Morphol. [online]. 2009, vol.27, n.3, pp. 699-703. ISSN 0717-9502. doi: 10.4067/S0717-95022009000300012.
The fibularis longus muscle (FLM) has an important role in the movement of eversion of the foot and in maintaining the plantar arch. The electrostimulation procedures seek to maintain muscle trophism, increase strength and endurance, and are frequently used in physiotherapy, for which the clinician needs to know the location of the motor points of the FLM. Therefore, the purpose of this study was to determine the number and distribution of motor points of the FLM and relate them to observable parameters in the surface anatomy. Ten formalin-preserved limbs were used, and the lateral regions of the leg were dissected in detail. In all the cases, the muscle presented three fascicular patterns, the superior and anteroinferior fascicles presented two motor points each, while the posteroinferior fascicles were between 2 and 3 motor points. Our results suggest that there is a pattern of distribution of the superficial fibular nerve, whose knowledge is useful for clinical application in the FLM electrostimulation proceedings.
