Summary

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.

  • Ankle Instability

Interventions

BEHAVIORAL

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.

DEVICE

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.

DEVICE

Tissue Flossing at 200 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 200 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.
