Resumen
Una rodillera instrumentada de bajo costo muestra una buena validez para el seguimiento del movimiento de la rodilla durante las actividades diarias. Aunque prometedor para el monitoreo, necesita un mayor desarrollo antes de su uso clínico en la rehabilitación de pacientes.
Área de la Ciencia:
- Biomecánica; Ingeniería de Rehabilitación; Tecnología Vestible
Sus antecedentes:
- El monitoreo del movimiento de la articulación de la rodilla durante las actividades de la vida diaria (AVDI) es crucial para la rehabilitación del paciente y la evaluación funcional.; Los métodos actuales pueden ser costosos o poco prácticos para el monitoreo continuo en el mundo real.
Objetivo del estudio:
- Evaluar la validez de una rodillera instrumentada de bajo costo para cuantificar la función de la rodilla durante las AVDI.; Comparar el rendimiento de la rodillera con un sistema de análisis de movimiento estándar de oro.
Principales métodos:
- Se desarrolló una plataforma de sensores para recopilar datos del plano sagital de la rodilla de 13 participantes sanos.; Los participantes realizaron cinco tareas de AVDI: caminar, caminar en pendiente, subir escaleras, sentarse y manipular objetos.; Se compararon los datos de la rodillera instrumentada con un sistema de análisis de movimiento estándar de oro.
Principales resultados:
- La rodillera demostró una validez de buena a excelente (RMSE: 4,97-8,65°) para el seguimiento de los ángulos y las velocidades angulares de la articulación de la rodilla.; Se observaron diferencias en las fases temprana y tardía del movimiento, con resultados instantáneos muy similares al estándar de oro (sesgo medio: 4,97-8,65°·s-1).
Conclusiones:
- La rodillera instrumentada de bajo costo muestra potencial como una herramienta eficaz para monitorear los movimientos cotidianos de la rodilla.; Sin embargo, el sistema actual aún no es adecuado para el análisis a nivel clínico y requiere un mayor refinamiento para su aplicación clínica generalizada.

Knee Joint
3.2K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Fruit Development, Structure, and Function
25.2K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Dynamic Equilibrium
62.4K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...
