ObjectiveTo evaluate the clinical effect of perineural platelet-rich plasma (PRP) injection for pain and numbness alleviation in diabetic peripheral neuropathy (DPN).Study DesignA randomized prospective clinical trial.SettingPain clinic and Rheumatology and Rehabilitation Departments, Assiut University Hospital.MethodsSixty adult patients with type II DM accompanied by DPN of at least six months' duration were assessed by modified Toronto Clinical Neuropathy Score (mTCNS) and randomly allocated into two groups. Group I underwent ultrasound-guided perineural PRP injection and medical treatment, and Group II received medical treatment only. Patients were followed up at months 1, 3, and 6 with regard to pain and numbness visual analog scale (VAS) and mTCNS scores.ResultsSignificant improvement was recorded in pain and numbness VAS scale scores in group I vs group II (P ≤ 0.001 during the whole study period for both parameters); at the same time, mTCNS improved in group I in comparison with group II with P = 0.01, 0.001, and <0.001 at months 1, 3, and 6, respectively.ConclusionsPerineural PRP injection is an effective therapy for alleviation of diabetic neuropathy pain and numbness and enhancement of peripheral nerve function.© 2019 American Academy of Pain Medicine.
