What is the overall direction of motor development described in the PowerPoint?
The name of the measure, patient’s score, cut score if available, and interpretation related to discharge planning.
What does “stability before mobility” mean in motor development?
A: A child must first develop postural stability in a position before they can move efficiently within or out of that position.
Why is postural stability critical for movement development?
A: Stability allows effective weight bearing and weight shifting, which are necessary for controlled movement.
What is the relationship between weight shifting and movement control?
A: Controlled movement requires weight shifts, where one body part stabilizes while another is unweighted enough to move.
How does weight bearing contribute to motor development?
A: Weight bearing experiences assist in the development of postural stability and control.
What does the PowerPoint mean by “mass patterns”?
A: Early movement patterns where large portions of the body move together rather than independently.
What is dissociation and why is it important?
A: Dissociation is the ability to separate movement in one body part from another, allowing refined and efficient movement.
How does dissociation emerge over time?
A: Development progresses from total body responses to localized, segmental control.
What role does rotation play in movement development?
A: Rotation requires balanced flexion and extension and dissociation between body segments, and it supports efficient transitions and mobility.
Why is symmetry important early in development?
A: Symmetry supports midline orientation and balanced muscle activity, which are foundations for later controlled asymmetry.
What is controlled asymmetry?
A: The ability to move asymmetrically while maintaining postural control and stability.
How does movement quality change as children develop?
A: Movements become smoother, more coordinated, more adaptable, and better timed.
What does the PowerPoint emphasize about variability in movement?
A: Typical development includes variability, variety, and frequent spontaneous movement.
Why is variability considered a positive sign?
A: It shows the child is exploring multiple movement strategies and adapting to the environment.
What does lack of variability suggest to a PT?
A: Possible atypical development, poor adaptability, or underlying control issues.
What are PTs observing when they assess motor development?
A: Posture, alignment, movement quality, weight shifts, symmetry versus asymmetry, and adaptability.
Why is observing posture important?
A: Posture reflects the child’s ability to control their body against gravity and organize movement.
What does “quality of movement” mean in this course?
A: How a movement is performed, not just whether the movement occurs.
Why are milestones considered flexible rather than rigid?
.
A: Development is variable and adaptive, and milestones represent progress toward independence, not fixed ages
What is meant by “rate-limiting factors” in motor development?
A: Certain factors like strength or postural control can limit expression of movement even if the nervous system is capable.
How do PTs use knowledge of rate-limiting factors clinically?
A: By modifying the environment or providing support to reveal the child’s movement potential.
How does stability change as development progresses?
A: Stability shifts from reliance on external support to internal postural control that supports movement.
What happens when stability is insufficient?
A: Children may fix or limit degrees of freedom, reducing movement options.
What does fixing degrees of freedom look like?
A: Stiff, restricted movement patterns with limited adaptability
