“…From our results, we may deduce that metabolic oscillations in nondisabled people have richer structures (i.e., more complex behavior) than in people with SCI. Our results support the general concept that the output of a healthy system reveals complex variability and that the complexity decreases with aging and diseases [16,[38][39]. Reduced complexity of the physiological system is widely accepted to be associated with an individual's poor abilities to adapt to environmental stimulus.…”

“…Our results support the concept that decreased nonlinear behavior of a physiological system is associated with pathological states [16,[38][39]. In nondisabled controls, a significant increase of the multifractality degree of metabolic BFO in response to local heating may be attributed to more metabolic activities and the interactions between other mechanisms.…”

Abstract-The purpose of this study was to investigate whether the multifractal detrended fluctuation analysis (MDFA) of skin blood flow oscillations (BFO) differed between nondisabled controls and people with spinal cord injury (SCI). The study of skin BFO has shown promise for assessing blood flow control mechanisms and risk for pressure ulcers. We recruited 23 subjects, including 11 people with SCI and 12 nondisabled controls. Thermally induced maximal sacral skin BFO were measured by laser Doppler flowmetry. MDFA was used to characterize nonlinear complexity of metabolic (0.0095 to 0.02 Hz), neurogenic (0.02 to 0.05 Hz), and myogenic (0.05 to 0.15 Hz) BFO. We found that maximal vasodilation was significantly smaller in people with SCI than in nondisabled controls (p < 0.05). MDFA showed that metabolic BFO exhibited less complexity in people with SCI (p < 0.05), neurogenic BFO exhibited less complexity in people with complete SCI (p < 0.05), and myogenic BFO did not show significant differences between people with SCI and nondisabled controls. This study demonstrated the feasibility of using the MDFA to characterize nonlinear complexity of BFO, which is related to vasodilatory functions in people with SCI.

Amyotrophic Lateral Sclerosis is a degenerative disorder of the central nervous system involving motor neurons, which directly affect the gait of a person. The aim of this study was to analyze the gait kinematics of patients affected by this pathology in different stages. A descriptive cross-sectional research was designed with three subjects who were classified in stages I, II and III proposed by Sinaki & Mulder. Regarding the spatialtemporal variables, it was observed that the more the stage of the pathology progresses, the further the values get from normality. In the angular kinematic parameters, there was a greater hip flexion to achieve ambulation, together with a decrease in the extension in the three joints studied. The results showed that the data from the subjects presenting amyotrophic lateral sclerosis differ from normal at all stages and the losses caused by the disease have direct influence on gait kinematics mainly with the progress of the disease when the overall symptoms become more incapacitating. Palavras-Chave:Esclerose lateral amiotrófica Marcha Cinemática RESUMO A Esclerose Lateral Amiotrófica é um distúrbio degenerativo do sistema nervoso central envolvendo neurônios motores que afetam diretamente a marcha. O objetivo deste estudo foi analisar a cinemática da marcha de indivíduos afetados por esta patologia, em diferentes estágios. Trata-se de uma pesquisa descritiva transversal em três sujeitos classificados entre os estágios I, II e III propostos por Sinaki e Mulder. Em relação às variáveis espaço-temporais, observa-se que conforme o estágio da patologia avança, mais os valores se distanciam da normalidade. Nos parâmetros cinemáticos angulares, observa-se maior flexão de quadril para conseguir deambular, somada a uma diminuição na extensão nas três articulações estudadas. Os resultados demostram que os dados destes indivíduos diferem da normalidade em todos os estágios e as perdas causadas pela doença têm influência direta na cinemática da marcha, principalmente com o progresso da doença, quando os sintomas gerais se tornam mais incapacitantes.CC BY-NC-SA 4.0 2017 RCSFMIt

“…Implementation of a targeted multidisciplinary rehabilitation program into the Huntington's disease population is anticipated to reduce dependence on the health system due to a reduction in the utilisation of health services as a result of a reduction in fall-related injuries, and may delay placement into residential and end-stage facilities by encouraging and maintaining patient independence. Huntington's disease is characterised by progressive cognitive, affective and motor deterioration over a 15-25 year period, together with a spectrum of associated physical deficits including postural instability [6][7][8][9][10] , gait impairments [11][12][13][14][15][16] and lean and fat tissue loss 17,18 .…”
