Which of the following is a physiological effect of vibration on patients?

  1. Improved oxygenation

  2. Dyspnea and abdominal pain

  3. Enhanced circulation

  4. Decreased heart rate

The correct answer is: Dyspnea and abdominal pain

Vibration therapy is known for several beneficial physiological effects on patients, one of which is enhanced circulation. When vibration is applied, it can stimulate blood flow by inducing rhythmic contractions of blood vessels and skeletal muscles, thereby improving venous return and overall circulation. This effect can help in delivering more oxygen and nutrients to tissues while also assisting in the removal of metabolic waste products, which is particularly beneficial in various therapeutic settings. The response of dyspnea and abdominal pain does not align with the positive physiological effects typically associated with vibration. Rather, such symptoms would suggest discomfort or distress in the patient, which is counterproductive to the therapeutic goal of promoting relaxation and physiological stability through vibration. Therefore, enhanced circulation is the physiological effect that accurately reflects the benefits of vibration therapy on patients.
