InTENSity Select Combo II: Rechargeable TENS, NMES, Interferential & Russian Stim Device
The InTENSity Select Combo II is a rechargeable, portable, dual-channel electrotherapy device that combines TENS, NMES, Interferential, and Russian stimulation in one compact unit. It is designed for users who need more flexibility than a basic TENS unit and want one device that can support both sensory pain-modulation programs and clinician-directed muscle-stimulation programs.
With body-part presets for the neck, shoulder, hand, low back, knee, and foot, plus custom U1 programming, the Select Combo II is a practical choice for physical therapy clinics, sports medicine providers, athletic training rooms, chiropractic offices, rehab professionals, and guided home programs.
For setup, safety, charging, program selection, and troubleshooting details, read the InTENSity Select Combo II Manual. For replacement pads, compare our TENS/NMES/FES electrodes or browse the full electrotherapy electrode collection.

Four Therapy Modes Explained
| Mode | Plain-English Purpose | Typical Sensation | Best Fit |
|---|---|---|---|
| TENS | Sensory nerve stimulation for temporary pain-modulation support | Tingling, pulsing, buzzing, tapping | Pain-focused programs for areas like the low back, shoulder, knee, neck, hand, or foot |
| NMES / EMS | Motor stimulation designed to create muscle contraction | Strong contraction and relaxation rhythm | Muscle re-education, activation, and clinician-directed strengthening support |
| Interferential / IFC | Medium-frequency stimulation often used for broader pain-modulation workflows | Often feels deeper or smoother at the skin | Larger treatment regions or users who prefer interferential-style stimulation |
| Russian stimulation | Medium-frequency burst stimulation for stronger contraction cycles | Rhythmic contraction with ramp, contract, and relax phases | Muscle strengthening or re-education programs when clinically appropriate |

Product Description
The InTENSity Select Combo II DI2195 is a rechargeable, portable, dual-channel electrotherapy device with four selectable stimulation modes: TENS, NMES, Interferential, and Russian stimulation. It is designed for users who want more therapy-mode flexibility than a standard TENS unit while keeping the device compact enough for home programs, clinics, athletic training rooms, and mobile care.
TENS and interferential modes are commonly used for temporary pain-modulation support. NMES and Russian stimulation are used for muscle contraction, muscle activation, and rehab-style programs when appropriate and professionally guided. The Select Combo II includes body-part presets for the neck, shoulder, hand, low back, knee, and foot, plus U1 custom programming for trained users who need more control over treatment time, intensity, pulse rate, pulse width, ramp, contraction, relaxation, and beat-frequency settings.
Each unit includes the Select Combo II device, lead wires, four 2" x 2" electrodes, an instruction manual, a quick start guide, a rechargeable lithium battery pack, a USB cable, and a wall charger. For complete safety and operating instructions, read the InTENSity Select Combo II Manual. To find replacement pads, you can shop Balego TENS/NMES/FES electrodes or browse all electrotherapy electrodes.
Important Safety Notes
Use the Select Combo II only according to the device manual and the guidance of a qualified healthcare professional. Do not use electrotherapy over unsafe areas, on damaged skin, or with incompatible devices or accessories.
| Safety Topic | Guidance |
|---|---|
| Implanted devices | Do not use with pacemakers, implanted defibrillators, or implanted electronic devices unless specifically cleared by a qualified medical professional |
| Unsafe activities | Do not use while bathing, showering, sleeping, driving, or operating machinery |
| Unsafe placements | Avoid the head, face, front of the neck, throat, across the chest, directly over the spine, or over metal objects |
| Skin condition | Apply electrodes only to clean, dry, intact skin |
| Pad spacing | Keep pads separated; do not allow electrodes to touch each other |
| Pad movement | Turn the device off before moving or removing electrodes |
| Charging | Do not use the device while charging |
| Skin irritation | Stop use if stimulation feels burning, sharp, painful, or unusual, or if redness or irritation occurs |
| Professional supervision | Use clinician guidance for NMES, Russian stimulation, post-surgical use, weakness, neurological symptoms, or complex conditions |
Troubleshooting Guide
| Issue | Possible Cause | What to Try |
|---|---|---|
| The device will not turn on | Battery depleted or not seated correctly | Recharge battery and confirm installation |
| Weak stimulation | Low battery, poor pad contact, old electrodes, or loose lead wires | Recharge, replace pads, check wires, clean skin |
| Stinging or burning | Pad edge lifting, worn electrodes, pads too close, intensity too high | Lower intensity, replace pads, increase spacing |
| One side feels stronger | Uneven pad contact or different skin resistance | Reposition pads and check adhesion |
| The output stops | Open circuit, disconnected wire, or poor pad contact | Turn off, reconnect, then restart at low intensity |
| Device locks during treatment | Safety lock activated | Use the channel decrease button as directed in the manual |
| Pads do not stick | Old gel, dry skin, lotion, hair, or repeated use | Replace pads and prepare skin properly |
| Skin irritation | Sensitive skin, long sessions, repeated placement, worn pads | Stop use, inspect skin, rotate placement sites |
Frequently Asked Questions
What is the InTENSity Select Combo II used for?
The InTENSity Select Combo II is a portable electrotherapy device with TENS, NMES, interferential, and Russian stimulation modes. It is used for clinician-directed pain modulation and muscle stimulation programs.
Is the Select Combo II only a TENS unit?
No. It includes TENS, but it also includes NMES, Interferential, and Russian stimulation.
What is the difference between TENS and NMES?
TENS is generally used for sensory nerve stimulation and temporary pain modulation support. NMES is used to create muscle contractions for muscle activation and re-education when appropriate. For a full comparison, read Balego TENS vs. NMES.
What is interferential stimulation?
Interferential stimulation, often called IF or IFC, uses medium-frequency stimulation with a beat-frequency effect. It is often selected for broader pain-modulation style electrotherapy programs.
What is Russian stimulation?
Russian stimulation uses a medium-frequency carrier delivered in bursts. It is typically used for muscle contraction programs such as strengthening or re-education when clinically appropriate.
How many channels does it have?
The Select Combo II has two isolated channels, allowing one or two electrode-pair setups.
Is it rechargeable?
Yes. The device uses a rechargeable lithium battery pack and includes charging accessories.
Can it be used while charging?
No. Disconnect the device from the patient and do not use it while charging.
What electrodes work with the Select Combo II?
Use compatible self-adhesive electrotherapy electrodes with the correct lead-wire connection. Balego replacement options include Balego TENS/NMES/FES electrodes, DURA-STICK PLUS electrodes, and the full electrotherapy electrodes collection.
Is the Select Combo II better than the Twin Stim IV?
The Select Combo II is more versatile because it adds interferential and Russian stimulation. The Twin Stim IV is a good choice when the user only needs TENS and NMES.
When should I choose the Balego four-channel stim instead?
Choose the Balego Four Channel Stim when you need four independent channels for broader coverage, multiple treatment zones, or more electrode pairs at the same time.
Why did the output stop during treatment?
The device may detect poor pad contact, a loose lead wire, or an open circuit and reset output for safety. Check the pads, lead wires, skin contact, and battery before restarting at a low intensity.
Why does the unit lock after treatment starts?
The safety lock helps prevent accidental button presses during use. Follow the manual’s unlock instructions using the channel control buttons.
