Abstract

This study analyzes the mechanical performance of femoral bone implants using two types of materials, namely Alloys and Cobalt Chromium Alloys, as well as two variations in implant length (72 mm and 24 mm, and 80 mm and 20 mm). Simulation was conducted using the Finite Element Method (FEM) to evaluate mechanical parameters, such as directional deformation, equivalent stress, maximum principal stress, and minimum principal elastic strain. The analysis results show that the Cobalt Chromium Alloys material has smaller deformation compared to the Alloys, indicating better stiffness and load-bearing capacity. However, the maximum principal stress value is higher in Cobalt Chromium Alloys, indicating a greater risk of stress concentration. Meanwhile, a longer implant length shows a more even stress distribution compared to a shorter length. This study provides important insights into the influence of material and implant length on its mechanical performance, and can serve as a basis for designing optimal implants for specific medical needs

Abstract

This research aims to design and test the effectiveness of the Foot Reflection-Relaxation Stimulator (FRRS), which combines electrical and magnetic stimulation as a reflexology therapy method to reduce pain caused by fatigue. FRRS is designed to stimulate reflex points in the feet by applying principles of physics such as static magnetic fields and Lorentz force, which are expected to enhance blood circulation and relax tense muscles. The testing was conducted on 25 healthy male participants who experienced leg fatigue after traveling a distance of 20 km. Pain levels were measured using the Numerical Rating Scale (NRS) before and after treatment with FRRS. The results showed a significant decrease in pain scale, from an average of 7 before treatment to 3.12 after treatment. The use of FRRS has proven effective in reducing pain due to fatigue in the legs, which is believed to be due to increased blood circulation and muscle relaxation. Thus, FRRS can be a practical and efficient solution to improve the quality of life for individuals who often experience fatigue and pain in their legs.
