Preoperative electrophysiological evaluation and postoperative clinical and functional outcomes in brachial plexus injury after surgical neurolysis

Introduction/Aims: Electrophysiological and clinical Correlation of pre- and post-operative analysis in BPI surgical management through the use of Neurolysis.

Methods: An ambilective quasi-experimental analytical study was carried out. In order to determine the prognostic value of the preoperative electrophysiological analysis in the clinical and functional recovery after surgical intervention. the study was approved by the Hospital's research and bioethics committee (DI/16/403/03/152), the informed consents were obtained and signed by all the patients included. A Wilcoxon test was performed in search of significant clinical and functional changes after surgery, and a Spearman Correlation test was realized between the preoperative electrophysiological variables and postoperative clinical and functional outcomes. Value α = 0.05 and β = 0.01.

Results: Twenty patients were studied. Postoperative clinical evaluation showed significant changes in terms of pain (∆79.95%, p = 0.034), u...
