[Participants and Methods] This retrospective, observational study included 57 infants with no neurodevelopmental handicaps (average weight at birth 963.2 ± 298.2 g, gestational age 28.4 ± 3.1 weeks), who were transferred to the neonatal intensive care unit at a medical center in Japan between 2010 and 2014. The patients were classified into two groups based on weight at birth: 32 infants with birth weights <1,000 g (Group A) and 25 with birth weights between 1,000 and 1,499 g (Group B). Data on the ages at which bilateral hand use was attained (\"playing with both hands together\", \"transferring a toy between the two hands\", and \"grasping two toys, one in each hand\") were collected from the respective medical records and compared between the two groups.

[Results] Muscle mass and water content measurements demonstrated high reliability across all limb sites, with intraclass correlation coefficients ranging from 0.996 to 0.998. Phase angle measurements also showed high reliability for the limbs, with values ranging from 0.936-0.975; however, reliability was lower for the trunk, with a value of 0.854. The minimal detectable change values indicated that detecting differences in trunk phase angle required a larger change than that required for limb sites.

[Participants and Methods] Twenty healthy adults (14 males and six females) participated in this study. A VICON 3D motion-analysis device was used and the analysis used the medial longitudinal arch height model in addition to the full plug-in model. The medial longitudinal arch height, ankle joint internal plantar flexion moment, ankle joint angle, and movement of the center of gravity were measured. The focus was on running cycle synchrony and changes in the medial longitudinal arch height. A one-way analysis of variance for multiple comparisons was performed.

The medial longitudinal arch showed a reverse windlass phenomenon, with a minimum of 17.1 mm at an approximately 60% running cycle and then a spike-like phenomenon of 29.1 mm at a 98% running cycle.

Physical function assessments included motor paralysis, spasticity, pain (numerical rating scale [NRS]), shoulder range of motion (ROM), sensory impairments, and shoulder subluxation using the fingerbreadth palpation method. Ultrasound was used to measure the AGT distance and the thickness of the long head of the biceps tendon. [Results] A significant correlation was found between the AGT distance and subluxation, measured using the fingerbreadth palpation method, confirming its validity. The AGT distance was positively correlated with spasticity, tendon thickness, and NRS during movement but negatively correlated with motor paralysis and shoulder ROM. These findings suggest that an increased AGT distance may be associated with severity of subluxation, reduced motor function, and a higher pain level during movement.
