Background: Active inversion and eversion ankle range of motion (ROM) is widely used to evaluate treatment effect, however the error associated with the available measurement protocols is unknown. This study aimed to establish the reliability of goniometry as used in clinical practice.
Methods: 30 subjects (60 ankles) with a wide variety of ankle conditions participated in this study. Three observers, with different skill levels, measured active inversion and eversion ankle ROM three times on each of two days. Measurements were performed with subjects positioned (a) sitting and (b) prone. Intra-class correlation coefficients (ICC[2,1]) were calculated to determine intra- and inter-observer reliability.
Results: Within session intra-observer reliability ranged from ICC[2,1] 0.82 to 0.96 and between session intra-observer reliability ranged from ICC[2,1] 0.42 to 0.80. Reliability was similar for the sitting and the prone positions, however, between sessions, inversion measurements were more reliable than eversion measurements. Within session inter-observer measurements in sitting were more reliable than in prone and inversion measurements were more reliable than eversion measurements.
Conclusion: Our findings show that ankle inversion and eversion ROM can be measured with high to very high reliability by the same observer within sessions and with low to moderate reliability by different observers within a session. The reliability of measures made by the same observer between sessions varies depending on the direction, being low to moderate for eversion measurements and moderate to high for inversion measurements in both positions.

Background: Foot orthoses (FOs) are commonly prescribed to reduce pain and improve function in individuals with musculoskeletal disorders, including those with chronic metatarsalgia (CM). Reducing the mechanical overload under the metatarsal heads during locomotion is the central point of the treatment for CM. Medially wedged FOs (MWFOs) with a metatarsal pad could further reduce pressure loading under the metatarsal heads and modify foot and ankle biomechanics compared to standard FOs (SFOs).

Total talus replacement has been demonstrated to increase ankle instability. However, no studies have explored how to enhance postoperative stability. This study aims to explore the effect of collateral ligament reconstruction on ankle stability by finite element analysis.

Background: We aimed to synthesize the kinematics and kinetics during landing and walking/running tasks of ankle copers compared with patients with chronic ankle instability and controls.
Methods: We systematically searched PubMed, CINAHL, SPORTDiscus, and Web of Science. Tri-planar lower extremity biomechanics (joint angle and moment at maximum and initial contact, and joint displacement) were synthesized using standard mean difference and 95 % confidence intervals.

Background: Ankle joint position sense (AJPS) accuracy and postural control are crucial for maintaining balance and stability, particularly in individuals with plantar fasciitis who may experience proprioceptive and functional impairments. Understanding how psychosocial factors, such as pain catastrophizing, and biomechanical measures, like muscle strength and gait parameters related to proprioception and postural control, can inform more effective treatment approaches. This study aimed to (1) examine the relationship between AJPS accuracy and biomechanical factors-including postural stability, lower limb muscle strength, and gait parameters-in individuals with plantar fasciitis d (2) analyze the impact of psychosocial factors, including pain catastrophizing, physical activity level, and quality of life, on AJPS accuracy and postural control in this population.

Background: Posterior tibialis tendon dysfunction (PTTD) is a debilitating condition that leads to biomechanical changes, for which foot orthoses are often prescribed to attenuate. There is a need to improve the ability to predict these biomechanical alterations, determine the biomechanical effectiveness of foot orthoses, and anticipate their effects on individuals with PTTD during gait.
Research Question: Is the supination resistance test (SRT) reliable, and capable of predicting foot and ankle biomechanics, as well as the biomechanical effects of foot orthoses in individuals with PTTD during gait?
Methods: Twenty-one individuals with PTTD participated with supination resistance measured over two sessions.
