Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims at investigating the validity and reliability of a smartphone application "MyAnkle: in assessing the balance component of postural control in patients with chronic ankle instability (CAI).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Lateral ankle sprain (LAS) is a common injury in athletic and regular activities; with an incidence of 7 per 1000 exposure. After LAS, residual symptoms may persist leading to chronic ankle instability (CAI). This instability is believed to arise from dysfunctional postural control, defective proprioception, weak muscles, or reduced ankle range of motion (ROM).Thus, assessment of postural control is essential for proper clinical decision-making and treatment selection.

With advances in technology, smartphone has been introduced as an assessment tool for the musculoskeletal system. For example, it was used in assessment of ROM and mobility in stroke patients and frail elderly conditions. Further, it was used to assess balance and falling risk in those population. In addition, it was used to assess balance in healthy and participants with chronic ankle sprain. These studies proved that smartphone is a valid and reliable tool that is light in weight and inexpensive. Yet, these studies have some methodological concerns. For example, the application was not validated against gold standard or was validated only in healthy volunteers rather than in patients with musculoskeletal dysfunction. Further, a few of these studies did not establish the application discriminative validity between patients and healthy controls. Thus, this study will try to answer the following question: "Is smartphone application a valid and reliable tool to assess balance in patients with CAI compared to gold standards?

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients with CAI

Patients referred with a confirmed diagnosis of CAI, with a Cumberland Ankle Instability tool score lower than 27 points. Patients should have had a recurrent sprain within the previous year.

Patients will have their balance assessed using the "Myankle" smartphone application simultaneously with Biodex balance system assessment.

Smartphone "MyAnkle" balance application

Intervention Type DIAGNOSTIC_TEST

Balance will be assessed simultaneously using "MyAnkle" application and the Biodex balance system. The smartphone will be fixed to the middle of the shin with an armband. Participants will assume a single leg stance on each side under two conditions: eyes opened and closed. Testing will be done at three levels of difficulty; least difficult (level 8), moderate (level 6) and severe difficult (level 4). A conditioning trial for each level will be given for 30 seconds. Further, a 2-minute rest between tests will be given. During the testing, participants should not touch the ground or stance limb by other limb nor to grasp the handrail. Participants will repeat the same testing in two separate sessions, with one-week interval in between.

Healthy participants

Healthy participants who are not complaining of pain and have not be exposed to trauma, injury or undergone surgery for the lower quadrant of the body.

Participants will have their balance assessed using the "MyAnkle" smartphone application simultaneously with Biodex balance system assessment.
