Table 2.

Total STEP scores and specific STEP items between responder and non-responder infants who had both pre- and post-STEP scores; Mean (SD)

	Responders (full PO Feed) (n = 7)	Non-responders (G-tube) (n = 12)	P-value

GA at pre-STEP	41.5 ± 1.8	41.8 ± 3.2	0.83
GA at post-STEP	44.3 ± 2.5	44.9 ± 2.9	0.66
Total pre-STEP scores	12.6 ± 1.6	14.6 ± 3.0	0.12
Total change in STEP scores ^a	1.7 ± 2.1	0.0 ± 0.85	0.04^*
Head in supine with visual stimulation ^a	0.35 ± 0.31	0.03 ± 0.30	0.03^*
Head in supine with no visual stimulation ^a	0.22 ± 0.26	0.00 ± 0.14	0.03^*
Head movement rolling by arm ^a	0.22 ± 0.21	0.07 ± 0.19	0.14
Head movement supported sitting ^a	0.39 ± 0.32	0.03 ± 0.21	0.01^*

Data presented as difference in means (post item score - pre item score) ± standard deviation.

Significant at P < 0.05 level.

Change in STEP scores divided by weeks between STEP, normalized by weeks of development. Independent t-test was used in all analysis.
