Summary
Children with lower limb deficiency (LLD) showed poorer verbal understanding of body parts, including arms and feet, compared to typically developing peers. This impacts their overall body perception and knowledge.
Area of Science:
- Developmental Psychology
- Neuroscience
- Pediatric Orthopedics
Background:
- Understanding body parts is crucial for motor function development.
- Children with congenital lower limb deficiency (LLD) may have altered body perception.
- Research on body schema in children with LLD is limited.
Purpose of the Study:
- To investigate body perception in children with congenital LLD.
- To compare body knowledge between children with and without LLD.
- To assess understanding of body part names and locations.
Main Methods:
- Included 6 children with congenital LLD and 14 controls (ages 5-12).
- Utilized self-portrait drawing and verbal questioning (production and comprehension tests).
- Assessed knowledge of body parts including trunk, limbs, hands, and feet.
Main Results:
- No significant differences in self-portrait drawings between groups.
- Children with LLD demonstrated lower accuracy in verbal identification of body parts.
- Deficits were noted for the trunk, upper limbs, arms, hands, and feet.
Conclusions:
- Children with LLD exhibit diminished lexical-semantic body knowledge.
- This impacts their understanding of upper limbs and feet compared to controls.
- Findings highlight potential challenges in body representation for children with LLD.

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...
