Hand loss is a highly disabling event that markedly affects the quality of life. [] Key Result This feedback enabled the participant to effectively modulate the grasping force of the prosthesis with no visual or auditory feedback. Three different force levels were distinguished and consistently used by the subject.

Stanisa Raspopovic Prostheses Restoring Natural Sensory Feedback in Real-Time Bidirectional Hand

The authors connected electrodes in the arm nerves to sensors in two fingers of the Raspopovic and colleagues incorporated a feedback system connected to the amputee's arm nerves, which delivers discernible only by eye or from experience.

Restoring tactile sensations via neural interfaces for real-time force-and-slippage closed-loop control of bionic hands

It is shown that force and slipperage sensations can be elicited in an amputee by means of biologically inspired slippage detection and encoding algorithms, supported by a stick-slip model of the performed grasp.

A closed-loop hand prosthesis with simultaneous intraneural tactile and position feedback

This study shows that sensory substitution based on intraneural stimulation can deliver position feedback in real time and in conjunction with somatotopic tactile feedback, and paves a way to more sophisticated bidirectional bionic limbs conveying richer, multimodal sensations.

Biomimetic encoding model for restoring touch in bionic hands through a nerve interface

An approach to convey tactile feedback through electrical stimulation of the residual somatosensory nerves that mimics the aggregate activity of tactile fibers that would be produced in the nerve of a native hand during object interactions is described.

A soft neuroprosthetic hand providing simultaneous myoelectric control and tactile feedback.

The design, fabrication and performance of a soft, low-cost and lightweight neuroprosthetic hand that provides simultaneous myoelectric control and tactile feedback is reported and it is shown that one individual with a transradial amputation wearing the soft neuro Prosthesis can regain primitive touch sensation and real-time closed-loop control.

Neural feedback strategies to improve grasping coordination in neuromusculoskeletal prostheses

The findings confirm, in line with the neuroscientific literature, that somatosensory feedback is necessary for motor coordination during grasping and indicates that feedback is more relevant under uncertainty, and its effectiveness can be influenced by the selected neuromodulation paradigm and arguably also the prior experience of the prosthesis user.

Intraneural sensory feedback restores grip force control and motor coordination while using a prosthetic hand

The results show that intraneural sensory feedback increases the subject’s ability in regulating the GF and allows for improved performance over time, which opens up new possibilities to improve the quality of life of amputees using a neural prosthesis.

An osseointegrated human-machine gateway for long-term sensory feedback and motor control of artificial limbs

A percutaneous osseointegrated (bone-anchored) interface that allows for permanent and unlimited bidirectional communication with the human body and demonstrates in one subject that implanted electrodes provide a more precise and reliable control than surface electrodes, regardless of limb position and environmental conditions, and with less effort.

The development of a sensory feedback system based on the phenomenon of evoked tactile sensation at the stump skin of residual limb induced by transcutaneous electrical nerve stimulation (TENS) and the feasibility to restore the perceptual sensation from prosthetic fingers to amputee is demonstrated.

Humans Can Integrate Augmented Reality Feedback in Their Sensorimotor Control of a Robotic Hand

It is demonstrated that it is possible to deliver effective information through AR feedback in a compact and wearable fashion and this feedback modality may be exploited for delivering sensory feedback to amputees in a clinical scenario.



Design of a cybernetic hand for perception and action

The modular and flexible design of the CyberHand makes it suitable for incremental development of sensorization, interfacing, and control strategies and, as such, it will be a useful tool not only for clinical research but also for addressing neuroscientific hypotheses regarding sensorimotor control.

Control of multifunctional prosthetic hands by processing the electromyographic signal.

The traditional methods used to control artificial hands by means of EMG signal are presented, in both the clinical and research contexts, and what could be the future developments in the control strategy of these devices are introduced.

Prosthetic hands from Touch Bionics

The innovative design of prosthetic hands now in production from a Scottish spin‐off company allows patients to achieve many functional and natural‐looking hand configurations from simple “open” and “close” signals.

Targeted muscle reinnervation for real-time myoelectric control of multifunction artificial arms.

The results suggest that reinnervated muscles can produce sufficient EMG information for real-time control of advanced artificial arms, as well as improving the function of prosthetic arms.

A robust, real-time control scheme for multifunction myoelectric control

It is shown that, by exploiting the processing power inherent in current computing systems, substantial gains in classifier accuracy and response time are possible and other important characteristics for prosthetic control systems are met.

Persistent hand motor commands in the amputees' brain.

Stump muscle EMG activity is measured in an amputee experiencing a frozen phantom limb, and in three below-elbow amputees with vivid phantom movements after inducing an ischaemic block to suggest that preserved hand movement representations can instruct the remaining muscles to move in such a way as if the limb is still there.

Responsiveness of the somatosensory system after nerve injury and amputation in the human hand

It is concluded that the somatosensory system remains able to process information from a nerve fascicle that has lost its cutaneous territory, and somatoensory localization remains accurate despite the presumed central reorganization that takes place after nerve division or amputation.

Redirection of cutaneous sensation from the hand to the chest skin of human amputees with targeted reinnervation

The perception of an amputated limb arising from stimulation of reinnervated chest skin may allow useful sensory feedback from prosthetic devices and provides insight into the mechanisms of neural plasticity and peripheral regeneration in humans.
