therapeutic currents - clinical research
The Zenni Method builds on decades of scientific research into galvanic and diadynamic currents, applying their clinically proven effects to promote healing and restore balance in the body.
Studies have shown that both galvanic and diadynamic currents offer gentle yet powerful therapeutic effects across a broad range of chronic health conditions.
Galvanic current has been found to ease anxiety, improve circulation in conditions such as Raynaud’s phenomenon, support neurological recovery after stroke, and show promising effects in managing motor symptoms in Parkinson’s disease and cognitive decline in dementia. Diadynamic currents have demonstrated effectiveness in relieving pain, reducing inflammation, and improving mobility in musculoskeletal and localised pain conditions, often outperforming other electro-therapies.
To explore the scientific evidence behind galvanic and diadynamic currents, continue reading below for key scientific findings.

Galvanic Current for Raynaud's Phenomenon
Clinical evidence indicates that combining galvanic current therapy with standard care offers greater relief from the symptoms and disability of Raynaud's phenomenon than conventional treatment alone.
Galvanic Vestibular Stimulation and Anxiety
A single session of galvanic vestibular stimulation (GVS) was found to significantly lower anxiety levels in young adults, suggesting a promising role for GVS in emotional regulation.
tDCS in Stroke Recovery
Transcranial direct current stimulation (tDCS) is emerging as a valuable approach in strokere habilitation, with research supporting its ability to alleviate a range of post-stroke symptoms.
Galvanic Therapy Across Wide Range of Conditions
Galvanic therapy has been suggested as a supportive treatment for numerous conditions, including menstrual pain, respiratory and digestive issues, inflammation, neuralgia, migraines, and various reproductive and urogenital disorders - highlighting its broad therapeutic potential.
Diadynamic Currents for Musculoskeletal Issues
Diadynamic current therapy has been shown to effectively reduce pain and improve function in a wide range of musculoskeletal conditions.
Heel Pain Relief with Diadynamic Current
Research supports the use of diadynamic currentas an effective treatment for heel pain, leading to meaningful pain relief andimproved mobility.
Galvanic Vestibular Stimulation in Parkinson's Disease
Emerging research suggests that Galvanic Vestibular Stimulation (GVS) may help improve motor symptoms in individuals living with Parkinson’s disease, highlighting its potential as a supportive neurotherapeutic approach.
Non-Invasive Brain Stimulation for Cerebral Palsy
Non-invasive brain stimulation (NIBS) is showing promise as a complementary therapy toenhance upper-limb rehabilitation in children and young adults with unilateralcerebral palsy.
tDCS for ADHD in Children
Transcranial direct current stimulation (tDCS) has been linked to measurable improvements inattention and behavioural control in children with ADHD.
Cognitive Beneftis of tDCS in Alzheimer's Disease
In patients with Alzheimer’s disease, tDCS has shown potential to enhance cognitive function, possibly by promoting long-term neuroplasticity and sustained mental clarity.
