“…The information from our study may support their hypothetical cascade of CAI events 47 and provide insight into how copers successfully develop strategies within the sensorimotor system to manage the previous ankle injury. The small aMNs are primarily engaged in the H-reflex test.…”

“…Wikstrom and Brown 47 suggested that a successful reorganization of the sensorimotor system after ankle sprain is the critical point when individuals develop CAI or become copers. The information from our study may support their hypothetical cascade of CAI events 47 and provide insight into how copers successfully develop strategies within the sensorimotor system to manage the previous ankle injury.…”

Neuromuscular and mechanical deficiencies are commonly studied in participants with chronic ankle instability (CAI). Few investigators have attempted to comprehensively consider sensorimotor and mechanical differences among people with CAI, copers who did not present with prolonged dysfunctions after an initial ankle sprain, and a healthy control group.Context: To determine if differences exist in spinal reflex excitability and ankle laxity among participants with CAI, copers, and healthy controls.Objective: Case-control study.Design: Research laboratory.Setting: Thirty-seven participants with CAI, 30 participants categorized as copers, and 26 healthy control participants.Patients or Other Participants: We assessed spinal reflex excitability of the soleus using the Hoffmann reflex protocol. Participants' ankle laxity was measured with an instrumented ankle arthrometer. The maximum Hoffmann reflex : maximal muscle response ratio was calculated. Ankle laxity was measured as the total displacement in the anterior-posterior directions (mm) and total rotation in the inversion and eversion directions (°).Main Outcome Measure(s): Spinal reflex excitability was diminished in participants with CAI compared with copers and control participants (P = .01). No differences were observed among any of the groups for ankle laxity.Results: Changes in the spinal reflex excitability of the soleus that likely affect ankle stability were seen only in the CAI group, yet no mechanical differences were noted across the groups. These findings support the importance of finding effective ways to increase spinal reflex excitability for the purpose of treating neural excitability dysfunction in patients with CAI.Conclusion:

“…Such an animal model could also support and/or further develop contemporary theoretical models associated with CAI. Although multiple models exist and overlap, some have hypothesized that the development of CAI is due to a cascade of events that stem from the initial ankle sprain consequences (7,30,31). Furthermore, an animal model could be used to address Hertel's (7) call to focus on potential points of intervention to limit sensorimotor deficits (i.e., organismic constraints) via testing a range of outcomes at multiple time points after injury while also exploring the initial physiologic site of pathology.…”

“…For the purposes of this investigation, CAI was operationally defined as the presence of balance impairments 1 yr after the injurious event. The time point of 12 months, although not directly translatable between humans and mice, was chosen for the following three reasons: 1) after 12 months, the risk of a recurrent lateral ankle sprain is similar to the risk of a first-time lateral ankle sprain in humans (28), 2) 12 months has been recommended as the time needed to satisfactorily determine whether an individual will become a coper (i.e., a person that has sprained their ankle but will not develop CAI in humans (30), and 3) 12 months was hypothesized to be sufficient for CAI-like symptoms to develop because this period is slightly greater than 50% of the lifespan for this mouse strain. Furthermore, we hypothesize that surgically induced ankle sprains will result in decreased physical activity levels but not spatial gait outcomes, on the basis of the human CAI literature.…”

Objective: The Star Excursion Balance Test (SEBT) and Y-Balance Test (YBT) have been commonly applied to measure dynamic postural stability ability. These two tests are utilized interchangeably in various settings. However, they could in fact require different movements to assess dynamic postural stability, as one uses a platform and different measuring techniques than the other. The purpose of this study was to determine if there was a significant difference in the kinematic patterns in physically active population while performing the SEBT and the YBT.Method: Seventy participants performed in the Anterior (AN), Posteromedial (PM), and Posterolateral (PL) directions of the SEBT and the YBT. The kinematics of hip, knee, and ankle in sagittal plane was calculated and analyzed. Paired-sample t-tests were performed to compare joint angular displacement in the ankle, knee, and hip between the SEBT and the YBT.Results: Significant differences in angular displacement at the hip, knee, and ankle joints in the sagittal plane between performance on the SEBT and on the YBT were observed.Conclusion: Clinicians and researchers should not apply these dynamic postural control tasks interchangeably from one task to another. There appear to be kinematic pattern differences between tests in healthy physical active population.
