Different Pressure Tissue Flossing Combined With Exercise for Chronic Ankle Instability (CAI-FLOSS)

2026년 6월 21일 업데이트: Wei-yang Zhang, Chengdu Sport University

Effects of Different Tissue Flossing Pressures Combined With Exercise Training on Ankle Function in Patients With Chronic Ankle Instability: A Three-Arm Randomized Controlled Trial

This study will evaluate whether tissue flossing with different pressure levels, when combined with exercise training, improves ankle function in young adults with chronic ankle instability. Forty-eight participants will be randomly assigned to one of three groups: a control exercise group, a 150 mmHg tissue flossing plus exercise group, or a 200 mmHg tissue flossing plus exercise group. All groups will complete the same 6-week rehabilitation program, three times per week. Outcomes will be assessed at baseline and after the intervention, and long-term follow-up data will also be collected.

상세 설명

Chronic ankle instability is characterized by recurrent ankle sprains, a feeling of giving way, pain, swelling, reduced function, and impaired balance control. Exercise-based rehabilitation is a cornerstone of nonoperative management, but adjunctive strategies that may enhance recovery remain of interest.

Tissue flossing is a compression-based intervention in which an elastic band is wrapped around the target joint or limb segment during exercise. It may influence mobility, neuromuscular control, proprioception, and symptom perception. However, the optimal pressure level for long-term rehabilitation in chronic ankle instability remains unclear.

This single-center, assessor-blinded, three-arm parallel randomized controlled trial will be conducted at Chengdu Sport University. A total of 48 young adults with chronic ankle instability will be allocated in a 1:1:1 ratio to a control exercise group, a 150 mmHg tissue flossing plus exercise group, or a 200 mmHg tissue flossing plus exercise group. All participants will complete the same 6-week rehabilitation program, with 3 sessions per week and 18 sessions in total. The two tissue flossing groups will receive pressure-calibrated flossing during the main training phase, while the control group will perform the same exercises without compression.

The primary outcome will be the change in Foot and Ankle Ability Measure Activities of Daily Living score from baseline to 6 weeks. Secondary outcomes will include sport-related foot and ankle function, functional movement screening, ankle range of motion, ankle isometric strength, Biodex balance-related measures, pain, long-term follow-up outcomes, adherence, and adverse events.

무기와 개입

참가자 그룹 / 팔
개입 / 치료
활성 비교기: Control Exercise Training
Participants will complete a 6-week ankle rehabilitation exercise program, 3 sessions per week, without tissue flossing compression.
행동: Exercise Training
All groups will perform the same supervised ankle rehabilitation program for 6 weeks, 3 sessions per week, 18 sessions in total, approximately 30 minutes per session. The program will include warm-up, forward lunge ankle mobility training, resistance exercises for dorsiflexion, plantarflexion, inversion, and eversion using an elastic band, double-leg vertical jumping, single-leg balance training, and cool-down. From week 4 onward, the balance task will be progressed to eyes-closed single-leg stance.
실험적: 150 mmHg Tissue Flossing Plus Exercise Training
Participants will complete the same 6-week ankle rehabilitation exercise program as the control group, with tissue flossing applied to the affected ankle at 150 mmHg during the main training phase.
행동: Exercise Training
All groups will perform the same supervised ankle rehabilitation program for 6 weeks, 3 sessions per week, 18 sessions in total, approximately 30 minutes per session. The program will include warm-up, forward lunge ankle mobility training, resistance exercises for dorsiflexion, plantarflexion, inversion, and eversion using an elastic band, double-leg vertical jumping, single-leg balance training, and cool-down. From week 4 onward, the balance task will be progressed to eyes-closed single-leg stance.
장치: Tissue Flossing at 150 mmHg
During the main exercise phase, tissue flossing will be applied to the affected ankle using an elastic floss band calibrated with a pressure gauge to 150 mmHg. Wrapping will start distally over the dorsum of the foot and follow a figure-of-eight pattern covering the ankle joint region and extending to the distal lower leg. The floss band will be removed immediately after training. If numbness, severe pain, or pallor occur, the compression will be removed immediately.
실험적: 200 mmHg Tissue Flossing Plus Exercise Training
Participants will complete the same 6-week ankle rehabilitation exercise program as the control group, with tissue flossing applied to the affected ankle at 200 mmHg during the main training phase.
