What this Trial Is About
Researchers are evaluating markerless gait analysis in adults with neuromuscular diseases or in asymptomatic volunteers. This study aims to improve monitoring of walking biomechanics, which current gait tests may not fully capture, especially given the slow progression of symptoms in these conditions. The study focuses on quantifying gait parameters using a portable digital device to allow for easier and effective assessment without complex equipment. Participants will walk with shoes in a gait analysis room while wearing VICON markers on their body. Simultaneously, two smartphones will record video to compare the traditional marker-based gait analysis with the markerless system using motion analysis software. All participants receive the same intervention involving walking and simultaneous recording for comparison. During the study, participants will be evaluated on how well the markerless system correlates with the VICON system on the first day. Researchers will collect data on walking biomechanics through the two methods. Participants must be able to walk and stand independently for certain periods and will be monitored for their ability to perform specific physical tasks. The study includes adults aged 18 to 65, both with neuromuscular diseases of genetic origin and without symptoms, with total participation lasting at least the assessment day.
