About this trial

This is an interventional basic science trial for Chronic Instability of Joint

Eligibility Criteria

18 Years - 40 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • history of at least one significant ankle sprain which occurred at least 12 months prior to enrolment in the study and was diagnosed by a physician or a physical therapist using clinical examination classifications described by Malliaropoulos et al
  • history of at least two episodes of 'giving way', and feelings of ankle joint instability in the previously injured ankle joint of 1 year post-initial sprain
  • the most recent injury occurred more than 6 weeks prior to the study enrolment
  • the ability to apply full weight bearing on the injured lower extremity with no more than mild discomfort

Exclusion Criteria:

  • evidence of a concomitant injury (such as a bony injury or significant muscular/tendon injury)
  • previous ankle surgery
  • other pathological conditions or surgical procedures in lower extremity
  • neurological/vestibular or any other balance disorder.

The control group included healthy participants with no current or previous conditions that could affect proprioception.

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Experimental

Arm Label

Chronic Ankle Instability

Healthy controls

Arm Description

Soldiers who suffer from chronic ankle instability who had a first major ankle sprain one year or more ago, and did not sustained any major ankle sprain in the last two months, will go through Gait analysis intervention.

Healthy soldiers who are not suffering from chronic ankle instability, will go through Gait analysis intervention.

Outcomes

Primary Outcome Measures

Stride time variability
Coefficient of variance of the stride time, measured in % by the OPTOGait system
Stride length variability
Coefficient of variance of the stride length, measured in % by the OPTOGait system

Secondary Outcome Measures

Dual task general score
Participants will be asked to count backward, reducing 7 at a time, starting at different 3 digits number. The outcome measure is a calculation of the number of total answers multiple by (number of correct answers - number of wrong answers).

5. Study Description

Brief Summary
Case-control study to evaluate gait parameters during different conditions between patients who suffer from chronic ankle instability and healthy individuals.
Detailed Description
This case-control study will compare the different gait parameters such as stride time and stride length variability in different gait conditions (e.g., normal speed, normal speed with dual task, fast speed and fast speed with dual task) between healthy individuals and patients who suffer from chronic ankle instability. the measurements will be collected using the OPTOGait system installed on a treadmill.
