“…Active ROM of the ankle during gait was altered in patients with LAS18 38 55 (n=545; Level 2). Changes in kinematics of both the ankle45 56–59 (n=150; Level 3), knee and hip38 43 52 53 60–64 (n=468; Level 3) were reported, substantiating the hypothesis that these are the consequence of a protection strategy to prevent future inversion sprains. Whereas in patients with LAS no differences were found in muscle activity compared with healthy controls65 (1 SR; Level 2), in patients with CAI proximal inhibitory muscle changes of the hamstrings and quadriceps were found66 (n=41) and a longer muscle response time67–70 (n=162; Level 3).…”

“…1 Furthermore, up to 70% of patients with LASs may develop chronic ankle instability (CAI), a condition characterized by perceived instability, recurrent episodes of giving way and sprains, and mechanical or sensorimotor impairments. 3 The sensorimotor impairments associated with CAI include impaired proprioception 4 and neuromus-cular control 5 in the lower extremity. These impairments can also have long-term health consequences (eg, osteoarthritis), thereby reducing the quality of life.…”

Context Patients with chronic ankle instability (CAI) exhibit deficits in neuromuscular control, resulting in altered movement strategies. However, no researchers have examined neuromuscular adaptations to dynamic movement strategies during multiplanar landing and cutting among patients with CAI, individuals who are ankle-sprain copers, and control participants. Objective To investigate lower extremity joint power, stiffness, and ground reaction force (GRF) during a jump-landing and cutting task among CAI, coper, and control groups. Design Cross-sectional study. Setting Laboratory. Patients or Other Participants A total of 22 patients with CAI (age = 22.7 ± 2.0 years, height = 174.6 ± 10.4 cm, mass = 73.4 ± 12.1 kg), 22 ankle-sprain copers (age = 22.1 ± 2.1 years, height = 173.8 ± 8.2 cm, mass = 72.6 ± 12.3 kg), and 22 healthy control participants (age = 22.5 ± 3.3 years, height = 172.4 ± 13.3 cm, mass = 72.6 ± 18.7 kg). Intervention(s) Participants performed 5 successful trials of a jump-landing and cutting task. Main Outcome Measure(s) Using motion-capture cameras and a force plate, we collected lower extremity ankle-, knee-, and hip-joint power and stiffness and GRFs during the jump-landing and cutting task. Functional analyses of variance were used to evaluate between-groups differences in these dependent variables throughout the contact phase of the task. Results Compared with the coper and control groups, the CAI group displayed (1) up to 7% of body weight more posterior and 52% of body weight more vertical GRF during initial landing followed by decreased GRF during the remaining stance and 22% of body weight less medial GRF across most of stance; (2) 8.8 W/kg less eccentric and 3.2 W/kg less concentric ankle power, 6.4 W/kg more eccentric knee and 4.8 W/kg more eccentric hip power during initial landing, and 5.0 W/kg less eccentric knee and 3.9 W/kg less eccentric hip power; and (3) less ankle- and knee-joint stiffness during the landing phase. Concentric power patterns were similar to eccentric power patterns. Conclusions The CAI group demonstrated altered neuromechanics, redistributing energy absorption from the distal (ankle) to the proximal (knee and hip) joints, which coincided with decreased ankle and knee stiffness during landing. Our data suggested that although the coper and control groups showed similar landing and cutting strategies, the CAI group used altered strategies to modulate impact forces during the task.

“…Another study reported that 25% of the injuries relevant to sports involved ankle sprains 7 ) . Moreover, 40–70% of those who suffer an ankle sprain have the potential risk of chronic ankle instability if the sprain goes untreated 8 ) . College students who actively participate in sports activities therefore should pay special attention to physiotherapy for ankle sprains.…”

[Purpose] The aim of present study was to identify the impact that recent virtual reality training programs used in a variety of fields have had on the ankle’s static and dynamic senses of balance among subjects with functional ankle instability. [Subjects and Methods] This study randomly divided research subjects into two groups, a strengthening exercise group (Group I) and a balance exercise group (Group II), with each group consisting of 10 people. A virtual reality program was performed three times a week for four weeks. Exercises from the Nintendo Wii Fit Plus program were applied to each group for twenty minutes along with ten minutes of warming up and wrap-up exercises. [Results] Group II showed a significant decrease of post-intervention static and dynamic balance overall in the anterior-posterior, and mediolateral directions, compared with the pre-intervention test results. In comparison of post-intervention static and dynamic balance between Group I and Group II, a significant decrease was observed overall. [Conclusion] Virtual reality programs improved the static balance and dynamic balance of subjects with functional ankle instability. Virtual reality programs can be used more safely and efficiently if they are implemented under appropriate monitoring by a physiotherapist.
