These muscles can become strained due to rapid movements that bend or twist the upper body suddenly.
The external intercostal muscles help to form the chest wall and move the ribs upward, increasing the thoracic cavity space, during the act of inspiration. The external intercostal muscles are innervated by the intercostal nerves. Conditions that can afflict the external intercostal muscles include costochondritis, pleurisy, myalga, repetitive strain injury, tears, strains, myopathy, atrophy, infectious myositis, neuromuscular diseases, lacerations and contusions.
