A Soft Robotic Device for Targeted Massage Therapy of Residual Limbs

open access: yesAdvanced Robotics Research, EarlyView.
Residual limb edema after amputation can hinder recovery and delay prosthetic fitting. This study presents a soft‐robotic wearable device that delivers sequential compression through pneumatic McKibben actuators. By replicating the principles of manual lymphatic drainage, the device generates controlled mechanotherapeutic pressure patterns, providing a

Digital Subtraction Phonocardiography (DSP) applied to the detection and characterization of heart murmurs

open access: yesBioMedical Engineering OnLine, 2011
Background During the cardiac cycle, the heart normally produces repeatable physiological sounds. However, under pathologic conditions, such as with heart valve stenosis or a ventricular septal defect, blood flow turbulence leads to the production of ...
