Emiliano Pablo Ravera, Adam Rozumalsky Publicado: Febrero, 2024 Abstract The authors regret that incorrect effect sizes from the statistical analysis were published in Table 1 of their study Ravera and Rozumalski (2024). The errors outlined below were due to the overwriting of variables in the Python script. These errors only affected the results of the […]

Melisa Frisoli, Sofía Poux, Melisa Deris, Paola Catalfamo Formento and Eloísa García Añino Advances in Bioengineering and Clinical Engineering Abstract The development of Human Gait Analysis since its origins has been primarily carried out in research laboratories. Currently there is a wide interest in implementing this kind of tools in the clinical setting, for which it

Emilio Pablo Ravera, Adam Rozumalsky Publicado: Junio, 2024 Abstract ​Selective dorsal rhizotomy (SDR) is commonly used to permanently reduce spas​ticity in children with cerebral palsy (CP). However, studies have yielded varying​ results regarding muscle strength and activity after SDR. Some studies indicate​ weakness or no changes, while a recent study using NMSK simulations demonstrates improvements in muscle

Beatriz Mantese, Christian G. Pirozzi Chiusa, Yamila Basilotta Marquez, María Pía Gotter Campo, Ricardo Nazar, Marcos Crespo, Alfredo Toledo, Emiliano Ravera Child’s Nervous System Objective: To analyze and compare the efficacy of two selective dorsal rhizotomy (SDR) techniques with intraoperative neurophysiological monitoring, using instrumented three-dimensional gait analysis. Introduction: SDR is a common, irreversible surgical treatment

Emiliano Pablo Ravera, Adam Rozumalski Gait & Posture Introduction: Most clinical gait laboratories utilize the conventional gait model or one of its variants for planning and evaluating treatment in children with cerebral palsy (CP). Estimation of the hip joint center (HJC) is identified as a major source of error that can influence the model outcomes

Emiliano Pablo Ravera, Adam Rozumalski Gait & Posture Introduction: Spasticity in children with cerebral palsy (CP) can produce an increase in muscle activity with unknown consequences in muscle energy expenditure. Selective dorsal rhizotomy (SDR) is shown to significantly reduce spasticity. However, Zaino et al. (2020) showed that changes in energy consumption following SDR are not

Emiliano Pablo Ravera and Adam Rozumalski Gait & Posture Introduction: Spasticity in children with cerebral palsy (CP) can produce an increase in muscle activity with unknown consequences in muscle energy expenditure. Selective dorsal rhizotomy (SDR) is shown to significantly reduce spasticity [Chen2019]. However, Zaino et al. (2020) showed that changes in energy consumption following SDR

Emiliano Pablo Ravera, Marcos José Crespo, Adam Rozumalski Journal of Biomechanics Abstract Children with pathological movement patterns like crouch gait present with excessive knee and hip flexion during stance phase due to multiple factors. A good treatment requires that the primary factor is reduced or eliminated to optimise the relationship between muscle energy expenditure and

Emiliano Pablo Ravera, Victoria Peterson Journal of Biomechanics Abstract The symmetrical center of rotation estimation (SCoRE) is probably one of the most used functional method for estimating the hip join center (HJC). However, it requires of complex multi-plane movements to find accurate estimations of HJC. Thus, using SCoRE for people with limited hip range of motion will

C. M. Lara-Barrios; P. Catalfamo Formento; E. Muñoz Larrosa; A. Blanco-Ortega IEEE Xplore Abstract Active lower limb assistive devices are intended to contribute to human movement activities such as locomotion.While some devices are capableto function among a variety of terrains (i.e. level surfaces, inclines, or stairs), wideinstrumentation sets (combining mechanical and bio-signal data) have been usually
