Nice study by Dahlin et al. out of Sweden showed improved glucose control as measured by Hb A1c levels led to improved vibration perception threshold (VPT) in Type I diabetes patients. This is yet another paper implying improvement in neurological function is possible in those patients with diabetic peripheral neuropathy (DPN). This goes against long held dogma that DPN is largely irreversible. Interestingly, one of the more sensitive frequencies used in Dahlin’s study was 64 Hz, one of the frequencies available in our ETFMx.
