4-in-1 TENS EMS IFC Russian Stimulation Device with 60 Modes & 120 Intensity Levels for Muscle & Nerve Comfort | Lersk

This professional-grade electrotherapy device combines four distinct electrical stimulation technologies into one unit — TENS, EMS, Interferential Current (IFC) at 4000Hz, and Russian Stimulation (RUSS) at 2500Hz. With 60 pre-programmed modes, fully customizable parameters, and dual independent channels, it delivers clinical-level precision for daily muscle comfort, recovery, and wellness routines at home.

Four Therapy Technologies

TENS — Transcutaneous Electrical Nerve Stimulation 23 fixed + 2 fully adjustable programs. Low-frequency electrical pulses designed to target nerve pathways and support comfort in areas including the back, knees, shoulders, ankles, wrists, and elbows.

EMS — Electrical Muscle Stimulation 13 fixed + 2 fully adjustable programs. Designed for pre-training activation, post-training recovery, muscle toning, and endurance support. Adjustable ramp up, contraction, ramp down, and relaxation timing for precise muscle engagement cycles.

IFC — Interferential Current (4000Hz) 8 fixed + 2 adjustable programs. Medium-frequency interferential current designed to reach deeper tissue layers — supporting circulation, tissue comfort, and deeper muscle stimulation including pelvic floor muscles.

RUSS — Russian Stimulation (2500Hz) 8 fixed + 2 adjustable programs. Medium-frequency stimulation designed to support muscle strengthening, endurance, and recovery — particularly suited for athletic rehabilitation and post-training muscle support.

Fully Customizable Parameters

Every therapy mode can be fine-tuned to your exact needs:

• Pulse frequency: 1–800Hz (TENS/EMS) / 2000–4150Hz (IFC/RUSS)
• Pulse width: 50–300μs in 1μs steps
• Intensity: 0–120mA in 120 levels
• Session timer: 5–90 minutes in 1-minute steps
• Ramp up: 1–9 seconds
• Contraction time: 1–60 seconds
• Ramp down: 1–9 seconds
• Relaxation time: 1–60 seconds
• Cycle time (IFC/RUSS): 5–60 seconds

Dual Independent Channels Channels A and B operate completely independently — set different modes and intensity levels on each channel simultaneously for targeted treatment across two separate body areas in a single session.
