Comparison of fetal and maternal tissue elasticity between euploid and aneuploid pregnancies by shear wave elastography.

Aim: B-mode ultrasonography utilized for fetal screening of common trisomies is referred to as a genetic sonogram and includes determining major abnormalities and soft markers such as hypoplastic nasal bone and increased thickness of the nuchal fold. Elastography is a novel ultrasound technique giving information about tissue stiffness used for diagnosing cancer, transplant rejection, and organ fibrosis. This study aimed to determine via shear wave elastography (SWE) whether euploid and aneuploid fetal soft marker tissues vary in stiffness.

Developmental differences of kinematic and muscular activation patterns in instep soccer kick.

Kinematic and neuromuscular activity differences amongst soccer players in different age groups were examined in this study. Thirty male soccer players evenly divided into three age groups (Group 1: age 12-13; Group 2: age 14-15; Group 3: age 16-17) were asked to perform instep kicks towards a target 11 m away. Their anthropometrics, instep kick kinematics, resultant ball velocities, both legs isokinetic strength, and electromyography (EMG) during kicking were compared amongst the three age groups.

Methods: The study involved 15 patients with SLIL injury (instability group) and 11 healthy participants (control group).

Combined Effects of Mirror Therapy and Exercises on the Upper Extremities in Children with Unilateral Cerebral Palsy: A Randomized Controlled Trial.

: This study investigated the combined effects of mirror therapy involving power and strength exercises of the upper extremities in children with Unilateral Spastic Cerebral Palsy (USCP).: Thirty children were included in either an experimental group or a control group. All participants were evaluated with the Quality of Upper Extremity Skill Test (QUEST), Canadian Occupational Performance Measure (COPM), and a handheld dynamometer to measure isometric muscle strength.
