Ankle Joint01:10

Ankle Joint

1.8K
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...

Area of Science:

  • Biomechanics
  • Motor Control
  • Sports Medicine

Background:

  • Chronic ankle instability (CAI) results from recurrent ankle sprains, affecting approximately 70% of individuals with a history of lateral ankle sprains.
  • Potential contributing factors to CAI include proprioceptive deficits, impaired neuromuscular control, and compromised balance.
  • Understanding postural control is crucial for managing CAI and preventing further injury.

Purpose of the Study:

  • To compare postural control between individuals with CAI and healthy controls.
  • To analyze center of pressure (CoP) displacement using linear and nonlinear variables.
  • To assess postural control on both stable and unstable surfaces during a one-leg stance.

Main Methods:

  • 16 individuals with CAI and 20 healthy controls performed a 60-second single-leg stance on stable and unstable surfaces.
  • Force plate data were collected to measure CoP displacement, amplitude, and velocity (linear variables).
  • Nonlinear analysis included approximate entropy, sample entropy, correlation dimension, and Lyapunov exponent.

Main Results:

  • No significant differences in linear CoP variables were observed between groups on a stable surface.
  • The correlation dimension of mediolateral CoP displacement was significantly lower in the CAI group on the stable surface (p < 0.05).
  • No significant differences were found between groups for any variable on the unstable surface.

Conclusions:

  • The correlation dimension of CoP displacement during a single-leg stance on a stable surface is a key differentiator between individuals with and without CAI.
  • Lower correlation dimension values in the CAI group suggest impaired adaptability of their balance control system.
  • Further research is needed to fully elucidate the balance control mechanisms in individuals with CAI.
