Abstract

Stroke adalah penyakit yang menyebabkan hemiplegia yang mana menyebabkan kelumpuhan pada satu sisi tubuh yang mana menyebabkan melemahnya kemampuan otot sehingga dapat mengubah kemampuan berjalan seseorang. Maka dari itu rehabilitasi dengan stimulus listrik merupakan salah satu cara yang tepat untuk mengembalikan kelumpuhan atau kesulitan mobilitas yang diakibatkan stroke. Dengan penggabungan functional electrical stimulation (FES) dan gerakan berjalan serta sistem sensor untuk mengukur sudut dari gerakan berjalan pada ankle joint dapat memberikan rehabilitasi gerakan berjalan pada lower limb yang sesuai. Stimulasi untuk mendeteksi stance dan swing pada gait cycle pada otot Tibialis Anterior dan Gastrocnemius dapat memaksimalkan pemulihan melemahnya otot. Pengujian gaya berjalan dimana sudut capaian pada lower limb joint serta error yang akan menjadi input Fuzzy Logic Controller dan menghasilkan durasi stimulasi FES ankle joint yang menunjukkan bahwa restorasi stance dan swing phase pada ankle joint bekerja. Sehingga stimulasi FES yang diberikan sudah dapat bekerja. Dalam hasil penelitian, FLC terbukti efektif dalam mengendalikan ankle joint dari cycle-to-cycle control dalam proses berjalan. Dengan menggunakan joint angle parameter lebih efektif dalam menstimulasi otot yang ditargetkan. Pada gerakan ankle dorsiflexion dapat dilihat dari parameter Maximum Ankle Dorsiflexion at Swing Phase (MADsw) mendapatkan hasil setelah stimulai sebesar (5,6±1,06°) yang melebihi sudut target 4,9°. Pada gerakan ankle plantarflexion dapat dilihat dari parameter Maximum Ankle Plantarflexion at Swing Phase (MAPsw) mendapatkan hasil setelah stimulai sebesar (-18,6±1,56°) yang melebihi sudut target -16,4°.

Stroke is a disease that causes hemiplegia which causes paralysis on one side of the body which causes weakening of the ability of the muscles so that it can change a person's ability to walk. Therefore, rehabilitation with electrical stimulus is one of the right ways to restore paralysis or mobility difficulties caused by stroke. By incorporating functional electrical stimulation (FES) and walking movements as well as a sensor system to measure the angle of the walking movement at the ankle joint, it can provide appropriate rehabilitation of walking movements at the lower limb. Stimulation to detect stance and swing in the gait cycle in the Tibialis Anterior and Gastrocnemius muscles can maximize the recovery of muscle weakness. The gait test where the achievement angle at the lower limb joint and the error will be the input of the Fuzzy Logic Controller and produce the FES ankle joint stimulation duration which shows that the restoration of the stance and swing phase of the ankle joint is working. So that the FES stimulation given can work. In the research results, FLC proved to be effective in controlling the ankle joint from cycle-to-cycle control in the process of walking. Using the joint angle parameter is more effective in stimulating the targeted muscles. In the ankle dorsiflexion movement, it can be seen from the Maximum Ankle Dorsiflexion at Swing Phase (MADsw) parameter that the result after stimulation is (5.6 ± 1.06°) which exceeds the target angle of 4.9°. In the ankle plantarflexion movement, it can be seen from the Maximum Ankle Plantarflexion at Swing Phase (MAPsw) parameter that the result after stimulation is (-18.6 ± 1.56°) which exceeds the target angle of -16.4°.
