Insights into motor impairment assessment using myographic signals with artificial intelligence: a scoping review
This scoping review synthesizes recent advancements in the use of myographic signals with Artificial Intelligence (AI) for objective motor impairment assessment. It highlights the potential of AI to overcome limitations in traditional clinical evaluations by providing more precise and tailored insights into muscle function and pathology. The review identifies common measurement modalities, AI approaches, and demographic biases, offering crucial directions for future research and clinical translation.
Executive Impact & Strategic Imperatives
Integrating AI with myographic signals offers a transformative approach to motor impairment assessment, promising enhanced objectivity, precision, and efficiency in clinical diagnostics and rehabilitation. This technology can lead to earlier and more accurate diagnoses, personalized treatment plans, and continuous monitoring, significantly improving patient outcomes and reducing healthcare costs associated with subjective or delayed assessments. For enterprises in healthcare, medical device manufacturing, and rehabilitation technology, this represents a significant market opportunity to develop and deploy cutting-edge solutions that can revolutionize patient care.

Measurement Modalities
The review found that surface electromyography (sEMG) is the most prevalent myographic measurement modality, accounting for 79.5% of all reviewed studies. Other modalities like sonomyography (SMG), mechanomyography (MMG), force myography (FMG), and intramuscular EMG (iEMG) are also used but less frequently. In patient-involved studies, EMG modalities collectively dominated 88% of applications, highlighting their clinical relevance.
AI Application & Tasks
AI models were predominantly used for classification tasks (78.4%), focusing on identifying gestures, movements, activities, and diagnosing clinical conditions or severity levels. Regression tasks (21.6%) were applied for predicting assessment scores, joint angles/torques, and muscle activation levels. These applications spanned various muscle groups in upper and lower limbs, as well as the neck and torso, demonstrating broad utility.
Demographics & Biases
A significant demographic bias was observed, with a greater representation of male participants (58.6%) and healthy individuals (63.3%) compared to females and clinical populations. Age distributions also showed discrepancies, with healthy groups typically younger (20-30 years) and patient groups having a broader, older range. Geographic affiliations were concentrated in Northeastern Asia, Western Europe, and North America, indicating a need for more diverse and representative datasets to enhance generalizability.
AI Model Approaches
Machine learning with feature engineering was the predominant AI approach (90.3%), often utilizing algorithms like k-nearest neighbors (KNN), support vector machines (SVM), and neural networks (NNs) for classification. Deep learning models, especially NNs, were also common, with 64.3% of these still incorporating feature engineering. There's a critical need for transparent reporting of model complexity to assess generalizability across diverse applications.

Real-world Application: Stroke Rehabilitation
A study demonstrated myographic signals with AI can provide more direct insight into muscle activity over other modalities like IMU, improving classification accuracy for normal and pathological movement patterns. This has significant implications for tailored rehabilitation protocols, tracking recovery, and assessing intervention effectiveness more objectively.
Impact: Improved classification accuracy from 89.35% (EMG-only) to 96.06% (EMG+Kinematic Fusion) using SVM for stroke patients.
