Rectus Sheath Spasm

Rectus sheath spasm is a condition involving involuntary contractions and tightness of the rectus abdominis muscle, located in the front of the abdomen. This muscle is crucial for movements such as bending and twisting and plays a significant role in core stability.

Types of Rectus Sheath Spasm

  1. Acute Spasm: Sudden onset, often due to injury or intense physical activity.
  2. Chronic Spasm: Persistent spasms that may result from repetitive strain or underlying conditions.
  3. Localized Spasm: Spasms confined to a specific area of the rectus abdominis.
  4. Generalized Spasm: Spasms affecting the entire length of the rectus abdominis muscle.
  5. Nocturnal Spasm: Spasms occurring primarily at night.
  6. Exertional Spasm: Spasms triggered by physical exertion.
  7. Referred Spasm: Pain and spasm perceived in the rectus abdominis but originating from another part of the body.
  8. Idiopathic Spasm: Spasms with no identifiable cause.
  9. Neuropathic Spasm: Spasms due to nerve irritation or damage.
  10. Ischemic Spasm: Spasms resulting from reduced blood flow to the muscle.
