Recent Advances in Myoelectric Control for Finger Prostheses for Multiple Finger Loss

The loss of one or multiple fingers can lead to psychological problems as well as functional impairment. Various options exist for replacement and restoration after hand or finger loss. Prosthetic hand or finger prostheses improve esthetic outcomes and the quality of life for patients. Myoelectrically controlled hand prostheses have been used to attempt to produce different movements. The available articles (original research articles and review articles) on myoelectrically controlled finger/hand prostheses from January 1922 to February 2021 in English were reviewed using MEDLINE/PubMed, Web of Science, and ScienceDirect resources. The articles were searched using the keywords “finger/hand loss”, “finger prosthesis”, “myoelectric control”, and “prostheses” and relevant articles were selected. Myoelectric or electromyography (EMG) signals are read by myoelectrodes and the signals are amplified, from which the muscle’s naturally generated electricity can be measured. The control of the myoelectric (prosthetic) hands or fingers is important for artificial hand or finger movement; however, the precise control of prosthetic hands or fingers remains a problem. Rehabilitation after multiple finger loss is challenging. Implants in finger prostheses after multiple finger loss offer better finger prosthesis retention. This article presents an overview of myoelectric control regarding finger prosthesis for patients with finger implants following multiple finger loss.

The Prosthetic Rehabilitation of a partially amputated finger using a silicon prosthesis: A case report

: Loss always has a negative impact on an individual which engraves a feeling of incompleteness in many. Loss of anybody part creates an obstruction in the normal functioning of the body. Mostly the appendages such as arms, fingers, etc have a very important role in routine life which can restrict the living psychologically, functionally, and socially. The goal in rehabilitating a body part should be to create a substitute that is indistinguishable from adjacent and contralateral counterparts. Therefore maxillofacial prosthodontics is not only science but also an art. The present article is a case report of a person with a missing finger briefing the fabrication methodology of a custom-made silicone finger prosthesis.

Analysis on Making of Finger Prosthesis using Amputation Surgery Method

India is a vast country with a large number of individuals in the community with various disabilities. It had been estimated that there are roughly 0.62 amputees in India per thousand population. This translates to close to more than one million individuals with amputations. Digital amputation is a common injury. This very often results in extensive functional disability and a substantial psychological impact. More importantly, the outcome of digital dysfunction is detrimental to the patient's daily activities, such as buttoning a shirt or unlocking a door. Therefore, the overall goal for these patients is to rebuild a finger with the restoration of normal function, stability, length, and sensation. Prosthetic rehabilitation of amputated fingers is an attempt to rehabilitate aesthetics and limitedly function. A prosthesis will be a counterfeit body part that replaces a few of the work and presence of the absent a major aspect. The kind of your prosthetic hand, finger alternately arm will rely on upon the area Furthermore period for your remaining finger or hand Also your practical Also lifestyle necessities. It is critical with impart those exercises that you feel need aid. The separable die allowed the silicone to flow into narrow spaces. Once the mould is filled with silicone, the flask is closed and pressure is applied slowly.

Design of a Body-Powered Finger Prosthesis from Medical Images and Kinematic Analysis

With the advancement of technology, many prosthesis were developed to improve the life standard of a person who lost one or more limb. One of the most common limb loss is finger lose. Many finger prosthesis were developed to imitate the functionality of natural human fingers. But most of them are not personalised (does not fit perfectly to the user) and/or not easy to apply. Some finger prosthesis needs surgical operation to apply. The aim of this study is to design and manufacture accessible and sustainable finger prosthesis that is easy to apply and personalised. In this study, hand skeleton structure was modelled from computerized tomography images. Distal and middle phalanx bones were removed to show finger loss. Personalised finger prosthesis that fits perfectly to the user was designed on the hand skeleton structure. By using kinematic analysis, finger prosthesis movement capabilities are determined and general mathematic model was developed to be used in other patients. Before production, newly designed finger prosthesis movement was analysed and model was optimised with the result of the analysis. Finally, the gripping ability of the prosthesis that was produced and its similarity to the natural finger mechanical structure were confirmed by experiments and measurements.
