Fig 1.
Pose landmark [31] and calculated distance.
This figure shows the limbs’ distance (dash line, —) from the landmarks 15, 16, 27, and 28 to the midbody imaginary line.
Fig 2.
Pose landmark [31] and calculated area.
This figure shows the calculated area using the limbs pose landmarks (15, 16, 27, and 28) and the centre of the body coordinate which are listed as: (A) presenting the whole area; (B) presenting ❶ = the upper part area, and ❷ = the lower part area.

Flow chart of the study methodology.
MTM = movement toward midline.
Fig 4.
The distribution of MTM frequency among infants who showed MTM on the recording day.
This figure shows the MTM occurrence data that was observed based on infant age in days post-term age (PTA). MTM = movement toward midline.

Anthropometric data at birth according to the 2006 WHO Child Growth Standards: 0–6 months (weight and length) and 0–13 weeks (head circumference) [32] (N = 20).

Correlation between distances from the four limb landmarks to the midbody imaginary line and MTM observation.
Fig 5.
The difference between groups of videos that showed MTM and those that did not.
(A) The Lower MTM group represents infants showing foot-to-foot contact, foot-to-leg contact, and pedipulation. The comparison of whole area and upper- and lower-part areas between the groups of videos that showed MTM and those that did not are presented. (B) The Upper MTM group represents infants showing hand-to-hand, hand-to-face, hand-to-mouth, hand-to-trunk, hand-to-leg, manipulation, and fiddling. The comparison of whole area and upper- and lower-part areas between the groups of videos that showed MTM and those that did not are presented. (C) The Total MTM group represents infants showing all 10 items: foot-to-foot contact, foot-to-leg contact, hand-to-hand, hand-to-face, hand-to-mouth, hand-to-trunk, hand-to-leg, pedipulation, manipulation, and fiddling. The comparison of whole area and upper- and lower-part areas between groups of videos that showed MTM and those that did not are presented. MTM = movement toward midline, * p-value < 0.05. The sign of ′ represents the group of videos showing MTM and ≤ represents the group of videos not showing MTM.
