简要总结
Ankle sprains are one of the most common sports injuries. In some people, they can lead to chronic ankle problems that affect daily life and sports performance. In this study, we want to see if combining neuromuscular electrical stimulation (NMES) with proprioceptive neuromuscular facilitation (PNF) can help improve these problems. We plan to recruit 60 participants, with 30 in the experimental group and 30 in the control group. The experimental group will receive PNF stretching with NMES, while the control group will only do PNF stretching. Both groups will have training three times a week for four weeks (12 sessions in total). We will test participants before and after the program, looking at pain, balance, range of motion, proprioception, strength, joint mobility, and functional limitations. We expect that 12 sessions will help improve chronic ankle problems, and that NMES combined with PNF will be more effective than PNF alone.

结局指标
主要结局
Star Excursion Balance Test, SEBT
时间窗: 1. Baseline (Day 1, prior to intervention) 2. Post-intervention (after 12 sessions, Week 4)
Balance ability will be assessed using the Star Excursion Balance Test (SEBT). Participants stand barefoot at the center of a grid with eight lines extending at 45° angles. They are instructed to reach with the distal part of the foot to touch the farthest point along each line while maintaining a standing position. The examiner recorded the reached distance in centimeters, measured from the center of the grid to the point touched by the participant's big toe.
Proprioception - ankle dorsiflexion (degrees)
时间窗: 1. Baseline (Day 1, prior to intervention) 2. Post-intervention (after 12 sessions, Week 4)
Proprioception of the affected ankle will be measured using the Micro FET3 inclinometer. The examiner moves the foot to a target angle (hold for 10 seconds), and then returned to the starting position. Participants then actively reproduces the angle. The difference between the target and reproduced angles represented proprioceptive accuracy.
Proprioception - ankle plantarflexion (degrees)
时间窗: 1. Baseline (Day 1, prior to intervention) 2. Post-intervention (after 12 sessions, Week 4)
Proprioception of the affected ankle will be measured using the Micro FET3 inclinometer. The examiner moves the foot to a target angle (hold for 10 seconds), and then returned to the starting position. Participants then actively reproduces the angle. The difference between the target and reproduced angles represented proprioceptive accuracy.
Muscle strength - ankle dorsiflexors (kg)
时间窗: 1. Baseline (Day 1, prior to intervention) 2. Post-intervention (after 12 sessions, Week 4)
A dynamometer (Micro FET3) will be placed on the dorsal surfaces of the metatarsals to measure strength of dorsiflexors.
Muscle strength - ankle plantarflexors (kg)
时间窗: 1. Baseline (Day 1, prior to intervention) 2. Post-intervention (after 12 sessions, Week 4)
A dynamometer (Micro FET3) will be placed on the plantar surfaces of the metatarsals to measure strength of plantarflexors.
Range of motion - Ankle dorsiflexion (degrees)
时间窗: 1. Baseline (Day 1, prior to intervention) 2. Post-intervention (after 12 sessions, Week 4)
The axis of the goniometer was placed at the lateral malleolus, the stationary arm aligned with the lateral fibula, and the moving arm aligned with the fifth metatarsal. Participants will be instructed to actively move the ankle from 0° starting position to maximal dorsiflexion.
