Abstract

Son yıllarda, Akışkan Zaman Sabiti (AZS) sinir ağları, karmaşık, zamana bağlı verileri doğru bir şekilde modelleme konusundaki olağanüstü yetenekleri nedeniyle büyük ilgi görmüştür. Çeşitli alanlardaki uygulamaları araştırılmış olsa da elektromiyografi tabanlı kas yorgunluğu veya sakatlık tespiti için AZS Sinir Ağlarının kullanılma potansiyeli araştırılmamıştır. Bu araştırmanın birincil amacı, AZS sinir ağının bu alana özgü zorlukları ele almadaki etkinliğini göstermek ve potansiyel avantajlarına dair yeni bilgiler sunmaktır. Bu hedefi gerçekleştirmek için, hasta muayeneleri sırasında elde edilen EMG sinyallerini analiz etmek için bir AZS sinir ağı kullandık. Toplanan sinyallerden, Ortalama Mutlak Değer, Dalga Biçimi Uzunluğu, Sıfır Geçişleri, Eğim İşareti Değişiklikleri ve Merkez Frekansı dahil olmak üzere beş özelliği hesapladık. Bu özellikler, AZS sinir ağı için girdi olarak kullanıldı. Ağın zamansal verilere dayalı olarak değerleri tahmin etme yeteneği, sinir hasarı veya kas işlev bozukluğunun göstergesi olan sinyal değişikliklerini hassas bir şekilde izlemesini sağladı. EMG sinyallerinden kas yorgunluğunu tespit eetmede AZS sinir ağının performansını geleneksel yöntemlerle ve diğer sinir ağı tabanlı tekniklerle karşılaştırdık. Deneysel sonuçlarımız, AZS sinir ağının %99,72'lik yüksek bir doğrulama doğruluğu elde ettiğini ve bunun kas sakatlığını belirlemedeki etkinliğini gösterdiğini ortaya koymaktadır. Bu bulgular, AZS sinir ağlarının geleneksel yaklaşımlardan daha iyi performans gösterme potansiyeline sahip olduğunu ve EMG tabanlı kas yorgunluğu tespitinde başarılı olduğunu göstermektedir.

A novel Approach for Muscle Fatigue Disorders Detection Using EMG Based Time-Constant Neural Networks

Abstract

In recent years, Liquid Time-Constant (LTC) Neural Networks have gained substantial interest due to their exceptional ability to accurately model complex, time-dependent data. Although their applications in various fields have been explored, the potential of utilizing LTC Neural Networks for electromyography-based muscle fatigue or disability detection has not been investigated. This research aims to showcase the effectiveness of LTC Neural Networks in addressing challenges unique to this domain and to offer new insights into its potential advantages. We employed an LTC Neural Network to analyze EMG signals obtained during patient examinations to accomplish this objective. We calculated five features from the collected signals, including Mean Absolute Value (MAV), Waveform Length (WL), Zero Crossings (ZC), Slope Sign Changes (SSC), and Center Frequency (CF). These features were used as input for the LTC Neural Network. The network's ability to predict values based on temporal data enabled it to precisely monitor signal changes indicative of nerve damage or muscle dysfunction. We compared the performance of the LTC Neural Network with traditional methods and other neural network-based techniques in detecting muscle fatigue from EMG signals. Our experimental results reveal that the LTC Neural Network achieved a high validation accuracy of % 99.72, indicating its effectiveness in identifying muscle disability. These findings suggest that LTC Neural Networks have the potential to outperform conventional approaches and provide successful results in the field of EMG-based muscle fatigue detection.
