The stimulation testing protocol performed in the clinic after a mean follow-up period of 19 months. CPT = Cold pain threshold; HPT = hot pain threshold, CDT = cold detection threshold; WDT = warm detection threshold; MH = mechanical hypersensitivity; DA = dynamic allodynia. The mean time period to achieve stabilisation of pain scores is provided along with the standard error (SE) to the nearest minute above each section. Stimulation off times had to be individualised to minimise patient discomfort as per ethical approval.
