Redesign based on clinical experience of a robotic walker for hip fracture rehabilitation2023 La fractura de cadera es una lesiĆ³n frecuente en personas mayores de 65 aƱos, estando asociada a una reducciĆ³n en la esperanza de vida. Su rehabilitaciĆ³n se basa en la movilizaciĆ³n gradual mediante terapia manual. Sin embargo, estos tratamientos no suelen ser integrales, constan de ejercicios repetitivos, resultan monĆ³tonos para el paciente y su seguimiento es principalmente cualitativo. SWalker es un andador robĆ³tico basado en un sistema de tracciĆ³n y de soporte de peso, que integra sensores de marcha. Con una primera versiĆ³n de este andador se llevĆ³ a cabo un estudio clĆnico que involucrĆ³ 34 pacientes. A partir de esta experiencia se han extraĆdo los requisitos de diseƱo que se consideran claves para el desarrollo de este tipo de dispositivos. Sobre la base de estos requisitosse ha construido una segunda versiĆ³n del andador en la que se ha validado su usabilidad con 5 pacientes. Empleando la escala QUEST 2.0 se han comparado ambas versiones del andador, mostrando mejoras en la segunda versiĆ³n en seguridad, adaptabilidad y usabilidad.
- An Inexpensive and Easy to Use Cervical Range of Motion Measurement Solution Using Inertial Sensors
2018-08-07 Neck injuries and the related pain have a high prevalence and represent an important health problem. To properly diagnose and treat them, practitioners need an accurate system for measuring Cervical Range Of Motion (CROM). This article describes the development and validation of an inexpensive, small (4 cm 4 cm 8 cm), light (< 200 g) and easy to use solution for measuring CROM using wearable inertial sensors. The proposed solution has been designed with the clinical practice in mind, after consulting with practitioners. It is composed of: (a) two wearable wireless MEMS-based inertial devices, (b) a recording and report generation software application and (c) a measurement protocol for assessing CROM. The solution provides accurate (none of our results is outside the ROM ranges when compared with previously published results based on an optical tracking device) and reliable measurements (ICC = 0.93 for interrater reliability when compared with an optical tracking device and ICC > 0.90 for test-retest reliability), surpassing the popular CROM instrumentās capabilities and precision. It also fulfills the needs for clinical practice attending to effectiveness, efficiency (4 min from setup to final report) and userās satisfaction (as reported by practitioners). The solution has been certified for mass-production and use in medical environments.
