This interaction is graphed in Figure 1 and shows beneficial effects of music/adapted ATVV stimulation for females but not for males.
The graph shows a delayed, but increasing rate of tolerance for those male and female infants who required a longer hospital stay and received up to 6 days of music/adapted ATVV stimulation.
This study has demonstrated that music/adapted ATVV stimulation can be particularly effective in this capacity and may be indicated for premature infants in intensive care, especially female infants.
In NBICU health care services, the music/adapted ATVV protocol might be used regularly by parents, cuddlers, and nurses from around 30-32 weeks gestation to discharge.
A significant Group effect was identified for PR (p [less than] .001), reflecting a modest increase for Groups T, ATV, and ATVV. In general, infants showed stronger responses on successive days, indicated by significant main effects for days for PR (p [less than] .001) and RR (p = .01).
PR for Groups ATV and ATVV were not different from controls.
Except for the ATVV group, alertness evolved into sleep within the first 5 minutes postintervention, although this trend failed to reach significance.
Group ATVV exhibited a unique sleep pattern involving only a gradual increase in alertness during intervention (11%, 240 observations), followed by increasing alertness that was sustained over the 30-minute postintervention (24%, 280 observations) (see Table 4).
Only Groups T and ATVV had sufficient variability to warrant further analyses of PR and RR.

The findings of a 6 bpm increase in HR, a 4-respiration per minute decrease in RR, and .45% decrease in Sa[O.sub.2] replicate and extend recent demonstrations of the safety of the ATVV. White-Traut and Goldman (1988) reported that 35-week infants had a mean 12 bpm increase in HR and a mean of 5 breaths per minute RR increase while receiving the ATVV, whereas 33-week infants had a 6.5 bpm increase in PR (White-Traut et al., 1993).
