In my experience, after buying a device users most often regret three things: they got too few programs, a single-channel device, or electrodes that don’t last. This article helps you avoid those mistakes and choose a device that fits your complaint.
Key idea
Choosing a TENS depends on your complaint and how often you will use it: for occasional home pain relief an entry-level model is enough (e.g. Dolito); for daily use and treating multiple body areas a mid-range 2-channel device is recommended (e.g. Globus Elite SII or TensCare UniPro); for users with chronic, multiple issues the multifunctional Genesy series is the solution.
Six main points when choosing a TENS
| Consideration | What it means | Why it matters |
|---|---|---|
| 1. Number of channels | 1, 2 or 4 channels (1 channel = 2 electrodes) | 2-channel: two body areas can be treated simultaneously. 4-channel: for covering large muscle groups. |
| 2. Number of programs | Entry: 4–8, mid: 10–25, premium: 50+ programs | More programs = more adjustment options. Useful to avoid habituation. |
| 3. Impulse quality | Precise square pulse vs. distorted waveform | A precise impulse feels more comfortable at the same intensity. |
| 4. Current strength | Maximum output current (mA), typically 60–100 mA | Higher maximum allows stronger stimulation for sensitive or intense settings. |
| 5. Multifunction | Only TENS, or TENS+EMS, MENS, IF, iontophoresis | If you have multiple types of complaints, it's worth getting broader functionality. |
| 6. Other (display, battery, cables) | Display size, rechargeable battery vs. replaceable cells, wireless | Comfort for long-term use. |

Typical models: Globus Genesy 600, Genesy 1500, Genesy 3000.
Program types – which should you use?
Even if your device has 4 or 50 programs, TENS protocols fall into four main families (see the TENS pillar article):
Strong tingling sensation; based on the gate-control theory it can help reduce pain signals. Recommended for acute pains (sprain, muscle soreness) or for beginners. This is the most commonly used program.
Slower program accompanied by small muscle contractions. May promote the release of endogenous opioids (endorphin, enkephalin), giving a longer-lasting effect. Useful for chronic pain – e.g. fibromyalgia, prolonged low back pain.
1–4 bursts per second, with a high frequency inside each burst. Combines gate-control and endorphin-mediated effects. Many users find it more comfortable than pure low-frequency stimulation.
Frequency, amplitude and pulse width are continuously varied. This is the key to avoiding habituation during long-term use. The 2003 Bjordal et al. paper (Eur J Pain) discusses TENS dosing rules, including the importance of parameter variation. For chronic pain, modulated programs are the basis for effective long-term use.
Worked great the first days, then faded?
Many users notice that TENS significantly relieved pain in the first week or two, then the effect gradually decreased. This is the phenomenon of habituation: the nervous system gets used to the constant stimulus and responds less.
The solution is not a new drug or a more expensive device, but parameter variation:
Avoiding habituation
- Alternate programs – don’t stick to a single frequency. One day conventional, another day acupuncture-like, a third day burst.
- Use a modulated program – these continuously change parameters, reducing habituation.
- Respect treatment timeframes – one session 20–45 minutes, 2–3 times daily; continuous use for many hours usually does not increase effectiveness.
- Rest days – 1–2 days off per week “re-sensitizes” the nervous system.
- Vary electrode placement – don’t place pads on exactly the same spot every time.

Simple decision process
Ask yourself these 4 questions:
- How often will I use it? 1–2× weekly → entry. Daily → mid. Several times daily across multiple areas → premium.
- Only pain relief, or muscle strengthening too? TENS only → entry. TENS+EMS → mid. Complex (TENS+EMS+microcurrent+IF) → premium / multifunctional.
- One body area, or several simultaneously? One → 1–2 channels. Multiple → 2–4 channels.
- Who will use it? Only me → focused model. Other family members will use it too → multifunctional + many programs.
More help: the TENS, EMS and MENS differences article helps decide which method suits your complaint.
Before you buy – check the contraindications
TENS treatment is not suitable for certain conditions. Details: general electrotherapy contraindications.
- Pacemaker, ICD or other active implant
- Malignancy in the area to be treated
- Pregnancy (treatment in the lower abdomen and lumbar area is contraindicated)
- Acute fever, infection, open wound in the treatment area
- Acute deep vein thrombosis (within 3 months)
Frequently asked questions
Low-priced TENS devices (5–15k HUF) always involve compromises: few programs, poor impulse quality, less durable electrodes, shorter lifespan. If you plan occasional use and have minor complaints without chronic problems, they can work. For chronic, daily use it’s worth choosing a branded device with CE certification in at least the 30–40k HUF range.
1 channel (2 electrodes) is enough if you want to treat only one area at a time and perform treatments sequentially. Most users choose 2 channels: to treat two areas simultaneously (e.g. both knees, both calves) or to cover a larger area (e.g. 4 electrodes around the back/lower back). Choose 4 channels if you regularly stimulate large muscle groups (quadriceps, gluteus, back) with EMS or have multiple joint problems.
The ideal TENS impulse is a clean square wave: fast rise and fall, constant amplitude. Cheaper devices have waveforms that do not approach this (distorted, rounded peaks, longer transitions), which can feel more unpleasant at the same set current. Professional devices (e.g. the Globus Genesy series) deliver precise impulse shapes that are more comfortable during long treatments and significantly affect effectiveness.
Rechargeable (Li-Ion) devices are more convenient, USB-chargeable, and cheaper over time. Battery life is typically 2–4 years with regular use. Replaceable-cell (AA/AAA) devices have the advantage that you don’t have to wait for charging; if cells run out you can simply replace them. Entry-level devices often use replaceable cells, while mid and upper-range devices typically use rechargeable batteries.
Branded CE-certified devices (Globus, TensCare, MTR) are typically designed for 8–10 years of service life. Electrodes naturally need more frequent replacement (after some 15–20 adhesions). The battery may be replaceable every 2–4 years. Details about electrodes: electrode selection.
Wireless TENS devices (e.g. smartphone-controlled modules attached to small pads) are more convenient when moving – they can be worn while running, training or working from home. Their disadvantages: smaller battery (shorter runtime), less manual control, higher price. They don't always replace a wired device and are more of a complementary option. For a home "basic kit" it's advisable to start with a classic wired device.
