简要总结
The hypotheses of this study are as follows:
- There is no significant muscle activity difference of each muscle in patients between pre and post operation.
- There is no significant forward reach distance/average velocity difference in patients between pre and post operation.
- 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.
- There is no significant muscle activity difference between muscles on both sides at post operation.
详细描述
30 healthy adults and 30 patients is going to undergo lumbar fusion surgery will be recruited in this study. The assessment will be held before surgery, two months, three months and six months after surgery. Visual pain scale and passive range of motion over lumbar, hip, knee, ankle joint of each subjects will be recorded. Then the maximum voluntary contraction at lower extremity will be measured by electromyography. Finally, the subjects will be asked to do forward reach by dominant upper limb/bilateral upper limbs/arm crossed in the front of chest for three times in standing and sitting position after five practices. The motion data will be collected by 3-dimension video and the muscle activity by electromyography.
