This study introduces a microcomputer two-channel EMG monitor for long-term muscle activity tracking. The device aids in analyzing muscle activity, particularly for estimating spasticity in spinal cord injury patients.

Area of Science:

  • Biomedical Engineering
  • Neuroscience
  • Rehabilitation Technology

Background:

  • Long-term monitoring of muscle activity is crucial for understanding neuromuscular conditions.
  • Existing methods may have limitations in duration and data analysis capabilities.
  • Spasticity assessment in spinal cord injury patients requires reliable and continuous EMG data.

Purpose of the Study:

  • To describe a novel microcomputer two-channel EMG monitor for extended duration recordings.
  • To present the method for applying this device for muscle activity monitoring.
  • To demonstrate its utility in assessing spasticity in complete spinal cord injury.

Main Methods:

  • Development of a microcomputer-based two-channel EMG monitor.
  • Utilizing surface electrodes for non-invasive muscle activity recording.
