“…Inter‐assessor reliability of the original version of the MOS has previously shown to be high when used in different populations (intraclass correlation coefficient (ICC): 0.80–0.98, 13,22,23 κw: 0.87–0.91) 14 . A few studies have also presented inter‐assessor reliability data for the total MOS‐R (ICC: 0.86–0.96) 22,24,25 . Details regarding reliability across different subcategories, however, and whether its use at different age‐spans influences assessor agreement are less known.…”

Aim:To assess the inter-assessor reliability of the Motor Optimality Score-Revised (MOS-R) when used in infants at elevated likelihood for adverse neurological outcome.Methods: MOS-R were assessed in three groups of infants by two assessors/cohort.Infants were recruited from longitudinal projects in Sweden (infants born extremely preterm), India (infants born in low-resource communities) and the USA (infants prenatally exposed to SARS-CoV-2). Intraclass correlation coefficients (ICC) and kappa (κw) were applied. ICC of MOS-R subcategories and total scores were presented for cohorts together and separately and for age-spans: 9-12, 13-16 and 17-25-weeks post-term age.Results: 252 infants were included (born extremely preterm n = 97, born in lowresource communities n = 97, prenatally SARS-CoV-2 exposed n = 58). Reliability of the total MOS-R was almost perfect (ICC: 0.98-0.99) for all cohorts, together and separately. Similar result was found for age-spans

“…The movement optimality scale [ 2 , 10 ] was established and revised based on the GMA, with scores ranging from 5 to 28. A decrease in the score may indicate a higher risk of motor or cognitive impairment [ 11 , 12 ]. Although this assessment result is predominantly based on the presence of FMs, it also considers various concurrent postural and movement patterns observed alongside GMs, which may affect the overall score.…”

“…Although this assessment result is predominantly based on the presence of FMs, it also considers various concurrent postural and movement patterns observed alongside GMs, which may affect the overall score. These encompass the alignment of the head, body, and limbs, as well as asymmetric tonic neck posture (ATNP) and limb movements, such as movement toward the midline (MTM) (foot-to-foot [FF], fiddling, hand-to-hand [HH], and hand-to-mouth [HM] contact) [ 2 , 12 , 13 ]. A study evaluating concurrent motor and postural patterns with GMs for the early diagnosis of CP found that MTM in both the upper and lower limbs could be considered at fidgety age, following monotonous and stereotyped limb movements [ 9 ].…”

In infants, spontaneous movement towards the midline (MTM) indicates the initiation of anti-gravity ability development. Markerless 2D pose estimation is a cost-effective, time-efficient, and quantifiable alternative to movement assessment. We aimed to establish correlations between pose estimation features and MTM in early-age infants. Ninety-four infant videos were analysed to calculate the percentage and rate of MTM occurrence. 2D Pose estimation processed the videos and determined the distances and areas using wrist and ankle landmark coordinates. We collected data using video recordings from 20 infants aged 8–16 weeks post-term age. Correlations between MTM observations and distance values were evaluated. Differences in areas between groups of videos showing MTM and no MTM in the total, lower-limb, and upper-limb categories were examined. MTM observations revealed common occurrences of hand-to-trunk and foot-to-foot movements. Weak correlations were noted between limb distances to the midbody imaginary line and MTM occurrence values. Lower MTM showed significant differences in the lower part (p = 0.003) and whole area (p = 0.001). Video recording by parents or guardians could extract features using 2D pose estimation, assisting in the early identification of MTM in infants. Further research is required to assess a larger sample size with the diversity of MTM motor behaviour, and later developmental skills, and collect data from at-risk infants.

“…The Prechtl general movements assessment (GMA) has proven to be an efficient and reliable diagnostic tool for detecting cerebral palsy within the first few months of human life 4 . The significance of general movements as a biomarker for divergent early brain development, and their long-term relevance for cognitive, speech-language, and motor development have been widely acknowledged 5 – 8 .…”

Background Aiming at objective early detection of neuromotor disorders such as cerebral palsy, we propose an innovative non-intrusive approach using a pressure sensing device to classify infant general movements. Here we differentiate typical general movement patterns of the “fidgety period” (fidgety movements) vs. the “pre-fidgety period” (writhing movements). Methods Participants (N = 45) were sampled from a typically-developing infant cohort. Multi-modal sensor data, including pressure data from a pressure sensing mat with 1024 sensors, were prospectively recorded for each infant in seven succeeding laboratory sessions in biweekly intervals from 4 to 16 weeks of post-term age. 1776 pressure data snippets, each 5 s long, from the two targeted age periods were taken for movement classification. Each snippet was pre-annotated based on corresponding synchronised video data by human assessors as either fidgety present or absent. Multiple neural network architectures were tested to distinguish the fidgety present vs. fidgety absent classes, including support vector machines, feed-forward networks, convolutional neural networks, and long short-term memory networks. Results Here we show that the convolution neural network achieved the highest average classification accuracy (81.4%). By comparing the pros and cons of other methods aiming at automated general movement assessment to the pressure sensing approach, we infer that the proposed approach has a high potential for clinical applications. Conclusions We conclude that the pressure sensing approach has great potential for efficient large-scale motion data acquisition and sharing. This will in return enable improvement of the approach that may prove scalable for daily clinical application for evaluating infant neuromotor functions.
