Chronic instability is a common condition in sports and there are many treatment methods and rehabilitation protocols available which are used according to extent of injury. The purpose of this study is to find out the effects of close kinetic chain exercises and open kinetic chain exercises and to find out which technique is more efficient for treating ankle instability, pain, and imbalance in athletes with chronic ankle instability. This study will help physical therapists and medical team to enhance the rehabilitation process.~The study would be randomized clinical trial conducted at Pakistan Sports board Lahore in which convenient random sampling technique would be used. This study will include total 15 participants and for this purpose Open Epi tool would be used as a sample size calculation. Participants falling in this category would be recruited into the study after inclusion and exclusion criteria. The Cumberland ankle instability tool will be used as a tool for pre and post assessment of athletes. In this study we will divide population into two groups. Group A will receive open chain kinetic exercises and Group B will be treated with Closed chain kinetic exercises. Data will be analyzed through SPSS 25 version.
The goal of this Randomized clinical trial is to find the effects of open versus closed kinetic chain exercises on ankle joint function in athletes with chronic ankle instability. The main question it aims to answer is:~• To compare the effects of open versus closed kinetic chain exercises on pain, instability and balance in athletes with chronic ankle instability.~Participants will be a given consent form and after subjects read and signed the informed consent and completed the self-reported questionnaires designed to identify subjects with CHRONIC ANKLE INSTABILITY, subjects completed baseline measurements that included Foot and Ankle Ability Measure (FAAM)-Sport Subscale, Reach distance, and SEBT. Participant will be divided into two groups (Group A and Group B) through lottery method. Group A will receive open kinetic exercises 3times a week for 3-4 weeks. Group B will receive close kinetic exercises 3 times a week for 3-4 weeks.
