Beschreibungen/Notizen

• Tendon transfer of the tibiliais posterior muscle is a surgical intervention widely employed in orthopedics for the correction of drop foot caused by leprosy. However, few models have proposed a thorough investigation of the brain plasticity phenomenon during tendon transfer. Thus, the present study aimed at analyzing EEG spectral coherence (SC) in patients submitted to tendon transfer of the tibiliais posterior muscle by Srinivasan's technique and quantitative EEG (EEGq). The sample consisted of four subjects with drop foot caused by leprosy. The SC parameter was evaluated in two experimental moments: pre and post-surgery. Results demonstrated a main moment effect for the C3-CZ electrode pair. Specifically, a significant increase in coherence values was observed. However, the ANOVA did not indicate a significant band/moment interaction. It can be assumed that coherence augmentation indicates that functional rehabilitation promoted by this specific surgery yields cortical alterations.
