Copers adopt an altered dynamic postural control compared to individuals with chronic ankle instability and controls in unanticipated single-leg landing

Effect of core stabilization exercise on risk factors for anterior cruciate ligament injury during single-leg landing in athletes

“…Afterwards, subjects had a surface electromyography device attached to them, landed on a 30cm high box to the landing point, and held the position for 3 seconds. Data analysis used muscle activity values measured 100ms after the subject's first contact, and measurements were performed three times and the average value was used [31]. The measured data were normalized using the maximum isometric contraction measured according to the manual muscle strength assessment method presented by Kendall et al [32].…”

Exploring the interplay between ankle muscle strength, postural control, and pain intensity in chronic ankle instability: A comprehensive analysis

“…These deficits manifest as increased sway and a reduced ability to make rapid adjustments in response to changes in surface or body position [ 12 ]. Such compromised PC not only elevates the risk of further ankle injuries but also hinders everyday activities and athletic performance [ 13 ]. Comprehending the complexities of PC in CAI holds significance in formulating precise rehabilitation strategies to enhance balance and stability [ 14 ].…”

Using clinician-oriented and laboratory-oriented assessments to study dynamic stability of individuals with chronic ankle instability

“…It is necessary to investigate the difference of lower extremities between Copers and CAIs using the dynamic stability tests with different concentrations and orientations. Although numerous studies have compared the YBT or TTS between CAIs and Copers, 14 , 30 , 31 , 32 they have not simultaneously evaluated the potential difference of YBT and TTS (two different oriented dynamic stability tests) between CAIs and Copers. The objective of this study was to compare dynamic postural control of participants with CAI and Copers using the TTS of the single-leg landing test and the YBT.…”
