Difficulty detecting spontaneous activity on EMG due to spasticity
💚 healthpersonal problemSingle report ●●●●●
The user asks if spasticity in patients can hide spontaneous muscle activity during electromyography (EMG) because the constant muscle hyperactivity creates noise that may mask diagnostic markers of denervation.
What people do today
- Applying frequency filters to EMG signals
- Attempting to induce muscle relaxation
🔧 Fix this
Ideas a builder, maker or community group could start on:
- Develop an AI-based signal processing algorithm that differentiates between spasticity-induced noise and denervation-related spontaneous activity patterns.
- Create a standardized database of EMG frequency profiles for spastic muscles to help clinicians better calibrate their filtering equipment.
- Design a specialized EMG electrode array that uses spatial filtering to isolate localized spontaneous activity from global spastic muscle contractions.
Real voices
“spastic muscles are constantly hyperactive. This results in a noise and continous activity on EMG even when the patient is resting”
