URSA™ E-STIM4
The Professional EMS & TENS Electrotherapy System is a clinic-grade electrical stimulation device designed for physical therapy, rehabilitation, pain management, and muscle training. It combines Electrical Muscle Stimulation (EMS) and Transcutaneous Electrical Nerve Stimulation (TENS) in one focused, easy-to-use platform, without unnecessary or misleading modalities.
This system is built for clinics that want reliable stimulation, clear controls, and predictable results.

Stimulation Modes
CP — Continuous Pulse
• Constant, steady pulse output
• Predictable stimulation behavior
• Typical uses:
◦ Basic EMS activation
◦ Standard TENS sessions
RS1 / RS2 — Rhythmic Stimulation
• Alternating contraction–relaxation patterns
• Two rhythm intensities:
◦ RS1 — slower rhythmic stimulation
◦ RS2 — faster, more intensive rhythmic stimulation
• Typical uses:
◦ Muscle strengthening
◦ Functional rehabilitation
◦ Post-exercise recovery
DF1 / DF2 — Dynamic Frequency
• Automatic frequency variation during treatment
• Designed to reduce nerve accommodation
• Two dynamic profiles:
◦ DF1 — mild frequency variation
◦ DF2 — wider frequency variation
• Typical uses:
◦ Long treatment sessions
◦ Chronic pain protocols
◦ Sensitive patients
