The floss band intervention used the standard floss band technique, wrapping a floss band (lime green Sanctband Comprefloss™, 2" × 3.5 m; PENTEL, Shah Alam, Malaysia) made of natural rubber tightly around the ankle on the affected side. It was started at the fifth metatarsal and wrapped horizontally around the metatarsals twice, in a figure eight to the medial malleolus, over the Achilles tendon and the lateral malleolus three times, and around the medial malleolus again, before being passed twice from the medial mal-leolus over the Achilles tendon to the lateral malleolus, forming an end knot

The wrap used in the sham group lacked the elasticity of a floss band; the ankle was wrapped in the same manner, but loosely to facilitate blood circulation. Similarly, the participants were instructed to perform low-intensity active exercise involving ankle DF and plantar flexion for 2 minutes after applying the sham floss band. Finally, the sham floss band was removed, and the patient was asked to walk lightly on level ground for about 1 minute under the same conditions as in the floss band group.

Ankle passive ROM was measured using a universal goniometer in a non-weight bearing position. Subjects were prone with the knee joint at 90° . The ankle joint was set at 0° of eversion and inversion. The goniometer axis was placed beneath the lateral malleolus, and the stationary arm was positioned parallel to the fibula. The movable arm was positioned parallel to the fifth metatarsal, with the ankle in a neutral position. The measurement was repeated three times, and the average value was calculated. DF and PF measured angle.

The WBLT was performed to assess DF in a functional ankle joint. A measuring tape was placed horizontally on the floor perpendicular to a wall. The participants placed their affected-side foot on the tape with their big toe contacting the wall, and were instructed to touch the wall with the knee on the affected side. While maintaining this position, they were instructed to perform lunges by bending their knee, aiming for contact between their knee and the wall while keeping their heel firmly fixed on the floor. Once they were able to maintain knee and heel contact, the affected side foot was moved away from the wall, and they repeated the lunge test. The test was performed with 1-cm increases until knee and heel contact were no longer maintained. The maximum lunge distance was the far-thest distance from the wall to the big toe with the foot staying on the floor (without heel lifting) when the knee touched the wall. WBLT measured distance in centimeters.

Static balance was assessed using the APDM Mobility Lab™ Opal inertial sensor system (APDM, Portland, OR, USA). The test was conducted in a quiet treatment room. During the test, participants were barefoot and wore three Opal inertial sensors: one over their clothing at the level of the fifth lumbar vertebra and one on each ankle. Each subject was instructed to maintain their balance as stably as possible in a barefoot standing po-sition (10 cm between heels, toe-out of 5°) for 30 seconds. The test was repeated three times at 30-second intervals. The static balance outcome measure was the postural sway area (cm/s2). The signal was sampled, processed automatically, and streamed to a laptop using Mobility Lab™ software (Mobility Lab, Arlington, VA, USA). Balance measured sway range in millimeters squared.
