Ankle Joint

Ankle Joint

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...

A 4-week balance training program significantly improved function and postural control in individuals with chronic ankle instability (CAI). Time-to-boundary measures were more sensitive than center of pressure measures for detecting improvements.

Area of Science:

Sports Medicine
Rehabilitation Science
Biomechanics

Background:

Chronic ankle instability (CAI) is a common condition affecting functional outcomes and postural control.
Effective interventions are needed to improve static and dynamic balance in individuals with CAI.

Purpose of the Study:

To evaluate the impact of a 4-week balance training program on static and dynamic postural control in individuals with CAI.
To assess changes in self-reported functional outcomes following the balance training program.

Main Methods:

A randomized controlled trial involving 31 young adults with CAI.
Intervention group received a 4-week supervised balance training program emphasizing dynamic stabilization.
Outcome measures included the Foot and Ankle Disability Index (FADI), time-to-boundary (TTB), center of pressure (COP), and Star Excursion Balance Test (SEBT).

Evaluating Postural Control and Lower-extremity Muscle Activation in Individuals with Chronic Ankle Instability

Evaluating Postural Control and Lower-extremity Muscle Activation in Individuals with Chronic Ankle Instability

Published on: September 18, 2020

Main Results:

The balance training group showed significant improvements in FADI scores and FADI Sport scores.
Significant enhancements were observed in time-to-boundary (TTB) measures with eyes closed and in specific reach directions of the SEBT.
Summary COP measures showed limited significant changes compared to TTB measures.

Conclusions:

Four weeks of balance training effectively improved self-reported function in individuals with CAI.
The program enhanced static postural control, as indicated by TTB measures, and dynamic postural control, as assessed by the SEBT.
TTB measures demonstrated greater sensitivity in detecting improvements in static postural control compared to summary COP measures.
