RESUMO
BACKGROUND: Brain-computer interfaces can enable communication for people with paralysis by transforming cortical activity associated with attempted speech into text on a computer screen. Communication with brain-computer interfaces has been restricted by extensive training requirements and limited accuracy. METHODS: A 45-year-old man with amyotrophic lateral sclerosis (ALS) with tetraparesis and severe dysarthria underwent surgical implantation of four microelectrode arrays into his left ventral precentral gyrus 5 years after the onset of the illness; these arrays recorded neural activity from 256 intracortical electrodes. We report the results of decoding his cortical neural activity as he attempted to speak in both prompted and unstructured conversational contexts. Decoded words were displayed on a screen and then vocalized with the use of text-to-speech software designed to sound like his pre-ALS voice. RESULTS: On the first day of use (25 days after surgery), the neuroprosthesis achieved 99.6% accuracy with a 50-word vocabulary. Calibration of the neuroprosthesis required 30 minutes of cortical recordings while the participant attempted to speak, followed by subsequent processing. On the second day, after 1.4 additional hours of system training, the neuroprosthesis achieved 90.2% accuracy using a 125,000-word vocabulary. With further training data, the neuroprosthesis sustained 97.5% accuracy over a period of 8.4 months after surgical implantation, and the participant used it to communicate in self-paced conversations at a rate of approximately 32 words per minute for more than 248 cumulative hours. CONCLUSIONS: In a person with ALS and severe dysarthria, an intracortical speech neuroprosthesis reached a level of performance suitable to restore conversational communication after brief training.

STUDY DESIGN: Non-randomized clinical trial. OBJECTIVES: Examine the feasibility, physical and psychosocial effects of a high intensity functional training (HIFT) exercise program for people with spinal cord injury (pSCI) and their care partners (CPs). SETTING: Community fitness center in a Medically Underserved Area (Fort Smith, USA.) METHODS: A single-group design with three assessment points (before the program, at midpoint (13 weeks), and post-program (25 weeks) was used to examine the effects of up to 49 HIFT sessions over 25-weeks. Sessions were 60 to 75 min in duration and adapted to the abilities of participants. Feasibility measures included recruitment, retention, attendance, safety and fidelity (exercise intensity rated via session-Rating of Perceived Exertion (RPE). Physical measures included cardiovascular endurance, anaerobic power, and muscular strength. Psychosocial measures included perceived social support for exercise, exercise self-efficacy and health-related quality of life. RESULTS: Fourteen pSCI (7 with paraplegia and 7 with tetraplegia, 2 females) and 6 CPs (4 females) were included (median age = 60) (IQR = 15.8). Recruitment rates were 40% for pSCI and 32% for CPs. On average, participants attended 73% (22%) of exercise sessions with a median session-RPE of 5 (IQR = 1). Retention rates were 83% and 67% for pSCI and CPs, respectively. For pSCI and their CPs, large effect sizes were observed for cardiovascular endurance, anaerobic power, muscular strength, and social support for exercise. CONCLUSIONS: For pSCI and their CPs, HIFT appears feasible and potentially leads to improvements in physical and psychosocial health for both groups.

The prognosis for locked-in syndrome after acquired brainstem injury is unfavourable. However, partial recovery of motor function occurs in many patients and benefits from intensive rehabilitation. Here we evaluate two patient cases and results of a questionnaire among medical doctors specialised in rehabilitation. We define bottlenecks in the treatment of acute locked-in syndrome in the ICU. Locked-in patients have a years-long life expectancy once they have survived the acute phase. There is no validated prognostic instrument to predict recovery, but even small neurological recovery can have large functional benefits. Recovery may take place over an extended period of time, up to years after onset. To unlock the potential to recover we recommend to start with early rehabilitation while the patient is still in the ICU on life sustaining treatment This may set the patient off along the road from locked-in to unlocked.

Following tetraplegia, independence for completing essential daily tasks, such as opening doors and eating, significantly declines. Assistive robotic manipulators (ARMs) could restore independence, but typically input devices for these manipulators require functional use of the hands. We created and validated a hands-free multimodal input system for controlling an ARM in virtual reality using combinations of a gyroscope, eye-tracking, and heterologous surface electromyography (sEMG). These input modalities are mapped to ARM functions based on the user's preferences and to maximize the utility of their residual volitional capabilities following tetraplegia. The two participants in this study with tetraplegia preferred to use the control mapping with sEMG button functions and disliked winking commands. Non-disabled participants were more varied in their preferences and performance, further suggesting that customizability is an advantageous component of the control system. Replacing buttons from a traditional handheld controller with sEMG did not substantively reduce performance. The system provided adequate control to all participants to complete functional tasks in virtual reality such as opening door handles, turning stove dials, eating, and drinking, all of which enable independence and improved quality of life for these individuals.

A fisioterapia utiliza vários recursos e métodos para intervenções no tratamento da Encefalopatia Crônica Não Progressiva da Infância (ECNPI) ou paralisia cerebral (PC), entre eles a Kinesio Taping® (KT) e a Terapia Neuromotora Intensiva (TNMI). Esses métodos podem ser considerados relativamente novos, o que leva à necessidade do desenvolvimento de pesquisas para verificar seus efeitos em crianças com PC. O presente estudo objetivou verificar os efeitos da KT® e da TNMI na postura sentada de crianças com PC do tipo quadriparesia/quadriplegia espástica. Para isso, foram avaliadas 6 crianças, com uma média de idade de 6,25±2,69 anos. As avaliações aconteceram por meio do software SAPO, no qual os dados são obtidos em centímetros e a análise consiste na avaliação da vertical (eixo Y), comparando os lados esquerdo e direito, sendo assim possível a análise das assimetrias de maneira precisa. Com relação aos resultados, não foi identificada diferença significativa (p > 0,05) da aplicação de KT® na comparação entre efeitos imediato, agudo e crônico para os momentos pré e pós aplicação imediata da KT®. No entanto, de forma descritiva, o uso de KT® associado à TNMI favoreceu o alinhamento na postura sentada, principalmente para acrômios e Espinha ilíaca ânterossuperior (EIAS). Nota-se, portanto, que as evidências do uso de KT®, como coadjuvante durante a TNMI, ainda são inconclusivas em crianças com PC do tipo quadriparesia/plegia.
Physical therapy uses various resources and methods for intervention in the Chronic Non-Progressive Childhood Encephalopathy (CNPCE) or cerebral palsy (CP) interventions, including Kinesio Taping® (KT) and Intensive Neuromotor Therapy (INMT). These methods are relatively new, which leads to the need for the development of research to verify effects in children with CP. The present study analyzed the effects of KT® and INMT on the sitting posture of children with spastic quadriplegia. In order to do this, six (6) children (mean age 6.25±2.69 years) were evaluated. The evaluations took place through SAPO software, where data are obtained in centimeters and the analysis consists of the evaluation of the vertical (Y) axis, comparing the left and right side, thus being possible to precisely analyze any asymmetries. Regarding the results, no significant difference (p > 0.05) was observed with the application of KT® in the comparison between immediate, acute and chronic effect for the moments before and immediately after KT® application. However, descriptively, the use of KT® associated with INMT favored alignment in sitting posture, mainly for acromial and anterior superior iliac spine (ASIS). The results show that evidence of the use of KT® as an adjuvant during INMT is still inconclusive in children with CP quadriparesis/plegia.

ABSTRACT Introduction: In tetraplegic persons, the lack of function of the upper limb constitutes the utmost barrier to their autonomy, which is why many of them consider the reconstruction and recovery of their upper limbs to be very important. Objective: To describe the restoration of the caliper and the grip of quadriplegic hand with the use of Zancolli and House techniques. Method: A longitudinal, prospective study was carried out in 12 tetraplegic patients who came to the upper limp consultation at Frank País International Orthopedic Scientific Complex, from January 2013 to December 2016. The study variables were age, sex, injury etiology, classification (according to Giens international classification), dependence on daily activities (Barthel index), function of the limb (Mowery functional classification), personal satisfaction (Allien and Machle scale) and complications. Zancolli and House techniques were used. The information was collected from the medical records of the admitted patients. Data was processed in a microcomputer database with Word and Excel systems. The SPSS 17 statistical system was also used. Results: Eleven men and one woman (24 hands in total) were treated from the total of patients in the sample. The average age was 30 years, with 8.6 years of latency period. Traumatic spinal cord injury was collected as the etiology of the spinal cord injury. According to the international Giens classification, there were ten patients in group 4, and two patients in group 5. Complications occurred in three cases. With surgery, all patients were able to change from dependent to independent status. Regarding hand function, the vast majority of the sample was classified as excellent, and regarding personal satisfaction, nine patients reported feeling excellent. Conclusions: Zancolli and House techniques favor the restoration of the caliper and the grip of the quadriplegic hand, improve joint mobility, muscle strength and the functionality of the hand. These procedures favor the autonomy of the patient and have a high degree of satisfaction(AU)

OBJECTIVE: To evaluate the movement strategies of quadriplegics, assisted by neuromuscular electrical stimulation, on reach and palmar grasp using objects of different weights. METHODS: It was a prospective clinical trial. Four chronic quadriplegics (C5-C6), with injuries of traumatic origin, were recruited and all of them had their reach and palmar grasp movement captured by four infrared cameras and six retro-reflective markers attached to the trunk and right arm, assisted or not by neuromuscular electrical stimulation to the triceps, extensor carpi radialis longus, extensor digitorum communis, flexor digitorum superficialis, opponens pollicis and lumbricals. It was measured by a Neurological and Functional Classification of Spinal Cord Injuries of the American Spinal Injury Association, Functional Independence Measure and kinematic variables. RESULTS: The patients were able to reach and execute palmar grasp in all cylinders using the stimulation sequences assisted by neuromuscular electrical stimulation. The quadriplegics produced lower peak velocity, a shorter time of movement and reduction in movement segmentation, when assisted by neuromuscular electrical stimulation. CONCLUSION: This study showed that reach and palmar grasp movement assisted by neuromuscular electrical stimulation was able to produce motor patterns more similar to healthy subjects. Level of evidence IV; Case series.

MÉTODOS: Estudo clínico prospectivo. Quatro quadriplégicos crônicos (C5-C6) com lesões de origem traumática foram recrutados e todos tiveram o alcance e movimento de preensão palmar capturado por quatro câmeras infravermelho e seis marcadores retrorreflexivos fixados no tronco e braço direito, assistidos ou não por estimulação neuromuscular do tríceps, extensor radial longo do carpo, extensor dos dedos, flexor superficial dos dedos, oponente do polegar e músculos lumbricais. A medida foi feita com base na Classificação Neurológica e Funcional de Lesões Medulares da American Spinal Injury Association, na Medida de Independência Funcional e em variáveis cinemáticas. RESULTADOS: Os pacientes foram capazes de alcançar e realizar preensão palmar em todos os cilindros utilizando as sequências de estimulação auxiliadas por estimulação elétrica neuromuscular. Os quadriplégicos produziram menor velocidade de pico, menor tempo de movimento e redução na segmentação do movimento, quando foram auxiliados pela estimulação elétrica neuromuscular. CONCLUSÃO: Este estudo mostrou que o alcance e o movimento de preensão palmar assistidos por estimulação elétrica neuromuscular foi capaz de produzir padrões motores mais semelhantes aos dos indivíduos saudáveis. Nível de evidência IV; Série de casos.

OBJETIVO: Determinar se o treinamento de músculos inspiratórios pode aumentar a força e endurance desses músculos em pacientes com quadriplegia. MÉTODOS: Oito pacientes quadriplégicos (7 homens e 1 mulher) com lesão medular cervical entre C4 e C7 foram submetidos ao treinamento de músculos inspiratórios utilizando-se um resistor de carga linear ajustado em 30 por cento da PImáx. As sessões de treinamento foram realizadas com os pacientes sentados 5 vezes por semana por 8 semanas. Tempo de endurance, PImáx, PEmáx e CVF foram medidos antes do treinamento e nas semanas 4 e 8. RESULTADOS: Em comparação ao valor basal médio, houve um aumento da PImáx, mensurada na posição sentada, nas semanas 4 e 8 (-83,0 ± 18,9 cmH2O vs. -104,0 ± 19,4 e -111,3 ± 22,7 cmH2O). Houve aumento da PEmáx, também na posição sentada, na semana 4 (de 36,8 ± 8,1 a 42,6 ± 8,8 cmH2O). Houve uma melhora na FVC na 4ª semana (de 2,1 ± 0,8 a 2,5 ± 0,6 L, representando um incremento de 24 ± 22 por cento). O tempo de endurance (sentado) não apresentou um aumento significativo entre o momento basal e a semana 8 (29,8 ± 21,0 min vs. 35,9 ± 15,5 min; aumento de 173 ± 233 por cento). CONCLUSÕES: Pacientes com quadriplegia podem se beneficiar com o treinamento com baixas cargas (30 por cento da PImáx), com melhora da força dos músculos inspiratórios, CVF e efetividade dos músculos expiratórios.
OBJECTIVE: To determine whether inspiratory muscle training can increase strength and endurance of these muscles in quadriplegic patients. METHODS: Eight quadriplegic patients (7 males and 1 female) with injury to the lower cervical spine (segments C4-C7) were submitted to inspiratory muscle training with a threshold inspiratory muscle trainer adjusted to 30 percent of MIP. The training sessions were carried out with the patients in a sitting position, 5 days a week for 8 weeks. Endurance time, MIP, MEP and FVC were determined at baseline, week 4 and week 8. RESULTS: In comparison with the mean baseline value, there was an increase in MIP, measured in the sitting position, at weeks 4 and 8 (-83.0 ± 18.9 cmH2O vs. -104.0 ± 19.4 cmH2O and -111.3 ± 22.7 cmH2O). There was an increase in MEP, also in the sitting position, at week 4 (from 36.8 ± 8.1 to 42.6 ± 8.8 cmH2O). There was an improvement in FVC at week 4 (from 2.1 ± 0.8 to 2.5 ± 0.6 L, representing an increase of 24 ± 22 percent). Although there was an increase in endurance (sitting) at week 8, the difference was not significant in comparison with the baseline value (29.8 ± 21.0 vs. 35.9 ± 15.5 min, an increase of 173 ± 233 percent). CONCLUSIONS: Quadriplegic patients can benefit from training at low loads (30 percent of MIP), which can improve inspiratory muscle strength, FVC and expiratory muscle performance.

During sessions of physical therapy, a tetraplegic patient with incomplete spinal cord section at C5 level was found to have changes in the posture post intervention. The therapy consisted of tactile stimulation in specific points of his body to generate reflex patterns of muscle activation (Vojta therapy principies). To quantify these postural changes in the subject, the center of pressure displacement in sitting posture was measured. An analysis of the changes observed in postural control through fourteen months of follow-up is presented and discussed in the report bellow.
Durante las sesiones de terapia física, en un paciente tetrapléjico con sección incompleta de la médula espinal a nivel C5, se encontró que hubo cambios en la postura, posterior a la intervención. La terapia consistió en estimulación táctil en puntos específicos del cuerpo para generar patrones reflejos de activación muscular (principios de la terapia Vojta). Para cuantificar estos cambios de postura en el sujeto, se midió el desplazamiento del centro de gravedad en la posición sentada. Un análisis de las variaciones observadas en el control postural, a través de catorce meses de seguimiento, se presentan y discuten en el siguiente informe.

Introduction: Functional impairment in patients with high spinal cord injuries is associated to ventilatory dysfunction due to paretic respiratory muscles, which causes alterations in the ventilatory and in the cough mechanisms. Respiratory muscle training has been studied as a therapeutic alternative for this group of patients with no conclusive results, whereas a mixed protocol, which stimulates both inspiratory and expiratory muscles, had not been previously investigated. Objective: To evaluate the effects of systematic respiratory muscle training during four months, on pulmonary function, respiratory muscles strength and effort tolerance, cough efficacy and dyspnea perception, in a group of quadriplegic patients with at least one year of evolution post injury. Method: A quasi-experimental design was used. Six adults with cervical spinal cord injuries were enlisted and incorporated in a mixed respiratory muscles training for four months. Pulmonary function, respiratory muscles strength and resistance, cough efficacy and dyspnea perception were assessed pre and post training. Results: The application of the mixed training protocol significantly improved inspiratory muscle strength (p = 0,028),respiratory muscles effort tolerance (p = 0,028) and cough efficacy (p = 0,034).The other measures did not reach statistical significance. Conclusion: Mixed(inspiratory/expiratory) muscular training, shows partially favorable results in the improvement of pulmonary function. Studies using greater numbers of patients are necessary to achieve more categorical results.
Introducción: El compromiso funcional en pacientes con lesiones medulares altas se asocia a disfunción ventilatoria por paresia de musculatura respiratoria y provoca alteraciones ventilatorias y en el mecanismo de la tos. El entrenamiento de la musculatura respiratoria ha sido analizado como alternativa terapéutica para neumo este grupo de pacientes sin resultados concluyentes, mientras que un protocolo mixto, que estimule músculos inspiratorios y espiratorios no ha sido estudiado con anterioridad. Objetivo: Evaluar la respuesta del sistema respiratorio al entrenamiento sistemático de la musculatura respiratoria durante cuatro meses, sobre la función pulmonar, fuerza y tolerancia al esfuerzo de la musculatura respiratoria, eficacia de la tos y percepción de disnea de un grupo de pacientes tetrapléjicos. Materiales y Métodos: Se aplicó un diseño cuasi-experimental. Seis pacientes con lesiones medulares cervicales de al menos un año de evolución fueron reclutados e incluidos en un programa de entrenamiento mixto de la musculatura respiratoria durante 4 meses. Se evaluó la función pulmonar, fuerza y resistencia de la musculatura respiratoria, eficacia de la tos y percepción de disnea antes y después del período de entrenamiento. Resultados: El protocolo de entrenamiento mixto aplicado incrementó significativamente la fuerza muscular inspiratoria (p= 0,028), la tolerancia al esfuerzo de los músculos respiratorios (p = 0,028) y la eficacia de la tos (p = 0,034). El incremento en todas las otras variables medidas no alcanzó significancia estadística. Conclusión: El entrenamiento muscular mixto(inspiratorio/espiratorio) muestra resultados parcialmente favorables en la mejoría de indicadores de función pulmonar.

Respiratory complications are the first cause of death in patients with tetraplegia, including both the acute and chronic stage of the disease. They include a wide variety of respiratory problems, such as repeated pneumonias, atelectasis, unsatisfactory secretions manage, respiratory failure, hypoventilation, and other complex pathologies such as pulmonary embolism and sleep apnea syndrome. It has been postulated that the main cause of all these respiratory complications is weakness of inter costais and abdominal muscles, and partial or complete dysfunction of the diaphragm. Today we have multiple therapeutic alternatives to prevent, manage and specifically treat the multiple types of complications. The main objective of this article is to review the different therapeutical alternatives and encourage the study of this important topic.
Las complicaciones respiratorias son la principal causa de muerte en los pacientes con tetraplejia, tanto en el período agudo como crónico. En esta categoría se incluyen diversas alteraciones como neumonías recurrentes, atelectasias, mal manejo de las secreciones, insuficiencia respiratoria e hipoventilación. Además, son frecuentes patologías más complejas como el tromboembolismo pulmonar y la apnea obstructiva del sueño. Se postula que las causas principales de los problemas respiratorios son la debilidad de los músculos intercostales y abdominales, y la disfunción parcial o total del diafragma. Hoy en día existen múltiples alternativas terapéuticas para prevenir, manejar y tratar en forma específica las diversas complicaciones. El propósito de este artículo es revisar las opciones terapéuticas actualmente vigentes y despertar el interés entre los clínicos para profundizar más en este importante tema.

La lesión medular (LM) es un problema que afecta sobre todo a la población en edad laboral y, por lo tanto, sus repercusiones rebasan el ámbito familiar. La LM es irreversible para la mitad de las víctimas y en la actualidad los tratamientos existentes consisten en la asistencia y la estabilización espinal. Con el reconocimiento de la existencia de células madre (CM), el tratamiento de la LM ha recibido otro enfoque. Las CM se encargan de la renovación de los tejidos durante la vida del individuo y su reparación en caso de lesión. Las CM más atractivas desde el punto de vista terapéutico son las capaces de generar diversos tejidos, obtenibles con facilidad, y cuya manipulación es aceptable en términos éticos. En este artículo se presentan algunos de los estudios realizados con CM de diversos orígenes y su aplicación al tratamiento de la LM.
Spinal cord injury (SCI) is a trauma problem striking mainly working age adults, therefore affecting society beyond the victims family circle. Most of the victims of SCI will never recover; therapy for this type of injury consists basically on spinal cord support and stabilization. With the discovery of stem cells (SC), SCI treatment has been given another chance. Stem cells are responsible for tissue renewal throughout the individuals life, as well as tissue repair when needed. From the therapeutic point of view, the most appealing SC are those capable of generating a variety of tissues, those easily harvested, and finally, those ethically unquestioned. This article summarizes some studies carried with SC of various origins and their application to SCI treatment.

Quadriplegic subjects present extensive muscle mass paralysis which is responsible for the dramatic decrease in bone mass, increasing the risk of bone fractures. There has been much effort to find an efficient treatment to prevent or reverse this significant bone loss. We used 21 male subjects, mean age 31.95 ± 8.01 years, with chronic quadriplegia, between C4 and C8, to evaluate the effect of treadmill gait training using neuromuscular electrical stimulation, with 30-50 percent weight relief, on bone mass, comparing individual dual-energy X-ray absorptiometry responses and biochemical markers of bone metabolism. Subjects were divided into gait (N = 11) and control (N = 10) groups. The gait group underwent gait training for 6 months, twice a week, for 20 min, while the control group did not perform gait. Bone mineral density (BMD) of lumbar spine, femoral neck, trochanteric area, and total femur, and biochemical markers (osteocalcin, bone alkaline phosphatase, pyridinoline, and deoxypyridinoline) were measured at the beginning of the study and 6 months later. In the gait group, 81.8 percent of the subjects presented a significant increase in bone formation and 66.7 percent also presented a significant decrease of bone resorption markers, whereas 30 percent of the controls did not present any change in markers and 20 percent presented an increase in bone formation. Marker results did not always agree with BMD data. Indeed, many individuals with increased bone formation presented a decrease in BMD. Most individuals in the gait group presented an increase in bone formation markers and a decrease in bone resorption markers, suggesting that gait training, even with 30-50 percent body weight support, was efficient in improving the bone mass of chronic quadriplegics.

Blood pressure pattern was analyzed in 12 complete quadriplegics with chronic lesions after three months of treadmill gait training. Before training, blood pressure values were obtained at rest, during treadmill walking and during the recovery phase. Gait training was performed for 20 min twice a week for three months. Treadmill gait was achieved using neuromuscular electrical stimulation, assisted by partial body weight relief (30-50 percent). After training, blood pressure was evaluated at rest, during gait and during recovery phase. Before and after training, mean systolic blood pressures and heart rates increased significantly during gait compared to rest (94.16 ± 5.15 to 105 ± 5.22 mmHg and 74.27 ± 10.09 to 106.23 ± 17.31 bpm, respectively), and blood pressure decreased significantly in the recovery phase (86.66 ± 9.84 and 57.5 ± 8.66 mmHg, respectively). After three months of training, systolic blood pressure became higher at rest (94.16 ± 5.15 mmHg before training and 100 ± 8.52 mmHg after training; P < 0.05) and during gait exercise (105 ± 5.22 mmHg before and 110 ± 7.38 mmHg after training; P < 0.05) when compared to the initial values, with no changes in heart rate. No changes occurred in blood pressure during the recovery phase, with the lower values being maintained. A drop in systolic pressure from 105 ± 5.22 to 86.66 ± 9.84 mmHg before training and from 110 ± 7.38 to 90 ± 7.38 mmHg after training was noticed immediately after exercise, thus resulting in hypotensive symptoms when chronic quadriplegics reach the sitting position from the upright position.

Introduction: It is important to evaluate the effectiveness of the therapeutic endeavour, in order to improve rehabilitation programs in the motor area in patients with neuromusculoskeletal disabilities. Objective: To evaluate changes in the functional independence between admission and discharge from specific treatments in patients with cerebral palsy and spinal cord lesion, and explore whether gender, age or diagnosis, can predict the progress of children in these types of treatments. Patients and Methods: A single cohort study, consisting of 624 subjects of three years or more with cerebral palsy and 155 with spinal cord injury, attending to specific rehabilitation programs in Teletón Chile Institute from 2007-2008. In the analysis, was used the difference between the admission and discharge WeeFIM score and decision trees with p < 0.05. Results: In 264/624 of the cerebral palsy children (42.3 percent)increase discharge score; 321/624 (51.4 percent) remain the same and 39/624 (6.3 percent) decrease; in spinal cord injury 93/155 patients (60 percent) improve, 58/155 (37.4 percent) do not change and 4/155 (2.6 percent) decrease; the improvement occurs mainly in self-care activities; the decision trees show that specific treatments have best result for diplegia and hemiplegia in children under 6 years; in spinal cord injury, for thoracic bifid spine with hydrocephalus and acquired tetraplegia. Conclusion: Specific treatments have a better outcome for children with cerebral palsy hemiplegia and spine lesions, it is associated with the initial diagnosis; the age acquires predictive characteristics for children with hemiplegia and diplegias under 6 years; WeeFIM is poorly sensitive to detect changes in extreme scores and in short duration rehabilitation programs.
Introducción: Es importante evaluar la efectividad del quehacer terapéutico, con el fin de mejorar los programas de rehabilitación en el área motora de los pacientes con discapacidades neuromusculoesqueléticas. Objetivo: Evaluar cambios en la independencia funcional entre ingreso y alta de tratamientos específicos en pacientes con parálisis cerebral y lesión medular, y explorar si el género, edad y diagnóstico, permiten pronosticar el progreso de los niños en este tipo de tratamientos. Pacientes y Método: Estudio de cohorte única, constituida por 624 sujetos de 3 años o más con parálisis cerebral y 155 con lesión medular, asistentes a programas específicos de rehabilitación de Instituto Teletón Chile en 2007-2008. En el análisis, se usó diferencia de puntaje de WeeFIM entre ingreso y alta, y árboles de decisión con p < 0,05. Resultados: En parálisis cerebral 264/624 (42,3 por ciento) de los niños, aumenta puntaje de alta; 321/624 (51,4 por ciento) permanece igual y 39/624 (6,3 por ciento) desmejora; en lesión medular 93/155 pacientes (60 por ciento) mejora, 58/155 (37,4 por ciento) no cambia y 4/155 (2,6 por ciento) desmejora; la mejoría se produce principalmente en actividades de autocuidado; los árboles de decisión indican que los tratamientos específicos tendrían mejor resultado para diplejías y hemiplejias en menores de 6 años; en lesión medular, para espina bífida torácica con hidrocefalia y tetraplejia. Conclusiones: Los tratamientos específicos tienen mejor resultado para niños con hemiplejia por parálisis cerebral y alteraciones raquimedulares altas; el aumento del puntaje, está asociado al diagnóstico inicial; la edad adquiere carácter predictivo para niños con hemiplejias y diplejías menores de 6 años; WeeFIM es poco sensible para detectar cambios en puntajes extremos y en programas de rehabilitación de corta duración.

Este trabalho discute o uso da estimulação elétrica na reabilitação sensoriomotora de membros superiores paralisados. A restauração da função motora de preensão foi obtida pela aplicação da estimulação elétrica neuromuscular, em seqüência de ativação adequadas a realização de atividades do cotidiano como comer, beber, escrever e digitar. Uma luva instrumentalizada com sensores de força possibilitou quantificar o padrão de movimento exercido artificialmente. Esse sistema foi utilizado como alçã de realimentação para a restauração de uma propriocepção através da aplicação da estimulação eletrotáctil, possibilitando a evocação de sensações tácteis codificadas, relacionadas ao movimento artificial. A integração sensoriomotora se deu pela aplicação simultânea dos sistemas desenvolvidos, possibilitando desde a restauração de padrões funcionais de preensão, até o reconhecimento do padrão de movimento exercido através das sensações evocadas artificialmente.

Se estudiaron 21 lesionados raquimedulares, con 5 a 14 años de evolución, de una edad promedio de 33 años, la mayoría varones parapléjicos, cuya etiología más frecuente fue traumática con predominio de lesión dorsal y lumbar, mediante entrevistas semiestructuradas, exámenes clínicos y estudio de ficha médica. Comprobamos que después de su lesión, la mayoría sigue estudiando, trabajan en forma estable, se casan, y la integración al medio social y familiar es buena. Hay escasa dependencia en la deambulación en los parapléjicos, pero no así en los tetrapléjicos. La mayoría tiene una vida sexual activa con dificultades en la erección y eyaculación. Las caricias son fundamentales, así como la satisfacción de la pareja. No se encontró diferencia de patología psiquiátrica en relación a la población general, ni predominio de algún tipo de personalidad
