Amini M, Aliabadi F, Alizade M, Kalani M, Qorbani M. The relationship between motor function and behavioral function in infants with low birth weight. Iran J Child Neurol. 2016;10(4):49-55. Performance on the TIMP and the Brazelton Scale was compared in 50 infants under 2 months CA.  Statistically significant relationships were found between TIMP observed item performance and Brazelton items involving social interaction, state organization and regulation, and reflexes, and between TIMP elicited item performance and all Brazelton items except habituation. Notably each increase of 1 point in autonomic function was related to an increase of 18 points on elicited items of the TIMP. The authors conclude that Brazelton scores can be used to predict motor function.  http://dx.doi.org/10.22037/ijcn.v10i4.10965

Cheatham SL, Carey H, Chisolm JL, Heathcock JC, Steward D. Early results of neurodevelopment following hybrid stage I for hypoplastic left heart syndrome. Pediatr Cardiology 2015;36:684-691. In 18 subjects who had undergone Hybrid Stage I palliation for hypoplastic left heart syndrome, development on the TIMP at 2 months fell on average between -1 and -2 SDs below the mean. At 4 months delay was still evident with TIMP scores averaging between -.5 and -1 SD below the mean. Development on the Bayley III motor scale was also delayed still at 6 months and attention to intervention is recommended for these infants.  http://dx.doi.org/10.1007/s00246-014-1065-5

TIMP scores at term and 12 weeks corrected age (CA) in 22 infants born preterm between 24 and 35 weeks GA were used to determine a useful 10-item screening set at each age that is proposed to provide good prediction of those at high/low risk for poor developmental outcome as measured with the Bayley III at 12 months CA.

Neonatal Network 2010;29(6):359-366.  Both a 10-day (15 min per day, twice a day) whole body stimulation program and a stimulation program that also included oral stimulation beginning at approximately 32 weeks PMA improved outcomes on the TIMP in comparison with a control group or an oral stimulation only group in a study of 75 preterm infants (GA between 26 and 32 wks at birth) randomly assigned to treatment groups. The groups with full body stimulation had only 10% of infants with scores below -1 SD while 40% of control infants and 37% of oral stimulation only infants scored below average. http://dx.doi.org/10.1891/0730-0832.29.6.359

Giachetta L, Nicolau CM, Juliani RCTP, de Carvalho WB, Krebs VLJ. Characterization of the motor performance of newborns in a neonatal unit of tertiary level. Rev Assoc Med Bras 2016;62:553-560.  The TIMP was used to assess infants between 34 and 41 weeks CA. Early age groups showed average TIMP scores compared to U.S. TIMP norms, but infants between 38-41 weeks were statistically lower performers than the reference values. Mothers of infants in the latter group were found to have higher rates of smoking, infection, and diabetes. No subject in this group of relatively low risk infants (no chronic lung disease or brain insult) scored in the below average or lower range. Authors concluded that the TIMP is useful clinically and can be used safely in tertiary care units. http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0104-42302016000600553&lng=en&tlng=en

Infants in a randomized controlled study who had below average TIMP scores at study entry gained more on the TIMP and experienced earlier hospital discharge following massage therapy than a sham treated group.

Early Hum Dev 2012;88:39-43.  The TIMP and the GMA were performed at 34 weeks PMA in 37 high risk preterm infants with GA at birth 24-33 weeks and the AIMS and PEDI were used at 14 months to assess outcomes in 32 infants. Thirty-two percent of infants had poor repertoire and 19% had cramped-synchronized GMs. All of these high risk infants had delayed scores on the TIMP (one was in the low average range with normal GMs). TIMP scores were not correlated with GMs indicating that the TIMP and GMA are not assessing the same construct. TIMP results were not correlated with outcome at 14 months, confirming previous research showing that the TIMP at preterm age is not predictive of later outcome; there was only a fair to moderate correlation of GMs with outcome, thus a single GM assessment at preterm age cannot be used to predict outcome either.  http://dx.doi.org/10.1016/j.earlhumdev.2011.06.013

Study of concurrent and predictive validity of the TIMP and the AIMS in 95 infants born at < 30 weeks GA or under 1000 gms.

A cutoff Z score of -1.0 on the TIMP had a diagnostic agreement of 92% with an AIMS score <10th percentile. Neither test at 3 months CA predicted AIMS performance at 15 months.

Longitudinal development of infants born preterm (relatively low risk) and term was compared. Infants born preterm had higher scores than the full term group between 1 and 4 months of age, but there were no statistically significant differences and development was highly linear across time. Both groups performed on average below TIMP normative values between 1 and 3 months, but there were no statistically significant differences from TIMP norms. Infant born preterm showed relatively faster rate of development than those born at term from 0-1 month. http://www.scielo.br/pdf/rbfis/v14n5/en_a08v14n5.pdf

Mean HINT scores for infants at low risk were lower than mean scores for infants at high risk, as would be expected in that higher scores indicate higher risk. Significant differences were found at 4, 5, 7, and 8 months. At 6 months, there were no significant differences. There were not enough high-risk infants in other subgroups for reliable comparison.

A convenience sample (n=142 infants) was assessed at 4–6 months and 10–12 months of age using the HINT and Morrell’s Infant Sleep Questionnaire. Based on a cumulative risk index, three groups were defined: higher risk (n=28), lower risk (n=42), and no risk (n=72). At both ages, sleep scores were similar among the groups. In the no risk and lower risk group, sleep difficulties decreased with age, while for infants in the higher risk group, more difficulties were reported over time. Overall, neuromotor attainments were not related to sleep fragmentation or settling difficulties.

We examined concurrent validity of scores for the HINT and the AIMS in 121 Canadian infants. Relationships between the two tests for the overall sample were as follows: r = -.83 at 4 to 6.5 months (n = 121; p < .01) and r = -.85 at 10 to 12.5 months (n = 109; p <. 01), suggesting that the HINT, the newer of the two measures, is valid in determining motor delays.
