Table 2. Comparison of the motor block characteristics between Group L and Group R.

When all four parameters of the motor block of the two study groups were compared, the results were in favour of Group L with a statistically significant difference in all parameters.

Group L: levobupivacaine group; Group R: ropivacaine group

Motor block characteristics	Group L (n=33)	Group R (n=33)	P-value
Time taken for the onset of motor block (in min)	5.4±0.72	6.3±0.80	0.003
Time to reach Bromage score 3 (in min)	6.9±0.75	8.2±0.70	0.02
Time to regress to Bromage score 1 (in min)	120±6.25	105±5.92	0.0005
Mean duration of motor block (in min)	148±26.40	132±28.75	0.0001
