Abstract: Ankle joint Exercise Range of motion TorqueBackground: Limited ankle dorsiflexion (DF) range of motion (ROM) is associated with mechanical dysfunctions and chronic ankle instability.Uphill treadmill walking exercise (UTWE) has the potential to improve ankle mobility and function.Objects: This study aimed to examine the immediate effects of a 15° UTWE on DF ROM and torque generation in patients with limited DF. Methods:The study included 20 adults, comprising 10 males and 10 females, with a mean age 28 years and a passive DF range of 5°-12°.After baseline assessments, participants completed 30 minutes of UTWE on a 15° incline treadmill, followed by post-assessments.DF ROM was evaluated during the stance phase of gait, and in both open-kinematic-chain (OKC) and closed-kinematic-chain (CKC) conditions using a goniometer and Image J software.DF and plantar flexion (PF) peak torque were measured with a Biodex Dynamometer.Results: Post intervention, maximum DF ROM during the stance phase of gait increased significantly from a mean of 8.54° ± 3.97° to 11.03° ± 4.41°.The DF ROM in the OKC and CKC conditions increased significantly from a mean of 8.90° ± 0.62° and 21.55° ± 0.72° to 18.00° ± 1.13° and 28.20° ± 1.00°, respectively (p < 0.0001).DF peak torque increased from 16.20 ± 1.28 N/m to 21.52 ± 1.39 N/m, and PF peak torque increased from 25.26 ± 2.51 N/m to 44.22 ± 4.20 N/m (p < 0.0002).Conclusion: UTWE significantly enhanced DF ROM and ankle torque, indicating that it may be an effective intervention for improving ankle function and preventing injury in clinical and rehabilitation settings.
