Virtual reality versus Biodex Training in Adolescent 
Athletes with  Chronic Ankle Instability 
 
 
PURPOSE:  
 
This study aimed to assess the efficacy of virtual reality versus biodex 
training in adolescent athletes with chronic ankle instability. 
 
BACKGROUND: 
Ankle instability results from repetitive ankle sprains are common injuries in active 
young people. Most of these injuries recovery quickly on their own, do not require 
imaging, and do better with early motion and rehabilitation. High ankle sprains and 
fractures are much less common but more serious. They may require imaging and 
more treatment. 
Phases of rehabilitation for ankle sprain
 
Phase I treatment involves resting and protecting the ankle to permit healing, to 
prevent further injury, and to control pain and swelling. 
 
Phase II treatment begins once pain and swelling have subsided to the point where the 
athlete can comfortably bear weight and walk from place to place. 
 
Virtual reality (VR) is a simulated experience that can be similar to or completely 
different from the real world. Applications of virtual reality can include entertainment 
(i.e. video games) and educational purposes (i.e. medical or military training). Other, 
distinct types of VR style technology include augmented reality and mixed reality. 
 
HYPOTHESES: 
 
H0 there is no significance difference between virtual reality versus 
biodex training in adolescent athletes with chronic ankle instability. 
 
H1 there is a significance difference between virtual reality versus biodex 
training in adolescent athletes with chronic ankle instability. 
 
RESEARCH QUESTION: 
 
Is there is no significance difference between virtual reality versus biodex 
training in adolescent athletes with chronic ankle instability? 
 
 
 

Aim of the study: 
To determine the effect of to assess difference between virtual reality 
versus biodex training in adolescent athletes with chronic ankle 
instability. 
Inclusion criteria: 
1. Children will have sustained lateral ankle sprain (grade II). 
2. Their age was ranging from 12-16 years 
3. Children participated in this study only males. 
4. They will able to follow the verbal commands or instructions during testing. 
Exclusion criteria:
    
 
  
1. Children with 1,2 grade of ankle sprain 
2. Children with deformity in foot 
3. Children with back problems. 
4. Children with balance affection. 
 
Methods for assessment: 
 Balance assessment 
o Over All Stability Index  
o Antero-Posterior Stability Index  
o Medio-Lateral Stability Index (MLSI) 
Methods for treatment: 
Sixty patient with muscular dystrophy were enrolled in this study and 
were assessed for eligibility.  
Group (A) received the traditional physical therapy program. 
 
Group (B) received the traditional physical therapy program in addition 
to virtual reality. 
Group (B) received the traditional physical therapy program in addition 
to biodex balance training. 
All patients will received  sessions three times / weak for three successful 
months. Pulmonary function test were used to assess pulmonary functions 
pre and post intervention. All patients were assisted before and after three 
months of intervention.
