Development of a new screening tool for neuromotor development in children aged two – the neuromotor 5 min exam 2-year-old version (N5E2)

Abstract Objective As a new screening tool for neuromotor development in children aged two, we developed the Neuromotor 5 min Exam 2-year-old version (N5E2), which can be easily administered by pediatricians or primary care physicians. In this study, as an initial attempt to examine the utility of the N5E2, the inter-rater reliabilityon scoring for the individual items in this scale was assessed. Methods The participants of the study were 29 children (aged 1–5 years, mean age = 2.79) diagnosed with a variety of neuromotor/ developmental disorders/high-risk conditions. Inter-rater reliabilitywas examined on the following 11 items in the N5E2: (1) Retrieving a rolling ball, (2) Gait, (3) Toe-walking, (4) Asymmetries of posture and/or movement, (5) Age at unsupported walking, (6) Speaking in two-word understandable sentences, (7) Hypotonus, (8) Hypertonus, (9) Eye movement, (10) Vision problem, (11) Hearing problem. The items were administered to children by two pediatricians with different expertise and clinical experience, separately. Results The results showed that among the eleven items in the N5E2 examined, a high level of agreement (κ ≥ 0.60) was found on 4 items, and a moderate level of agreement (0.40 ≤ κ  r  = 0.84). Conclusions The results suggest the possibility that this brief screening tool could be feasible in settings where clinicians’ experience varies, based on its inter-rater reliabilityon individual items between the clinicians with different expertise and amount of clinical experiences.
