About us

Pain patients are the focus of attention at the IISZ. Many years of experience from academic research and clinical practice flow directly into the treatment of our patients.


Mission statement

Our patients are the focus of our efforts. Diagnostic and therapeutic measures are always coordinated individually. A personalized treatment strategy is determined based on partnership.

The IISZ provides scientifically based, goal-oriented pain medicine treatment. The team at the IISZ is constantly undergoing further training in order to guarantee well-grounded, up-to-date treatments at all times.

There are often complex causes for pain. That is why a careful diagnosis is extremely important. In addition to a precise anamnesis, a physical examination, the study of available reports and findings (X-ray, CT, MRI, ENMG, laboratory,...), the interventional assessment is of central importance. In the case of nerve pain, Quantitative Sensory Testing (QST) enables the creation of an individual sensitivity profile. QST provides important information about the nerve fibers in the skin, as well as about the processing of the pain sensation in the spinal cord and brain. Taking the diagnostic findings into account, a detailed treatment plan is drawn up and implemented.

In general terms, the term "intervention" describes a decisive intervention against a disease process or against a pain problem. In pain medicine practice, the term "intervention" means a small, minimally invasive procedure (injection, syringe). All interventions at the IISZ are performed precisely under X-ray and/or ultrasound control. Patients are only minimally burdened by interventions.

In pain therapy, the use of medication is often unavoidable. By knowing the cause of the pain and the individual circumstances of a patient, the potential effectiveness of a medication can be assessed. In cases of doubt or in order to better predict or check the effectiveness of certain pain medication, intravenous drug tests (opiates, Na+ channel blockers, NMDA-R blockers) are carried out at the IISZ. The pain-modulating effect of the test medication is determined during the infusion. Based on the test result, a conclusion can be drawn about the potential effectiveness of certain pain medications.

The treatment of chronic pain is often complex. If necessary, the IISZ can rely on a broad network of proven pain specialists from various disciplines (family medicine, neurology, rheumatology, acupuncture, chiropractic, complementary medicine, physiotherapy, psychotherapy, occupational therapy). The IISZ relies heavily on close multidisciplinary cooperation and has a regular exchange with the colleagues involved.

Coordinated care is particularly important as the treatment of chronic pain often requires a multidisciplinary approach. We attach great importance to ensuring that individual diagnostic and therapeutic measures are well coordinated. Through low-threshold exchange with general practitioners and other specialists involved, targeted treatment management is achieved.
