Use of wearable inertial sensors for the assessment of spatiotemporal gait variables in children: A systematic review

摘要

Aim: The present study aimed to perform a literature review on the use of wearable inertial sensors for gait analysis of children in clinical practice. Methods: Searches were performed in the MEDLINE, EMBASE, Cochrane Library, and PEDro databases for studies involving children or adolescents submitted to gait analysis with the use of wearable inertial sensors. No restrictions were imposed regarding the date of publication or language. Results: Three hundred twenty articles were retrieved, 14 of which met the eligibility criteria and were selected for the present systematic review. Two independent reviewers assessed the risk of bias and study quality using the ROBINS-I and AXIS scale. The studies included in the present review reported multiple outcomes of kinematic gait assessments calculated from the signals provided by the wearable sensors, performed in a hospital setting, outpatient clinic, and a familiar environment, with several types of pediatric conditions. Conclusion: The findings suggest that wearable sensors are effective for the evaluation of quantitative gait variables in children with different pediatric conditions, enabling an objective analysis that should prove useful in the processes of clinical diagnosis and rehabilitation. However, given the relatively small number of studies published on this topic, it is difficult to make strong recommendations regarding the most appropriate equipment, sensor placement, and outcomes for assessing gait in children.
