“…Regarding prophylactic braces, several studies have shown that in comparison to non-braced conditions, brace use better controlled knee kinematics during single leg hop, cut, pivot and jump landing tasks (6,(21)(22)(23). Some studies have also reported improved knee proprioception (5,24), while others did not observe improved proprioception compared to non-braced conditions (7,25). Some studies have also reported improved knee kinetics during hop landings or at least knee kinetics that did not compromise performance (26,27).…”

Introduction. This study measured knee frontal plane projection angle (FPPA) and sports safety and performance perceptions of female athletes during a single leg forward hop down and stabilization (SLFHS) for 3 conditions (standard knee sleeve, no device and distal thigh compression garment (DTCG)). The hypothesis was that the DTCG group would display superior dynamic knee valgus FPPA compared to the standard knee sleeve and no device groups. Methods. Eighteen healthy college athletes participated in this prospective cohort study with a randomized device order. FPPA was measured during SLFHS using two-dimensional biomechanical techniques to estimate dynamic knee valgus loading. A 10-cm visual analog scale survey collected data regarding subject perceived knee control, sports movement capability and overall satisfaction for each condition. Pearson correlations delineated knee valgus, safety and performance relationship perceptions (p < 0.05). Results. Mean/maximum dynamic knee valgus FPPA was lowest during the DTCG condition (8.7 ± 6°/12.2 ± 7°), or a 19.4%/21.3% range of motion reduction compared to the standard knee sleeve (10.8 ± 7°/15.5 ± 8°) and a 21.6%/17% reduction compared to the no device (11.1 ± 7°/14.7 ± 7°) conditions. Chi-square tests revealed that the T:25 group displayed a greater proportion of subjects with a "1" score (≤threshold value) than the standard knee brace or no device groups for both mean (one-sided p value = 0.02) and maximal (one-side p value = 0.049 FPPA). In relationship to maximum dynamic knee valgus FPPA, the DTCG was the best overall condition (r = 0.61, p = 0.007), relating more strongly to perceived knee control (r = 0.63, p = 0.005) and sports movement capability (r = 0.64, p = 0.004). Conclusions. Compared to standard knee sleeve and no knee device conditions, the T:25 device provided better dynamic knee valgus FPPA control and stronger subject perceptions of best overall condition, knee control and sports movement capability.

“…Subjective athlete perceptions of the T:25 suggests that use compliance would likely be good. Devices such as the T:25 may represent the threshold of a significant shift in protective and performance enhancing knee protective device development (24).…”

External supports that reduce ankle joint mobility such as ski-boots can impair postural control of healthy participants. Although this disruptive effect has been attributed to the rigidity of the external supports, the results remained controversial and no study has been conducted in order to evaluate the influence of ski-boots rigidity. Hence, the question about the influence of ankle support rigidity on postural control remains open. This study was therefore undertaken in order to investigate the effect of ski-boots rigidity on postural control. Ten healthy active participants were recruited. The wearing of soft and rigid ski-boots was compared to barefoot while standing on a seesaw generating mediolateral and anteroposterior instability. Centre of pressure displacements were sampled with a force platform. The surface electromyographic activity of the main muscles from the leg, thigh and trunk was recorded. A motion analysis system was also used to calculate the ankle, knee and hip angles. The results did not reveal any negative influence of ski-boot rigidity on postural control but rather suggest a less active postural control with the rigid ski-boots which offered a higher mechanical contribution.
