What does the assessment of fetal tone in a BPP indicate?

The assessment of fetal tone in a Biophysical Profile (BPP) evaluates the presence of active fetal movement, which is a key indicator of fetal well-being. When fetal tone is assessed, healthcare providers observe the fetus's movements, including flexion and extension of the extremities. The presence of active movements suggests that the central nervous system is functioning properly and that the fetus is receiving adequate oxygen and nutrients. This is crucial because a well-oxygenated fetus is typically more active.

In contrast, insufficient movements or decreased fetal tone may indicate potential issues, such as hypoxia or other underlying fetal problems. Thus, the assessment of fetal tone provides valuable insights into the overall health and status of the fetus, reinforcing that active fetal movement indicates well-being.
