Chronic ankle instability is characterized by a patient's being more than 12 months removed from the initial LAS and exhibiting a propensity for recurrent ankle sprains, frequent episodes or perceptions of the ankle giving way, and persistent symptoms such as pain, swelling, limited motion, weakness, and diminished self-reported function.

Knee Surg Sports Traumatol Arthrosc. Hertel J. Functional instability following lateral ankle sprain. Deficits have been reported in both the active and passive joint position sense of frontal- and sagittal-plane ankle motion, with CAI groups demonstrating more proprioceptive errors.60,61 The inability of patients with CAI to accurately sense the position of their ankle joint before initial contact during gait or landing has been theorized to increase the risk of recurrent ankle sprain because the foot is likely to contact the ground in a position that predisposes the ankle to move into supination rather than pronation during the loading response.62, Measures of force sense in all directions of ankle motion among patients with CAI have indicated that the ability to sense and regulate muscle-contraction output is impaired after joint injury, even in the absence of musculotendinous injury.6368 Interestingly, weak and nonsignificant correlations were found between measures of active position sense and force sense in patients with CAI, suggesting that these measures assess different constructs of somatosensation.69, Differences in cutaneous sensation have also been demonstrated between CAI and control groups. doi: 10.1016/j.otsr.2013.10.009. The effects of functional ankle instability on the performance of the Star Excursion Balance Test [abstract]. After an acute ankle sprain 20-40% of the injured develop chronic ankle instability. The SEBT is performed with a self-directed pace of movement of the reaching leg, with challenges to stability of the stance leg occurring at a much slower pace than the inversion-release platforms used by Konradsen21 and Beckman and Buchanan.7 Whether the apparent lack of muscle recruitment associated with decreased proximal joint movement in our CAI group is a result of central or peripheral nervous system alteration or, more likely, a combination of both is unclear.

Effects of reduced plantar cutaneous sensation on static postural control in individuals with and without chronic ankle instability. Instead, Freeman et al12 asserted that, (1) the afferent nerve fibres in the capsule and ligaments of the foot and ankle subserve reflexes which help to stabilise the foot during locomotion, and (2) when the foot or ankle is sprained partial deafferentiation of the injured joints occurs, so that (3) reflex stabilisation of the foot is impaired and the foot tends to give way.12(p678).

Sagittal-plane movement patterns at the ankle (plantar flexion-dorsiflexion), knee (flexion-extension), and hip (flexion-extension) were tested. Fears of movement and reinjury during functional activities have been reported in patients with CAI.80 Kinesiophobia is most often assessed with the Fear-Avoidance Beliefs Questionnaire81 and the Tampa Scale for Kinesiophobia (TSK-11).82 The Fear Avoidance Beliefs Questionnaire is a 16-item survey that addresses the fear of movement during physical activity and work.81 The TSK is an 11-item questionnaire that assesses fears of movement and reinjury.82 The perception that movement of the involved ankle will be harmful runs counter to the emphasis on therapeutic exercise as a primary treatment for CAI and represents an important obstacle to be managed when treating this condition. Lateral ankle sprains (LASs) are among the most common injuries incurred during participation in sport and physical activity, and it is estimated that up to 40% of individuals who Copyright 2020. Subjects lunged forward the distance equal to the individual leg length that had been measured at the beginning of the first session. Initially, we hypothesized that the different fatigue conditions might create altered contraction properties of the muscles at the affected joint and result in altered kinematics at that joint.

Lateral ankle sprains are one of the most common injuries among athletes.1 After initial injury, the rate of recurrence may be as high as 80% among active individuals.2 Altered mechanical joint stability due to repeated disruptions to ankle integrity with resultant perceived and observed deficits in neuromuscular control has been described as chronic ankle instability (CAI).3, Aspects of neuromuscular control may be quantified through measures of postural control. Persistent pain and stress are posited to substantially alter the neurosignature in a negative manner,27,28 whereas targeted therapies such as manual therapy and therapeutic exercise can alter it in a positive manner.

Documented impairments in static postural control result from musculoskeletal injury to the ankle.6,19,20,34,35 An injury that disrupts joint integrity, such as CAI, is theorized to impair afferent-efferent pathways that allow for maintenance of proprioception, kinesthesia, and ultimately neuromuscular control. Chronic psychological and physical stress associated with chronic pain can further diminish a patient's ability and willingness to participate in functional activities.27,28 The influence of pain on other impairments commonly seen among patients with CAI is likely to be clinically important, but currently these relationships are poorly understood. -.

Over the past 2 decades, substantial advances in our understanding of arthrokinematic restrictions in the ankle and foot complex have emerged in the manual therapy literature.4447 Restrictions in anterior-to-posterior glide of the talus on the tibia have been well documented as being associated with limited osteokinematic dorsiflexion of the talocrural joint in patients with lateral ankle instability.44,45,48 Also, small amounts of anterior displacement of the talus on the distal tibia may be associated with restricted glide of the talus.49 Furthermore, many patients have demonstrated anterior displacement of the distal fibula relative to the tibia and associated restriction of anterior-to-posterior glide of the distal fibula.50,51 Lastly, the potential for arthrokinematic restrictions at the subtalar, midtarsal, and tarsometatarsal joints has also been described.46,47, Patients recovering from LAS or with CAI often demonstrate restricted dorsiflexion ROM. The ability to integrate different sensory inputs appears to be compromised in CAI. PMC Acute injury to the lateral ankle ligaments produces specific pathomechanical impairments related to ligamentous and, potentially, other tissue damage around the ankle.

Increased variability in frontal-plane ankle kinematics during running among patients with CAI has been reported using linear variability calculations based on intraindividual standard deviations across multiple steps.135,136 During walking, ankle frontal-plane kinematic variability was amplified in patients with CAI during a dual-task paradigm.132 Conversely, Terada et al137 reported less stride-to-stride variability in frontal-plane ankle kinematics among patients using measures of sample entropy, a nonlinear variability estimate during single-task walking.

Systematic review of postural control and lateral ankle instability, part I: can deficits be detected with instrumented testing? During walking, patients with CAI have demonstrated less variability in frontal-plane ankle-hip coupling140 and greater variability in ankle frontal-knee sagittal-plane motions.141 During jogging, patients have exhibited less coupling variability between the ankle-hip and the ankle-knee in both frontal- and sagittal-plane motions.141, Patients with CAI have also been reported to require a higher level of gait disturbance, defined by alterations in walking speed and dual tasks, to reduce stride-time variability, a spatiotemporal gait measure, compared with healthy controls.142 This change was hypothesized to be due to less adaptability of the sensorimotor system in response to task constraints.142 Koldenhoven et al143 observed that patients with CAI had greater stride-to-stride variability in the location of their center of pressure during the first 10% of stance phase during walking compared with controls but no differences later in the stance phase, despite their center of pressure staying more lateral.144 Interestingly, the patients with CAI also exhibited less variability in electromyographic amplitude of the fibularis longus muscle throughout the swing phase and the beginning of the stance phase.143.
