Background:
- Upper motor neurone (UMN) paralysis presents significant functional deficits.
- Restoring function requires innovative therapeutic approaches.
- Electrical stimulation (ES) offers a potential avenue for functional recovery.
Observation:
- This review synthesizes current knowledge on ES for UMN paralysis.
- It details the physiological principles, electrophysiology, and biomaterials involved in ES delivery.
- Adverse effects and key concepts like electrode application, stimulus parameters, muscle fatigue, and control are examined.
Findings:
- ES utilizes metal electrodes to deliver charge to living tissues, requiring careful consideration of biomaterials and electrophysiology.
- Effective application involves optimizing electrode placement, stimulus parameters, and managing muscle fatigue.
- Clinical applications primarily focus on restoring function in upper and lower limbs.
Implications:
- Understanding ES principles is crucial for developing effective rehabilitation strategies for UMN paralysis.
- Further research into biomaterials and stimulation control can enhance therapeutic outcomes.
- The review highlights the current landscape of commercial ES products for clinical use.
