This study investigated if the proper pressure level on the wrist tendon area and muscle area of the lower arm are within the same range by examining the responses of blood flow and subjective evaluation. Subjects consisted of 18 males in their 20s, and the experimental bands were custom-made by applying size measurements of each subject. In the experiment, a total of 5 steps were selected by reducing 10 (Step 1) to 50 (Step 5)% from the original body size in the circumferential direction. Blood flow was measured with a sensor attached to the tip of the finger inside the right hand while sitting in a chair for 15 minutes. Blood velocity began to increase (0.82 kPa) when the wrist circumference around tendon area was reduced by 20% (Step 2) and reached its maximum (1.72 kPa) at Step 4. However, the preferred subjective pressure was 1.36 kPa, which was less than the maximum pressure value of 1.72 kPa for Step 4. Blood velocity began to increase when pressure on the muscle area was 1.38 kPa and reached its maximum at 2.16 kPa; however, the most preferred clothing pressure was 1.71 kPa. The results of this study showed that the appropriate pressure level was higher in the muscle area than in the wrist tendon of the lower arm and indicated that graduated compression is favorable.
