Table 4. Comparison of berg balance scale (Unit: score)

Group	Pre	Post	Difference value	Time (P value)	Group×time (P value)	Group (P value)	t value	P value
EG	37.38±11.33	44.92±7.98	7.54±4.56	< 0.01*	0.01*	0.43	5.80	< 0.01*
CG	36.08±13.81	38.75±13.81	4.00±2.49	-	-	-	2.32	0.04*

EG: experimental group (with small props).
CG: control group (without small props).
Pre: before intervention (mean ± standard deviation).
Post: after intervention (mean ± standard deviation).
Difference value: change between pre and post.
Time (P value): P-value for within-group change over time.
Group×time (P value): P-value for interaction between group and time.
Group (P value): P-value comparing groups (post–pre difference).
P value (Bonferroni adjusted, α = 0.025): Bonferroni-corrected p-value for multiple comparisons.
P < 0.05.
