Table 9 Functional scale score and changes in the three study arms \( \left(\overline{x}\pm SD\right) \)

Time	Arm 1 (n = 14)	Control arm (n = 14)	Arm 2 (n = 14)	P-value
Baseline	90.29 ± 4.00#	87.24 ± 3.89	88.60 ± 3.56	0.12
Day 7	91.56 ± 4.94	89.21 ± 4.16	90.35 ± 4.10	0.38
Follow up	90.79 ± 4.85	89.78 ± 3.53	90.48 ± 4.27	0.81
Main effect of time (P-value)*	<0.05

*There was no interaction between the changing trends of Functional scale scores and the three groups’ intervention factors over time
