Description

DISPOSITIVO DE REHABILITACIÓN PARA ARTICULACIÓN DE MUÑECA REHABILITATION DEVICE FOR WRIST JOINT
CAMPO TÉCNICO DE LA INVENCIÓN TECHNICAL FIELD OF THE INVENTION
La presente invención se relaciona con el campo técnico de la mecánica, electrónica, interfaz inalámbrica, y más específicamente con dispositivos médicos y de rehabilitación fisioterapéutica, ya que aporta un dispositivo de rehabilitación para articulación de muñeca. The present invention is related to the technical field of mechanics, electronics, wireless interface, and more specifically with medical and physiotherapeutic rehabilitation devices, since it provides a rehabilitation device for the wrist joint.
ANTECEDENTES DE LA INVENCION BACKGROUND OF THE INVENTION
Las patologías de muñeca provocan consecuencias importantes para los pacientes, como dolor, falta de fuerza, dificultades de movilidad, etc. El daño a cualquiera de las partes de la muñeca puede causar dolor y afectar la capacidad de usar la muñeca y la mano. Wrist pathologies cause important consequences for patients, such as pain, lack of strength, mobility difficulties, etc. Damage to any part of the wrist can cause pain and affect the ability to use the wrist and hand.
A menudo, las lesiones en la muñeca se producen al caer hacia adelante sobre la mano extendida. Esto puede causar esguinces, distensiones e incluso fracturas. La fractura del escafoides es una fractura que se produce en un hueso de la muñeca del lado del pulgar. Es posible que este tipo de fractura no aparezca en las radiografías inmediatamente después de la lesión. Wrist injuries are often caused by falling forward onto an outstretched hand. This can cause sprains, strains, and even fractures. A scaphoid fracture is a fracture that occurs in a wrist bone on the thumb side. This type of fracture may not show up on x-rays right after the injury.
Cualquier actividad que implica movimiento repetitivo de la muñeca, desde golpear una pelota de tenis o tocar el violonchelo hasta conducir a campo traviesa, puede inflamar los tejidos que se encuentran alrededor de las articulaciones o provocar fracturas por sobrecarga, especialmente cuando realizas el movimiento durante horas, sin tomar un descanso. La enfermedad conocida como "De Quervain" es una lesión por tensión repetitiva que provoca dolor en la base del dedo pulgar. Any activity that involves repetitive movement of the wrist, from hitting a tennis ball or playing the cello to driving cross country, can inflame the tissues around the joints or lead to stress fractures, especially when you do the movement for hours , without taking a break. De Quervain's disease is a repetitive strain injury that causes pain at the base of the thumb.
La artrosis es un tipo de artritis que se produce cuando el cartílago que amortigua los extremos de los huesos se deteriora con el paso del tiempo. La artrosis en la muñeca es poco frecuente y, generalmente, se produce solo en personas que se han lesionado la muñeca en el pasado. Osteoarthritis is a type of arthritis that occurs when the cartilage that cushions the ends of bones breaks down over time. Wrist osteoarthritis is rare and usually occurs only in people who have injured their wrist in the past.
La artritis reumatoide es un trastorno en el que el sistema inmunitario del organismo ataca sus propios tejidos. La artritis reumatoide comúnmente involucra a la muñeca. Si una muñeca se ve afectada, la otra suele estarlo también. Rheumatoid arthritis is a disorder in which the body's immune system attacks its own tissues. Rheumatoid arthritis commonly involves the wrist. If one wrist is affected, the other usually is as well.
El síndrome del túnel carpiano se manifiesta cuando se produce un aumento de presión en el nervio mediano a medida que este atraviesa el túnel carpiano, un pasaje en el lado de la palma de la muñeca. Carpal tunnel syndrome occurs when there is increased pressure on the median nerve as it passes through the carpal tunnel, a passageway on the palm side of the wrist.
Los quistes de los ganglios se producen en la parte de la muñeca contraria a la palma; pueden ser dolorosos, y el dolor puede empeorar o mejorar con la actividad. Ganglion cysts occur on the side of the wrist away from the palm; they can be painful, and the pain can get worse or better with activity.
La enfermedad de Kienbóck es un trastorno que generalmente afecta a los adultos jóvenes e implica el colapso progresivo de uno de los huesos pequeños de la muñeca. La enfermedad de Kienbóck se produce cuando se interrumpe el suministro de sangre a este hueso. Kienbock's disease is a disorder that usually affects young adults and involves the progressive collapse of one of the small bones in the wrist. Kienbock disease occurs when the blood supply to this bone is interrupted.
Entre las rupturas más comunes se encuentran, la fractura de radio o la fractura de escafoides, cuadros de dolor cubital (lesiones del fibrocartílago triangular, impactación cúbito-carpiana, etc.), procesos degenerativos (artrosis de muñeca, lesiones en tendones y ligamentos), tendinitis, lesiones del ligamento escafo- lunar y afecciones nerviosas como el síndrome del túnel del carpo o túnel carpiano. Among the most common ruptures are radius fractures or scaphoid fractures, ulnar pain conditions (triangular fibrocartilage injuries, ulnar-carpal impaction, etc.), processes degenerative (wrist osteoarthritis, tendon and ligament injuries), tendinitis, scapholunate ligament injuries and nerve disorders such as carpal tunnel syndrome or carpal tunnel.
Para el tratamiento de dichas patologías se pueden utilizar técnicas quirúrgicas como la artroscopia o la cirugía percutánea, la inmovilización con férulas, así como técnicas fisioterapéuticas posteriores a una intervención quirúrgica, e incluso en ocasiones no es necesaria la intervención, y con una terapia física en el área afectada es posible recobrar la movilidad gradualmente de manera parcial o total de la extremidad, posterior a una importante cantidad de sesiones de rehabilitación. For the treatment of these pathologies, surgical techniques such as arthroscopy or percutaneous surgery, immobilization with splints, as well as physiotherapeutic techniques after surgery can be used, and sometimes the intervention is not necessary, and with physical therapy in the affected area, it is possible to gradually recover partial or total mobility of the extremity, after a significant number of rehabilitation sessions.
Se ha desarrollado una gran variedad de mecanismos rehabilitadores para la articulación de la muñeca, los cuales ayudan de manera importante a reducir el número de sesiones de rehabilitación, ya que debido a que son mecanismos asistidos, se centran en movimientos específicos para obtener mayor movilidad en menor tiempo. A wide variety of rehabilitative mechanisms have been developed for the wrist joint, which significantly help to reduce the number of rehabilitation sessions, since, due to the fact that they are assisted mechanisms, they focus on specific movements to obtain greater mobility in the wrist. shorter time.
