“…Some studies have shown no difference between males and females in dynamic balance and tandem gait. 23,24 However, our findings were consistent with others showing that females had less dynamic postural control 25 and walked more slowly than males. 26 Potential reasons for sex differences in dynamic balance include differences in muscle strength and the speed of muscle contractions.…”

Our findings suggest that the tandem-gait test had a high false-positive rate in high school athletes. Given that more than 75% of healthy participants failed the tandem-gait test, the 14-second cutoff appears to have limited clinical utility in the adolescent population. Functional movement deficits after concussion need to be accounted for, but the 14-second cutoff for the SCAT3 tandem-gait test does not appear to be an ideal way to assess these deficits in high school athletes.

“…However, the exact variability of ankle laxity throughout the menstrual cycle remains controversial. In fact, Ericksen and colleagues showed no differences in ankle laxity or dynamic postural control according to hormonal fluctuations during the menstrual cycle (Ericksen and Gribble 2012).…”

Lateral ankle sprains are one of the most common injuries among the physically active subjects. Ankle inversion-eversion laxity is greater and dynamic postural control is less in women compared with men. The purpose of this study was to examine differences in postural sway and its effects on the neuromuscular activities of the ankle stabilizing muscles during the menstrual cycle in young women. Fourteen young women with regular menstrual cycles participated in this experiment. Postural sway and electromyographic signals of the lateral gastrocnemius, peroneus longus (PL), and tibialis anterior (TA) were recorded while the participants performed eight different balance tasks at ovulation and early follicular phase during one full menstrual cycle. Significantly greater postural sway in the two most difficult balance tasks was observed at ovulation compared to that in the early follicular phase (p < 0.001). A similar pattern was also observed in terms of PL activity, while TA activity was significantly greater in the most difficult balance task at ovulation. In addition, TA-PL co-contraction (TA/PL ratio) was significantly higher at ovulation compared with that in the follicular phase in the two most difficult balance tasks (p < 0.01). Young women could benefit from increased understanding of the varying neuromuscular activation patterns throughout the menstrual cycle. The results of this study suggest that health professionals should be aware of the physiological effects and the shifts in neuromuscular strategies in each menstrual cycle phase in order to prevent increased risk of lower extremity injury.

“…As estrogen peaks at ovulation, these measurement times may have masked the results. 23 Another contributor to sway may be the increased body temperature seen at ovulation. 33 This would also increase laxity in the plantar fascia and other tendons and ligaments and contribute to the increased sway as tendons and ligaments are highly susceptible to small increases in temperature.…”
