It is non-invasive, easy to handle, well-suited for repetition and standardization, and there is no strain for the patient. This method is appropriate for global assessment of calf pump insufficiency regardless whether it may be caused by varicosis, postphlebitic syndrome, or deep venous thrombosis. With the application of tourniquets, LRR helps to predict the possible result of vein stripping and is likewise useful for the follow-up period. LRR promises to become a valuable screening method regarding the detection of deep venous thrombosis of the lower leg. A useful methodic variation is the passive manual compression of the calf instead of active dorsiflexion; thus the measurement becomes independent of the patient's cooperation. We must take into account, however, the high sensitivity of LRR depending on various known and still unknown factors. The measured values may differ to a considerable degree in one single patient, even under exact conditions of examination. Therefore we always perform three measurements and then take the average value. Critically applied, LRR represents a valuable technique of quantitative phlebological examination.
