Ankle Joint01:10

Ankle Joint

3.8K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Summary

Children show greater ankle movement variability than young adults, especially with high-gain visual feedback. This increased variability in children is linked to their movement control and tibialis anterior muscle activity, suggesting immature motor systems.

Area of Science:

  • Neuroscience
  • Motor Control
  • Developmental Biology

Background:

  • Visual feedback plays a crucial role in refining motor control.
  • Understanding age-related differences in visual-motor integration is essential for developmental research.
  • Children's motor skills are still developing, potentially impacting their reliance on and processing of visual cues.

Purpose of the Study:

  • To compare the effects of low- and high-gain visual feedback on ankle movement variability and muscle activation in children and young adults.
  • To investigate age-specific responses to amplified visual feedback during a motor task.
  • To explore the relationship between movement variability, muscle activity, and visual feedback gain in different age groups.

Main Methods:

  • Participants (children and young adults) performed ankle plantar/dorsiflexion movements to trace a sinusoidal target.
  • Two visual feedback gains (low: 0.66°, high: 4.68°) were applied during the task.
  • Ankle movement variability and tibialis anterior (TA) muscle electromyography (EMG) were recorded and analyzed across specific frequency bands.

Main Results:

  • Children exhibited significantly greater ankle movement variability compared to young adults.
  • High-gain visual feedback exacerbated movement variability in children more than in young adults.
  • Increased low-frequency (0-0.3 Hz) movement variability in children was associated with greater low-frequency power in their TA muscle EMG activity.

Conclusions:

  • Children's greater movement variability under high-gain visual feedback suggests less effective use of visual information and potential immaturity in cortico-motor systems.
  • Age-related differences in visual feedback processing may contribute to distinct motor control strategies.
  • Findings highlight the impact of visual feedback gain on motor variability and muscle activation in developing individuals.
