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...

Summary

This summary is machine-generated.

Athletes with functional ankle instability (FAI) show significant deficits in most functional performance tests compared to healthy individuals. These tests can help identify FAI, especially in cases with giving way, but sagittal plane tests are less effective.

Background:

Functional ankle instability (FAI) is a common condition in athletes, often leading to recurrent ankle sprains and impaired joint function.
Identifying objective measures to assess functional deficits in athletes with FAI is crucial for effective rehabilitation and return-to-sport protocols.

Purpose of the Study:

To compare functional performance between athletes with FAI and healthy athletes using a battery of functional performance tests (FPTs).
To evaluate the efficacy of various FPTs in discriminating between athletes with and without FAI, including subgroups with and without giving way.

Main Methods:

A case-control study involving 62 athletes, divided into an FAI group (n=31) and a Non-FAI group (n=31).
The FAI group was further stratified into FAI with giving way (FAI-GW) and FAI with no giving way (FAI-NGW) subgroups.
Functional performance was assessed using the single-limb hopping, figure-of-8 hop, side-hop, single-limb hurdle, square hop, and single hop tests.

Main Results:

Significant performance deficits (P<0.05) were found in the FAI group compared to the Non-FAI group across all tested FPTs, except for the single hop test.
Greater functional deficits were observed in the FAI-GW subgroup compared to both the FAI-NGW and Non-FAI groups.
The involved limb in the FAI-GW group demonstrated significantly poorer performance than the contralateral limb for most FPTs.

Conclusions:

Most functional performance tests effectively identify deficits in athletes with FAI, with greater sensitivity in those experiencing giving way.
The single hop test and tests focusing on sagittal plane movements appear less effective in discriminating individuals with FAI.
These findings support the use of specific FPTs for diagnosing FAI and guiding rehabilitation, while highlighting limitations for certain movement patterns.
