What it is

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,…

Format

• 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.
• Format. Individual, hands-on, usually within a wider physiotherapy or rehabilitation plan including exercise.

Evidence status, as the guide reports it

• 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…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Does it use a device, heat, cold, water or a physical procedure? Has a medical professional checked that it is safe for you?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• self-blame; fear of not being believed; the practitioner having presented unusual touch as part of the technique.
• clients minimising harm to avoid seeming difficult; psychological after-effects being dismissed as "part of the treatment".
• the client hoping a hands-on treatment will fix emotional pain; a client who feels unable to refuse a practitioner; overvalued expectations.
• sharing more than agreed; the client feeling discussed behind their back; dual-role drift if the psychotherapist starts giving physical advice.
• 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.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
