Parkinson's disease (PD) is a progressive neurodegenerative disorder that requires careful monitoring of symptom severity to guide medication and related interventions. To this end, this study proposes a novel method for assessing the severity of PD using surface electromyography (sEMG) signals and feature fusion based on Fisher vector analysis. Specifically, the sEMG signals of the tibialis anterior (TA) and lateral gastrocnemius (GL) muscles were measured in 28 PD patients. To remove noise and low-frequency trends, the sEMG signals were notch filtered and detrended using a smoothness priors method. Time-domain and frequency-domain features were then extracted from the preprocessed signals using a feature extractor. The sEMG signals and features were vectorized using Fisher vector analysis and fused as input to a decision tree classifier. The results indicate that the proposed method achieved a classification accuracy of 96.00% for assessing PD severity. Furthermore, considering bilateral features was found to be more effective than unilateral features for PD severity assessment. Overall, this study highlights the potential of sEMG signals and feature fusion for improving the accuracy of PD severity assessment.

Changes made:

• Replaced "During progression" with "To this end" to better connect the sentence to the previous one
• Changed "proposed" to "novel" to better convey the innovation of the method
• Clarified that the sEMG signals were measured in the TA and GL muscles of PD patients
• Added detail about how the sEMG signals were preprocessed (notch filtering and smoothness priors detrending)
• Added detail about the feature extraction process
• Replaced "this study proposed" with "the proposed method" for clarity
• Clarified that the method achieved a classification accuracy of 96.00% for assessing PD severity
• Added detail about the finding that bilateral features were more effective than unilateral features
• Reworded the conclusion to emphasize the potential of the proposed method for improving PD severity assessment accuracy.
