Myofascial syndrome is a common cause of chronic musculoskeletal pain and results in dysfunction of the affected muscles. It is characterized by myofascial trigger points (MTPs) which are clinically identified by palpation of a muscle or fascial taut band. Previous publications have found MTPs to coincide with neuromuscular junctions at the innervation zone (IZ). The fibularis longus syndrome is one of the most frequent myofascial syndrome of the lower limbs and occurs due to a wide variety of etiologies, most commonly, overuse and ankle sprain. Referred pain and tenderness caused by the trigger points of the FL muscle are located above, behind and below the lateral malleolus and may extend along the lateral aspect of the foot and leg.
