“…LBP represents a relevant socio-economic burden as is responsible for the exploitation of the National Health Service and absenteeism in workplaces [ 6 , 7 ]. Many contactless and contact-based devices for ROMs detection are available on the market [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ], but most of them are bulky, invasive or uneasy to wear during the working hours. In the last decades, the advantages brought by FOSs (i.e., flexibility, lightness, handling and multiplexing capability [ 22 , 23 ]) led to the increasing use of FOSs-based wearable devices [ 22 , 23 , 24 ].…”

“…In the literature, lumbar ROMs has been detected using a wide range of devices based on non-wearable (i.e., goniometers [ 12 ] and MoCap systems [ 14 ]) and wearable (i.e., MEMS accelerometers and piezoresistive textiles [ 16 ], strain gauge sensors [ 17 ], and FOSs-based systems [ 18 , 19 , 20 ]) technologies.…”

“…Focusing on wearable solutions, different technologies have been proposed. A hybrid system based on piezoresistive and MEMS technology integrated into a rowing [ 16 ] and a sensing solution composed by two flexible stripes embedding 12 strain gauge (Epionics SPINE system) [ 17 ] were presented. In both the studies a MoCap system was used as a benchmark to assess the capability in detecting F/E.…”

“…In both the studies a MoCap system was used as a benchmark to assess the capability in detecting F/E. The system in [ 16 ] was tested only on a single volunteer during six trials of F/E showing a 2% error in length estimation when compared with a MoCap system, while the one in [ 17 ] was tested on 20 volunteers to monitor lumbar ROMs during standing, walking, running, and sitting, showing moderate agreement with the benchmark. Both the systems are bulky due to the presence of multiple cables and additional tools (i.e., MEMS placed on the sacrum and the T12 thoracic vertebra [ 16 ], and a portable storage unit fixed to a belt [ 17 ]).…”

“…Although accurate, such systems prove to be cumbersome or uncomfortable to use during the whole working day. Therefore, to overcome these limits, the technology has increasingly moved towards the development of lightweight and wearable devices such as the ones embedding inertial sensors and piezoresistive textiles [ 16 ], strain gauge sensors [ 17 ] or fiber optic sensors (FOSs) [ 18 , 19 , 20 ]. In particular, in the last twenty years FOSs played a crucial role in the implementation of compact wearables able to monitor spinal ROMs thanks to the properties of such technology (i.e., flexibility, lightness, handling, and multiplexing capability [ 21 , 22 , 23 ]).…”

Low back pain (LBP) is one of the musculoskeletal disorders that most affects workers. Among others, one of the working categories which mainly experiences such disease are video terminal workers. As it causes exploitation of the National Health Service and absenteeism in workplaces, LBP constitutes a relevant socio-economic burden. In such a scenario, a prompt detection of wrong seating postures can be useful to prevent the occurrence of this disorder. To date, many tools capable of monitoring the spinal range of motions (ROMs) are marketed, but most of them are unusable in working environments due to their bulkiness, discomfort and invasiveness. In the last decades, fiber optic sensors have made their mark allowing the creation of light and compact wearable systems. In this study, a novel wearable device embedding a Fiber Bragg Grating sensor for the detection of lumbar flexion-extensions (F/E) in seated subjects is proposed. At first, the manufacturing process of the sensing element was shown together with its mechanical characterization, that shows linear response to strain with a high correlation coefficient (R2 > 0.99) and a sensitivity value (Sε) of 0.20 nm∙mε−1. Then, the capability of the wearable device in measuring F/E in the sagittal body plane was experimentally assessed on a small population of volunteers, using a Motion Capture system (MoCap) as gold standard showing good ability of the system to match the lumbar F/E trend in time. Additionally, the lumbar ROMs were evaluated in terms of intervertebral lumbar distances (Δ d L 3 − L 1 ) and angles, exhibiting moderate to good agreement with the MoCap outputs (the maximum Mean Absolute Error obtained is ~16% in detecting Δ d L 3 − L 1 ). The proposed wearable device is the first attempt for the development of FBG-based wearable systems for workers’ safety monitoring.

Biomechanical analysis of the human spine is crucial to understanding injury patterns. Motion capture technology has gained attention due to its non-invasive nature. Nevertheless, traditional motion capture studies consider the spine a single rigid segment, although its alignment changes during movement. Moreover, guidelines that indicate where markers should be placed for a specific exercise do not exist. This study aims to review the methods used to assess spine biomechanics using motion capture systems to determine the marker sets used, the protocols used, the resulting parameters, the analysed activities, and the characteristics of the studied populations. PRISMA guidelines were used to perform a Scoping Review using SCOPUS and Web of Science databases. Fifty-six journal and conference articles from 1997 to 2023 were considered for the analysis. This review showed that Plug-in-Gait is the most used marker set. The lumbar spine is the segment that generates the most interest because of its high mobility and function as a weight supporter. Furthermore, angular position and velocity are the most common outcomes when studying the spine. Walking, standing, and range of movement were the most studied activities compared to sports and work-related activities. Male and female participants were recruited similarly across all included articles. This review presents the motion capture techniques and measurement outcomes of biomechanical studies of the human spine, to help standardize the field. This work also discusses trends in marker sets, study outcomes, studied segments and segmentation approaches. Graphical Abstract
