Intercostal Muscle Strain
Symptoms include intense sharp, stabbing, tight, spasm, stiffness, dull, deep ache and point tenderness in the intercostal space.
Shallow breathing due to inability to perform deep breathing.

Symptoms are intensified by stretching, deep inhalation, sneezing and coughing.
Limited range of motion in all planes due to pain and muscle guarding.
Slow and guarded motions. Apprehensive to move.
Altered posture and/or Antalgic position.

Mechanism of Injury: Sudden concentric contraction of intercostals in stretched position or during activities involving excessive or repetitive lateral flexion or rotation.
Baseball, javelin, rowing and ice hockey.

May occur traumatically due to direct impact forcing ribs apart.
Treatment recommendations include chiropractic care and massage.
Intercostal muscular strain is the most common cause of muscular chest wall pain, accounting for up to 50% of cases. Risk increases during intense training or resumption after a prolonged period of rest (offseason). Among MLB players, strains of the intercostal or external/internal oblique muscles accounted for 92% of trunk muscular strains.

Intercostal Muscles: Anatomy
Mainly involved in the mechanical aspect of breathing. Function to expand and decrease size of chest cavity to facilitate breathing. Three layers.
External Intercostal Muscles: Aid in normal and forced inhalation.
Origin: Ribs 111. Insertion: Ribs 212. Action: Ribcage expansion through elevation and separation of ribs.
Internal Intercostal Muscles: Aid in forced expiration. Origin: Ribs 212. Insertion: Ribs 111. Action: Decrease transverse dimensions of ribcage through rib depression and inward bending.
Innermost intercostal muscle: Deepest layer of internal intercostal muscles. Separated by a neurovascular bundle.
