It has been reported that passive training consisting of knee flexion/extension in a kinetic machine has a beneficial effect on up regulation of growth factors, remicrovascularization and improved blood flow. Høier et al described that passive movement of the leg induced a two-fold elevation in blood flow, elevation of angiogenic factors and initiates capillarization in skeletal muscle. All three factors are often impaired in the diabetic leg, which results in poor wound healing.
