  • Inflammation of the appendix
  • Pain in the lower abdominal region on the right side
  • Appendix can rupture when blocked by an object, tumor, or feces
  • Appendix is a tube of tissue off of the large intestine with an unknown function

Essentials of Diagnosis

  • Right abdominal and side (flank) pain
  • Positive cultures
  • McBurney’s point, tip of right 12th rib tenderness
  • Palpation over appendix
  • Lab tests

General Considerations

  • If untreated can possibly rupture
  • Possible referred pain to back, pelvic region, or rectal area (in men)
  • Possible secondary problems that may, depending on severity, indicate the need for physical therapy intervention
    • Impairment of aerobic capacity and muscle endurance
    • Sarcopenia
    • Musculoskeletal problems
    • Neuromuscular problems
    • Weight loss
  • May mimic colon cancer or tumors, irritable bowel, colitis or, in females, gynecological problems such as endometriosis, uterine fibroids, or ectopic pregnancies
  • Symptoms are frequently referred to the back and abdominal areas, so it may be common to have patients inappropriately referred to PT.
  • Pseudoappendicitis: Yersinia enterocolitica


  • Can occur across the lifespan, from 2 years old and up1
  • Most common in individuals between 15 and 30 years of age1

Signs and Symptoms

  • High fever
  • Diarrhea
  • Shaking and chills
  • Nausea
  • Vomiting
  • Discomfort or sharp pain in the right lower quadrant of the abdominal area
  • Abdominal tenderness and guarding of the right lower quadrant
  • McBurney’s point, tip of right 12th rib tenderness
  • Pain in the belly button region without trauma
  • Right, low back pain without trauma, insidious onset
  • Difficulty standing up ...
