Developmental transformations of spontaneous movements in early infancy
Early Human Development
|December 1, 1986
Summary
General movements in infants transform from writhing to fidgety movements around two months. This developmental shift may be linked to the calibration of the proprioceptive system.
Area of Science:
- Neuroscience
- Developmental Biology
- Motor Control
Background:
- Infant motor development involves significant neural transformations.
- General movements in infants change in character during early development.
Purpose of the Study:
- To describe the transition of general movements in infants.
- To investigate the characteristics of 'fidgety' movements.
- To explore potential functions of fidgety movements in proprioceptive system calibration.
Main Methods:
- Longitudinal observation of general movements in infants.
- Qualitative analysis of movement characteristics.
Main Results:
- General movements change from a writhing to a 'fidgety' form around the second postnatal month.
- The onset and duration of fidgety movements show individual variability.
- 'Fidgety' movements represent a transient developmental phase.
Conclusions:
- 'Fidgety' movements are a key indicator of neural maturation.
- The emergence of fidgety movements may signify the calibration of the proprioceptive system.
- Further research is needed to confirm the role of fidgety movements in sensory-motor development.

00:51Anatomical Movements
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...

01:18Hierarchy of Motor Control
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
01:22Somatic Spinal Reflexes
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:14Piaget's Stage 1 of Cognitive Development
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

01:12Alterations in Muscle Tone ll
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
