The rehabilitation treadmill has a special harness with two actuators on either side of the patient when in use. Interface suggests installing their Two WMC Sealed Stainless Steel Miniature Load Cells to the actuators, which will measure the forces applied on the pelvis of the patient. Force results can be measured using the SI-USB4 4-Channel USB Interface Module, which can also be graphed and logged on the customer’s computer with supplied VS3 software.
