1. Introduction

Version followed: TENS as described by NHS public information (nhs.uk, reviewed 14 February 2025) and an NHS trust pain-service leaflet (Cambridge University Hospitals, version 8, approved 28 June 2024); guideline status per NICE NG193 (published 7 April 2021, minor updates to April 2022) and NICE NG226; US device classification per FDA 21 CFR Part 882 and FDA 510(k) records; the psychological side per NICE NG193 and the British Pain Society Guidelines for Pain Management Programmes for adults (second revision, July 2019). All checked October 2026.

TENS (transcutaneous electrical nerve stimulation) is a small, battery-powered device that sends a weak electrical current through sticky pads on the skin to give temporary pain relief [source: nhs.uk TENS page]. NHS information says it may work by encouraging the release of endorphins and by stopping pain signals from nerves reaching the brain, and that it does not work for everyone [source: nhs.uk]. Johnson and Jones (2017) describe it as mild pulsed currents across intact skin that stimulate low-threshold nerves, offered by physicians, nurses, midwives and physiotherapists, usually self-administered and widely bought without prescription [source: Johnson & Jones 2017].

TENS is a device, not a psychotherapy. Physiotherapists, pain services, midwives and doctors demonstrate and advise on it, and many people buy one themselves. This guide is written for the psychotherapist working alongside them. It gives no device settings, pad positions or usage schedules: those belong to the treating clinician and the device instructions. The psychotherapist's job is to help the client use any device as one part of an active self-management plan, to support informed choices, to notice when a medical or physiotherapy review is needed, and to deliver the pain-psychology work that NICE does recommend (CBT or ACT for pain) [source: NICE NG193 1.2.3; synthesis].

How change happens, from the psychotherapist's side: in chronic pain care the aim is better function, mood and quality of life rather than pain relief alone. The British Pain Society states that pain relief "is typically not a primary aim of treatment" in pain management programmes [source: BPS PMP guidelines 2019, §3.1.3]. A device that gives short-term relief can support activity, or it can become a passive, relief-seeking habit that crowds out self-management. The therapist works to keep it in the first role [synthesis].

Guideline and regulatory status (as of October 2026)

  • NICE NG193, chronic primary pain (England, people aged 16 and over). Recommendation 1.2.6: do not offer TENS, ultrasound or interferential therapy to manage chronic primary pain, because there is no evidence of benefit [source: NICE NG193 PDF]. Chronic primary pain is pain lasting or recurring for more than 3 months, with no clear underlying condition or with pain or impact out of proportion to observable injury or disease [source: NICE NG193]. The recommendation does not directly cover chronic secondary pain (for example arthritis, endometriosis, nerve damage), which NICE leaves to the guideline for the underlying condition [source: NICE NG193]. NG193 does recommend supervised group exercise (1.2.1), considering ACT or CBT for pain (1.2.3) and, under conditions, a single course of acupuncture (1.2.5); it makes no recommendation for or against pain management programmes [source: NICE NG193].
  • NICE NG226, osteoarthritis. Recommendation 1.3.9: do not offer a list of electrotherapy treatments to people with osteoarthritis, because there is insufficient evidence of benefit [source: NICE NG226 recommendations page]. Whether the list names TENS is [uncertain]. Older NICE osteoarthritis advice, which Johnson and Jones (2017) report as recommending TENS for short-term relief, has been superseded [source: Johnson & Jones 2017; uncertain on the exact superseded guideline].
  • NICE NG59, low back pain and sciatica. Johnson and Jones (2017) report that the 2016 NICE draft advised against offering TENS for low back pain with or without sciatica [source: Johnson & Jones 2017]. The final NG59 recommendation text is [uncertain]; check the current NICE page.
  • American Academy of Neurology (US). A guideline published in Neurology on 30 December 2009 advised against TENS for chronic low back pain (three months or longer) and found it can be effective for painful diabetic neuropathy [source: AAN press release, 2009]. Whether this guideline has since been updated, reaffirmed or retired is [uncertain].
  • NHS public information lists period pain, labour pain, sports injuries and pain from conditions such as arthritis or endometriosis as uses, says TENS can help short- and long-term pain but not for everyone, and advises seeing a healthcare professional first if the cause of pain is unclear [source: nhs.uk].
  • United States (FDA). TENS for pain relief is regulated under 21 CFR 882.5890 as a Class II device; over-the-counter models are cleared by 510(k). For example, one OTC device was cleared in August 2014 for pain from sore or aching muscles of the lower back, arms or legs due to strain from exercise or normal household and work activities [source: FDA K140168]. A separate regulation, 21 CFR 882.5891, covers TENS for headache, with required labelling that contraindicates use with implanted metallic or electronic devices in the head, cardiac pacemakers or implanted or wearable defibrillators, and warns against use on the neck or chest and while bathing, sleeping, driving or operating machinery, and states that long-term effects of chronic use are unknown [source: 21 CFR 882.5891]. The text of 882.5890 itself is not drawn on here [uncertain].
  • United Kingdom and EU. NHS advice is to look for a CE or UKCA mark when buying or hiring a device [source: nhs.uk]. MHRA-specific guidance is not drawn on here [uncertain].
  • Ages. NICE NG193 covers people aged 16 and over [source: NICE NG193]. Age limits in individual device labelling were not checked; refer to the device instructions and the treating clinician [uncertain].

Contraindications and cautions as official sources state them

  • Do not use with epilepsy or a pacemaker (nhs.uk; the CUH leaflet says it is not advisable and to seek medical advice) [source: nhs.uk; CUH 2024].
  • Pregnancy: not unless a doctor or midwife advises it (nhs.uk) or under medical supervision (CUH) [source: nhs.uk; CUH 2024].
  • Do not use on irritated, broken, infected or numb skin, or on the neck, mouth or eyes [source: nhs.uk]. CUH adds that pads should not be placed around the heart because this may affect heart rhythm, and lists fainting and burns as risks of incorrect placement on the neck, eyes or mouth [source: CUH 2024].
  • Not while sleeping, in the bath or shower, or while driving or using tools or machinery [source: nhs.uk; CUH 2024].
  • Main side effect: skin irritation; stop and remove the pads if skin becomes itchy, irritated or red. nhs.uk notes redness can be harder to see on brown or black skin [source: nhs.uk].
  • CUH advises continuing usual activity and prescribed medicines and talking to the healthcare provider before changing medication [source: CUH 2024].

The psychotherapist does not assess these contraindications clinically; if any may apply, the client is referred back to the GP, physiotherapist, midwife or pain team [synthesis].

2. Framework

No source opened gives a phase structure for a psychotherapist working with a client who uses TENS. The structure below is [synthesis], built on NICE NG193's person-centred assessment and care-and-support-plan recommendations and the British Pain Society's description of pain management programmes.

Phase 1: Assessment and joining the care team (sessions 1–2, individual).

  • Goals: understand the pain, its impact and the client's current coping, including any device use; identify the treating team. NG193 asks clinicians to offer a person-centred assessment of how pain affects the person's life and that of family, carers and significant others, including mood, stressful life events, substance use, relationships and social concerns (1.1.1, 1.1.8) [source: NICE NG193].
  • Move on when: the clinical picture is clear, any contraindication or red-flag concern has been referred, and the client consents to contact with the treating team [synthesis].

Phase 2: Shared understanding and care plan (sessions 2–4).

  • Goals: psychoeducation about chronic pain and about what TENS can and cannot offer; agree a care and support plan covering priorities, goals and preferred approaches, as NG193 1.1.17–1.1.19 describe [source: NICE NG193].
  • Move on when: the client has values-based functional goals not tied only to pain scores [synthesis].

Phase 3: Active pain-psychology work (typically 6–16 sessions, individual or group) [synthesis on number].

  • Goals: CBT or ACT for pain (NG193 1.2.3), with pacing, goal setting, graded activity, cognitive and acceptance methods, sleep and flare-up planning as in the BPS components [source: NICE NG193; BPS 2019 §3.4–3.6]. Any device is placed inside this plan as a short-term aid to activity, not its centre.
  • For context: BPS reports that non-residential pain management programmes of at least 25–30 hours show efficacy, delivered over 2–10 weeks [source: BPS 2019 §3.10]. This is a team programme benchmark, not an individual-therapy session count.
  • Move on when: the client applies skills between sessions, function is improving, and reliance on passive strategies (device, rest, reassurance seeking) is stable or reducing [synthesis].

Phase 4: Maintenance, setbacks and ending (2–4 sessions, spaced).

  • Goals: a written setback plan, generalisation to daily life, and agreed routes back to the team. BPS notes that people may struggle to keep skills in the long term and recommends reorienting returners to a rehabilitation approach rather than repeating investigations and treatments [source: BPS 2019 §3.10.3–3.10.4].
  • End when: the client can manage a flare-up with their plan and knows whom to contact [synthesis].

3. Guiding principles

  • Stay in your lane on the device. Never advise on settings, pad positions, duration, buying a model or whether to start or stop; route these to the physiotherapist, midwife, GP or pain team [synthesis].
  • Report guideline status neutrally and accurately. NICE advises against offering TENS for chronic primary pain; that is not the same as saying it is harmful or that a client with chronic secondary pain should stop [source: NICE NG193; synthesis].
  • Function before relief. Goals are framed around valued activity; pain relief is welcome but not the main aim [source: BPS 2019 §3.1.3].
  • Person-centred and shared decisions. The client's priorities, goals and preferences shape the care plan [source: NICE NG193 1.1.17–1.1.19].
  • Self-management is the target. Programmes aim to improve the person's ability to manage pain-related disability and reduce reliance on healthcare [source: BPS 2019 §2.3].
  • A device can serve activity or avoidance. Ask what the device makes possible and what it replaces; that answer guides the work [synthesis].
  • No one is excluded on judgements of motivation. BPS states there are no grounds for excluding people based on age, literacy, litigation or judgements of motivation [source: BPS 2019 §1.9, §5.8].
  • One team, one message. Coordinate with the treating team so the client hears consistent explanations [source: BPS 2019 interdisciplinary framework; synthesis].
  • Safety first. Unclear cause of pain, new or changing pain, or possible contraindications go back to a healthcare professional [source: nhs.uk; synthesis].
  • Medicines belong to the prescriber. Never suggest changing pain medication because a device "helps"; CUH advises speaking to the healthcare provider before changing medication [source: CUH 2024].

4. Intervention inventory

Part A describes how TENS is supplied and used, at a descriptive level only, so you can talk about it accurately. Part B covers the psychotherapist's own interventions.

A1. How TENS is supplied and used (factual description)

  • Purpose: know what the client is doing so you can talk about it, without instructing them.
  • Description: TENS is a battery-powered unit connected by leads to adhesive pads on the skin [source: nhs.uk]. It is offered by physicians, nurses, midwives and physiotherapists, on its own or with medication, for inflammatory, neuropathic and musculoskeletal pain and in acute settings such as post-operative pain and childbirth [source: Johnson & Jones 2017]. In NHS pain services a healthcare professional demonstrates the machine and explains its use; the service can advise on buying a home unit [source: CUH 2024]. People can also buy one online or from pharmacies and electrical retailers, or hire one; NHS advice is to check with a GP or other professional first and to look for a CE or UKCA mark [source: nhs.uk]. Users adjust the device themselves. Johnson and Jones describe a learning phase, the need to troubleshoot a declining response, and some users giving up because the effort outweighs the relief [source: Johnson & Jones 2017].
  • What is deliberately not described here: settings, pad positions, session lengths and schedules. These come from the treating clinician and the device's instructions [synthesis].
  • Watch for: a device bought without professional advice when the cause of pain is unclear, or when epilepsy, a pacemaker, pregnancy or skin problems are present (see Section 1). Refer to the GP, physiotherapist, midwife or pain team [source: nhs.uk; synthesis].

A2. Guideline status by indication (factual description)

  • Purpose: answer the question "Does NICE say it works?" accurately.
  • Description: see Section 1. In short: for chronic primary pain in people aged 16 and over, NICE NG193 says do not offer TENS. For osteoarthritis, NICE NG226 says do not offer listed electrotherapy treatments; whether the list includes TENS was not confirmed [uncertain]. For low back pain, a NICE draft advised against TENS according to Johnson and Jones; the final text is [uncertain]. A 2009 AAN guideline advised against it for chronic low back pain and found it can help painful diabetic neuropathy [source: AAN 2009]. NHS public information lists period, labour, sports-injury and arthritis or endometriosis pain as uses [source: nhs.uk].
  • Watch for: clients told by a website or seller that a device "cures" pain or is "clinically proven" for their condition. Compare such claims with what the device's own clearance or labelling states (for example, an FDA OTC clearance for sore or aching muscles from strain) [source: FDA K140168; synthesis].

B1. Pain and coping assessment, including device use

  • Purpose: understand the pain's impact and the function of every coping strategy, including TENS.
  • Steps:
    1. Follow NG193's person-centred assessment: how pain affects daily life, work, relationships, mood, sleep, stressful life events and substance use, and its effect on family and carers [source: NICE NG193 1.1.1, 1.1.8].
    2. List current strategies: medicines (by name only, as reported), devices, rest, heat, activity, distraction, avoidance [synthesis].
    3. For the device, ask who recommended it, whether anyone demonstrated it, how often and in what situations it is used, what it lets the client do, and what happens when it is unavailable [synthesis].
    4. Screen mood, anxiety, sleep and suicidality as standard practice. Chronic pain with hopelessness requires a structured risk assessment and safety plan [synthesis].
    5. Identify the treating team and get consent to contact them [synthesis].
  • Example language (illustrative): "Tell me about a typical day when you use the TENS unit. What does it let you do that you couldn't do otherwise?" / "Who showed you how to use it, and who do you go back to with questions?"
  • Watch for: device use that mainly happens during rest or avoidance; increasing use with shrinking activity; use despite a listed contraindication [synthesis].

B2. Recognising when to suggest a medical, physiotherapy or midwifery review

  • Purpose: keep the client safe and the device under appropriate professional advice.
  • Steps (prompt a review when):
    • the cause of the pain is unclear, or the pain is new or has changed in character [source: nhs.uk; synthesis];
    • the client has epilepsy or a pacemaker, is pregnant, or has broken, infected or numb skin where they use it [source: nhs.uk; CUH 2024];
    • skin irritation or soreness persists, or the client reports fainting or other unexpected effects [source: nhs.uk; CUH 2024];
    • the client has other implanted electronic devices (for example a defibrillator) and has not discussed TENS with their clinician [source: 21 CFR 882.5891 for head devices; synthesis for general application];
    • the client wants to reduce or stop medication because of TENS [source: CUH 2024];
    • relief is falling away and the client is escalating use or adding devices [synthesis].
  • Example language (illustrative): "That's a question for your physio rather than me. Would it help if we wrote down what you want to ask before your next appointment?"
  • Watch for: the client asking you to "just say" whether to change something. Restate your role and help them prepare the question [synthesis].

B3. Psychoeducation about chronic pain and about the device

  • Purpose: build a shared, accurate model that supports self-management.
  • Steps:
    1. Explain that persistent pain involves the nervous system's processing, not only tissue damage, and is influenced by mood, stress, sleep and activity. BPS includes pain-science education that reframes pain as less threatening [source: BPS 2019 §3.8.3].
    2. Present TENS as NHS information does: it may give temporary relief and does not work for everyone [source: nhs.uk].
    3. State guideline status neutrally (A2), separating chronic primary pain from conditions with an identified cause [source: NICE NG193].
    4. Link back to active strategies: exercise, pacing and psychological approaches are central to NICE and BPS recommendations [source: NICE NG193 1.2.1, 1.2.3; BPS 2019].
    5. Keep education interactive and paired with practice; BPS says education alone is weak for behaviour change [source: BPS 2019 §3.8.1].
  • Example language (illustrative): "Some people find TENS gives short-term relief. NICE doesn't recommend it for the kind of long-term pain without a clear cause that you've described, so I'd see it as one possible tool, not the main plan. The plan is getting you back to the things that matter."
  • Watch for: the client hearing "NICE doesn't recommend it" as "your pain isn't real" or "you're doing it wrong". Validate and clarify [synthesis].

B4. Supporting informed consent and shared decision-making

  • Purpose: help the client make their own informed choice about TENS (and other treatments) with their clinicians.
  • Steps:
    1. Ask what they already know and what they hope the device will do [synthesis].
    2. Help them gather questions for the clinician: benefits for their condition, risks and contraindications, how they will know whether it is helping, and what else is available [synthesis].
    3. Use NG193's care-and-support-plan discussion: priorities, goals and preferred approaches [source: NICE NG193 1.1.17–1.1.19].
    4. Respect the decision. Your role is to make sure it is informed, not to make it [synthesis].
  • Example language (illustrative): "If you decide to keep using it, how will you and your physio judge whether it's earning its place?"
  • Watch for: decisions driven by desperation or marketing pressure, or expensive purchases made during a flare [synthesis].

B5. Exploring the device's function: aid to activity or safety behaviour

  • Purpose: prevent over-reliance on a passive strategy and redirect it toward activity.
  • Steps:
    1. Do a functional analysis of a recent episode: trigger, pain, thoughts, device use, what followed, longer-term effect on activity [synthesis, standard CBT method].
    2. Sort uses into two groups: "enables" (helps me walk to the shop) and "replaces" (I stay on the sofa with it on) [synthesis].
    3. Agree that the device is linked to valued activity. Do not tell the client to cut down; ask what they notice [synthesis].
    4. If use looks compulsive or anxiety-driven (checking, unable to go out without it), treat it like any safety behaviour: explore the feared outcome and plan behavioural experiments collaboratively, with the treating clinician informed [synthesis].
  • Example language (illustrative): "When the unit is on, are you more likely to be doing something or resting? Which of those fits where you want to be in three months?"
  • Watch for: the conversation turning into an argument about the device. Return to the client's goals [synthesis].

B6. Activity pacing

  • Purpose: break boom-and-bust cycles.
  • Steps:
    1. Introduce pacing as BPS defines it: an active self-management strategy for balancing time spent on activity and rest [source: BPS 2019 §3.5.4].
    2. Use a few days of activity diary to spot overactivity on good days and enforced rest after [synthesis].
    3. Set baselines by time or amount, not by pain level, and plan small, steady increases [synthesis].
    4. If the client uses TENS, discuss whether it tempts them to push past their plan on good days [synthesis].
  • Example language (illustrative): "Let's plan the activity by the clock, not by how much it hurts, so a good day doesn't cost you the next three."
  • Watch for: pacing used as a reason for further avoidance; check that activity is actually increasing [synthesis].

B7. Values and goal setting

  • Purpose: anchor treatment in function and meaning.
  • Steps: BPS lists goal setting and planning as core skills [source: BPS 2019 §3.5.2]. Clarify what matters (roles, relationships, work, leisure), set specific, achievable goals, identify barriers and plan around them [source: BPS 2019 §3.4.2; synthesis on steps].
  • Example language (illustrative): "If pain had less say over your week, what would you be doing again?"
  • Watch for: goals phrased only as "pain down to 2/10". Translate them into activities [synthesis].

B8. Graded activity and exposure to feared movement

  • Purpose: reduce fear and avoidance of movement and activity.
  • Steps:
    1. BPS describes graded activity and exposure with goal setting, barrier management and structured practice to reduce fear and avoidance [source: BPS 2019 §3.4.2].
    2. Build a hierarchy of avoided activities with the client. Agree physical safety limits with the physiotherapist or doctor beforehand, get explicit consent, and give the client control over pace [synthesis; exposure safety].
    3. Practise, reflect on predictions versus outcomes, and step up gradually [synthesis].
  • Contraindications and safety: do not start exposure to activities the medical team has advised against, during an uninvestigated new pain, or while a medical review is pending [synthesis].
  • Example language (illustrative): "What do you predict will happen if you carry the shopping bag from the car? Let's test it in a small way you're willing to try."
  • Watch for: using the device as a hidden safety behaviour during exposure. Discuss openly whether to use it during practice, and leave the decision with the client [synthesis].

B9. Cognitive work on pain and device beliefs

  • Purpose: loosen unhelpful beliefs that drive distress and avoidance.
  • Steps: BPS describes identifying and changing unhelpful thoughts and beliefs, especially about pain [source: BPS 2019 §3.4.1]. Typical targets [synthesis]: "hurt means harm", catastrophising, "I can't manage without the machine", "if this doesn't work nothing will". Use guided discovery and behavioural experiments rather than argument.
  • Example language (illustrative): "What would it mean if the unit stopped helping? What else has got you through a bad day before?"
  • Watch for: invalidation. Beliefs about pain are revised, not dismissed [synthesis].

B10. Acceptance, mindfulness and psychological flexibility (ACT for pain)

  • Purpose: reduce the struggle with pain and support values-led action. NICE NG193 1.2.3 recommends considering ACT or CBT for pain, delivered by appropriately trained professionals [source: NICE NG193].
  • Steps: BPS lists acceptance, mindfulness and psychological flexibility methods [source: BPS 2019 §3.4.3]. Explore the costs of control strategies (including chasing relief), practise noticing pain sensations and thoughts without acting on them, and commit to values-based actions [synthesis on sequence].
  • Example language (illustrative): "You've tried a lot of ways to make the pain go away. What has the effort of fighting it cost you?"
  • Watch for: acceptance heard as "give up". Stress willingness and action [synthesis].

B11. Sleep

  • Purpose: address the pain–sleep cycle.
  • Steps: BPS describes group interventions that treat pain and insomnia together using CBT-I or ACT-based approaches [source: BPS 2019 §3.6]. Note that NHS advice is not to use TENS while sleeping [source: nhs.uk]. If the client uses it in bed, refer the question to the treating clinician [synthesis].
  • Example language (illustrative): "You mentioned dozing off with the unit on. That's worth checking with your physio. Meanwhile, let's look at your wind-down routine."
  • Watch for: daytime napping and long time in bed undermining sleep drive [synthesis].

B12. Flare-up and setback planning

  • Purpose: prepare for flare-ups without a return to rest and help-seeking cycles.
  • Steps: BPS includes setbacks and self-management of flare-ups [source: BPS 2019 §3.5.5, §3.8.4]. With the client, write a plan: early signs, what to do in the first hours and days (reduced but continued activity, relaxation or mindfulness, any strategies the treating team has endorsed), when to contact which professional, and how to step back up [synthesis]. If the client uses TENS, the plan simply records "as advised by my physio or pain team", with no settings [synthesis].
  • Example language (illustrative): "Let's write down what Future You does on day one of a flare, so you're not deciding in the middle of it."
  • Watch for: the plan becoming all passive strategies [synthesis].

B13. Conversations about medication and other treatments (routing to the prescriber)

  • Purpose: support adherence and ambivalence conversations without advising a change.
  • Steps: explore the client's views and worries about their medicines; help them prepare questions; route all change decisions to the prescriber. CUH advises speaking to the healthcare provider before changing medication [source: CUH 2024]. BPS describes medication review and rationalisation by the pain-team nurse and pharmacist [source: BPS 2019 §6.9–6.10].
  • Example language (illustrative): "It sounds like you're wondering whether you still need the tablets. That's a good question to take to your GP. Shall we note what you've noticed?"
  • Watch for: self-directed medication changes; inform the prescriber with consent if there is risk [synthesis].

B14. Monitoring and passing on side effects and warning signs

  • Purpose: close the loop with the treating team.
  • Steps: ask briefly about skin irritation, fainting or other unexpected effects, and about any change in health status relevant to listed contraindications (for example new pregnancy, new diagnosis of epilepsy, new implanted device) [source: nhs.uk; CUH 2024]. Encourage the client to report to the clinician; with consent, pass concerns on yourself [synthesis].
  • Example language (illustrative): "You mentioned a red patch under the pads. NHS advice is to stop and remove them if the skin is irritated. Can you let your physio know this week?"
  • Watch for: symptoms the client minimises to avoid losing the device [synthesis].

B15. Collaborative care with the physiotherapist and pain team

  • Purpose: one consistent plan.
  • Steps: BPS describes an interdisciplinary team with a shared cognitive behavioural framework, including an HCPC-registered physiotherapist and a psychologist (chartered, HCPC-registered or BABCP-registered CBT therapist) [source: BPS 2019 §6.4–6.7]. With consent: share formulation and goals; ask how the physiotherapist sees the device's role; agree common language on pacing and flare-ups; review progress together [synthesis on steps].
  • Example language (to a colleague, illustrative): "We're working on pacing and graded return to walking. How do you see TENS fitting in, so we give her the same message?"
  • Watch for: mixed messages ("rest when it hurts" versus "keep moving") [synthesis].

B16. Talking about consumer devices and marketing claims

  • Purpose: protect clients from wasted money, false hope and unsafe use.
  • Steps: ask where the device came from and what it claims; compare claims with official information (NHS, NICE, the device's cleared indication); remind them of the NHS advice to check with a professional first and to look for a CE or UKCA mark [source: nhs.uk; FDA K140168]; route specific questions to the physiotherapist or pharmacist [synthesis].
  • Example language (illustrative): "The advert says it fixes nerve pain. What does the leaflet in the box actually say it's for?"
  • Watch for: repeated purchases of new devices after each disappointment, which can point to a relief-seeking cycle worth exploring (B5) [synthesis].

B17. Pregnancy and labour

  • Purpose: respond appropriately when a pregnant client mentions TENS.
  • Steps: NHS information lists labour pain as a use but advises against use in pregnancy unless a doctor or midwife advises it [source: nhs.uk]. Refer questions to the midwife or obstetric team. Psychological work on birth anxiety continues alongside [synthesis]. NICE intrapartum guidance on TENS is not drawn on here [uncertain].
  • Example language (illustrative): "Your midwife is the right person to ask about TENS for labour. We can work on the worries about the birth here."
  • Watch for: birth anxiety narrowing onto the device or pain relief alone. Working if TENS questions go to the midwife and the anxiety work continues in sessions [synthesis].

B18. Crisis and safety planning

  • Purpose: address suicide risk, which standard practice treats as raised in persistent pain with hopelessness, insomnia or opioid access [synthesis].
  • Steps: routine risk enquiry; collaborative safety plan; lethal-means counselling about safe storage and reduced access to stockpiled medicines, without method detail; communicate with the GP or prescriber when risk is raised [synthesis].
  • Example language (illustrative): "When the pain is at its worst, do you ever have thoughts that life isn't worth living?"
  • Watch for: hopelessness when relief fails, insomnia, stockpiled medicines and withdrawal from others. Working if the client uses the plan and asks for help early [synthesis].

B19. Ending and support after treatment

  • Purpose: keep skills going.
  • Steps: review gains against goals; update the setback plan; plan booster sessions or peer support; agree routes back. BPS notes that long-term maintenance is hard and that returners should be reoriented to rehabilitation rather than repeated investigations and treatments [source: BPS 2019 §3.10.3–3.10.4].
  • Example language (illustrative): "What will tell you it's time to get back in touch, and what will you try first?"
  • Watch for: a return to rest-and-relief cycles or repeated device purchases after a setback. Working if the client uses the setback plan before seeking new treatments [synthesis].

5. Handling problems

The sources say little about psychotherapy-specific difficulties around TENS. Unless tagged otherwise, the guidance below is [synthesis].

  • "The machine is the only thing that works; don't take it away." Make clear you are not taking anything away and are not the person who decides about the device. Explore what it enables and build further strategies alongside it (B5). Avoid power struggles.
  • Feeling dismissed by "NICE doesn't recommend it". Separate the guideline from the person: NG193 1.2.6 is about what services should offer for chronic primary pain, not a judgement on the client's experience [source: NICE NG193]. Validate the relief they feel and redirect to goals.
  • Relief fading, escalating use, buying more devices. Treat it as information about a relief-seeking cycle (B5, B16). Encourage a review with the physiotherapist or pain team, who can also check technique; Johnson and Jones note that declining response needs troubleshooting by the user with professional support [source: Johnson & Jones 2017].
  • Stuck: "I'll start living once the pain is fixed." Use creative hopelessness and values work (B10), or a cost–benefit review of waiting. Set one small values-based action this week.
  • Non-adherence to pacing or graded activity. Check whether goals were too large, set by pain level, or not the client's own. Shrink the step, problem-solve barriers (B6–B8), and check whether boom-and-bust on "good TENS days" is part of the pattern.
  • Overwhelm during exposure or pain education. Slow down, return to a lower step, use grounding or brief mindfulness, and re-check consent. Stop and refer if new or unexplained pain or symptoms appear.
  • Rupture: "You think it's all in my head." Acknowledge the rupture directly and own any part you played. Restate that pain is real and involves body and nervous system, and that psychological work targets the suffering and disability around it, not the pain's legitimacy (B3).
  • Client asks you for settings, pad positions or which device to buy. Decline kindly, explain your role, and help them write the question for the physiotherapist, pharmacist or pain team (B2). Do not give opinions on settings, even informally.
  • Possible contraindication disclosed (pacemaker, epilepsy, pregnancy, skin problems, implanted device). Advise the client to stop and check with their clinician before further use, in line with NHS advice, and document it [source: nhs.uk; CUH 2024].
  • Use in risky situations (driving, sleeping, bathing, operating machinery). NHS and CUH advise against these [source: nhs.uk; CUH 2024]. Share the information, encourage a discussion with the clinician, and explore what makes it hard to keep to (for example, night-time pain driving sleep use; see B11).
  • Medication changes made because of TENS. Explore without judgement; encourage the client to tell the prescriber promptly; pass on risk concerns with consent (B13).
  • Conflicting messages from different professionals or online sources. Ask for a team conversation (B15); help the client list the conflicting points and take them to one lead clinician.
  • Litigation, benefits or work disputes. BPS states that litigation is no reason for exclusion [source: BPS 2019 §1.9]. Keep goals functional; be careful and factual in any reports.
  • Hopelessness or suicidal thoughts as relief fails. Move to risk assessment and safety planning (B18), with GP or prescriber contact as indicated.
  • Returners after a programme. Revisit the setback plan and skills and reorient to rehabilitation rather than repeated investigations and treatments [source: BPS 2019 §3.10.4].
