and improvements in patient and carer feedback. Patients were invited to provide RTF on discharge. Quantitative and qualitative data were collected and analyzed centrally by the Trust before being disseminated to the team and changes made based upon the results. Quantitative feedback on the team's performance in the first 6 months of RTF u...

Improving CPR quality with distributed practice and real-time feedback in pediatric healthcare providers - a randomized controlled trial.

Guideline compliant CPR is associated with improved survival for patients with cardiac arrest. Conventional Basic Life Support (BLS) training results in suboptimal CPR competency and skill retention. We aimed to compare the effectiveness of distributed CPR training with real-time feedback to conventional BLS training for CPR skills in pediatric healthcare providers.

The learning process of gait retraining using real-time feedback in patients with medial knee osteoarthritis.

The objective of this study was to investigate the learning process of knee osteoarthritis (KOA) patients learning to change their foot progression angle (FPA) over a six-week toe-in gait training program. Sixteen patients with medial KOA completed a six-week toe-in gait training program with real-time biofeedback. Patients walked on an instrumented treadmill while receiving real-time feedback on their foot progression angle (FPA) with reference to a target angle. The FPA difference (difference between targ...

Real-Time Feedback Control of Twin-Screw Wet Granulation based on Image Analysis.

The present paper reports the first dynamic image analysis-based feedback control of continuous twin-screw wet granulation process. Granulation of the blend of lactose and starch was selected as a model process. The size and size distribution of the obtained particles were successfully monitored by a process camera coupled with an image analysis software developed by the authors. The validation of the developed system showed that the particle size analysis tool can determine the size of the granules with an...

Virtual cerebral aneurysm clipping with real-time haptic force feedback in neurosurgical education.

Realistic, safe and efficient modalities for simulation-based training are highly warranted to enhance the quality of surgical education and should be incorporated in resident training. The aim of this study was to develop a patient-specific virtual cerebral aneurysm-clipping simulator with haptic force-feedback and real-time deformation of the aneurysm and vessels.

Behavioral and neural effects of congruency of visual feedback during short-term motor learning.

Visual feedback can facilitate or interfere with movement execution. Here, we describe behavioral and neural mechanisms by which the congruency of visual feedback during physical practice of a motor skill modulates subsequent performance gains. 18 healthy subjects learned to execute rapid sequences of right hand finger movements during fMRI scans either with or without visual feedback. Feedback consisted of a real-time, movement-based display of virtual hands that was either congruent (right virtual hand mo...

Consistency and similarity of MEG- and fMRI-signal time courses during movie viewing.

Movie-viewing allows human perception and cognition to be studied in complex, real-life-like situations in a brain-imaging laboratory. Previous studies with functional magnetic resonance imaging (fMRI) and with magneto- and electroencephalography (MEG/EEG) have demonstrated consistent temporal dynamics of brain activity across movie viewers. However, little is known about the similarities and differences of fMRI and MEG/EEG dynamics during such naturalistic situations. We thus compared MEG and fMRI response...

When compliments don't hit but critiques do: an fMRI study into self-esteem and self-knowledge in processing social feedback.

The way we view ourselves may play an important role in our responses to interpersonal interactions. In this study, we investigate how feedback valence, consistency of feedback with self-knowledge and global self-esteem influence affective and neural responses to social feedback.

Improving the signal detection accuracy of functional Magnetic Resonance Imaging.

A major drawback of functional Magnetic Resonance Imaging (fMRI) concerns the lack of detection accuracy of the measured signal. Although this limitation stems in part from the neuro-vascular nature of the fMRI signal, it also reflects particular methodological decisions in the fMRI data analysis pathway. Here we show that the signal detection accuracy of fMRI is affected by the specific way in which whole-brain volumes are created from individually acquired brain slices, and by the method of statistically ...

Suppression of vocal responses to auditory perturbation with real-time visual feedback.

Speakers can adjust pitch using auditory feedback through a short-latency corrective response known as the pitch-shift response (PSR). Suppression of the PSR denotes on-line stabilization of pitch. In this paper, the hypothesis that pitch-shift responses can be suppressed with real-time visual feedback of vocal F0 is investigated. Mandarin speakers and naive speakers without tonal language experience were instructed to produce the sustained vowel /a/ and Mandarin tone /ma1/ in an audio-only condition and a ...

IoT-based Remote Pain Monitoring System: from Device to Cloud Platform.

Facial expressions are among behavioral signs of pain that can be employed as an entry point to develop an automatic human pain assessment tool. Such a tool can be an alternative to the self-report method and particularly serve patients who are unable to self-report like patients in the Intensive Care Unit and minors. In this paper, a wearable device with a bio-sensing facial mask is proposed to monitor pain intensity of a patient by utilizing facial surface electromyogram (sEMG). The wearable device works ...

Adaptive heart rate-based epileptic seizure detection using real-time user feedback.

Automated seizure detection in a home environment has been of increased interest the last couple of decades. Heart rate-based seizure detection is a way to detect temporal lobe epilepsy seizures at home, but patient-independent algorithms showed to be insufficiently accurate due to the high patient-dependency of heart rate features. Therefore a real-time adaptive seizure detection algorithm is proposed here. The algorithm starts as a patient-independent algorithm, but gradually converges towards a patient-s...

A Noninvasive Brain-Computer Interface for Real-Time Speech Synthesis: The Importance of Multimodal Feedback.

We conducted a study of a motor imagery brain-computer interface (BCI) using electroencephalography to continuously control a formant frequency speech synthesizer with instantaneous auditory and visual feedback. Over a three-session training period, sixteen participants learned to control the BCI for production of three vowel sounds (/ textipa i/ [heed], / textipa A/ [hot], and / textipa u/ [who'd]) and were split into three groups: those receiving unimodal auditory feedback of synthesized speech, those rec...

Study on real-time force feedback for a master-slave interventional surgical robotic system.

In robot-assisted catheterization, haptic feedback is important, but is currently lacking. In addition, conventional interventional surgical robotic systems typically employ a master-slave architecture with an open-loop force feedback, which results in inaccurate control. We develop herein a novel real-time master-slave (RTMS) interventional surgical robotic system with a closed-loop force feedback that allows a surgeon to sense the true force during remote operation, provide adequate haptic feedback, and i...

Development of an isothermal amplification-based assay for the rapid detection of Cronobacter spp.

Cronobacter spp. is an opportunistic pathogen that is associated with rare but life-threatening neonatal infections resulting from the consumption of contaminated powdered infant formula milk (PIF). In the present study, we developed recombinase polymerase amplification (RPA) and real-time RPA for the detection of Cronobacter spp. in PIF for the first time by targeting the ompA gene. The specificity and sensitivity of the RPA and real-time RPA were validated and the practical applicability of these methods ...

Adding vibrotactile feedback to a myoelectric-controlled hand improves performance when online visual feedback is disturbed.

We investigated whether adding vibrotactile feedback to a myoelectric-controlled hand, when visual feedback is disturbed, can improve performance during a functional test. For this purpose, able-bodied subjects, activating a myoelectric-controlled hand attached to their right hand performed the modified Box & Blocks test, grasping and manipulating wooden blocks over a partition. This was performed in 3 conditions, using a repeated-measures design: in full light, in a dark room where visual feedback was dist...

Measuring Brain Connectivity via Shape Analysis of fMRI Time Courses and Spectra.

We present a shape matching approach for functional magnetic resonance imaging (fMRI) time course and spectral alignment. We use ideas from differential geometry and functional data analysis to define a functional representation for fMRI signals. The space of fMRI functions is then equipped with a reparameterization invariant Riemannian metric that enables elastic alignment of both amplitude and phase of the fMRI time courses as well as their power spectral densities. Experimental results show significant i...

Real-Time Closed Loop Diastolic Interval Control Prevents Cardiac Alternans in Isolated Whole Rabbit Hearts.

Cardiac alternans, a beat-to-beat alternation in action potential duration (APD), can lead to fatal arrhythmias. During periodic pacing, changes in diastolic interval (DI) depend on subsequent changes in APD, thus enhancing cardiac instabilities through a 'feedback' mechanism. Recently, an anti-arrhythmic Constant DI pacing protocol was proposed and shown to be effective in suppressing alternans in 0D and 1D in silico studies. However, previous experimental validation of Constant DI pacing in the heart ha...

Individual differences in learning correlate with modulation of brain activity induced by transcranial direct current stimulation.

Transcranial direct current stimulation (tDCS) has been shown to enhance cognitive performance on a variety of tasks. It is hypothesized that tDCS enhances performance by affecting task related cortical excitability changes in networks underlying or connected to the site of stimulation facilitating long term potentiation. However, many recent studies have called into question the reliability and efficacy of tDCS to induce modulatory changes in brain activity. In this study, our goal is to investigate the in...

Detection of Intravascular Injection During Cervical Transforaminal Epidural Injection: A Comparison of Digital Subtraction Angiography and Real Time Fluoroscopy.

Transforaminal epidural injection (TFEI) with local anesthetics and steroids are effective in treating spinal radicular pain. However, inadvertent intravascular injection can lead to severe neurologic complications. To reduce complications of intravascular injection, use of imaging modality, such as real-time fluoroscopy (RTF) or digital subtraction angiography (DSA), has been recommended. DSA is an imaging technique that can clearly visualize the blood vessels from surrounding bones or dense soft tissues b...
