Abstract: Background/Objectives: Stroke patients generally have balance and gait dysfunction due to decreased range of motion (ROM) and muscle strength of the ankle joint. A therapist can apply a floss band to enhance ROM, pain control, jumping performance, strength, myofascial release, and recovery from fatigue. This study compared the immediate effects of floss band application on ankle ROM, balance, and gait ability in stroke patients.; Methods: This study randomized 40 chronic stroke patients to either the floss (n = 20) or sham (n = 20) band group. Outcome measures were ankle ROM, weight bearing lunge test (WBLT) performance, standing balance, and gait ability. Outcome measures were assessed at baseline and immediately after applying the floss or placebo band.
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 participants were instructed to perform low-intensity active exercise involving ankle DF and plantar flexion for 2 minutes after applying the floss band. Then, the floss band was removed and the patient was asked to walk lightly on level ground for about 1 minute to allow reperfusion to normalize blood flow.

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.

Behavioral: floss band
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 range of motion
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.
Time frame: 1 year
Weight-bearing lunge test
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 ability
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.
Time frame: 1 year
Gait ability
The APDM Mobility Lab™ Opal inertial sensor system (APDM) was used to assess gait based on the foot strike (FS) and toe-off (TO) angles. Data were collected from the sensor wirelessly at a sampling rate of 128 Hz and processed to quantify postural sway parameters. 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 at each ankle. Verbal instructions were given to ensure accuracy. The subject was told to stand still at the start line until the first long tone was heard, at which time they started walking at a comfortable natural pace. When a second tone was heard after 2 minutes, the participants were asked to stop walking. After practicing for 30 seconds to become familiar with the test, participants were asked to walk back and forth along a straight 10-meter corridor at their usual pace for 2 minutes without a walking assist.
