Pain free socks
A recent study conducted at Veterans Administration Medical Center, Long Beach was published in the BMC Complementary and Alternative Medicine journal found specially designed socks modified the skin's reaction to light and reduced chronic pain. The goal of this study was to evaluate prospectively whether socks made from polyethylene terephthalate (PET) incorporating optically active particles (Celliant™) ameliorates chronic foot pain resulting from diabetic neuropathy or other disorders. Using a double-blind, randomized trial subjects twice completed the Visual Analogue Scale (VAS), Brief Pain Inventory (BPI), McGill Pain Questionnaire (MPQ), and SF-36 a week apart before receiving either control or Celliant™ socks. The same questionnaires were answered again one and two weeks later. The questionnaires provided nine scores for analyzing pain reduction: one VAS score, two BPI scores, five MPQ scores, and the bodily pain score on the SF-36. Mean scores were compared to measure pain reduction. The statistical analysis revealed subjects wearing Celliant™ reported less pain. The researchers concluded socks with optically modified PET (Celliant™) appear to have a beneficial impact on chronic foot pain. The mechanism could be related to the effects seen with illumination of tissues with visible and infrared light. Celliant™ is a polymer fabric constructed from polyethylene terephthalate (PET) yarn containing optically active particles – a proprietary mixture of natural and inorganic materials – which scatter and reflect visible and near infrared light. Garments constructed with such optically modified fibres are thought to influence transmission and reflectance of electromagnetic energy into underlying tissue and skin.
