Low frequency impedance allows a healthcare professional to assess and monitor:
- The presence of lymphoedema by comparing a patient’s results to a normal range established in a healthy population. Research has shown that detection of lymphoedema can be achieved 1-4 months and up to 10 months earlier by this methodology .
- The extent of the condition by indicating variance outside the normal range.
- The change from a pre-surgical baseline measurement.
- The “Target” range and when appropriate therapeutic intervention is clinically indicated.
- The effect of therapeutic intervention to document efficacy of care.
Current literature suggests pre-surgical assessment of limbs as a preferred method for early detection and therapeutic intervention of lymphoedema. This proactive approach serves to inhibit the severity and chronicity of this impairment.
Current clinical practice for the assessment and monitoring of lymphoedema is mostly limited to symptom assessment and circumference measurements.
When we compare bioimpedance to current clinical practice, we note that bioimpedance is an evidence based assessment and monitoring tool that is more reliable, more efficient (faster) and more objective than those used routinely today.
The tape measure is relatively slow and subject to operator error.
Palpation and symptom assessment, while important has difficult in detecting the early stages of lymphoedema.
KEY POINTS about screening for Lymphodema with bioimpendance spectroscopy
4-fold increase in sensitivity over the tape measure.
1-4 months and up to 10 months earlier detection.
Provides a targeted standardised metric.
