Movement Combined with Weight-Shifting Mobilisation: A non-elastic band is secured between the patient's distal leg and the therapist's waist. Mobilisation begins with the patient standing in a comfortable upright position. The therapist applies a continuous posteroanterior gliding force to the tibia via the band by shifting their weight backwards. This technique functionally mimics the posterior glide mechanism of the talus. The participant is asked to perform a slow dorsiflexion to the end of the range of motion. During this, the therapist maintains the posterior glide stimulus on the talus. Once the end point is reached, the glide force is maintained for 10 seconds. One set of 10 repetitions of mobilisation is performed.

- Movement Combined with Mobilisation Without Weight-bearing The ankle is stabilised using a non-elastic band, and the therapist applies a posterior glide to the talus. During the posterior glide, the foot is supported by the forearm or leg.

Both mobilisation techniques and positions were explained to the participants; however, although the therapist positioned the ankle in the glide position, no sliding movement was performed, and the ankle was held in that position for 10 seconds.

Posterior talar glide mobilisation and dorsiflexion measurements were performed on both the affected and unaffected ankles. All measurements will be repeated three times-once before and three times after treatment-and the average values will be recorded.

- Movement Combined with Mobilisation Without Weight Shifting The participant lies supine with the tibia in contact with the treatment table, whilst the foot and ankle are left free at the edge of the table. The ankle is stabilised with a non-elastic band, and the therapist applies posterior glide to the talus.

The WBLT is a valid and reliable clinical measurement method widely used to identify dorsiflexion restrictions, particularly in individuals with chronic ankle instability, and to monitor changes occurring during the rehabilitation process. Its concurrent validity has been demonstrated in the literature using both angular and distance-based measurement methods. During measurement, the maximum lunge distance between the big toe and the wall will be recorded in centimetres using a standard tape measure fixed to the floor. Participants will undergo bilateral assessment during the test. Participants will be asked to touch the wall with their knees without lifting their heels off the ground. A vertical reference line on the floor will be used to minimise subtalar joint compensation and ensure measurement standardisation. The contralateral limb will be positioned comfortably behind the tested limb, and participants will be permitted to place their hands on the wall for balance.

The test is a valid and reliable assessment method widely used in clinical and research settings to measure an individual's walking speed over a short distance. The test will be conducted on a flat, non-slip surface. The total walking distance will be set at 14 metres; the first 2 metres will be designated as an acceleration zone, the final 2 metres as a deceleration zone, and the middle 10-metre section as the measurement zone. Participants will be asked to walk the specified distance at a natural walking speed that feels comfortable to them. The measurement will be taken by recording the time elapsed from the moment the participant enters the central 10-metre section until the moment they exit it, using a stopwatch to record the time in seconds. The test will be repeated three times, and the average of the measurements will be used in the analysis.
