The EMS User Program allows for individual selection of rectangular pulse parameters for electromuscular stimulation. By adjusting settings such as frequency, pulse width, rise time, and interpulse pauses, the stimulus can be tailored to the patient’s individual needs, ensuring it is both comfortable and effective. Furthermore, Stella BIO allows for the creation of electrostimulation sequences – simultaneous (simultaneous or staggered) and antagonistic muscle stimulation.

Parameter Selection Guide:

Pulse Frequency:

• Low (1-10 Hz) has a relaxing and analgesic effect.
• Medium (20-50 Hz) is optimal for inducing effective yet comfortable muscle contractions.
• High (>50 Hz) provides strong tetanic contractions but may be less pleasant for the patient.

Pulse Width (Duration):

• Longer pulses (e.g., 300-400 µs) increase stimulation effectiveness but may be less comfortable.
• Shorter pulses (e.g., 100-200 µs) are gentler but typically less effective.

Pulse Rise Time:

Increasing this time improves patient comfort, especially with higher pulse intensities.

Pause Time:

A properly selected work-to-rest ratio (e.g., 1:2 or 1:3) prevents excessive muscle fatigue.

Example: 5 seconds of work and 10 seconds of rest (1:2 ratio) allows for effective muscle stimulation while maintaining their ability to recover.

Shorter rest periods increase training intensity but may lead to earlier fatigue.

Proper selection of these parameters allows for optimal therapeutic and training results while minimizing discomfort during the treatment.
