The percentage change (median and IQR) for each of the test variables for placebo and bupivacaine interventions
| Placebo | Bupivacaine | |||
|---|---|---|---|---|
| Change expressed as a percentage Median (IQR) | Significance of difference due to intervention | Change expressed as a percentage Median (IQR) | Significance of difference due to intervention | |
| Negative signs represent a worsening for postural sway and proprioception but an improvement for MVC and percentage activation. | ||||
