Clinical Details
Official title: A Randomised, Double-blind, Placebo-controlled, Three-way Cross-over Single Center Study to Characterize the Phenotype in Patients With Morton's Neuroma and to Explore the Effect of Local Administration of Xylocaine (Lidocaine)
Study design: Allocation: Randomized, Endpoint Classification: Pharmacodynamics Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Basic Science
Primary outcome: The baseline phenotypic Quantitative sensory testing (QST) variables (e.g. heat, cold, touch and mechanical pain perception). Sensory tests will be performed to measure pain and skin sensitivity by use of different pressure (mN) and temperature ( C)The baseline phenotypic Quantitative sensory testing (QST) variables (e.g. heat, cold, touch and mechanical pain perception).
