FIG. 4.

Changes in maximum finger flexion force (MFFF) for 10 subjects in the acupuncture group (the left box, LU 11; the second box from the left, PC 9; and the third box from the left, SI 1) and control group (the right box in each timepoint). Vertical axis is the percentage of 10 minutes (min) before value of MFFF and the horizontal axis is time. The top, middle, and bottom lines of the boxes correspond to the 75th, 50th (median), and 25th percentiles, respectively. The whiskers extend from the minimum to the maximum value. The circles indicate the arithmetic mean. The broken line represents baseline (10 min before value of MFFF). *p<0.05, **p<0.01.
