	S0	S1	S1+	S2	S2+	S3	S3+	S4	P-value
Experimental group									0.006**
Before treatment	0	2	2	3	5	0	0	0
After treatment	0	0	1	4	2	3	2	0
Control group									0.034*
Before treatment	0	3	3	5	0	0	0	0
After treatment	0	1	3	5	2	0	0	0

A higher grade indicates a better level of functioning. Recovery above grade S2 was considered good. Data were analyzed by Wilcoxon signed-rank test. *P < 0.05, **P < 0.01, vs. before treatment.
