 Some trials have shown that increasing the blood flow in the legs over time using medical devices intermittent pneumatic compression, muscle stimulators, in addition to maximal medical and surgical therapy, can increase claudication distance, absolute walking distance, decrease rest pain, and reduce amputation rates. In our unit it has become apparent that there are an increasing number of medical devices available for circulatory support, either for use as an inpatient, out-patient, or a member of the general public. The supporting evidence for these is variable in scientific and clinical content or relevance, and requires clinical trials to evaluate further.
