Disclaimer – We are not physicians and therefore cannot provide medical advice.

People with lower limb injuries experience a higher instance of blood clots (DVT) than the general population. One reason for this is because return blood flow from the lower extremities to the heart requires muscle contraction. Peripheral veins in the legs have one-way valves that direct flow away from the limb and toward the heart. In simple terms, the heart delivers blood flow to the lower extremity; contraction of the leg muscles pumps the blood back to the heart. This is called the Venous Pump Mechanism, and this is why it’s recommended to get up and walk around every couple of hours when on long flights.
When using crutches, the muscles in the injured leg are largely inactive, therefore the return blood flow is restricted, which can contribute to blood clots. Also, people tend to be less physically active when they use crutches or scooters, which also results in leg muscle inactivity.
In contrast, when using the iWALK the upper leg muscles of both legs are clearly active. EMG (Electromyography) studies have indicated passive firing of the lower leg muscles of the injured leg also. What this means is that the mechanism for return blood flow is being utilized when using the iWALK, and to a higher degree than with other mobility devices.
While it is conceivably possible to over-tighten the straps to the point that it creates a tourniquet, discomfort would likely prevent you from doing this. It is essential that the straps are tight, however, with the proper setting you can still, with gentle force, slip a finger between the strap and your leg.
We have been producing various versions of the iWALK crutch for over 20 years. In that time, we have not had a single case where DVT was attributed to the use of the iWALK. In addition, iWALK crutches are referred by orthopedic surgeons in the top hospitals in the country. Click here to see what doctors are saying.
