The DNHS® technique relies on dry needle punctures, using needles similar to those used in acupuncture (filiform and solid, non bevelled needles), without introducing any substance into the body. The target structure for the DNHS® technique is the myofascial trigger point, specifically the dysfunctional endplate responsible for the contraction of the sarcomeres.
This technique has been applied in different health clinics since 2007 as part of a range of physiotherapy services offered to patients with hypertonia, spasticity or movement disorders of a central origin.
The recommended treatment frequency is one session per week at most, although more frequent sessions may be possible as long as the same muscles or muscle areas are not repeatedly punctured. This frequency must be observed, as the neuromuscular injury caused by the needle satisfies all prognostic factors for positive feedback mediated by satellite cells (see articles), and is estimated to occur within 7 to 10 days.
Dry echo-guided puncture for improved safety
Sometimes due to the patient’s own risks (anticoagulants) or the area, it is recommended to perform dry puncture in an echo-guided way.
