“…Recently, the development and the spread of Inertial Measurement Units (IMUs) for spatiotemporal and kinematic assessment has represented an innovative progress in the field of biomechanics and wearable sensors. Indeed, wearable sensors based on IMUs are spreading in the biomedical field showing good performances [ 89 , 90 , 91 ] compared to their gold standards. Moreover, considering that the working principle of IMUs is based on the measurement of inertia, IMUs can be applied anywhere without a reference [ 92 ] and integrated with textile technology [ 93 ].…”

The use of e-textile technologies spread out in the scientific research with several applications in both medical and nonmedical world. In particular, wearable technologies and miniature electronics devices were implemented and tested for medical research purposes. In this paper, a systematic review regarding the use of e-textile for clinical applications was conducted: the Scopus and Pubmed databases were investigate by considering research studies from 2010 to 2020. Overall, 262 papers were found, and 71 of them were included in the systematic review. Of the included studies, 63.4% focused on information and communication technology studies, while the other 36.6% focused on industrial bioengineering applications. Overall, 56.3% of the research was published as an article, while the remainder were conference papers. Papers included in the review were grouped by main aim into cardiological, muscular, physical medicine and orthopaedic, respiratory, and miscellaneous applications. The systematic review showed that there are several types of applications regarding e-textile in medicine and several devices were implemented as well; nevertheless, there is still a lack of validation studies on larger cohorts of subjects since the majority of the research only focuses on developing and testing the new device without considering a further extended validation.

“…Although in our study we did not use a Gold Standard system for the concurrent validity of the sensor, there are already studies in the literature in healthy and pathological populations that demonstrate its advantages and limitations compared to other measuring devices such as GAITRite® [21,26,27], optoelectronic motion capture system (mocap) [25] and other IMUs [47,48]. A recent systematic review and meta-analysis support the above results by highlighting good to excellent validity and reliability for time/step length and stride measures, however, spatiotemporal asymmetry measures present inconsistent validity and reliability results that could be biased by the quality of the studies and the difference in protocols used for gait analysis [22].…”

Background: Ankle fractures can cause significant functional impairment in the short and long term. In recent years, gait analysis using inertial sensors has gained special relevance as a reliable measurement system.Objectives: In patients with bimalleolar ankle fracture, to identify the differences between the operated and healthy ankle in the spatial-temporal gait parameters and plantar pressures; likewise, to study their relationship with clinical parameters and functional scales. Finally, to assess the reliability of a single inertial sensor, placed on the lumbar spine, in our study population.Design: Cross-sectional study.Methods: Twenty-two subjects with bimalleolar ankle fractures were included in the study. An analysis of the spatial-temporal gait parameters and plantar pressures was carried out using an inertial system (G-WALK) and a pressure platform (P-WALK). Sociodemographic and clinical information was previously collected. Differences between the operated and healthy ankle were studied for each variable and their correlation with clinical measures and functional scales; then, a multiple linear regression analysis was performed with the variables that showed a significant correlation. Finally, the intra-session test-retest reliability of the G Walk was calculated using the intraclass correlation coefficient (ICC2,1) and the standard error of measurement (SEM).Results: Statistically significant differences were found for all spatial-temporal gait parameters and dynamic plantar pressures, except for double support (-1%; p=.267). Differences were also found for clinical measures, except for ADD strength (0.6%; p=.491). Effect sizes for gait variables ranged from 0.25 to 1.02 and for clinical variables ranged from 0.15 to 2.30. The highest degree of correlation of clinical measures and functional scales was obtained with speed, cadence, stride time, and propulsion. Intra-session test-retest reliability was high to excellent (0.84<ICC>0.98). Speed, stride length, and propulsion obtained the lowest SEM scores.Conclusions: In our study population, the analysis of spatial-temporal gait parameters and dynamic plantar pressures show an evident asymmetry between both limbs; likewise, they correlate moderately with ankle range of motion, hip abductor strength, and the AOFAS scale. The G-WALK inertial sensor can be considered a reliable gait measurement system in this population.

“…Our study did not reveal differences in other lumbopelvic parameters in LDH people and healthy controls. This might be due to the young age (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) and/or the subacute chronic stage of the disease. Although we did not find differences in other analyzed parameters, the LDH needs further research on gait and lumbopelvic biomechanics.…”

“…While patient-reported outcome measures (PROMs) such as the Oswestry Disability Index (ODI) or the Roland-Morris Disability Index (RMDI) correlate well with self-reported symptoms, these are mostly not standardized for age or sex [16]; that is why one of the main physical examination components is observation of the lumbopelvic movement and body posture. Considering the lumbopelvic region function, timed up and go (TUG) and distance walk tests are commonly applied and were proposed in this study [17][18][19][20]. These tests mirror global function in a specific way with significantly less dependence on gender bias, body mass index (BMI), and age than PROMs [21].…”

Low back pain (LBP) is the most frequent cause of adult disability. One of the main reasons can be a herniated disc (lumbar disc herniation—LDH), potentially disturbing spinal movement patterns. Its influence on gait and lumbopelvic biomechanics still remains unclear. Little to no evidence was found on lumbopelvic kinematics and gait in young LDH adults. The purpose of this study was to analyze the lumbopelvic biomechanics in young adult individuals with lumbar disc herniation diagnosed by MRI. Forty-three participants (18–35 years) were divided into two groups: an LDH group (n = 19) and a control group (n = 24). All participants underwent dynamic lumbopelvic and gait measures by a G-Walk wearable device in a 6-m walking test (6MWT). The Oswestry Disability Index (ODI) questionnaire was used for subjective disability assessment. The LDH group showed higher speed (p = 0.02), lower symmetry of pelvis tilt (p = 0.01), and lower pelvis rotation (p = 0.04) compared to the healthy controls. Correlation calculations showed significance between pelvis obliquity and pelvis rotation (r = 0.53) but only in healthy controls. The lumbopelvic biomechanics shows differences in pelvis tilt and symmetry index of rotation parameters between LDH and healthy controls. In conclusion, LDH affects the gait kinematics, causing three-dimensional disorders and lack of synergy. This is probably due to pain avoidance behaviors and the compensation mechanisms of the adjacent body region.
