The role of sensory re-education of the brain in functional restoration of the hand after median nerve re-attachment
Keywords:
Median nerve, re-education, microsurgical techniqueAbstract
PURPOSE: The aim of this study is to prove the role of sensory re-education of patients after the restoration of complete, distal damage to the median nerve, through comparative tests between a group of retrained patients and a group of patients who did not participate into a similar re-education program.
PATIENTS - METHOD: In this study, a comparative evaluation of 63 patients (51 men and 12 women with a mean age of 38 years (20 -51)) with complete, distal median nerve transection and surgical restoration was performed among a group of patients who had sensory re-education and a group without re-education. Evaluation was done through re-education tests that began after successful reattachment and nerve regeneration. The clinical evaluation took place after 18 months, 3 years and 6 years.
RESULTS: From the statistical analysis, the conclusions obtained were that the individuals in the re-educationgroup displayed superiority in the sensoryrehabilitation and functional ability of the hand in a shorter time compared to the non-re-education group, in all the tests, especially in the test concerning the ability of recognition and location of the stimuli in the hand.
CONCLUSIONS: The damage to the median nerve leaves a significant sensory and functional disorder in the hand. Surgical restoration alone is not sufficient for the functional rehabilitation of the hand, which requires sensoryre-education in order to produce better results in a shorter time.
