Prototyping and Experimental Analysis of Active Offloading Footwear for Patients With Diabetes Using an Array of Magnetorheological Fluid–Based Modules

Yves Perriard, Yoan René Cyrille Civet, Paolo Germano, Christian Köchli, Bhawnath Tiwari

Diabetic foot ulceration is a serious challenge worldwide which imposes an immense risk of lower extremity amputation and in many cases may lead to the death. The presented work focuses on the offloading requirements using an active approach and considers ...

Intelligent plantar pressure offloading for the prevention of diabetic foot ulcers and amputations

Yves Perriard, Yoan René Cyrille Civet, Christian Köchli, Sofia Lydia Ntella, Kenny Jeanmonod, Bhawnath Tiwari

The high prevalence of lower extremity ulceration and amputation in people with diabetes is strongly linked to difficulties in achieving and maintaining a reduction of high plantar pressures (PPs) which remains an important risk factor. The effectiveness o ...

Bidirectional bionic limbs: a perspective bridging technology and physiology

Silvestro Micera

Precise control of bionic limbs relies on robust decoding of motor commands from nerves or muscles signals and sensory feedback from artificial limbs to the nervous system by interfacing the afferent nerve pathways. Implantable devices for bidirectional co ...

Biomechanical Measures for Fall Risk Assessment and Fall Detection in People with Transfemoral Amputations for the Next-Generation Prostheses: A Scoping Review

Silvestro Micera

Introduction: Transfemoral amputations are known to compromise balance control capabilities, thus increasing the probability of falling. Current research in robotic prostheses is exploring novel strategies to assess the risk of fall and, if required, enabl ...

The various forms of sensorimotor plasticity following limb amputation and their link with rehabilitation strategies

Estelle Emeline Raffin

Limb amputation is characterized by complex and intermingled brain reorganization processes combining sensorimotor deprivation induced by the loss of the limb per se, and compensatory behaviors, such as the over-use of the intact or remaining limb. While a ...

Material surface detection on various body parts: a preliminary study for temperature substitution for upper arm amputees

Silvestro Micera, Solaiman Shokur

Experiments have shown that healthy subjects can detect materials solely relying on the material's thermal properties at their fingertip. We are interested in developing a non-invasive temperature display for sensory substitution for patients with arm ampu ...

Current Solutions and Future Trends for Robotic Prosthetic Hands

Silvestro Micera, Solaiman Shokur, Vincent Alexandre Mendez, Francesco Iberite

The desire for functional replacement of a missing hand is an ancient one. Historically, humans have replaced a missing limb with a prosthesis for cosmetic, vocational, or personal autonomy reasons. The hand is a powerful tool, and its loss causes severe p ...

Foot Control of a Surgical Laparoscopic Gripper via 5DoF Haptic Robotic Platform: Design, Dynamics and Haptic Shared Control

Aude Billard, Mohamed Bouri, Walid Amanhoud, Jacob Hernandez Sanchez

Foot devices have been ubiquitously used in surgery to control surgical equipment. Most common applications are foot switches for electro-surgery, endoscope positioning and tele-robotic consoles. Switches fall short of providing continuous control as requi ...

Cortical plasticity after hand prostheses use: Is the hypothesis of deafferented cortex "invasion" always true?

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Pablo Garcia del Valle, Giacomo Valle, Francesco Iberite

Objective: To study motor cortex plasticity after a period of training with a new prototype of bidirectional hand prosthesis in three left trans-radial amputees, correlating these changes with the modification of Phantom Limb Pain (PLP) in the same period. ...
