Effects of the Digital Transformation: Qualitative Study on the Disturbances and Limitations of Using Video Visits in Outpatient Care.

BACKGROUND: Video mediated meetings with patients were introduced in outpatient care at a hospital in Sweden. New behaviours and tasks emerged due to changes of roles, work processes and responsibilities. The study investigates effects of digital transformation, in this case how video visits in outpatient care change work processes and introduces new tasks, in order to further improve the concept of video visits. OBJECTIVE: Through real-time, social interactional features of preparing for and conducting video visits, the study examines clinicians' perceived limitations and disturbances, and how the conditions between patients and clinicians may change when using video visits instead of face-to-face meetings in outpatient care. METHODS: Qualitative methods have been used including 14 observations of video visits at two different clinics and 14 followup interviews with clinicians. Transcriptions of interviews and field notes were thematically analysed, discussed and synthesised into themes. RESULTS: Disturbances and limitations related to the technology were related to time; a flexibility to schedule the meeting unbound of place, frustrations when the other part was late for the scheduled meeting, and that more experienced users of video visits usually waited longer before logging in. They were also related to sound; problems getting the sound to work satisfactory during the video visits, and problems with the image. Disturbances and limitations related to the surroundings were related to both the patient's and the clinician's environment; the principle of video technology in itself may affect the experience and the content of the consultation, and the surrounding chosen changes the conditions for and reduces the participants' field of view. CONCLUSIONS: We could see 1) a transformation of roles and responsibilities when turning from face-to-face meetings to video visits, 2) that video visits add new circumstances, with a risk of introducing disturbances and limitations, that in turn affects the content of the meeting, 3) that avoiding negative disturbances during a video visit, requires a sensibility from the clinician's side as well as a trust in the patient's judgement, 4) that both expected and unexpected disturbances and limitations during a video visit affect the clinician's behaviour, feelings, the content of the meeting and how the clinician's relate to the different components of the concept, and 5) that there is a change of roles introduced when conducting video visits, eg, the clinician taking the first line support if both (s)he and the patient encounter problems with the technology.

A comparison of animated versus static images in an instructional multimedia presentation.

Sophisticated three-dimensional animation and video compositing software enables the creation of complex multimedia instructional movies. However, if the design of such presentations does not take account of cognitive load and multimedia theories, then their effectiveness as learning aids will be compromised. We investigated the use of animated images versus still images by creating two versions of a 4-min multimedia presentation on vascular neuroeffector transmission. One version comprised narration and animations, whereas the other animation comprised narration and still images. Fifty-four undergraduate students from level 3 pharmacology and physiology undergraduate degrees participated. Half of the students watched the full animation, and the other half watched the stills only. Students watched the presentation once and then answered a short essay question. Answers were coded and marked blind. The "animation" group scored 3.7 (SE: 0.4; out of 11), whereas the "stills" group scored 3.2 (SE: 0.5). The difference was not statistically significant. Further analysis of bonus marks, awarded for appropriate terminology use, detected a significant difference in one class (pharmacology) who scored 0.6 (SE: 0.2) versus 0.1 (SE: 0.1) for the animation versus stills group, respectively (P = 0.04). However, when combined with the physiology group, the significance disappeared. Feedback from students was extremely positive and identified four main themes of interest. In conclusion, while increasing student satisfaction, we do not find strong evidence in favor of animated images over still images in this particular format. We also discuss the study design and offer suggestions for further investigations of this type.

Comparative intralimb coordination in avian bipedal locomotion.

Analyses of how intralimb coordination during locomotion varies within and across different taxa are necessary for understanding the morphological and neurological basis for locomotion in general. Previous findings suggest that intralimb proportions are the major source of kinematic variation that governs intralimb coordination across taxa. Also, independence of kinematics from habitat preference and phylogenetic position has been suggested for mammals. This leads to the hypothesis that among equally sized bird species exhibiting equal limb proportions, similar kinematics can be observed. To test this hypothesis, the bipedal locomotion of two distantly related ground-dwelling bird species (Eudromia elegans and Coturnix coturnix) and of a less terrestrial species (Corvus monedula) was investigated by means of a biplanar high-speed X-ray videographic analysis. Birds exhibited similar intralimb proportions and were filmed over a broad range of speed while moving on a treadmill. Joint and limb element angles, as well as pelvic rotations, were quantified. Regarding fore-aft motions of the limb joints and elements, a congruent pattern of intralimb coordination was observed among all experimental species. The sample of species suggests that this is largely independent of their habitat preference and systematic position and seems to be related to demands for coping with an irregular terrain with a minimum of necessary control. Hence, the initial hypothesis was confirmed. However, this congruence is not found when looking at medio-lateral limb motions and pelvic rotations, showing distinct differences between ground-dwellers (e.g. largely restricted to a parasagittal plane) and C. monedula (e.g. increased mobility of the hip joint).

Toe function and dynamic pressure distribution in ostrich locomotion.

The ostrich is highly specialized in terrestrial locomotion and is the only extant bird that is both didactyl and exhibits a permanently elevated metatarsophalangeal joint. This extreme degree of digitigrady provides an excellent opportunity for the study of phalangeal adaptation towards fast, sustained bipedal locomotion. Data were gathered in a semi-natural setting with hand-raised, cooperative specimens. Dynamic pressure distribution, centre of pressure (CoP) trajectory and the positional inter-relationship of the toes during stance phase were investigated using pedobarography. Walking and running trials shared a J-shaped CoP trajectory with greater localization of CoP origin as speed increased. Slight variations of 4th toe position in walking affect CoP origin and modulation of 4th toe pressure on the substrate allows correction of balance, primarily at the beginning of stance phase at lower speeds. Load distribution patterns differed significantly between slow and fast trials. In walking, the 3rd and particularly the 4th toe exhibited notable variation in load distribution with minor claw participation only at push-off. Running trials yielded a distinctly triangular load distribution pattern defined by the 4th toe tip, the proximal part of the 3rd toe and the claw tip, with the sharp point of the claw providing an essential traction element at push-off. Consistency of CoP trajectory and load distribution at higher speeds arises from dynamic stability effects and may also reflect stringent limitations to degrees of freedom in hindlimb joint articulation that contribute to locomotor efficiency. This novel research could aid in the reconstruction of theropod locomotor modes and offers a systemic approach for future avian pedobarographic investigations.

Indocyanin green videoangiography study of hemangioblastomas.

OBJECTIVE: We present herein the intraoperative indocyanin green videoangiography (ICGVAG) findings for three cases of cerebellar hemangioblastoma (HB). CASES: Cerebellar HB was detected in three patients presenting with symptoms of vertigo and/or headaches and diagnosed on the basis of preoperative magnetic resonance imaging (MRI) and cerebral angiographic findings. Preoperative embolization of the tumor feeding artery was not performed in any of the patients. None of the patients underwent any procedure prior to ICGVAG that would affect the ICG findings, such as perilesional hemostatic coagulation or ablation. In each patient, it was possible to judge the approximate location of the tumor in relation to the brain surface and to distinguish the feeding and draining vessels. Following resection of the tumor, ICGVAG images confirmed that the mural nodule had been eliminated. None of the patients required blood transfusion, either during or after the surgery. For each patient, the lesion was pathologically confirmed as HB, postoperative contrast-enhanced MRI confirmed the absence of residual tumor, and diffusion-weighted MRI revealed no ischemic changes. RESULTS: Differentiation of feeding and draining vessels in the region of the lesion is particularly important for successful surgical removal of HB. In the present three patients, ICGVAG findings enabled easy vascular differentiation and were also useful for confirming that there was no residual tumor. Indocyanin green videoangiography was concluded to be useful for safe resection of HB.

Application of intraoperative indocyanine green angiography for CNS tumors: results on the first 100 cases.

PURPOSE: To investigate the application of indocyanine green (ICG) videoangiography during microsurgery for central nervous system (CNS) tumors. METHODS: One hundred patients with CNS tumors who underwent microsurgical resection from December 2006 to December 2008 were retrospectively analyzed. The diagnosis was high grade glioma in 54 cases, low grade in 17 cases, meningioma in 14 cases, metastasis in 12 cases and hemangioblastoma in 3 cases. Overall, ICG was injected intraoperatively 194 times. The standard dose of 25mg of dye was injected intravenously and intravascular fluorescence from within the blood vessels was imaged through an ad hoc microscope with dedicated software (Pentero, Carl Zeiss Co., Oberkochen, Germany). Pre-resection and post-resection arterial, capillary and venous ICG videoangiographic phases were intraoperatively observed and recorded. RESULTS: ICG videangiography allowed for a good evaluation of blood flow in the tumoral and peritumoral exposed vessels in all cases. No side effects due to ICG were observed. CONCLUSIONS: ICG video-angiography is a significant method for monitoring blood flow in the exposed vessels during microsurgical removal of CNS tumors. Pre-resection videoangiography provides useful information on the tumoral circulation and the pathology-induced alteration in surrounding brain circulation. Post-resection examination allows for an immediate check of patency of those vessels that are closely related to the tumor mass and that the surgeon does not want to damage.

Automated image analysis for the detection of benthic crustaceans and bacterial mat coverage using the VENUS undersea cabled network.

The development and deployment of sensors for undersea cabled observatories is presently biased toward the measurement of habitat variables, while sensor technologies for biological community characterization through species identification and individual counting are less common. The VENUS cabled multisensory network (Vancouver Island, Canada) deploys seafloor camera systems at several sites. Our objective in this study was to implement new automated image analysis protocols for the recognition and counting of benthic decapods (i.e., the galatheid squat lobster, Munida quadrispina), as well as for the evaluation of changes in bacterial mat coverage (i.e., Beggiatoa spp.), using a camera deployed in Saanich Inlet (103 m depth). For the counting of Munida we remotely acquired 100 digital photos at hourly intervals from 2 to 6 December 2009. In the case of bacterial mat coverage estimation, images were taken from 2 to 8 December 2009 at the same time frequency. The automated image analysis protocols for both study cases were created in MatLab 7.1. Automation for Munida counting incorporated the combination of both filtering and background correction (Median- and Top-Hat Filters) with Euclidean Distances (ED) on Red-Green-Blue (RGB) channels. The Scale-Invariant Feature Transform (SIFT) features and Fourier Descriptors (FD) of tracked objects were then extracted. Animal classifications were carried out with the tools of morphometric multivariate statistic (i.e., Partial Least Square Discriminant Analysis; PLSDA) on Mean RGB (RGBv) value for each object and Fourier Descriptors (RGBv+FD) matrices plus SIFT and ED. The SIFT approach returned the better results. Higher percentages of images were correctly classified and lower misclassification errors (an animal is present but not detected) occurred. In contrast, RGBv+FD and ED resulted in a high incidence of records being generated for non-present animals. Bacterial mat coverage was estimated in terms of Percent Coverage and Fractal Dimension. A constant Region of Interest (ROI) was defined and background extraction by a Gaussian Blurring Filter was performed. Image subtraction within ROI was followed by the sum of the RGB channels matrices. Percent Coverage was calculated on the resulting image. Fractal Dimension was estimated using the box-counting method. The images were then resized to a dimension in pixels equal to a power of 2, allowing subdivision into sub-multiple quadrants. In comparisons of manual and automated Percent Coverage and Fractal Dimension estimates, the former showed an overestimation tendency for both parameters. The primary limitations on the automatic analysis of benthic images were habitat variations in sediment texture and water column turbidity. The application of filters for background corrections is a required preliminary step for the efficient recognition of animals and bacterial mat patches.

Application of microscope integrated indocyanine green video-angiography during microneurosurgical treatment of intracranial aneurysms: a review.

Indocyanine Green Video Angiography (ICG-VA) is recently introduced to the practice of cerebrovascular neurosurgery. This technique is safe and noninvasive and provides reliable real-time information on the patency of blood vessels of any size, as well as residual filling of aneurysms. In this article, a review of the literature and our experience with ICG-VA during microneurosurgery of intracranial aneurysms is presented.

Video-Based Motion Analysis Use: A National Survey of Orthopedic Physical Therapists.

OBJECTIVES: Motion analysis is performed by physical therapists to assess and improve movement. Two-dimensional video-based motion analysis (VBMA) is available for smartphones/tablets and requires little to no equipment or cost. Research on VBMA use in clinical practice is limited. The purpose of this study was to examine the current use of VBMA in orthopedic physical therapist practice. METHODS: Members of the Academy of Orthopaedic Physical Therapy completed an online survey. Questions examined frequency of VBMA use, reasons for use, facilitators/barriers, device/apps used, practice patterns, other certificates/degrees, and demographic information. RESULTS: Among the final analysis sample of 477 respondents, 228 (47.8%) use VBMA. Of 228 VBMA users, 91.2% reported using it for ≤25% of their caseload, and 57.9% reported using their personal device to capture movement. Reasons for using VBMA included visual feedback for patient education (91.7%), analysis of movement (91.2%), and assessment of progress (51.8%). Barriers to use included lack of device/equipment (48.8%), lack of space (48.6%), and time restraint (32.1%). Those with ≤20 years of clinical experience (odds ratio [OR] = 1.83, 95% CI = 1.21-2.76), residency training (OR = 2.49, 95% CI = 1.14-5.43), and fellowship training (OR = 2.97, 95% CI = 1.32-6.66), and those from the West region of the United States (OR = 1.66, 95% CI = 1.07-2.56) were more likely to use VBMA. CONCLUSIONS: More than 50% of surveyed orthopedic physical therapists do not use VBMA in clinical practice. Future research should be directed toward assessing reliability and validity of VBMA use by smartphones, tablets, and apps and examining whether VBMA use enhances treatment outcomes. Data security, patient confidentiality, and integration into the electronic medical record should be addressed. IMPACT: This study is the first to our knowledge to describe the use of VBMA in orthopedic physical therapist practice in the United States. It is the first step in understanding how VBMA is used and might be used to enhance clinical assessment and treatment outcomes.

A comparative analysis using flowmeter, laser-Doppler |spectrophotometry, and indocyanine green-videoangiography for detection of vascular stenosis in free flaps.

The effects of gradual vascular occlusion on the blood supply of perfused areas are poorly described. Information relating to the comparison of flap monitoring techniques is lacking. Varying stenotic conditions (0%, 25%, 50%, 75% and 100%) were generated on purpose at the A. and V. femoralis in the rat model. Analyses included flowmeter, simultaneous laser-Doppler flowmetry and tissue spectrophotometry (O2C) and indocyanine green- (ICG-) videoangiography with integrated FLOW 800 tool. A Random Forests prediction model was used to analyse the importance of each method to diagnose the stenotic conditions. The ability to discriminate and to accurately estimate the probability of stenosis was assessed by Receiver Operating Characteristic (ROC) curves and calibration plots. Blood flow changes for all modalities were described in detail. Flowmeter displayed earliest a linear decrease as a result of increasing stenosis. A stenosis of 50% degrees was most difficult to detect correctly. The combination of flowmeter and ICG-videoangiography showed high diagnostic power for each stenotic situation (area under the ROC > 0.79). Flowmeter and ICG-videoangiography showed to be most relevant in detection of varying stenotic conditions and may change the clinical outcome. The O2C showed less effect on varying stenotic situations as the only surface monitoring device.

Low-Cost Active Thermography using Cellphone Infrared Cameras: from Early Detection of Dental Caries to Quantification of THC in Oral Fluid.

Active thermography (AT) is a widely studied non-destructive testing method for the characterization and evaluation of biological and industrial materials. Despite its broad range of potential applications, commercialization and wide-spread adaption of AT has long been impeded by the cost and size of infrared (IR) cameras. In this paper, we demonstrate that this cost and size limitation can be overcome using cell-phone attachment IR cameras. A software development kit (SDK) is developed that controls camera attributes through a simple USB interface and acquires camera frames at a constant frame rate up to 33 fps. To demonstrate the performance of our low-cost AT system, we report and discuss our experimental results on two high impact potential applications. The first set of experiments is conducted on a dental sample to investigate the clinical potential of the developed low-cost technology for detecting early dental caries, while the second set of experiments is conducted on the oral-fluid based lateral flow immunoassay to determine the viability of our technology for detecting and quantifying cannabis consumption at the point-of-care. Our results suggest achievement of reliable performance in the low-cost platform, comparable to those of costly and bulky research-grade systems, paving the way for translation of AT techniques to market.

Effect of a preoperative instructional digital video disc on patient knowledge and preparedness for engaging in postoperative care activities.

This project determined the effects of developing and implementing a preoperative instructional digital video disc (DVD) on patients' level of knowledge, preparedness, and perceived ability to participate in postoperative care activities. Content areas that were incorporated into the preoperative instructional DVD included: pain management, surgical drainage, vital signs, incentive spirometry, cough and deep breathe, chest physiotherapy, anti-embolism stockings/sequential compression device, ambulation, diet/bowel activity/urine output, and discharge. A system was created to ensure that patients consistently received the preoperative instructional DVD prior to surgery. The instructional media product was found to be effective in increasing pre-operative knowledge and preparedness of patients and their families. Nurses reported higher levels of knowledge and engagement among patients and their families related to postoperative activities.

Object recognition analysis in mice using nose-point digital video tracking.

Preferential exploration of novel locations and objects by rodents has been used to test the effects of various manipulations on object recognition memory. However, manual scoring is time-consuming, requires extensive training, and is subject to inter-observer variability. Since rodents explore primarily by sniffing, we assessed the ability of new nose-point video tracking software (NPVT) to automatically collect object recognition data. Mice performed a novel object/novel location task and data collected by NPVT, two expert observers, and one inexperienced observer were compared. Percent time spent exploring the objects were correlated between the two expert observers and between NPVT and the two expert observers. In contrast, the inexperienced observer showed no correlation with either expert observer or NPVT. NPVT collected more reliable data compared to the inexperienced observer. NPVT and the expert observers gave similar group averages for arbitrarily assigned groups of mice, whereas the analysis of the inexperienced observer gave different results. Finally, NPVT generated valid results in a NO/NL experiment comparing mice expressing human apolipoprotein E3 versus E4, a risk factor for age-related cognitive decline. Video tracking with nose-point detection generates useful analyses of rodent object recognition task performance and possibly for other behavioral tests.

Real-time teleophthalmology video consultation: an analysis of patient satisfaction in rural Western Australia.

BACKGROUND: Teleophthalmology, particularly real-time video consultation, holds great potential in Australia and similar countries worldwide, where geography, population and medical workforce distribution make it difficult to provide specialist eye services outside of major cities. Assessment and referrals from rural optometrists are vital to the success of teleophthalmology. While there is good evidence for the efficacy of such services, there is limited evidence for patient satisfaction with video consultation. METHODS: To evaluate patient satisfaction with teleophthalmology, the current study recruited patients who underwent a video consultation with Lions Outback Vision, for a follow-up telephone-based questionnaire assessing satisfaction. Regression analysis was performed assessing which demographic features and which features of the video consultation itself were associated with highest overall satisfaction. RESULTS: One hundred and nine of the 137 eligible patients completed the questionnaire (79.6 per cent; 55 per cent male; mean age 64.61 years). The majority of the participants were either 'Very satisfied' (69.1 per cent) or 'Satisfied' (24.5 per cent) with the service. No one reported being either 'Dissatisfied' or 'Very dissatisfied'. Linear regression did not reveal any demographic or follow-up variables as predictive of greater total satisfaction; however, participants who were older, felt they could easily explain their medical problems to the doctor in the video consultation and believed that telemedicine enabled them to save money and time, and were more likely to report higher overall satisfaction. CONCLUSION: Teleophthalmology is a promising new way to overcome barriers to the delivery of eye care services to rural and remote populations. This study demonstrates a high level of overall satisfaction with teleophthalmological video consultation and patients are accepting of this emerging consultation modality, regardless of age.

Differentiating between benign and less benign: epilepsy surgery in symptomatic frontal lobe epilepsy associated with benign focal epileptiform discharges of childhood.

Benign focal epileptiform discharges of childhood are a genetically determined electroencephalographic trait. Assessment of their clinical relevance in children with epilepsy may be difficult if imaging reveals a lesion congruent or incongruous with the focus of the benign focal epileptiform discharges of childhood. This article reports a boy with parietooccipital benign focal epileptiform discharges of childhood in whom videoelectroencephalography and magnetic resonance imaging disclosed symptomatic frontal lobe epilepsy. Surgical removal of a focal cortical dysplasia in the left frontal lobe yielded freedom from seizures and positive behavioral and cognitive development. Nocturnal benign focal epileptiform discharges of childhood persisted until puberty (follow-up, 50 months). Early diagnostic differentiation of idiopathic syndromes such as idiopathic benign focal epilepsy of childhood from symptomatic focal epilepsies with a potentially less benign course is important. In symptomatic frontal lobe epilepsy, epilepsy surgery may yield an excellent outcome despite the presence of concurrent benign focal epileptiform discharges of childhood.

Portable MP3 players: innovative devices for recording qualitative interviews.

Digital technology has provided a new way of recording qualitative interviews, surpassing the clarity, usability and storage capabilities of conventional tape recorders. Ritin Fernandez and Rhonda Griffiths examine a technological resource that pervades modern social life and which can be used effectively for digitally recording interviews for qualitative research.

Innovative interactive videodisc units for teaching of pathology laboratory cases. Five years' experience.

Seven computer-assisted interactive videodisc instruction units, based on laboratory cases in the General Pathology course for first-year medical students, were developed. Images from the laser videodisc Slice of Life, contributed previously by one of the authors, and the program "Hypercard stack 2.1" were used to develop these units to provide students with interactive software for independent supplemental review of the laboratory cases studied in the course. With the dual-screen system developed, specific picture frames from the videodisc are retrieved on one screen while the other screen displays the corresponding text. The seven units include two units each on cell injury, inflammation, and neoplasia, and one on opportunistic infections. Each unit contains several case studies, each of which consists of the following: a clinical profile, gross pictures and description of the tissue removed, sequential photomicrographs at successively higher magnifications from various fields of tissue slides and their descriptions, comparison with normal histology of the organ involved, interpretation of the observations and comments, final diagnosis, and a quiz. The histopathologic features are specifically emphasized with programmed, computer-generated pointers to indicate specific cells or structures on the images. Each case also contains a glossary to define terms not familiar to first-year students. Although no comparative performance data are available, evaluation of the units obtained from nine terms of use in the last 5 years indicates that these units are extremely valuable supplemental tools for students for independent review of the laboratory cases.

Propagation of tonic posturing in supplementary motor area (SMA) seizures.

We analyzed ictal motor symptoms in 10 patients diagnosed to have supplementary motor area (SMA) seizures based on ictal encephalographic (EEG) findings and ictal clinical semiology. Inclusion criteria were (1) EEG seizure pattern in the vertex for the scalp recording or in the area over and/or adjacent to SMA for epicortical recording and (2) ictal motor semiology characterized, as previously reported, by sudden and a brief tonic posturing of extremities and trunk mainly occurring during sleep without loss of consciousness. In 50% (5/10) of the patients, tonic posturing began in one part of the body and moved to other part(s) in 5-10s. Unlike Jacksonian march seen in seizures involving the primary sensorimotor area (S1-M1), it spread in no accordance with the somatotopy in S1-M1. The sequential propagation of tonic posturing may represent the somatotopic organization within the SMA proper.

Feasibility of using a video-based motion analysis system for measuring thumb kinematics.

While several different methods have been used to measure hand kinematics, fluoroscopy is generally considered to be the most accurate. Recently, video-based motion analysis has been developed for the measurement of joint kinematics. This method is versatile, easy to use, and can measure motions dynamically. Surface markers are most commonly used in the video-based motion systems. However, whether the surface markers placed on the thumb accurately represent the true kinematics of the underlying bony segment is questionable. In this study, the feasibility of surface markers to represent thumb kinematics was investigated by fluoroscopy. Both the positions of surface markers and bony landmarks were simultaneous recorded and then digitized. The Ra(2) values comparing the angular changes of the thumb interphalangeal, metacarpal and carpometacarpal joints derived using the surface markers or bony landmarks were 0.9986, 0.9730 and 0.9186 in the flexion/extension plane respectively, 0.8837, 0.9697 and 0.8775 in the abduction/adduction plane; and 0.9884, 0.9643 and 0.9431 in the opposition plane. The ranges, mean and standard deviation of the absolute differences between calculated angles of different marker sets were also compared. These data revealed that the similarities of the two different marker techniques throughout the motion cycle were high. The differences between the two methods were also within clinically allowable range of +/-5 degrees. It is concluded that the application of the video-based motion analysis system with surface markers to thumb kinematics is warranted.

Movement quantification in epileptic seizures: a new approach to video-EEG analysis.

It is common that epileptic seizures induce uncoordinated movement in a patient's body. This movement is a relevant clinical factor in seizure identification. Nevertheless, quantification of this information has not been an object of much attention from the scientific community. In this paper, we present our effort in developing a new approach to the quantification of movement patterns in patients during epileptic seizures. We attach markers at landmark points of a patient's body and use a camera and a commercial video-electroencephalogram (EEG) system to synchronously register EEG and video during seizures. Then, we apply image-processing techniques to analyze the video frames and extract the trajectories of those points that represent the course of the quantified movement of different body parts. This information may help clinicians in seizure classification. We describe the framework of our system and a method of analyzing video in order to achieve the proposed goal. Our experimental results show that our method can reflect quantified motion patterns of epileptic seizures, which cannot be accessed by means of traditional visual inspection of video recordings. We were able, for the first time, to quantify the movement of different parts of a convulsive human body in the course of an epileptic seizure. This result represents an enhanced value to clinicians in studying seizures for reaching a diagnosis.
