About

The study is, in accordance with current legislation, definable as a single-center interventional study with evaluations carried out at a single timeframe.

The objective of the study is to compare jumping performance between subjects with ankle instability and healthy volunteer subjects.

In particular, the primary objective is to verify the difference in the monopodalic CMJ value of the diseased limb of subjects with ankle instability compared to the control group at time 0.

The population is made up of patients suffering from ankle instability and a control group of healthy volunteers, divided as follows:

25 subjects GROUP A: Study group: patients suffering from ankle instability

25 subjects GROUP B: control group: healthy voluntary subjects not affected by ankle pathology

Full description

Ankle sprains are one of the most common injuries during sports activity which often results in chronic instability of the ankle, characterized by a feeling of sagging more or less associated with pain with impairment of sports activity.

Numerous authors have suggested that there is altered peripheral neuromuscular control in patients with ankle instability with limitations related to proprioception, neuromuscular control, or strength, leading to deficits not only of the ankle joint but of the entire inferior kinetic chain Jumping is a simple gesture, present in almost every sporting activity, and its evaluation has proven to be a reliable parameter in terms of partisan capacity.

Patients suffering from chronic ankle instability symptomatic of recurrent subjective and objective instability will be considered. Patients will be compared to a control group of healthy volunteer subjects.
