In recent years, the electroencephalography (EEG) brain-computer interface (BCI) has been researched in the area of upper-limb prosthesis control due to the promise of being able to record neurological signals which follow activation patterns in the cortex directly from the brain with non-invasive electrodes. This is seen as a way of bypassing the limitation posed by acquiring neuromuscular signals predominantly with electromyography (EMG) directly from the stump, which possesses residual limb anatomy post-amputation. In this study, the sequential forward selection algorithm to form a 10-optimal-channel representation, alongside an extended signal feature vector was applied, to investigate the motion intent decoding performance of EMG-only, EEG-only, and a fused EMG-EEG sensing configuration for four transhumeral amputees with varying stump lengths. The results showed a considerable improvement for the EMG-only configuration with the advanced feature vector, but only a small increase for the EEG-only, and thus a marginal improvement when information from both signals was fused together. This is likely due to the EEG requiring a greater number of channels spread across the skull to provide a reliable intent decoding. Further work will now involve optimisation studies to find a greater representation of electrode representation and parsimony, to minimise the number of channels while boosting motion intent decoding accuracy.

“…Better biocompatibility can be achieved by surface modifications of PLA [48], [49]. Furthermore, surface coatings with inert materials and making cross-linked PLA with other polymers can increase degradation time and that makes PLA a splendid prosthetics material candidate [50]- [53]. In this study, it used with commercially available biomaterials, PLA filaments and VC model which are produced by 3D printer were discussed.…”

This study aims to develop and demonstrate a new method of creating polymeric vocal cord (VC) models via 3D printing to reduce model production time, increase sound efficiency, and lay the groundwork for future models using more realistic geometric and functional biomaterials. For this purpose, it is to produce a poly (lactic acid) (PLA) based VC implant using a 3D printer as a special design according to the patient's vocal structure. In this study, VC 3D PLA implant (VC3DPLAI), VC stretch piece (measured = 35 mm length), fixed to thyroid cartilage VC (cartilage length = 12 mm) and titanium (Ti64) springs pieces are expected to be produced as a patient-specific implant It is composed of three different biomechanical designs. When you compare this implant with other biomaterials, the VC3DPLAI provides personal convenience compared to complex models and allows unlimited time-cost competition.

“…One of the members suffers from a physical disability that was present at birth, leaving only 12 cm below the elbow joint. This condition is referred to as a transradial amputee, which means the loss of a part below the elbow joint [4][5] [6]. Although the individual is still of productive age (36 years), this condition has resulted in an inability to work and a decrease in self-confidence when socializing in the community.…”

Many people with physical disabilities, especially transradial amputees, face difficulties in performing daily activities and have low self-esteem due to the lack of affordable and functional prosthetic hands. The aim of this community service program is to apply 3D printing technology in making prosthetic hands for the members of the Indonesian Physical Disability Association (PPDFI) branch in Surabaya. The method consists of four steps: (1) measuring the physical parameters of the amputees, such as the circumference and length of the residual limb, (2) designing and printing the prosthetic hand using 3D software and printer, (3) testing the mechanical and functional performance of the prosthetic hand, such as the ability to open and close, and (4) providing counseling and mentoring to the amputees to restore their confidence and evaluate their usage. Result: The result of this program is the availability of a low-cost and open-source prosthetic hand for the transradial amputees, which can help them to perform basic activities such as driving, holding a phone, and grabbing a bottle. The prosthetic hand can also be customized according to the needs and preferences of the amputees, such as the color or design. Conclusion: The conclusion of this program is that 3D printing technology can be used to create a functional and affordable prosthetic hand for the transradial amputees, which can improve their quality of life and self-esteem. The program also provides education and guidance to the amputees and the community about the benefits and risks of using prosthetic hands.
