Abstract: This study investigated a new method for the improvement of blood flow for preventing deep vein thrombosis (DVT) via the combination of intermittent pneumatic compression (IPC) and ankle-assist exercises. Previous studies developed an endoskeletal DVT prevention device that combined a stretchable pneumatic actuator and IPC and was validated in the supine and seated positions. However, the combination methods examined till date were not optimal for practical use; moreover, only one pattern of compression and timing of ankle joint movement was used. Therefore, this study clarified the effective compression range of the IPC. Further, the effect of the improvement in blood flow through variations in the compression pattern and timing of the ankle joint motion was experimentally evaluated. Consequently, compression around the calf was confirmed to be the most effective in improving blood flow. Further, compression during muscle relaxation was found to be effective. In addition, the three proposed compression patterns were found to be as effective as the conventional compression patterns and exhibited superior blood flow improvement in 10 subjects.
