{"title":"Les ondes de choc à Dudelange","content":"**Extracorporeal shock waves deliver brief acoustic pulses to a tendon, a fascia or a calcification. At the Pôle Equilibre & Santé practice, Bloc A, 48 Rue de la Libération in Dudelange, we use a radial Swiss DolorClast and a PiezoClast / DolorClast Focused. They complement a loading programme: they never replace it.**\n\n## Radial or focused: two depths, one goal\n\nThis is not electricity. A gel couples the head to the skin; the pulse is mechanical. The radial **Swiss DolorClast** (ballistic) spreads energy over a wider area, useful to about 4–5 cm — plantar fascia, superficial tendons, certain myofascial points. The **PiezoClast** (focused / piezoelectric) concentrates energy deeper, notably on a shoulder calcification or an insertion that is hard to reach.\n\nThe choice depends on depth, useful imaging, your tolerance and the goal of the day — not on a race for maximal intensity.\n\n## What we treat, what we do not promise\n\nThe best-documented situations remain **plantar fasciitis** (first-step pain) and certain **shoulder calcifications** when clinical findings and imaging agree. Patellar, epicondyle, cuff: possible case by case, always as an adjunct to progressive loading. A tendinopathy that is still very hot is generally not the right timing. Achilles is not presented here as a routine indication.\n\nShock waves do not “break” a tendon. They can modulate pain and influence the local metabolism of a chronic tissue. The foundation remains loading work, linked to [sports physiotherapy](/dudelange/competence/kinesitherapie-du-sport) or [orthopaedic rehabilitation](/dudelange/competence/reeducation-orthopedique).\n\n## Before the first series of pulses\n\nClean skin, clothing that uncovers the area, prescription and imaging reports. Mention pregnancy, local infection, unconsolidated fracture, tumour on the site, severe coagulation disorder, a pacemaker if the area is nearby, or unexplored acute pain. A light meal is enough. Avoid a thick cream.\n\nCommon contraindications: pregnancy over the area, infection or open wound, severely altered coagulation, local malignant tumour, open epiphysis in a child — the assessment rules them out.\n\n## During the session, then the following days\n\nGel, head applied, intensity raised with you. Sensation of dry knocks, sometimes unpleasant but controlled: we lower or move if it is too much. Often **a few minutes** per site, within a session of about thirty minutes that mainly contains exercises and loading advice. Three to five spaced sessions are common; the rhythm is decided according to the response.\n\nAfterwards: redness or local sensitivity for 24–48 h is possible. Brief ice if needed. Driving is generally possible. A match the same evening is not reasonable. Desk work: according to pain. Sport and physical jobs: the criteria remain strength, control and medical advice — not the number of shocks received.\n\nResults: relief may appear within a few sessions for certain selected fasciitis or calcifications. A lasting change is judged over weeks, with the loading programme. If nothing moves after a well-conducted trial, we stop.\n\n## Frequently asked questions\n\n\nHow should I prepare and what should I wear?\n\nAccessible area, clean skin, prescription and useful imaging. Mention pregnancy, infection, coagulation disorder or new acute pain.\n\n\n\n\nHow long does the application last?\n\nA few minutes per site, within an overall session of about thirty minutes. The rest of the time goes to exercises and the loading plan.\n\n\n\n\nIs it painful?\n\nDry knocks, dosed with you. Tolerable discomfort: we continue. Sharp or intolerable pain: we lower immediately.\n\n\n\n\nHow many sessions are needed?\n\nOften three to five, spaced out. The number depends on the response, not on a fixed package. Without clear benefit, we interrupt.\n\n\n\n\nCan I drive, and when can I resume sport?\n\nDriving generally possible. Sport: after assessment of load and pain, not on the evening of an intense session.\n\n\n\n\nWhat are the contraindications, and is it reimbursed?\n\nPregnancy over the area, infection, unconsolidated fracture, local tumour, severely altered coagulation: the assessment rules them out. On medical prescription, the [CNS](https://cns.public.lu/) covers the session according to the usual rules. The practice handles the paperwork. See [the physiotherapy consultation](/dudelange/kinesitherapie/consultation-kine).\n\n\n\n\nHow can I book an appointment?\n\nBy phone on [+352 26 65 15 33](tel:+35226651533).
