摘要：Developmental plagiocephaly (DP) has been an increasing problem since the successful “back to sleep campaign”. The referrals for DP have increased by more than 400% during the years 2004 to 2008. Many infants spend less time in the prone position nowadays and some of the risk factors for DP are: tummy time less than 3 times per day, torticollis and slow achievement of motor milestones. Improved information for the parents is needed but also other strategies to prevent DP. This study is a continuum of an earlier pilot study;the aim was to investigate the effect of a pillow, designed to reduce pressure on the infant head. Method: Infants aged zero to two months were included in the study. They were randomized to either intervention group or control group. Head shape was investigated on two occasions, on the second occasion motor development, mobility and muscle function of the neck were also investigated. The parents were asked about tummy time and sleep position. All infants were investigated by the same physical therapist, blinded to group belonging. Result: Fishers exact test showed that it was more common with decreased CVAI among infants in the intervention group (P 0.001). Paired t test showed significant decrease in CVAI for the intervention group (P 0.002), but not for the control group (P 0.96). Conclusion: This study shows that a specially designed pillow can decrease DP in young infants.

摘要：Developmental plagiocephaly (DP) has been an increasing problem since the successful “back to sleep campaign”. The referrals for DP have increased by >400% during the years 2004 to 2008. Many infants spend less time in the prone position nowadays and some of the risk factors for DP are as follows: less than 3 times per day for the tummy time, torticollis and slow achievement of motor milestones. There is a need for better information to the parents but also for other strategies to prevent DP. The aim of this study was to investigate the effect of a special pillow and thus to reduce pressure on the infant head. Method: infants aged zero to two months were included in the study. They were randomized to either intervention group or control group. Head shape was investigated on two occasions, on the second occasion motor development, mobility and muscle function of the neck were also investigated. The parents were asked about tummy time and sleep position. All infants were investigated by the same physical therapist, blinded to group belonging. Result: seven infants had CVAI >3.5 on the last assessment, five of these had not used any method to reduce pressure. Fishers exact test showed a tendency where infants with reduced pressure on the head had less DP (P 0.08). Paired t test showed significant decrease in CVAI for the infants who had had reduced pressure on the head (P 0.01). Among these infants the CVAI was zero for 47% in the last assessment. For the infants who had not had a reduction of pressure on the head, there was no indication of a decrease of CVAI (P 0.45), and only 12% of these infants had a CVAI that was zero in the last assessment. Conclusion: this pilot study shows that a specially designed pillow may prevent DP in young infants. However, a larger sample is needed to confirm or disprove this. The study is planned to go on until there are 200 participants.

摘要：Analysis of functional MRI (fMRI) blood oxygenation level dependent (BOLD) data is typically carried out in the time domain where the data has a high temporal correlation. These analyses usually employ parametric models of the hemodynamic response function (HRF) where either pre-whitening of the data is attempted or autoregressive (AR) models are employed to model the noise. Statistical analysis then proceeds via regression of the convolution of the HRF with the input stimuli. This approach has limitations when considering that the time series collected are embedded in a brain image in which the AR model order may vary and pre-whitening techniques may be insufficient for handling faster sampling times. However fMRI data can be analyzed in the Fourier domain where the assumptions made as to the structure of the noise can be less restrictive and hypothesis tests are straightforward for single subject analysis, especially useful in a clinical setting. This allows for experiments that can have both fast temporal sampling and event-related designs where stimuli can be closely spaced in time. Equally important, statistical analysis in the Fourier domain focuses on hypothesis tests based on nonparametric estimates of the hemodynamic transfer function (HRF in the frequency domain). This is especially important for experimental designs involving multiple states (drug or stimulus induced) that may alter the form of the response function. In this context a univariate general linear model in the Fourier domain has been applied to analyze BOLD data sampled at a rate of 400 ms from an experiment that used a two-way ANOVA design for the deterministic stimulus inputs with inter-stimulus time intervals chosen from Poisson distributions of equal intensity.
