Abstract:
Despite previous studies on the restoration of tactile sensation to the fingers and the hand, there are no examples of use of the routed sensory information to finely control a prosthestic hand in complex grasp and manipulation tasks. Here, it is shown that force and slippage 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 combination of cuff and intraneural electrodes was implanted for 11 weeks in a young woman with hand amputation and was shown to provide close-to-natural force and slippage sensations, paramount for substantially improving manipulative skills with the prosthesis. Evidence is provided about the improvement of the participant’s grasping and manipulation capabilities over time resulting from neural feedback. The elicited tactile sensations enabled the successful fulfillment of fine grasp and manipulation tasks with increasing complexity. Grasp performance was quantitatively assessed by means of instrumented objects and a purposely developed metrics. Closed-loop control capabilities enabled by the neural feedback were compared with those achieved without feedback. Further, the work demonstrates that the described amelioration of motor performance in dexterous tasks had as central neurophysiological correlates changes in motor cortical plasticity and that such changes were not of purely motor origin, but were the effect of a strong and persistent drive of the sensory feedback.

Abstract:
Abstract Loss of an arm is a devastating condition that can cross all socioeconomic groups. A major step forward in rehabilitation of amputees has been the development of myoelectric prostheses. Current robotic arms allow voluntary movements by using residual muscle contraction. However, a significant issue is lack of movement control and sensory feedback. These factors play an important role in integration and embodiment of a robotic arm. Without feedback, users rely on visual cues and experience overwhelming cognitive demand that results in poorer use of a prosthesis. The complexity of the afferent system presents a great challenge of creating a closed-loop hand prosthesis. Several groups have shown progress providing sensory feedback for upper limb amputees using robotic arms. Feedback, although still limited, is achieved through direct implantation of intraneural electrodes as well as through non-invasive methods. Moreover, evidence shows that over time some amputees develop a phantom sensation of the missing limb on their stump. This phenomenon can occur spontaneously as well as after non-invasive nerve stimulation, suggesting the possibility of recreating a sensory homunculus of the hand on the stump. Furthermore, virtual reality simulation in combination with mechanical stimulation of skin could augment the sensation phenomenon, leading to better interface between human and robotic arms.

Abstract:
Neural-interfaced prostheses aim to restore sensorimotor limb functions in amputees. They rely on bidirectional neural interfaces, which represent the communication bridge between nervous system and neuroprosthetic device by controlling its movements and evoking sensory feedback. Compared to extraneural electrodes (i.e., epineural and perineural implants), intraneural electrodes, implanted within peripheral nerves, have higher selectivity and specificity of neural signal recording and nerve stimulation. However, being implanted in the nerve, their main limitation is represented by the significant inflammatory response that the body mounts around the probe, known as Foreign Body Reaction (FBR), which may hinder their rapid clinical translation. Furthermore, the mechanical mismatch between the consistency of the device and the surrounding neural tissue may contribute to exacerbate the inflammatory state. The FBR is a non-specific reaction of the host immune system to a foreign material. It is characterized by an early inflammatory phase eventually leading to the formation of a fibrotic capsule around intraneural interfaces, which increases the electrical impedance over time and reduces the chronic interface biocompatibility and functionality. Thus, the future in the reduction and control of the FBR relies on innovative biomedical strategies for the fabrication of next-generation neural interfaces, such as the development of more suitable designs of the device with smaller size, appropriate stiffness and novel conductive and biomimetic coatings for improving their long-term stability and performance. Here, we present and critically discuss the latest biomedical approaches from material chemistry and tissue engineering for controlling and mitigating the FBR in chronic neural implants.

Abstract:
La reacció de cos estrany (FBR, per les sigles en anglès) és una resposta del sistema immunitari envers qualsevol dispositiu implantat al cos. Diversos estudis han demostrat que aquesta resposta consta d’una primera fase inflamatòria seguida d’una fase de remodelació del teixit, que resulta en la encapsulació del cos estrany. Es creu que aquesta encapsulació es la causa, entre d’altres factors, de la pèrdua de funcionalitat dels elèctrodes neurals, que han de ser implantats de forma crònica per generar i registrar senyals nerviosos del sistema nerviós. En aquesta tesis s’ha fet una caracterització detallada de la FBR envers dispositius implantats als nervis perifèrics amb l’objectiu de trobar possibles dianes terapèutiques per reduir aquesta resposta i millorar la funcionalitat al llarg del temps d’elèctrodes intraneurals. Els nostres resultats mostren com la infiltració de cèl·lules immunes al nervi va presentar un màxim després de dos setmanes d’implant, sense que s’observessin diferencies entre dos dels polímers que s’utilitzen com a substrat dels elèctrodes, la poliimida i el Parilè C. En canvi, la deposició de teixit al voltant dels dispositius va evolucionar de forma diferencial entre tots dos materials. Mentre que la càpsula al voltant de la poliimida va presentar un màxim a les 2 setmanes i va estabilitzar-se, la capsula al voltant del Parilè C també va presentar un màxim a les 2 setmanes i després de mantenir-se estable durant un període de 4-8 setmanes, va continuar creixent fins al seu màxim a les 16 setmanes desprès de l’implant. L’anàlisi molecular de diferents factors inflamatoris i de remodelació de teixit no va mostrar diferencies, però, entre els dos materials. Les dos fases descrites en la FBR als nervis perifèrics van determinar possibles estratègies terapèutiques per reduir la resposta. Entre els diferents fàrmacs testats, només la dexametasona va reduir significativament la infiltració de macròfags i el gruix de la capsula al voltant dels dos polímers. A més, el tractament amb dexametasona va millorar la funcionalitat a llarg terme d’elèctrodes transversals intraneurals, en particular de les propietats d’estimulació. En conclusió, la FBR envers dispositius intraneurals presenta un patró similar a l’observat a altres teixits com l’espai subcutani i la cavitat peritoneal. A més, les diferències observades a temps crònics entre els dos materials descartarien el Parilè C com a substrat per elèctrodes intraneurals implantats crònicament. La caracterització de la FBR ha permès definir diferents estratègies terapèutiques com la dexametasona, que va millorar la funcionalitat a llarg del temps d’elèctrodes intraneurals, degut possiblement a un reducció de la infiltració cel·lular i de la càpsula de teixit depositat.<br>The foreign body reaction (FBR) is an immune-mediated response to any device implanted in the body. Several studies have shown that it is characterized by a first inflammatory phase followed by a tissue remodeling phase, which results in the encapsulation of the foreign body. This encapsulation is thought to cause, among other factors, the progressive decline in function reported in neural electrodes, which should remain chronically implanted in the body to generate and record nerve signals from the nervous tissue. In this thesis, a detailed characterization of the FBR to intraneural electrodes has been performed, in order to determine feasible therapeutic strategies to reduce the FBR and to improve the long-term function of chronic implanted intraneural electrodes. Our results show that the immune infiltration in the nerve peaked after two weeks of implant, without differences between two polymers intended to be used as electrode substrate (i.e., polyimide and Parylene C). However, the tissue deposition around both polymers evolved differently at chronic time points. While the capsule around polyimide devices peaked after two weeks and was stabilized after that up to 8 months, the capsule around Parylene C devices had a first peak at week 2 and it continued increasing after a resting period of 4-8 weeks to reach a second maximum at week 16. Molecular analysis of implanted nerves showed no differences between the FBR to both polymers in the inflammatory and tissue remodeling studied factors. The two main phases described in the FBR in peripheral nerves have determined possible therapeutic strategies to reduce this reaction. Among the several drugs tested, only dexamethasone significantly reduced the infiltration of macrophages and the thickness of the capsule around both polymers. Moreover, dexamethasone treatment improved the long-term function of transversal intraneural electrodes, particularly in terms of stimulation properties. In conclusion, the FBR to intraneural devices shows a similar pattern than the reported in other host tissues such as the subcutaneous and the peritoneal spaces. Moreover, differences in the FBR between polyimide and Parylene C have been observed, which would rule Parylene C out as a substrate for chronically implanted intraneural electrodes. The FBR characterization has allowed testing several therapeutic strategies to reduce this response, such as dexamethasone. In fact, dexamethasone treatment has improved the outcome of chronic implanted intraneural electrodes, may be due to a reduction in the cellular infiltration and tissue deposition.
