Primary Outcome Measures

Name	Time	Method
the Sum of Pain Intensity Differences in Pain Score Over 48 Hours in the rest state	48-hours	Pain intensity will be evaluated using an 11-point (0-10) Numeric Pain Rating Scale (NPRS), with higher numbers indicating a higher pain intensity, administered over 48 hours. Time weighted average change from baseline is calculated using the following: time weighted sum of pain intensity differences (SPID) divided by a constant (48 hours) to yield values on the 0-10 NPRS.

Secondary Outcome Measures

Name	Time	Method
Cumulative use of remedial analgesics from 0h to 48h	48-hours
Investigator satisfaction score for analgesia treatment	48-hours
Participant ' satisfaction score for analgesia treatment	48-hours
Time of first use of remedial analgesic medication	48-hours
the Sum of Pain Intensity Differences in Pain Score Over 6、12、24、 48 、12-24、24-48 Hours under static and moving condition	48-hours
