The aim of our study was to evaluate whether the length of the free part of the Achilles tendon affects the mobility of the ankle joint in active motion without a load, as well as in functional motion with a body-weight load. We examined 36 healthy people, aged 21 to 30 years, and divided them into two groups: 1 (n = 15)—participants with a normal range of dorsiflexion in the ankle joint (20° or more), and 2 (n = 21)—participants with a reduced range of dorsiflexion in the ankle joint (below 20°). The length of the free part of the Achilles tendon was measured using ultrasonography. Ankle joint range of dorsiflexion was assessed, and a weight-bearing lunge test (WBLT) was conducted. Group 1 performed the WBLT better and demonstrated significantly greater Achilles tendon length compared to Group 2. A moderate, significant correlation was observed between ankle joint range of dorsiflexion and Achilles tendon length (r = 0.53, p < 0.05); between WBLT and Achilles tendon length (r = 0.61, p < 0.05); as well as between ankle joint range of dorsiflexion and WBLT (r = 0.63, p < 0.05). Thus, we can suggest that both the length of the tendon (measured by USG) and the ankle range of motion under a body-weight load (measured by WBLT) are good indicators regarding the range of foot dorsiflexion, but only up to specific values (6 cm of tendon length and 11 cm of WBLT reach). Therefore, Achilles tendon length, e.g., after injury and during tendon healing, may be monitored using the method of ultrasound imaging presented in this study.

Manipulation is commonly used by physiotherapists in the treatment of musculoskeletal disorders; however, there have been few studies evaluating its use in peripheral joints. The purpose of this study was to investigate the effect of manipulation on dorsiflexion range of movement at the ankle joint. Twenty asymptomatic subjects participated, one ankle acting as the experimental ankle and receiving the manipulation intervention, while the other ankle acted as the control. The manipulation studied was a longitudinal talocrural manipulation. Dorsiflexion range of movement was measured at 5 consecutive torque levels pre and post manipulation intervention in the experimental ankle and pre and post no intervention in the control ankle. These values were compared using analysis of trend within an analysis of variance framework. There was no statistically significant change in dorsiflexion range of movement following manipulation. It was concluded that in the case of asymptomatic subjects these results did not provide support for the experimental hypothesis that a single talocrural manipulation alters dorsiflexion range of movement. It was suggested that future research investigate the effects of manipulation in a symptomatic population.

[Purpose] The purpose of this study was to examine the correlation between weight-bearing (WB) and non-WB ankle dorsiflexion (DF) range of motion (ROM) and ankle movement during gait, including heel-rise time and ankle DF at heel-rise. [Subjects and Methods] Thirty healthy male subjects were recruited for this study. Ankle DF ROM of both feet was measured under the WB and non-WB conditions. Heel-rise time and ankle DF at heel-rise in both feet during gait were measured using a motion analysis system. Pearson product moment correlations were used to identify correlation ankle DF ROM and ankle movement during gait. [Results] Heel-rise time and ankle DF at heel rise were significantly correlated with WB ankle DF ROM. However, no correlations were found between ankle movement during gait and non-WB ankle DF ROM. [Conclusion] These findings demonstrate that WB ankle DF ROM measurements can be used to predict heel-rise time and ankle DF at heel-rise.

This article presents a series of case reports to describe the technique of ankle joint manipulation and its effects on common problems of the foot and ankle. The relationship between motion and pain is described, as are the effects of muscular inhibition on the presence of joint restriction and their association with pain in various joints remote to the ankle joint.
