INTRODUÇÃO: O acidente vascular encefálico (AVE) é um quadro neurológico agudo de repercussões amplas, que exige de suas vítimas programas de reabilitação desafiadores na promoção da função. Nesse contexto, a Realidade Virtual (RV) é uma ferramenta de interface na reabilitação que pode gerar altos índices de motivação do paciente e permitir adaptação da terapia ao seu nível de função. OBJETIVO: Verificar o efeito da RV por meio de videogame sobre o controle postural de um indivíduo pós-AVE. MATERIAIS E MÉTODOS: Um indivíduo pós-AVE com um ano de lesão foi submetido a um protocolo de reabilitação física com videogame numa frequência de três vezes por semana por um período de 12 semanas. Anteriormente e após o programa foi realizada dinamometria por plataforma de força para análise de variáveis relacionadas ao centro de pressão (COP). RESULTADOS: Na reavaliação, observou-se que a amplitude de deslocamento médio-lateral (x) aumentou 67% na condição de olhos abertos (OA) e fechados (OF); amplitude anteroposterior (y) aumentou 25 e 44% em OA e OF, respectivamente; área aumentou 109 e 141% em OA e OF; velocidade diminuiu 26 e 0,27% em OA e OF. CONCLUSÃO: A RV como interface na reabilitação possivelmente ampliou a exploração da base de suporte para manutenção da estabilidade, constituindo recurso adicional no tratamento desses indivíduos.

Objective: To verify the effects of gait and robotic stair training with G-EO System, associated with conventional rehabilitation, on gait speed and endurance and trunk control of stroke participants. Methods: Retrospective study with 28 participants in the chronic phase of the disease. G-EO System was used for gait and stair robotic intervention. 20-session protocol of 20 minutes associated with conventional multidisciplinary therapy. The 10-meter Walk Test (10mWT), 6-minute Walk Test (6MWT) and Trunk Impairment Scale (TIS) tools were used. P values <0.05 were considered statistically significant with Wilcoxon test before and after intervention. Results: Significant differences found in the tests. TIS presented initial mean value of 14.29 (± 5.30) and final value of 17.04 (± 4.49), with p = 0.00044. 10mWT presented average initial velocity of 0.498 m/s (± 0.27) and final velocity of 0.597 m/s (± 0.32), p = 0.00008. 6mWT presented mean initial value of 155.89m (± 85.96) and final value of 195.39m (± 109.78), p = 0.00152. Conclusion: Gait and stair robotic therapy, associated with conventional therapy, was effective in promoting increased speed, endurance aptitude for greater gait distances and trunk control in individuals with chronic stroke after stroke.

Strokes cause the main neurological impairments in adults around the world. They can result in neuromotor and cognitive deficits. Among the neuromotor deficits there is spasticity; this affects the planning of movements and posture control. The postural control system is essential for functional independence in daily life activities and is, therefore, one of the main goals to achieve in rehabilitation programs. These programs have various therapeutic elements aimed at providing stimulus to the individual, which help them control their movements and stance more efficiently. Among these techniques is neuromuscular electrical stimulation, which contributes to decreasing spasticity and other benefits. When used for functional tasks it is called Functional Electrical Stimulation (FES). Objective: The purpose of this study was to verify the response of the postural control in two individuals with hemiparesis by stroke after the application of the FES over a short period time. Method: The experimental protocol had four phases. A: pre-FES; B: Immediately after the application of FES; C: 45 minutes after the application of FES; D: 90 minutes after application of FES. In each phase, the participants were positioned on a force platform and made three attempts to do the chosen task: touching the fingertip-to-floor test. Results: The software Matlab 7.0 provided the variable center-of-pressure velocities along the mediolateral (Vmx) and anteroposterior (Vmy) axes. In this way it was possible to see that, even when the participants showed a reduction in Vmx and Vmy, it was by less than 1%. Conclusion: This may indicate postural regulatory activity similar to before the application of FES, and even less postural regulatory activity when the centerof-pressure velocities were greater at the start, even 90 minutes after the application of FES.
