Electroencephalographic Changes After Application of Dry Needling [DNHS^© Technique] in Two Patients With Chronic Stroke

Abstract

Background: Dry needling [DNHS© technique] is a promising treatment modality for patients with spasticity. However, little is known regarding the indirect effects of dry needling on regional brain activity. This study aimed to describe the electroencephalographic changes found after the application of DNHS© in two patients with stroke.Findings: Two patients with chronic stroke and spasticity received a single session of dry needling in spastic muscles selected after clinical evaluation. An improvement in the regional brain activity was observed after the application of DNHS© based on the measurement of quantitative electroencephalographic activity and electroencephalographic cordance.Conclusions: This study shows that the DNHS© technique, which is based on a peripheral application, has a positive effect on regional brain activity.
