Deep transverse friction (Cyriax)

1. Introduction

Version followed: deep transverse friction (DTF, also called transverse friction massage or cross-friction) as described in James Cyriax's orthopaedic medicine (Textbook of Orthopaedic Medicine, vol. II, Treatment by Manipulation, Massage and Injection) and as reported by physiotherapy and chiropractic sources that follow it; the 2005 Western States Chiropractic College clinic procedure is used for practical detail, and the Cochrane review (Loew et al., 2014) for evidence status. [source: Coldham 1976; Winter 1972; WSCC 2005; Loew et al. 2014]

DTF is a hands-on technique delivered by physiotherapists, physical therapists, chiropractors and some manual and massage therapists, not by psychotherapists. The clinician applies a deep, short, to-and-fro movement across the fibres of a precisely located lesion in a tendon, tendon sheath, ligament or muscle. In the Cyriax account, friction restores mobility: it frees adhesions between muscle fibres so the muscle can broaden on contraction, moves a ligament over bone as it would normally move, and smooths a roughened tendon sheath or breaks up scar at a tendon's bony insertion. [source: Coldham 1976] Clinic procedures also describe increased local circulation, reduced collagen cross-linking and local analgesia that builds during treatment; these mechanisms are presented as theory. [source: WSCC 2005]

Evidence status: the Cochrane review (2 small trials, 57 participants; lateral elbow and lateral knee/iliotibial band) found insufficient evidence to determine effects on pain, grip strength or function, with very low-quality evidence and no reporting of adverse events. [source: Loew et al. 2014] A systematic review of nine studies concluded that the effect of friction on its own has not been established; some benefit was reported only when combined with other treatments (Mill's manipulation at the elbow, joint mobilisation at the shoulder). [source: Joseph et al. 2012] A 2026 narrative review of 22 studies concluded it may give short-term benefit as an adjunct to exercise-based rehabilitation for some tendinopathies but cannot be recommended as stand-alone treatment. [source: Galanis et al. 2026] Physiotherapy authors have argued it should not be a first-line treatment for chronic pain. [source: Pitsillides & Stasinopoulos 2019] It is not a treatment for any systemic disease.

This guide is written for the psychotherapist: what the method involves, who delivers it, its safety screening, and the psychotherapist's own role around it.

2. Framework

DTF is one treatment within Cyriax's orthopaedic medicine, which always begins with diagnosis. The phases below describe what the treating clinician does; the psychotherapist's parallel tasks are in section 4B. [source: Winter 1972; Coldham 1976; WSCC 2005]

Phase 1: Diagnosis. History, inspection, functional examination by selective tension (resisted and passive movements that load specific structures), palpation, sometimes diagnostic local anaesthesia (by a doctor). Goal: identify the exact tissue at fault. Cyriax's school insists that the technique follows an accurate diagnosis; reviewers warned physiotherapists not to use "apparently simple techniques such as transverse frictions" without it. [source: Winter 1972] Moving on: a specific structure and site is identified.
Phase 2: Localisation. The site is found on the structure identified, not simply where it hurts: tenderness alone is not a reason to massage there. [source: Coldham 1976; WSCC 2005]
Phase 3: Friction sessions. Positioning, friction across the fibres, reassessment against the functional test. Sessions are spaced rather than daily; session length and interval are set by the clinician according to the school's texts and vary between authors. [source: WSCC 2005; Pitsillides & Stasinopoulos 2019]
Phase 4: Movement after friction. Passive or active movement, and in some lesions a Cyriax manipulation (for example Mill's manipulation for lateral elbow tendinopathy). [source: Coldham 1976; Joseph et al. 2012]
Endpoints and stopping. The clinic procedure uses the functional test as endpoint: a resisted test or joint-play test that is pain-free. It states that no improvement after a few early treatments means friction is unlikely to help. [source: WSCC 2005]
Format. Individual, hands-on, usually within a wider physiotherapy or rehabilitation plan including exercise. [source: Galanis et al. 2026]

3. Guiding principles

Principles of the method as its sources give them, followed by principles for the psychotherapist.

Diagnosis first. Treatment is only as good as the diagnosis of the exact tissue. Practical meaning: ask the client whether a clinician has examined and named the structure being treated. [source: Winter 1972; Coldham 1976]
The right spot. Friction is applied to the lesion, not to wherever pain is felt. Practical meaning: the client may be treated away from where they feel pain; this is expected. [source: Coldham 1976; WSCC 2005]
Across the fibres. The movement runs transversely; friction along the fibres may increase inflammation. Practical meaning: the method is defined by direction, not by general rubbing. [source: Coldham 1976; WSCC 2005]
Finger and skin move as one. No oil; the clinician's finger and the client's skin move together over the deeper tissue, otherwise only the skin is rubbed and blisters can form. Practical meaning: the client should not expect a gliding massage. [source: Coldham 1976; WSCC 2005]
Sufficient sweep and depth. Friction must cover the lesion and reach it; brief deep work is preferred to long gentle rubbing. [source: Coldham 1976]
Tissue position. Muscles are treated relaxed; sheathed tendons are kept taut; position is changed to reach deep structures. Practical meaning: clients may be placed in unusual positions, which matters for clients with trauma histories. [source: Coldham 1976; Chaves et al. 2017]
Tolerable discomfort, analgesia, then depth. Treatment usually starts uncomfortable; pressure stays within tolerance and increases only as local numbness develops; the procedure says to stop if symptoms worsen or numbness does not develop. Practical meaning: discomfort is part of the method, so consent and a stop signal are essential. [source: WSCC 2005; Chaves et al. 2017]
Adjunct, not stand-alone. Current reviews place it alongside active, exercise-based rehabilitation. [source: Galanis et al. 2026; Joseph et al. 2012]
Psychotherapist: stay within competence and refer. The psychotherapist does not deliver friction; codes require practitioners to offer only what they are trained for and to refer when appropriate. [source: UKCP 2019, clauses 23–24]
Psychotherapist: touch is consented, explained, stoppable, never sexual. The client consents before and during touch and can stop at any moment; the purpose of each touch is explained in advance; chaperones are offered for close examinations; no sexual contact ever. [source: CSP 2023; UKCP 2019, clause 4]
Psychotherapist: the body experience belongs in therapy. Pain, positioning and being handled can evoke memories and feelings; these are material for psychotherapy, explored verbally. [synthesis]

4. Intervention inventory

Part A describes what the treating clinician does, so the psychotherapist can explain it accurately and prepare the client; these are not instructions for psychotherapists to perform. Part B is the psychotherapist's own work. Example language throughout is illustrative.

Who delivers it and how they are regulated

In the UK, "physiotherapist" and "physical therapist" are protected titles; practitioners must be registered with the Health and Care Professions Council (HCPC), which investigates complaints against its Standards of Proficiency and Standards of Conduct, Performance and Ethics; the professional body is the Chartered Society of Physiotherapy (CSP). [source: UK Regulated Professions Register; CSP 2023]
Chiropractors also use transverse friction (the procedure used here is a chiropractic college clinic protocol). [source: WSCC 2005] Their regulators (e.g. the General Chiropractic Council in the UK, state boards in the US) [uncertain: not verified].
Massage therapists may use cross-fibre friction; regulation varies (US state massage boards, MBLEx exam via FSMTB, NCBTMB board certification; UK CNHC voluntary register) [uncertain: not verified]. In Canada, five provinces regulate massage therapy through a college that licenses therapists, sets standards and publicly reports discipline (Ontario, British Columbia, New Brunswick, Newfoundland and Labrador, Prince Edward Island); elsewhere the profession is not government-regulated and therapists join associations [source: HHR-RHS Canada; CBC 2021]. In Australia, there is no national registration; massage therapists fall under the National Code of Conduct for health care workers not registered under the national scheme, applied by state health complaints entities (in WA the implementing bill was still before parliament in September 2022), and AMT members can be reported to AMT's Discipline Committee [source: HaDSCO WA 2022; AMT]. The Cyriax method as taught by its schools is aimed at doctors and physiotherapists. [source: IAOM-US]
Training bodies: the International Academy of Orthopedic Medicine (IAOM), founded in 1978 by James Cyriax and physical therapist Dos Winkel, offers continuing education mainly for physicians and physical therapists. [source: IAOM-US] ETGOM, founded by Bob De Coninck, runs modular Cyriax courses with a diploma pathway in many countries. [source: Bwizer 2012] Cyriax himself taught physiotherapists in his clinics at St Andrew's Hospital, London. [source: Winter 1972] Other national societies of orthopaedic medicine exist [uncertain: not verified].

A1. Diagnostic examination by selective tension (clinician)

Purpose / when used: to identify the exact tissue at fault before any friction. [source: Winter 1972; Coldham 1976]
Steps (as described): history; inspection; functional examination (resisted movements for muscles and tendons, passive movements and joint play for ligaments and capsule); palpation along the structure identified; for some structures, finding tenderness with the tendon stretched; sometimes diagnostic local anaesthesia by a doctor. [source: WSCC 2005; Bwizer 2012; Winter 1972]
Example language (illustrative, psychotherapist to client): "Before any friction, the physio will test which movements hurt, to find the exact tissue involved. You can ask them what they found and why they chose that spot."
Watch for: treatment started without an examination; a client confused about why a painless area is treated (expected in this method); unexplained joint swelling, which the source says must be investigated before treatment. [source: Coldham 1976]

A2. Deep transverse friction (clinician)

Purpose / when used: chronic or subacute lesions of tendons, tendon sheaths, ligaments and muscle bellies or junctions, e.g. elbow tendons, Achilles, patellar tendon, knee collateral and coronary ligaments, rotator cuff tendons, ankle ligaments, hamstrings; also used on scar tissue. [source: WSCC 2005; Coldham 1976] Lighter transverse massage is used in acute injury and deeper friction in chronic injury; some authors propose separate names for the two. [source: Pitsillides & Stasinopoulos 2019; WSCC 2005]
Steps (as described, in general terms): the client is positioned so a muscle is relaxed or a sheathed tendon is taut; the clinician places a reinforced finger or thumb on the lesion, with no lotion; finger and skin move together across the fibres with enough sweep to cover the lesion; pressure starts at a tolerable level and increases only as local numbness develops; the clinician reassesses with the functional test during and after the session. Session length, interval and number are set by the clinician and differ between authors. [source: Coldham 1976; WSCC 2005; Chaves et al. 2017]
Example language (illustrative, psychotherapist preparing client): "Friction usually feels sore at first and then often numbs. You decide what is tolerable; you can say 'stop' or raise a hand at any time, and they should stop straight away."
Watch for: pain that increases rather than eases, or no numbness developing, which the procedure treats as a reason to stop; blisters or skin abrasion (poor technique or long fingernails); soreness or flare-up after sessions. [source: WSCC 2005; Coldham 1976] Psychologically: freezing, dissociation or silent endurance of pain the client did not want. [synthesis]

A3. Movement after friction and Cyriax manipulation (clinician)

Purpose / when used: to use and maintain the mobility gained; at the lateral elbow, Cyriax combined friction with Mill's manipulation, and some evidence of benefit comes from that combination. [source: Coldham 1976; Joseph et al. 2012] Some authors reject Mill's manipulation for lack of evidence. [source: Pitsillides & Stasinopoulos 2019]
Steps (as described): passive movement early, stronger movement later in ligament lesions; active movement within a pain-free range; in some lesions a quick manipulative thrust by a trained clinician; clinic procedures may add ice and gentle stretching. [source: Coldham 1976; WSCC 2005]
Example language (illustrative): "If they plan a manipulation, it is fine to ask them to describe it first and to agree a signal for stopping before they begin."
Watch for: a sudden, forceful movement the client did not expect, which can feel like a violation for clients with trauma histories; ask whether the client was told in advance. [synthesis]

A4. Contraindication and safety screening (clinician)

Purpose: to exclude tissues and people for whom friction may harm. [source: WSCC 2005; Coldham 1976]
Contraindications and cautions given by the sources: acutely inflamed tissue, including acute bursitis from trauma, infection or inflammatory arthritis; haematomas; calcifications; directly over peripheral nerves; myofascial trigger points (one author); impaired vascular response, including long-term or high-dose steroid use and peripheral vascular disease; caution with aspirin or anticoagulants; caution shortly after a steroid injection; chronic bursitis may flare at first; capsular thickening suggesting rheumatoid-type arthritis contraindicates active physiotherapy; unexplained joint effusion must be diagnosed first; cruciate ligament sprain is not a friction indication. [source: WSCC 2005; Coldham 1976]
Further general massage cautions (deep vein thrombosis, bleeding disorders, fragile skin, osteoporosis, cancer, pregnancy) apply to deep soft-tissue work generally; screening and medical clearance rest with the treating clinician and the client's doctor. [uncertain: not verified for DTF specifically]
Example language (illustrative): "Please tell the physio about any blood thinners, recent injections, steroid use, circulation problems or swelling. It is their job to decide whether friction is safe."
Watch for: a client who withholds medical information from the clinician out of shame or wish to please; the psychotherapist encourages disclosure and does not make the medical decision. [synthesis]

B1. Deciding whether to suggest it

Purpose / when to use: when a client in psychotherapy has a localised tendon, ligament or muscle problem (e.g. tennis elbow) and asks about hands-on treatment, or is already receiving it. The psychotherapist does not diagnose or prescribe; the suggestion is to see a regulated clinician who will examine and decide. [synthesis; source: UKCP 2019, clauses 23–24]
Steps: (1) ask whether the problem has been medically assessed; (2) explain in neutral terms that DTF is one option within physiotherapy, usually alongside exercise, with limited and uncertain research support; (3) suggest the GP or a registered physiotherapist; (4) do not suggest it for widespread pain, unexplained swelling, or where the client's distress about touch outweighs any expected benefit. [synthesis; source: Loew et al. 2014; Galanis et al. 2026]
Example language (illustrative): "A physiotherapist can examine the elbow and tell you what they recommend. Friction massage is one thing they might use, usually together with exercises. The research on it is mixed, so it is worth asking them what they expect it to do."
Watch for: the client hoping a hands-on treatment will fix emotional pain; a client who feels unable to refuse a practitioner; overvalued expectations. [synthesis]

B2. Referral and collaboration

Purpose: coordinated, consented care between psychotherapist and treating clinician. [synthesis]
Steps: (1) obtain written consent for any contact and agree what is shared (e.g. trauma-related needs around touch, not the content of therapy); (2) with consent, tell the clinician about adaptations the client wants (stop signal, chaperone, clothing, positions to avoid); (3) agree that adverse physical effects are reported to the clinician and the GP; (4) record the referral and consent. [synthesis; source: UKCP 2019, clause 14 on referral information]
Example language (illustrative): "Would it help if, with your permission, I let the physio know that you'd like each step explained before it happens? I would only share what you agree to."
Watch for: sharing more than agreed; the client feeling discussed behind their back; dual-role drift if the psychotherapist starts giving physical advice. [synthesis]

B3. Preparing a client with a trauma history for touch and treatment pain

Purpose: to make consented, stoppable touch possible for clients for whom being held in position, touched firmly or hurt may evoke past abuse or medical trauma. DTF is deliberately uncomfortable at first, which makes preparation especially relevant. [synthesis; source: WSCC 2005 on initial discomfort]
Steps: (1) explore what the client knows of the treatment and what feels difficult (being positioned, undressing the area, pain, a clinician's gender); (2) build a consent plan: the right to ask for an explanation of each touch beforehand, to say no to any part, to stop at any moment, and to bring someone or request a chaperone; physiotherapy guidance says chaperones should be provided on request where the service can, and that the purpose of touching must be explained in advance; (3) agree a clear stop signal and practise saying it aloud in session; (4) plan grounding the client can use on the treatment couch (feet, breath at their own pace, looking around the room) without giving any breathing prescription; (5) plan what to do if they freeze. [source: CSP 2023; synthesis for steps 1, 3–5]
Example language (illustrative): "Let's practise how you'd say 'please stop' to the physio. Try it out loud now. What would make it easier to say on the day?"
Watch for: the client agreeing to everything to be a good patient; freezing or going quiet as a sign that consent may have lapsed; shame about needing adaptations. [synthesis]

B4. Integrating the body experience in psychotherapy

Purpose: to use the experience of treatment (pain, relief, being handled, setting limits) as therapeutic material, verbally, without touch from the psychotherapist. [synthesis]
Steps: (1) invite a description of the session in the client's words; (2) separate the physical facts (what was done, what hurt, what helped) from the meanings and memories that arose; (3) notice and reinforce any boundary the client set; (4) link to current therapeutic themes (trust, control, tolerating discomfort, asking for help); (5) check whether to continue, adapt or stop treatment, and who will tell the clinician. [synthesis]
Example language (illustrative): "When you said the pressure was too much and they eased off, what was that like for you?"
Watch for: intrusive memories or flashbacks after sessions; persistent fear of returning; idealisation of the clinician; the psychotherapist must not offer touch to "complete" the experience. A sexual-and-relationship-therapy body states that talking therapy does not involve physical touch. [source: COSRT 2024; synthesis]

B5. Recognising and passing on adverse effects

Purpose: to ensure physical adverse effects reach the clinician and doctor quickly. [synthesis]
Steps: (1) ask after each treatment how the area feels; (2) know the documented effects: soreness or flare-up, blisters or skin abrasion, and failure of symptoms to improve; (3) encourage the client to report these to the clinician; (4) for marked swelling, bruising, numbness or tingling, increasing pain, or warmth and redness, advise prompt contact with the clinician or GP; (5) record what was advised. [source: WSCC 2005 for step 2; synthesis for steps 1, 3–5]
Example language (illustrative): "That bruising is worth showing the physio or your GP before the next session. Shall we think about how you'll tell them?"
Watch for: clients minimising harm to avoid seeming difficult; psychological after-effects being dismissed as "part of the treatment". [synthesis]

B6. Recognising boundary violations and supporting reporting

Purpose: to protect clients from unprofessional or sexual conduct by practitioners. [source: CSP 2023; UKCP 2019, clause 4]
Steps: (1) know what professional practice looks like: the purpose of touch explained in advance, privacy for undressing, covering with towels, factual and clinically relevant questions, chaperones for intimate or close examinations, records of chaperone offers; (2) take seriously any report of touch outside the treated area, unexplained undressing, sexualised remarks, or touch near intimate areas; DTF of the limbs and trunk should never involve genital touch; (3) support the client to make a complaint to the regulator (HCPC for UK physiotherapists) or the clinic, and follow your own safeguarding duties; (4) document carefully. [source: CSP 2023; UK Regulated Professions Register; synthesis for steps 2–4] For other professions and countries, the relevant regulator is listed on its own register [uncertain: not verified].
Example language (illustrative): "What you describe isn't part of that treatment. You have the right to complain, and I can help you think through how to do that."
Watch for: self-blame; fear of not being believed; the practitioner having presented unusual touch as part of the technique. [synthesis]

5. Handling problems

The sources address technique problems (pain, no analgesia, no progress); the psychological problems below are this guide's synthesis unless cited.

Treatment pain is too much or does not ease. The clinic procedure says to stop if symptoms worsen or numbness does not develop, and to keep pressure within tolerance. Response: help the client tell the clinician, and remind them they may stop at any time. [source: WSCC 2005; synthesis]
No improvement. The clinic procedure states that lack of early improvement makes benefit unlikely; reviews find little support for friction on its own. Response: encourage the client to ask the clinician about stopping or changing approach, e.g. towards exercise-based rehabilitation, rather than persisting. [source: WSCC 2005; Joseph et al. 2012; Galanis et al. 2026]
Freezing, dissociation or flashback during treatment. Response: review the consent plan and stop signal (B3); consider a chaperone or companion, a different clinician, or pausing hands-on treatment; process the episode in therapy (B4). [synthesis]
Client cannot refuse or speak up (compliance, fawning). Response: rehearse refusal in session; frame stopping as the client's right and the clinician's expectation; explore what makes refusal feel dangerous. [synthesis]
Avoidance or non-attendance at physiotherapy. Response: explore whether fear of pain or touch is driving it; respect a decision not to have hands-on treatment, and remind the client that active, exercise-based options exist and are the focus of current recommendations. [source: Galanis et al. 2026; synthesis]
Over-reliance on passive treatment. Response: explore the wish to be fixed by someone else; support engagement with the active parts of rehabilitation the clinician recommends, without prescribing them. [synthesis]
Rupture with the psychotherapist (e.g. the client feels the psychotherapist pushed them towards a painful treatment or doubted its value). Response: acknowledge, explain that the decision is theirs and the clinician's, and repair. [synthesis]
Client asks the psychotherapist to do friction or to touch. Response: decline; it is outside the psychotherapist's competence and talking therapy does not involve touch; refer back to the treating clinician. [source: UKCP 2019, clauses 23–24; COSRT 2024]
Medical red flags (unexplained swelling, signs of infection, calf pain or swelling, worsening numbness, new symptoms after a steroid injection, anticoagulant use not disclosed). Response: advise contact with the clinician or GP before the next session; the medical decision is not the psychotherapist's. [source: WSCC 2005; Coldham 1976; synthesis]
Suspected boundary violation by a practitioner. Response: follow B6; support a complaint to the regulator; consider safeguarding duties. [source: CSP 2023; synthesis]
