Estimation of Gross Motor Functions in Children with Cerebral Palsy Using Zebris FDM-T Treadmill

Abstract

A standardized observational instrument designed to measure change in gross motor function over time in children with cerebral palsy is the Gross Motor Function Measure (GMFM). The process of evaluating a value for the GMFM index can be time consuming. It typically takes 45 to 60 min for the patient to complete all tasks, sometimes in two or more sessions. The diagnostic procedure requires trained and specialized therapists. The paper presents the estimation of the GMFM measure for patients with cerebral palsy based on the results of the Zebris FDM-T treadmill. For this purpose, the regression analysis was used. Estimations based on the Generalized Linear Regression were assessed using different error metrics. The results obtained showed that the GMFM score can be estimated with acceptable accuracy. Because the Zebris FDM-T is a widely used device in gait rehabilitation, our method has the potential to be widely adopted for objective diagnostics of children with cerebral palsy.

Changes in Gait Patterns after Physical Therapy in Patients with Non-specific Chronic Low Back Pain: a Pilot Study

“…The zebris FDM-T system (zebris Medical GmbH, Isny im Allgä, Germany) is integrated with existing treadmill machines to capture and analyze natural gait motions under various conditions to evaluate static and dynamic gait patterns [31]. Evaluated variables were static and dynamic pressures of forefoot and backfoot (Figure 1), and spatiotemporal variables (step width, step length, stride length, phase time, cadence, and velocity).…”

Relationship between Body Posture Assessed by Dynamic Baropodometry and Dental Occlusion in Patients with and without Dental Pathology

“…In the context of gait, biomechanics analyzes parameters such as velocity, acceleration, ground reaction forces, momentum, and joint power. The Zebris pressure platform (Zebris Medical GmbH, Weitnau, Germany) [ 1 , 2 , 3 ] allows the assessment of dynamic biomechanics during gait by recording the distribution of plantar pressures using sensors.…”

“…The analysis of these variables in gait is essential to understanding the forces involved, postural control, and gait patterns of individuals. The Zebris platform represents an invaluable tool in clinical biomechanical research [1], allowing the detection of subtle alterations in movement dynamics that could be related to various pathologies, such as scoliosis [2], cerebral palsy [3], or Parkinson's disease [4]. Body posture, which involves the position of the body in relation to gravity, can be altered due to various factors, such as Sensors 2024, 24, 1921 2 of 12 hyperlordosis, hyperkyphosis, or deviations of the pelvis [5,6].…”
