The aim of the study is to investigate the effectiveness of thoracic mobility versus lumbopelvic stabilization exercises combined with ankle strengthening exercises with resistive band on patients with chronic ankle instability in terms of lower extremity flexibility, proprioception and dynamic balance.The participants were divided into two group as Thoracic Mobility group (n=15) and Lumbopelvic Stability group (n=15). In addition their exercise programs (2 times/wk, 8 wk duration), both groups were given home exercise ankle strengthening exercises.(3 sets/ 10 reps, 3 times/wk.)

The aim of the study is to investigate the effectiveness of thoracic mobility versus lumbopelvic stabilization exercises combined with ankle strengthening exercises with resistive band on patients with chronic ankle instability in terms of lower extremity flexibility, proprioception and dynamic balance. The study were conducted in Noi Physio Pilates Studio in Istanbul between November 2022 - January 2023 during 8 weeks. 30 volunteers with chronic ankle instability were included according to Cumberland Ankle Instability Tool (CAIT). The cut off value for the CAIT test was determined as 27. Participants who received 27 or less than this value were included in the study. All participants were right dominant. Lower extremity flexibility was assessed with Active Straight Leg Raise Test, proprioception (hip, knee, ankle) was assessed with Joint Position Sense Test using electronic goniometer. Determined angles for joints; hip flexion angle as 75°, knee flexion angle as 50° and ankle dorsiflexion as 10° plantarflexion as 40°.Y Balance Test (anterior, posterolateral, posteromedial) was used for evaluating dynamic balance. 30 participants were divided into two groups as thoracic mobility and lumbopelvic stability group. Both groups were given ankle strengthening exercises (dorsiflexion, plantarflexion, inversion and eversion) with resistive band. Home exercises were performed 3 days a week for a total of 3 sets of 10 repetitions. Thoracic mobility group was given; thoracic extension on foam roller, sidelying thoracic rotation, quadruped thoracic rotation, squat with extension and rotation. Lumbopelvic stabilization group was prescribed; bridge with alternate leg, single leg bridge, four point kneeling with arm and leg extension, side plank on front arm with knee flexed (right, left), sitting on a Swiss Ball and hip flexion.Sessions took approximately 50 minutes and exercise program was planned twice a week for 8 weeks, 16 sessions total. Both groups were given ankle strengthening exercises (dorsiflexion, plantarflexion, inversion and eversion) with resistive band. Home exercises were performed 3 days a week for a total of 3 sets of 10 repetitions.

Participants were included to study accorcing to Informed Consent Form (ICF). Datas and informations were recorded.

8 week

Informed consent form was used for gathering demographic information from participants. Cumberland Ankle Instability Tool (CAIT) was used for assesing chronic ankle instability. Cut off value was determined as ≤27 points.
