Open AccessFeasibility of generating 90 Hz vibrations in remote implanted magnets
Limb amputation not only reduces the motor abilities of an individual, but also destroys afferent channels that convey essential sensory information to the brain. Significant efforts have been made in the area...

Open AccessLocalization accuracy of multiple magnets in a myokinetic control interface
Magnetic localizers have been widely investigated in the biomedical field, especially for intra-body applications, because they don’t require a free line-of-sight between the implanted magnets and the magnetic...

Open AccessA database of high-density surface electromyogram signals comprising 65 isometric hand gestures
Control of contemporary, multi-joint prosthetic hands is commonly realized by using electromyographic signals from the muscles remaining after amputation at the forearm level. Although this principle is trying...

Open AccessContinuous supplementary tactile feedback can be applied (and then removed) to enhance precision manipulation
Human sensorimotor control of dexterous manipulation relies on afferent sensory signals. Explicit tactile feedback is generally not available to prosthetic hand users, who have to rely on incidental informatio...

Open AccessThe preload force affects the perception threshold of muscle vibration-induced movement illusions
The control and the execution of motor tasks are largely influenced by proprioceptive feedback, i.e. the information about the position and movement of the body. In 1972, it was discovered that a vibratory sti...

Open AccessHumans adjust their grip force when passing an object according to the observed speed of the partner’s reaching out movement
The way an object is released by the passer to a partner is fundamental for the success of the handover and for the experienced fluency and quality of the interaction. Nonetheless, although its apparent simpli...

Open AccessImproving internal model strength and performance of prosthetic hands using augmented feedback
The loss of an arm presents a substantial challenge for upper limb amputees when performing activities of daily living. Myoelectric prosthetic devices partially replace lost hand functions; however, lack of se...

Open AccessTouch and Hearing Mediate Osseoperception
Osseoperception is the sensation arising from the mechanical stimulation of a bone-anchored prosthesis. Here we show that not only touch, but also hearing is involved in this phenomenon. Using mechanical vibra...
