NCT01585337

Brief Summary

The hypotheses of this study are as follows:

  1. 1.There is no significant muscle activity difference of each muscle in patients between pre and post operation.
  2. 2.There is no significant forward reach distance/average velocity difference in patients between pre and post operation.
  3. 3.There is no significant standard deviation of center of pressure (COP) along x axis, speed of COP along y axis during the task and COP path during the 3-sec holding phase difference in patients between pre and post operation.
  4. 4.There is no significant muscle activity difference between muscles on both sides at post operation.
