Knee Implant Loosening Detection: A Vibration Analysis Investigation

Kamiar Aminian, Hossein Rouhani, Arash Arami

Knee implant loosening is mainly caused by the weakness of the prosthesis-bone interface and is the main reason for surgical revisions. However, pre-operative diagnosis is difficult due to lack of accurate tests. In this study, we developed a vibration-bas ...

Biomimetic Intraneural Sensory Feedback Enhances Sensation Naturalness, Tactile Sensitivity, and Manual Dexterity in a Bidirectional Prosthesis

Giulio Rognini, Edoardo D'Anna, Silvestro Micera, Francesco Maria Petrini, Ivo Strauss, Giacomo Valle, Francesco Iberite

Peripheral intraneural stimulation can provide tactile information to amputees. However, efforts are still necessary to identify encoding strategy eliciting percepts that are felt as both natural and effective for prosthesis control. Here we compared the n ...

Upper limb cortical maps in amputees with targeted muscle and sensory reinnervation

Roberto Martuzzi, Olaf Blanke, Michel Akselrod, Wietske Van der Zwaag, Giulio Rognini, Roy Salomon, Maria Laura Blefari, Andrea Serino, Elisa Canzoneri

Neuroprosthetics research in amputee patients aims at developing new prostheses that move and feel like real limbs. Targeted muscle and sensory reinnervation (TMSR) is such an approach and consists of rerouting motor and sensory nerves from the residual li ...

Fascicular nerve stimulation and recording using a novel double-aisle regenerative electrode

Silvestro Micera

Objective. As artificial prostheses become more refined, they are most often used as a therapeutic option for hand amputation. By contrast to extra- or intraneural interfaces, regenerative nerve electrodes are designed to enable electrical interfaces with ...

A somatotopic bidirectional hand prosthesis with transcutaneous electrical nerve stimulation based sensory feedback

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Fiorenzo Artoni

According to amputees, sensory feedback is amongst the most important features lacking from commercial prostheses. Although restoration of touch by means of implantable neural interfaces has been achieved, these approaches require surgical interventions, a ...

Decoding bipedal locomotion from the rat sensorimotor cortex

Silvestro Micera, Grégoire Courtine, Lucia Florinda Friedli Wittler, Rubia van den Brand, Jacopo Rigosa

Objective. Decoding forelimb movements from the firing activity of cortical neurons has been interfaced with robotic and prosthetic systems to replace lost upper limb functions in humans. Despite the potential of this approach to improve locomotion and fac ...

Design and integration of an instrumented knee prosthesis

Matteo Simoncini

Total knee arthroplasty is nowadays one of the most important orthopedic surgery. It consists of a procedure in which parts of the knee are replaced by a prosthesis. The largest indication for total knee arthroplasty is osteoarthritis, a knee disease that ...

Estimation of prosthetic knee angles via data fusion of implantable and wearable sensors

Kamiar Aminian, Roderik Berthelin, Arnaud Barré, Arash Arami

In this work, we studied a combination of embedded magnetic measurement system in a knee prosthesis and wearable inertial sensors to estimate two knee joint rotations namely flexion-extension and internal-external rotations. The near optimal sensor configu ...
