Resumen
Una nueva herramienta, RECORD, mide con precisión la rotación del hombro durante la caminata para evaluar las distorsiones del esquema corporal en la investigación psicológica y la práctica clínica. El sistema de código abierto ofrece una solución rentable para la evaluación estandarizada de la percepción corporal.
Área de la Ciencia:
- Psicología Psicología Psicología.
- La biomecánica es la biomecánica.
- Tecnología médica Tecnología médica.
Sus antecedentes:
- La comunidad psicológica carece de un método estandarizado para evaluar las distorsiones del esquema corporal en la investigación y en entornos clínicos.
- La evaluación precisa de la percepción corporal es crucial para comprender y tratar diversas afecciones psicológicas.
Objetivo del estudio:
- Para introducir RECORD (RECOnfiguRing la Evaluación del Cuerpo en Movimiento), una herramienta clínica novedosa y rentable para evaluar la rotación del hombro.
- Proporcionar un marco estandarizado para medir las distorsiones del esquema corporal, centrándose específicamente en el movimiento del hombro durante la ambulación.
Principales métodos:
- RECORD emplea una sola unidad de medición de inercia inalámbrica (IMU) colocada en el acromion para medir la rotación del hombro.
- Un algoritmo basado en cuaterniones asegura la robustez en el procesamiento de datos.
- El rendimiento del sistema se valida con un sistema de captura de movimiento estándar, que incluye pruebas de referencia y métricas de precisión.
Principales resultados:
- El sistema RECORD logra una precisión constante de 1.39° dentro del rango de tareas probadas.
- La precisión se mantiene estable independientemente de la distancia o el movimiento del sujeto durante la evaluación.
Conclusiones:
- El dispositivo RECORD es adecuado para evaluar la rotación del hombro tanto en psicología clínica como en entornos de investigación.
- La disponibilidad de código abierto del hardware, algoritmos y software de RECORD en GitHub promueve la accesibilidad y los avances impulsados por la comunidad.

36.4K
In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

01:30Impact of Schemas
222
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

1.7K
Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:

1.6K
Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
