Hoffman sign evaluates for cervical myelopathies and upper motor neuron lesions. The examiner repeatedly flicks the volar or dorsal surface of the middle finger and observes the response. A positive test is identified by reflex contraction of the thumb and index finger.

Man-made EMFs introduce frequencies that the body doesn’t inherently recognize, which can interfere with the coherent signaling our cells rely on. In a world saturated with artificial, manmade electromagnetic signals, understanding how biological systems evolved to communicate through light and frequency is key to protecting long-term cellular health. My latest Substack article covers the full evidence base for EMF-related harm, the symptoms most practitioners miss, and the diagnostic framework
