Efficient decellularization of equine tendon with preserved biomechanical properties and cytocompatibility for human tendon surgery indications

Dominique Pioletti, Nathalie Hirt-Burri, Jens Antons, Cédric Peneveyre, Anthony Grognuz, Pierre-Arnaud Aeberhard

Chronic and acute tendon injuries are frequent afflictions, for which treatment is often long and unsatisfactory. When facing extended injuries, matrices and scaffolds with sufficient biomechanical properties are required for surgical repair and could addi ...

Biomechanical effects of passive hip springs during walking

Passive spring-like structures can store and return energy during cyclic movements and thereby reduce the energetic cost of locomotion. That makes them important components of the human body and wearable assistive devices alike. This study investigates how ...

Simplifying Exosuits: Kinematic Couplings in the Upper Extremity during Daily Living Tasks

In the past few years, several light-weight soft wearable robots, so called exosuits, for upper extremity assistance have been developed. The design of exosuits is often based on a bio-mimetic design approach, mimicking the human biomechanics. However, in ...

Modular and minimally constraining lower limb exoskeleton for enhanced mobility and balance augmentation

Mohamed Bouri, Amalric Louis Ortlieb

In one embodiment, the exoskeleton structure is fastened to the body of the user by a brace and at the foot level. The exoskeleton includes at least one set of three joints corresponding to the hip abduction/adduction, the hip flexion/extension and the kne ...

A Closed-Loop EMG-Assisted Shoulder Model

Ehsan Sarshari

The human shoulder is a complex musculoskeletal system. Knowledge about its kinematics and dynamics can help improve associated treatments. However, to date direct measurements of these quantities can be only granted through invasive investigations or expe ...

Joint Inertial Sensor Orientation Drift Reduction for Highly Dynamic Movements

Kamiar Aminian, Benedikt Fasel, Julien Chardonnens

Inertial sensor drift is usually corrected on a single-sensor unit level. When multiple sensor units are used, mutual information from different units can be exploited for drift correction. This study introduces a method for a drift-reduced estimation of t ...

Evaluating upper limb impairments in multiple sclerosis by exposure to different mechanical environments

Martina Coscia

Multiple sclerosis is a chronic, autoimmune and neurodegenerative disease affecting multiple functional systems and resulting in motor impairments associated with muscle weakness and lack of movement coordination. We quantified upper limb motor deficits wi ...

Neural and muscular factors both contribute to plantar-flexor muscle weakness in older fallers

Jean-Baptiste Mignardot

Plantar-flexor muscles are key muscles in the control of postural sway. Older fallers present lower maximal plantar-flexor performance than older non-fallers; however, the mechanisms underlying this motor impairment remain to be elucidated. This study aime ...

Design of a measuring device for Mallet Finger treatment

Khawla Belqadhi

A mallet finger is an injury that affects the extensor tendon at the Distal interphalangeal joint (DIP). It results from a hyperflexion of the said tendon which can result in a stretching or tearing of the tendon or an avulsion of the tendon’s insertion on ...

A simulation framework for humeral head translations

Dominique Pioletti, Alexandre Terrier, Alain Farron, Philippe Müllhaupt, Ehsan Sarshari

Humeral head translations (HHT) play a crucial role in the glenohumeral (GH) joint function. The available shoulder musculoskeletal models developed based on inverse dynamics however fall short of predicting the HHT. This study aims at developing a simulat ...
