ABSTRACT
Objective:To explore the effect of respiratory muscle endurance training on the blood pressure, lung function, respiratory muscle strength and motor capacity of persons with hypertension.Methods:Sixty persons with essential hypertension were randomly divided into an experimental group and a control group, each of 30. The experimental group received 8 weeks of inspiratory resistance training with an intensity of 55% of their maximum inspiratory air pressure (MIP) while the control group had an intensity of 10% MIP with the other training conditions the same as those of the experimental group. Both groups practiced 30 times as a set, two sets a day, 4 days a week. Blood pressure, lung function and respiratory muscle strength were measured before and after the intervention, and motor capacity was measured using the 6-minute walk test (6MWT).Results:After the intervention, the average MIP of the experimental group had increased significantly (to 123.6±13.9 from 83.5±9.8cmH 2O). The average 6MWT time of the experimental group had also improved significantly, but there were no significant differences in any of the control group observations. Conclusion:Eight weeks of respiratory muscle endurance training can improve the inspiratory muscle strength and motor capacity of patients with essential hypertension, but it has no effect on blood pressure or lung functioning.
ABSTRACT
Introducción La órtesis activa es uno de los principales temas de investigación en el campo de la rehabilitación y recuperación motora de una extremidad lesionada. Dentro de las lesiones podemos resaltar la lesión en el plexo braquial el cual genera la pérdida total de la capacidad motora del miembro superior. Materiales y métodos Esta investigación identifica el nivel de discapacidad de esta lesión y busca mejorar la capacidad motora de las personas con lesiones en el plexo braquial mediante el uso de una órtesis. Resultados Se obtuvo una órtesis activa construida con material ABS, impresa por una impresora 3D, con la finalidad de reducir costos y el uso de un sensor muscular EMG MyoWare activado con el musculo del hombro para controlar dos servomotores ubicados en el codo y muñeca. Discusión Se logró mejorar la capacidad motora de dos pacientes que padecen esta lesión logrando realizar flexión de codo, extensión de muñeca y flexión de muñeca con la ayuda de la órtesis construida, así como también se identificaron algunas dificultades que se deben considerar para tener un producto totalmente funcional.
Background Active orthosis is one of the main research topics in rehabilitation field and recovery of an injured limb. Within the injuries we can highlight the injury of brachial plexus generates the total loss of motor capacity of the upper limb. Materials and methods This research identifies the level of disability of this lesion and seeks to improve the motor capacity of people with lesions in the plexus by using an active orthosis. Results We built a printed by a 3D printer with ABS material, and using a MyoWare EMG muscle sensor activated with shoulder muscles to control two servomotors located at elbow and wrist joints. Discussion This work was able to improve the motor skills of two patients suffering from this injury, achieving elbow flexion, wrist extension and wrist flexion with the help of the built-in orthosis, as well as identifying some difficulties that must be considered in order to have a fully functional product.

PURPOSE: To investigate the relationship between gross motor capacity and neuromuscular function in children with cerebral palsy (CP) through a short-term intensive intervention. METHODS: Twenty-four children younger than 6 years of age (17 boys, 7 girls, mean age±standard deviation, 42.71±14.43 months) who were diagnosed with CP underwent short-term intensive treatment for 8 weeks. An evaluation of gross motor function capacity using the gross motor function measure (GMFM-66 and GMFM-88) was performed to measure muscle strength, selective motor control (SMC), and spasticity, factors related to neuromusculoskeletal function. Changes in spasticity, strength, range of motion, selective motor function, and exercise intensity scores were evaluated in terms of the gross motor function classification system (GMFCS) and ages. RESULTS: The GMFM-88 and GMFM-66 scores significantly increased, by 4.32±4.04 and 2.41±1.51%, respectively, following the 8-week intervention. The change in the GMFM-66 score did not reflect a statistically significant difference in the GMFCS level. However, there was a statistically significant difference in the GMFM-88 score change in individuals at GMFCS Level III, the strength and spasticity of subjects at GMFCS Levels I–II did not significantly differ (p < 0.05). The changes in the GMFM-66 scores for strength, SMC, range of motion (ROM), and spasticity significantly differed according to age (p < 0.05) in children aged 36 months and older. Overall, there was a statistically significant difference in strength, SMC, and spasticity (p < 0.05) before and after intensive short-term treatment. CONCLUSION: The 8-week short-term intensive care intervention improved the motor function score of study participants, emphasizing the need for early intervention and additional research in this area.

Eighteen male college students who exercised regularly (the trained group) and 20 students who did not participate in regular exercise activities (the control group) were evaluated.<BR>Cold-induced vasodilation (CIVD) and maximal oxygen intake (VO<SUB>2</SUB>max) for each student were measured in May for four consecutive years. In addition, the motor capacity test devised by the Ministry of Education was given to each student. CIVD and values of motor capacity obtained from the students are summarized as follows;<BR>A. The motor capacity test consists of five items (motor skills) . There was no significant difference in muscle strength between the trained group and the control group. The degrees of improvement in explosive power and endurance capacity over the three years were greater in the trained group. It was significant that the degree of improvement in the total scores for the motor capacity test over the three years was 21% in the trained group in contrast to only 8% in the control group. While VO<SUB>2</SUB>max increased markedly in the trained group, it remained almost unchanged in the control group. The degress of improvement in VO<SUB>2</SUB>max over the three years were 25% in the trained group and 8% in the control group. The values in the control group were almost the same as the physical fitness standards, but those of the trained group were higher than the standards.<BR>B. Mean skin temperature and temperature at first rise in the trained group were higher throughout the three years than those in the control group. The time of temperature rise became shortened over three years in the trained group, but in contrast became rather longer in the control group. The range of variations in the amplitude of temperature was 9°C-13°C in the trained group and around 10°C in the control group. Resistance index (RI) of the trained group was higher in the first year; by the time the students became seniors, there was a 43% increase in RI. In contrast, RI in the control group was almost unchanged. The degree of improvement over the three years was 10% in the latter group.<BR>C. The correlation coefficient of RI with scores from the motor capacity test was 0.499 in the trained group and 0.270 in the control group. The correlation coefficient for all the subjects was 0.605. The correlation coefficient of RI with VO<SUB>2</SUB>max was 0.500 in the trained group, 0.160 in the control group and 0.623 in all the subjects. These values indicate that CIVD values and improvement in motor capacity are closely related, and that the interdependence of these two parameters is particularly strong in trained individuals.<BR>These results indicate that the degree of CIVD is determined not only by genetic factors and chronic exposure to cold temperatures but also by physical training.
