Background. the basal ganglia's circuit dysfunction has a major role in a range of movement disorders. Some evidence has shown that exercise can improve performance, especially locomotor activity after brain injuries. There was currently insufficient information to define the impacts of intensity, duration, and frequency of different exercises. Objectives. in this study, we examine the role of mild forced treadmill exercise and GABA-B agonist on locomotor activity and anxiety-behavior dysfunction of ibotenic acid injection in striatum. Methods. forty male Wistar rats were randomly split into five groups. The animals received ibotenic acid infusions into striatum bilaterally. Locomotor activities of rats were assessed by open-field apparatus. Results. Our results showed that mild forced treadmill exercise and GABA-B could significantly increase distance in open field and decrease anxietybehavior in treadmill and drug groups than lesion group (P=0.008 and P=0.001 respectively). Conclusion. There is no significant difference between treadmill and drug groups. So, mild forced treadmill exercise and baclofen could improve motor dysfunction of lesion by ibotenic acid injection in striatum and anxiety-behavior.

En el presente artículo se expone el entrenamiento de una Red Neuronal Convolucional (RNC) para discriminación de herramientas de uso común en tareas de mecánica, electricidad, carpintería y similares. Para el caso, se toman como objetivos de entrenamiento pinzas, destornilladores, tijeras y alicates, los cuales puedan ser identificados por la red, y permite dotarle a un brazo robótico la facultad de identificar una herramienta deseada - de entre las anteriores - para su posible entrega a un usuario. La arquitectura neuro convolucional empleada para la red presenta un porcentaje de acierto del 96% en la identificación de las herramientas entrenadas.

— Over the rapid developments in mechatronics field, number of robotic platforms are emerged in medical field particularly in GAIT rehabilitation treatment targeted to recover the cardio vascular patients with acute neurological defects. Robotics Assisted Treadmill Exercise (RATE) is well known and efficient GAIT technique for the patient recovery. This work aims to develop a novel based adaptive controlled RATE, targeted to provide optimal exercise intensity for patients by feedback from oxygen uptake rate along with the heart rate with focus on impulse and ramp tracking. The proposed controller has communicate with feedback system for control of mechanical work rate which takes its target work rate from the automatic oxygen uptake control loop. This work also compares the efficiency and clinical feasibility of Adaptive Controlled – RATE with the Feedback controlled – RATE. Results of adaptive control of oxygen uptake profiles and disturbance rejection tests by impulse tracking demonstrated the technical feasibility and accuracy of the approach. The approach presented here provides adaptive control of exercise intensity during RATE by biofeedback and voluntary adaptation of the hip and knee forces by the individual.
