Trigger points develop through overload, poor posture or stress. Within an affected muscle strand, a tiny bundle of fibres stays permanently contracted and is no longer properly supplied with blood. The hallmark is referred pain: a trigger point in the shoulder blade can cause headaches, one in the buttock can send discomfort down the leg. This is what makes trigger points hard to pinpoint – the site of pain is not always its source.
During treatment the therapist feels for the hardened spot and applies sustained, targeted pressure with a thumb, knuckle or tool for a few seconds until the muscle releases. This is complemented by stretching, fascia techniques or – in the specialised form – dry needling. The pressure can be briefly intense (a 'good hurt') but should always stay bearable. A session lasts 20 to 45 minutes depending on the area.
Trigger point therapy is used for tension headaches, neck and back pain, tennis elbow, shoulder complaints and hip or knee pain. After treatment the area may feel slightly sore for a day or two – this is normal. It is important to address the triggering factors (such as the office chair, one-sided strain or stress), otherwise the points return.
As part of physiotherapy, trigger point treatment is covered by basic insurance with a medical prescription. As medical massage with an EMR-recognised therapist it is often covered by supplementary insurance. Self-payers can expect roughly CHF 90 to 130 per hour (no guarantee).
