RESUMO
The aim of this study was proposing gamma band activity (GBA) as an index of training-related brain plasticity in the motor cortex. Sixteen controls underwent an experimental session where electroencephalography (EEG) activity was recorded at baseline (resting) and during a motor task (hand movements). GBA was obtained from the EEG data at baseline and during the task. Index of plasticity (IP) was defined as the relationship between GBA at the end of the motor task (GBAM_FIN), divided by GBA at the beginning of the task (GBAM_INI) for movements of both hands. There was a significant increase in GBA at the end of the task, compared to the initial GBA for the motor task (GBAM_FIN > GBAM_INI). No differences were found at baseline (GBAB_FIN ≈ GBAB_INI). Individual IP values had a positive (r = 0.624) and significant correlation with subject's handedness. Due to plastic changes, GBA could indirectly but objectively reveal changes in cerebral activity related to physical training. This method could be used as a future diagnostic test in the follow-up of patients undergoing rehabilitation. It could also have potential applications in the fields of sports medicine.

INTRODUCTION: Pudendal nerve entrapment syndrome is a poorly known condition and thus rarely included in our differential diagnoses. First described by Amarenco in 1987. DEVELOPMENT: The symptomatology is varied and can be confused with other entities, in particular the pelvic floor myofascial syndrome. CONCLUSIONS: The main symptom is neuropathic pain in the perineal area. The diagnosis is based on the clinical history, physical examination and the confirming neurophysiologic tests.

Introducción. El síndrome de atrapamiento del nervio pudendo es una entidad poco conocida que raras veces se incluye en el diagnóstico diferencial. Fue descrito por primera vez por Amarenco en 1987. Desarrollo. Presenta una sintomatología tan variada que puede simular otras patologías, especialmente el síndrome miofascial del suelo pélvico. Conclusión. El síntoma capital es el dolor neuropático en la región perianal. El diagnóstico se basa en la historia clínica, la exploración física del suelo pélvico y las pruebas neurofisiológicas confirmatorias (AU)
