Full programme configuration
MUSCLE INTELLIGENCE TECHNOLOGY
- 4 functions on all 4 channels: Mi- Scan, Mi-Tens, Mi-Range, Mi-Action (Active session with a voluntary contraction detected by the device to start the stimulation). 2 Mi-Cables included.
2+2

SKIP
- Manage the session time and move directly to the next phase (recovery) when needed.
MOTOR POINT PEN
