Autoencoder-derived Single Summary Metric to Assess Gait Quality

Introduction: The persistent high rate of disability in people after stroke in Poland and globally requires continuous analysis of the effectiveness of rehabilitation. This review of the global literature analyzes the effectiveness of two therapeutic concepts in relation to changes in the autonomic nervous system and gait quality. Material and Methods: We searched PubMed for available literature using keywords. The search included literature available in English between January 2000 and June 2017. Results: Most studies described in this literature review did not show any significant advantage in terms of effectiveness of neurorehabilitation methods over conventional ones. Conclusions: The effectiveness of rehabilitation focuses mainly on modulating brain plasticity associated with neurologic deficits in the central nervous system, ignoring the autonomic nervous system.

The Moment

The most common cause of neurological disability in childhood is cerebral palsy. The objectives of the treatment of children with cerebral palsy are the acquisition and maintenance of new motor skills; prevention of the development of contractures and other secondary orthopedic complications; decrease in the level of pain; improving the level of childcare. At the same time, the provision of treatment and rehabilitation assistance to children with cerebral palsy requires an integrated, systematic approach. The article describes the route of rehabilitation of children with cerebral palsy in the Chuvash Republic from the moment of diagnosis until reaching the age of 18. The study was carried out on the basis of an analysis of data from the regional register of children with cerebral palsy at all stages of treatment and rehabilitation (habilitation). The first stage includes the identification of risk groups for cerebral palsy, conservative, surgical specialized medical care. The register of children with cerebral palsy made it possible to keep records of patients at the stages of treatment and rehabilitation with an assessment of the results. At the second stage, high-tech conservative and surgical treatment is carried out. After operations, patients are sent for rehabilitation to a 24-hour hospital or to a Rehabilitation Center for Children (over 3 years, 1.5 thousand children were treated, 25.7% after operations). The third stage is organized at the outpatient clinic level and in specialized sanatoriums. For 20142018 the coverage of children with cerebral palsy with conservative treatment increased 1.9 times, with botulinum therapy 2.6 times, the proportion of those who received surgery decreased to 22.4%. 92.7% of patients of the Register are covered by conservative treatment. 33.3% of operated children were referred for sanatorium-resort treatment. The control section of the rehabilitation results showed an increase in the proportion of children with improved gait quality, the ability to stand independently, walk (with support), and an increase in the average level of physical activity. A multi-level system of interagency interaction in the provision of treatment and rehabilitation assistance to children with cerebral palsy in Chuvash Republic made it possible to ensure a sufficient amount of basic and availability of highly qualified medical care, effective management and control of the stages of rehabilitation.

Gait Quality

Increased oxygenated hemoglobin concentration of the prefrontal cortex (PFC) has been observed during linear walking, particularly when there is a high attention demand on the task, like in dual-task (DT) paradigms. Despite the knowledge that cognitive and motor demands depend on the complexity of the motor task, most studies have only focused on usual walking, while little is known for more challenging tasks, such as curved paths. To explore the relationship between cortical activation and gait biomechanics, 20 healthy young adults were asked to perform linear and curvilinear walking trajectories in single-task and DT conditions. PFC activation was assessed using functional near-infrared spectroscopy, while gait quality with four inertial measurement units. The Figure-of-8-Walk-Test was adopted as the curvilinear trajectory, with the “Serial 7s” test as concurrent cognitive task. Results show that walking along curvilinear trajectories in DT led to increased PFC activation and decreased motor performance. Under DT walking, the neural correlates of executive function and gait control tend to be modified in response to the cognitive resources imposed by the motor task. Being more representative of real-life situations, this approach to curved walking has the potential to reveal crucial information and to improve people’ s balance, safety, and life’s quality.

The Impact

Background: Subjects with Down Syndrome (DS) are characterized by specific physiological alterations, including musculoskeletal abnormalities. Flat Foot (FF), caused by hypotonia and ligament laxity, represents one of the most common disabling disorders in this population. Conservative treatments promote the use of orthopaedic insoles and plantar supports. The aim of this study was to evaluate the impact of Foot Orthoses (FOs) on the gait pattern of subjects with DS, assessing the biomechanical effects associated with their use. Methods: Twenty-nine subjects were screened under two conditions—walking barefoot (WB); with shoes and insoles (WSI), during three trials for each. Assessments were performed through the 3D gait analysis, using an optoelectronic system, force platforms, and video recording. Specifically, synthetic indices of gait kinematics, i.e., gait profile score (GPS) and gait variable score (GVS) were calculated and compared with Wilcoxon signed-rank test, to evaluate between-conditions. Results: Significant variations were found in GVS foot progression index, representative of foot rotation during walking, in adolescents only. Conclusions: Bilateral FOs has a positive immediate impact on gait quality in adolescents with DS, as confirmed by quantitative analysis. FOs prescription is an evidence-based early approach to slow down biomechanical abnormalities and prevent relative symptoms.

Healthy Control

The purpose of this study was to clarify whether a gait analysis using an accelerometer could estimate gait independence. Eighty-six stroke patients and 21 healthy control subjects participated in this study. Stroke patients were identified as dependent or independent based on their gait ability. The acceleration of the trunk and bilateral thigh was measured using three wireless sensors during walking. The root mean square, gait regularity, and symmetry were calculated from the acceleration to estimate gait quality. ANCOVA showed that gait regularity of the trunk and bilateral thigh were significantly lowest in the dependent group, regardless of gait velocity. A logistic regression analysis showed that the regularity and root mean square of the anteroposterior acceleration of the unaffected thigh were the key factors for estimating gait independence. This study suggests that an acceleration-based gait analysis facilities gait independence estimation, and is a useful tool during the rehabilitation of stroke patients.
