Abstract

Stroke merupakan penyebab kematian kedua dan disabilitas ketiga di dunia, dengan peningkatan 10,9 per seribu penduduk di Indonesia pada 2018. Hemiplegia akibat stroke mengakibatkan gangguan berjalan yang tidak simetris dan tidak stabil. Rehabilitasi sangat penting untuk membantu penderita hemiplegia mengembalikan kemampuan berjalan. Penelitian sebelumnya menunjukkan stimulasi listrik efektif untuk pemulihan mobilitas tubuh bagian bawah, tetapi hanya berfokus pada hip dan ankle joint. Penelitian ini meninjau sistem rehabilitasi berbasis stimulasi listrik pada segmen thigh, menunjukkan interaksi antara hip dan knee joint dalam mendukung berat badan dan keseimbangan saat berjalan. Menggunakan Functional Electrical Stimulation (FES) dengan Fuzzy Logic Controller (FLC) berbasis cycle-to-cycle control, penelitian ini membantu penderita hemiplegia mengembalikan gerakan fisik dan kontraksi otot seperti Iliopsoas, Rectus Femoris, Vastus Lateralis, Bicep Femoris Long Head, dan Bicep Femoris Short Head. Fuzzy Logic Controller menghasilkan output berupa stimulation burst duration, mengatur lama aktifnya 3 channel FES untuk menstimulasi otot target. FLC1 mengatur hip flexion dengan Maximum Hip Flexion pada Swing Phase (MHFsw) sebesar (27.6±2.3)° dan Hip Flexion pada Initial Contact (HIC) sebesar (25.2±1.5)°. FLC2 mengatur knee extension dengan Maximum Knee extension pada Swing Phase (MKEsw) sebesar (15.1±1.7)° dan Maximum Knee flexion pada Swing Phase (MKFsw) sebesar (55.3±1.9)°. Dari 20 siklus, ketercapaian siklus hip flexion adalah 30%, hip joint angle saat initial contact 35%, knee extension 80%, dan knee flexion 15%. Pada penelitian selanjutnya, dapat digunakan kabel connector yang kokoh, alas kaki yang mendukung deteksi gait event, wadah custom untuk modul, komponen SMD yang lebih ringan, serta optimalisasi mikrokontroler STM32H747 dengan program Dual Core M4 dan M7.

Stroke is the second leading cause of death and the third leading cause of disability worldwide, with an increase of 10.9 per thousand population in Indonesia in 2018. Hemiplegia caused by stroke results in asymmetrical and unstable walking. Rehabilitation is crucial to help hemiplegic patients regain their walking ability. Previous research has shown that electrical stimulation is effective for the recovery of lower body mobility, but it has mainly focused on the hip and ankle joints. This study reviews a rehabilitation system based on electrical stimulation targeting the thigh segment, demonstrating the interaction between the hip and knee joints in supporting body weight and balance during walking. Using Functional Electrical Stimulation (FES) with a Fuzzy Logic Controller (FLC) based on cycle-to-cycle control, this study assists hemiplegic patients in restoring physical movements and muscle contractions such as Iliopsoas, Rectus Femoris, Vastus Lateralis, Bicep Femoris Long Head, and Bicep Femoris Short Head. The Fuzzy Logic Controller produces output in the form of stimulation burst duration, regulating the active duration of 3 FES channels to stimulate the target muscles. FLC1 controls hip flexion with Maximum Hip Flexion during the Swing Phase (MHFsw) of (27.6±2.3)° and Hip Flexion during Initial Contact (HIC) of (25.2±1.5)°. FLC2 controls knee extension with Maximum Knee Extension during the Swing Phase (MKEsw) of (15.1±1.7)° and Maximum Knee Flexion during the Swing Phase (MKFsw) of (55.3±1.9)°. From 20 cycles, the achievement of hip flexion cycles was 30%, hip joint angle during initial contact was 35%, knee extension was 80%, and knee flexion was 15%. In future research, robust connector cables, footwear that supports gait event detection, custom module housings, lighter SMD components, and optimization of the STM32H747 microcontroller with Dual Core M4 and M7 programs can be utilized.
