“…Although the overall postural changes were underestimated in the literature, knee and lower extremity alignment (51), knee joint position sense (25), knee joint laxity and loading (12), gait parameters (52), postural control, kinesthesia, and balance (13,14) have all been relevant since the menstrual cycle might be a potential risk factor for anterior cruciate ligament injuries in active women. Postural stability parameters were assessed in our study.…”

“…In some studies, increased levels of progesterone in the luteal phase were related to increased intensity of premenstrual complaints (anxiety, tension, irritability) (6,7), while in other studies decreased progesterone levels were found to be related to more pronounced negative mood changes (8,9). Moreover, the neuromusculoskeletal effects relating to muscle strength and stretch reflex (10), ligament laxity (11), biomechanical characteristics (12), and postural control (13,14) throughout the menstrual cycle have been investigated in the literature in order to determine the relationship between injury mechanisms in women and the differences between the sexes. Menarche itself was declared to be a risk factor in some sports and conditions (15).…”

Background/aim: To investigate differences in state anxiety, spinal posture and mobility, postural competency, and stability across the menstrual cycle in active women. Materials and methods:Thirteen physically active women (18-25 years) with a regular menstrual cycle were recruited. Anxiety with the Spielberger State Trait Anxiety Inventory; spinal posture, mobility, and competency with a Spinal Mouse device (Idiag, Fehraltorf, Switzerland); and postural stability with a Biodex Balance System SD (Biodex Medical Systems, Inc., Shirley, NY, USA) were evaluated across phases of the menstrual cycle.Results: No significant differences were observed between phases of the menstrual cycle for state anxiety, spinal posture, mobility, or competency (P > 0.05). No differences were found for static postural stability (P > 0.05); however, a significant difference was detected in dynamic postural stability within three phases of the menstrual cycle (P < 0.05). The highest values of overall stability, anterior-posterior and mediolateral indexes were at menses; the lowest values were at the midluteal phase. Conclusion:State anxiety, spinal posture, mobility, and postural competence did not change across the menstrual cycle. However, dynamic stability declined in menses. Improving awareness of dynamic stability impairment during menses may be important toward injury prevention in active women.

“…An increasing number of women incur knee injuries during sports activities (Beynnon et al 2005;Eiling et al 2007;Kjaer and Hansen 2008;Hansen et al 2009b; Lee et al 2013aLee et al , 2015. The incidence, especially of non-contact anterior cruciate ligament injuries, is 2 to 8 times greater in women compared to men when participating in the same sports activities (Park et al 2009a, b;Hansen et al 2009b;Boden et al 2010;Lee et al 2013a;Stijak et al 2015).…”

Ankle and foot injuries are common among athletes and physically active individuals. The most common residual disability, ankle sprain, is characterized by instability along with postural sway. If the supporting structures around a joint become lax, posture stability and balance are also affected. Previous studies have examined muscle stiffness and elasticity and postural sway separately; however, the relationship between these factors is yet unknown. It is well known that the levels of sex hormones, especially estrogen, change in women over the phase of the menstrual cycle. Therefore, this study examined the relationship between the mechanical properties of tissue and balance activity using a non-invasive digital palpation device to determine if they undergo any changes over the menstrual cycle in young women. Sixteen young women with regular menstrual cycles completed the study. Tone, stiffness, and elasticity of the ankle muscles (lateral gastrocnemius, peroneus longus, and tibialis anterior) were measured using a non-invasive digital palpation device. Postural sway was recorded while the participants performed balance tasks during ovulation and menstruation. Significantly greater posture sway characteristics and ankle muscle elasticity were found during ovulation than during menstruation; lower tone and stiffness of the ankle muscles were observed at ovulation (p < 0.05). Additionally, weak-to-strong relationships between ankle muscle mechanical properties and postural sway characteristics were found (p < 0.05). These results suggest the effect of estrogen on human connective tissues. We therefore postulate that estrogen increases joint and muscle laxity and affects posture stability according to the phase of the menstrual cycle.

Relationship between knee joint laxity and knee joint mechanics during the menstrual cycle

Abstract: Knee laxity correlates positively with knee joint loads, and increased knee laxity during the menstrual cycle may be a potential risk factor for anterior cruciate ligament injuries in certain women during sports activity.
