Dry Needling for Hypertonia and Spasticity (DNHS®) is a dry needling technique designed with specific application criteria for patients with damage to the central nervous system. The goal of this technique is to improve centrally originated hypertonia, spasticity, and disorders of movement and function.

Dry needling techniques have been used by physiotherapists for years in Spain and other countries for the treatment of myofascial pain. Several studies have demonstrated that dry needling techniques are equally as effective for the treatment of myofascial pain as infiltration of substances such as botulinum toxin, with the advantage of having no side effects.

The DNHS® technique was registered in 2007 by researcher Pablo Herrero as a variation on the traditional dry needling techniques, with specific criteria applicable to patients with central nervous system injury. The first of the publications on the DNHS® technique was issued in 2007, and showed that the technique was effective in reducing hypertonia and spasticity in patients with central nervous system injury. Unlike the treatment of myofascial pain, the effectiveness of the DNHS® technique has not yet been compared with botulinum toxin infiltration. The research is currently focused on comparing the effectiveness of the technique with other physiotherapy treatments or control groups.
