“… 26 In numerous prior virtual reality simulations, body positions and movements often deviated from real-life experiences, such as when encountering a roller coaster ride. 27 Comparatively, in this simulation, although complete elimination was not possible due to the inherent limitations of virtual reality, the incidence of cybersickness was mitigated by aligning the user’s movement direction, behaviors, and hand placement. Further research on the effectiveness of this type of simulator in reducing motion sickness is encouraged for clearer conclusions.…”

Purpose The aim of this prospective study was to develop a virtual reality simulator (VRS) for spinal cord stimulation (SCS) trials and establish its effectiveness. Methods We developed a VRS for SCS training by integrating patient imaging data analytics, creating artificial X-ray images, and using spatial alignment techniques and virtual reality technologies. The simulator was created by a physician with considerable experience in performing SCS, and can simulate the feeling of the procedure in a virtual environment. The efficacy of the simulator for SCS trials was assessed using a cohort of 20 novice trainees. The primary outcomes were duration of the procedure, checklist score, number of C-arm images captured, and overall trainee satisfaction. Results The cohort that utilized the VRS had better Zwisch scale scores (P <0.001), completed the procedure in a shorter time (P <0.001), took fewer C-arm images (P <0.001), and reported better overall satisfaction (P = 0.011) than the cohort that did not. Conclusion We developed a realistic and efficient VRS for educating novice trainees on SCS trials, thereby eliminating the risk of radiation exposure associated with cadaver training. The results of this study indicate that our VRS has potential as an instrumental resource that can be integrated into the educational framework for SCS trials.

“…FOF is multidimensional in nature, encompassing various underlying constructs, such as fall-related concerns and fall efficacy, each requiring distinct measurement approaches 38. For this reason, the generalisation of results from studies using measurements of different constructs is quite complicated 39. Moreover, fall-related concerns are usually assessed through subjective self-perceived questionnaires,40 41 introducing the likelihood of systematic bias in results 42.…”

“…Developing objective assessment protocol for FOF can eliminate the bias in self-report and overcome other limitations. Real-time, synchronised, movement-based and objective physiological assessments of movement-related concerns are lacking 53 54. Most of the studies that were aiming to develop an objective measuring strategy for FOF with the help of VR to induce fear had different experimental setups, evaluated FOF during static positions (eg, sitting and standing)27 39 54 55 and were applied on population who do not have pathological conditions that might be disabling 27 39 54 55…”

BackgroundFalls are common in older people and individuals with neurological conditions. Parkinson’s disease (PD) is known for postural instability causing mobility disabilities, falls and reduced quality of life. The fear of falling (FOF), a natural response to unstable balance, can worsen postural control problems. Evaluating FOF relies largely on affected persons’ subjective accounts due to limited objective assessment methods available. The aim of this mixed-methods feasibility study is to develop an assessment method for FOF while in motion and walking within virtual environments. This study will assess a range of FOF-related responses, including cognitive factors, neuromuscular response and postural stability.Methods and analysisThis feasibility study will consist of four phases: the first two phases will include people without PD, while the other two will include people diagnosed with PD. Participants will be assessed for direct and indirect responses to real life, as well as virtual environment walking scenarios that may induce FOF. Data from questionnaires, different neurophysiological assessments, movement and gait parameters, alongside evaluations of usability and acceptability, will be collected. Semistructured interviews involving both participants and research assistants shall take place to elicit their experiences throughout different phases of the assessments undertaken. Demographic data, the scores of assessment scales, as well as feasibility, usability and acceptability of the measurement methods, will be illustrated via descriptive statistics. Movement and gait outcomes, together with neurophysiological data, will be extracted and calculated. Exploring relationships between different factors in the study will be achieved using a regression model. Thematic analysis will be the approach used to manage qualitative data.Ethics and disseminationThis feasibility study was approved by the Ethics Committee of the Faculty of Physical Therapy, Kafr El Sheikh University, Egypt (number: P.T/NEUR/3/2023/46). The results of this study will be published in a peer-reviewed journal.Trial registration numberClinicalTrials.gov Registry (NCT05931692).
