Background

The detection of motor problems in infancy requires a detailed assessment method that measures both the infants' level of motor development and movement quality.

Aim

To evaluate the ability of the Structured Observation of Motor Performance in Infants (SOMP-I) to detect cerebral palsy (CP) in neonatal intensive care recipients.

Study design

Prospective cohort study analyzed retrospectively.

Subjects

212 (girls: 96) neonatal intensive care recipients (mean gestational age 34 weeks, range: 23–43). Twenty infants were diagnosed with CP.

Outcome measures

The infants were assessed using SOMP-I at 2, 4, 6 and 10 months' corrected age. Accuracy measures were calculated for level of motor development, quality of motor performance and a combination of the two to detect CP at single and repeated assessments.

Results

At 2 months, 17 of 20 infants with CP were detected, giving a sensitivity of 85% (95% CI 62–97%) and a specificity of 48% (95% CI 40–55%), while the negative likelihood ratio was 0.3 (95% CI 0.1–0.9) and the positive likelihood ratio was 1.6 (95% CI 1.3–2.0). At 6 months all infants with CP were detected using SOMP-I, and all infants had repeatedly been assessed outside the cut-offs. Specificity was generally lower for all assessment ages, however, for repeated assessments sensitivity reached 90% (95% CI 68–99%) and specificity 85% (95% CI 79–90%).

Conclusions

SOMP-I is sensitive for detecting CP early, but using the chosen cut-off can lead to false positives for CP. Assessing level and quality in combination and at repeated assessments improved predictive ability.

Abstract [en]

AIM: Methods are needed to evaluate the level of early motor development and quality of motor performance in infants. We examined the convergent and discriminant validity of the Structured Observation of Motor Performance in Infants (SOMP-I) for evaluating the level of motor development and quality of motor performance in preterm and term infants.

METHODS: A regional cohort of 111 preterm infants with a gestational age of <32 weeks and 72 healthy term born infants were assessed with the SOMP-I, at two, four, six and 10 months of corrected age. Convergent validity was analysed with a mixed model analysis of the motor performance over time. Discriminant validity was analysed with the Mann-Whitney U-test in groups with different neonatal characteristics.

RESULTS: Convergent validity was supported, as the level of motor development increased with age and the quality of motor performance improved over time. The method discriminated for both level and quality between the preterm and the term infants. The preterm infants demonstrated different quality deficits regardless of the level of motor development.

CONCLUSION: Convergent validity and discriminant validity of the SOMP-I were supported in preterm and term infants and facilitates early identification of infants with atypical motor development.
