Summary: The aim of this study was to investigate the effects of femoral anteversion on hip abductor weakness and frontal plane pelvis-hip biomechanics during walking. The results showed that femoral anteversion may not be associated with hip abductor muscle weakness and may not lead to hip adduction and pelvic depression. Increased pelvic rotation and hip internal rotation during walking could be considered compensatory mechanisms for femoral head-acetabulum alignment in the frontal plane.

Summary: The study focused on female patients with hip osteoarthritis and found that preoperative muscle strength, age, weight, physical activity, and disease duration are significant factors affecting postoperative muscle strength, with the impact of preoperative muscle strength on knee extensor strength depending on age.

Summary: The study revealed that greater energy used during walking was associated with lower self-reported physical activity, while lower hip abductor strength was linked to decreased physical activity. Together, these variables could predict 55.5% of the variance in self-reported physical activity, indicating potential intervention targets to promote physical activity in this population.

Summary: This study aimed to assess and quantify hip abductor muscle strength deficits after total hip arthroplasty (THA). Results showed an average strength deficit of 18.6% preoperatively, with gradual improvement postoperatively over 24 months, possibly without complete recovery. High-quality evidence is largely missing for cautious interpretation of these findings.

Summary: Sex differences were found in hip adduction during running, with women showing greater angles, lower hip abductor strength, and different femur morphology than men. Femoral anteversion was identified as a significant predictor of hip adduction angle during late swing and stance phases.

Summary: This study compared hip and knee muscle torque and balance performance between individuals with chronic ankle instability, copers, and healthy controls. The results showed that individuals with chronic ankle instability had weaker knee and hip muscles and poorer balance compared to copers and controls. Additionally, there was a significant correlation between hip muscle strength and balance performance.

Summary: This study investigated the relationship between frontal plane kinematics and hip abductor muscles strength in elite handball athletes. The results showed a significant negative correlation between hip abductor muscles strength and pelvic drop angle, and a significant positive correlation between hip abductor muscles strength and femoral adduction angle and knee valgus angle.

Summary: This study investigated the effects of high load resistance training (HL-RT) and low load resistance training (LL-RT) combined with aerobic training (AT) compared to AT alone on body composition and physical performance in patients with coronary artery disease (CAD). The results showed that both HL-RT and LL-RT combined with AT resulted in similar improvements in physical performance, which were superior to AT alone.

Summary: This study aims to assess the feasibility, reliability, and validity of a new measurement method for assessing hip abductor strength in individuals aged 65 years and older. The study consists of two parts: investigating feasibility and reliability in a clinical setting, and evaluating construct and criterion validity.

Summary: The aim of this systematic review was to assess the effectiveness of hip abductor strengthening on knee joint loading, knee pain and functional outcome measures in patients with knee osteoarthritis. The results showed that hip abductor strengthening significantly reduced knee pain and improved functional outcome measures. All included studies concluded that hip abductor strengthening had a positive impact on knee pain and functional outcomes.

Summary: This study investigated the associations between hip abductor muscle strength, RTD (rate of torque development), RTD-SF (rate of torque development scaling factor) and responses to external postural perturbations in older adults. The results showed a moderate positive correlation between RTD-SF and the consistency of postural responses at the lowest perturbation intensity. No other significant relationships were found.

Summary: This study aimed to investigate the challenge posed by progressively unstable balance devices to bipedal stance during early functional rehabilitation in THA patients. The results showed that increasingly compliant balance pads provided a progressive challenge, while the challenge posed by the oscillating platform was lower and independent of the ability to stand independently.

Summary: This study examined the differences in postural adjustments between erect, hyperlordotic, and swayback postures when facing external perturbations. The findings suggest that adopting hyperlordotic and swayback postures alters the contributions of the active and passive subsystems of the spine in postural control, potentially reducing the spine's ability to withstand loading and shear forces.

Summary: This study investigated the differences in lumbar and hip movements during gait and muscle activities related to knee osteoarthritis (KOA) patients and healthy participants. The results showed that KOA patients used a hyperlordotic lumbar and hip flexed strategy, leading to excessive stress on the lower extremity joints during gait.

Summary: This study investigated sex differences in lower limb dynamic joint stiffness (DJS) during walking in older adults. The results showed that ankle DJS was lower in older women, which was caused by the reduced ankle plantarflexion moment. However, knee DJS did not elucidate the cause of knee osteoarthritis (OA) in older women.

Summary: The study found that the reliability of stiffness, viscosity, and inertia of the ankle joint was good to excellent during standing. During walking, the reliability of stiffness and viscosity was also good to excellent, while that of inertia was fair to good. The minimal detectable change (MDC) ranged widely, but was higher for inertia during walking.

Summary: This study investigates the effects of footwear type, navicular drop and ankle pronation on lower limb joint stiffness during running. The results show that navicular drop and dynamic ankle pronation do not affect joint stiffness, but footwear type significantly affects joint stiffness. Conventional footwear increases ankle and hip joint stiffness while reducing knee joint stiffness, which may have implications for injury risk.

Summary: This systematic review is the first to compile evidence on the effect of the menstrual cycle on postural control. The evidence regarding the influence of the menstrual cycle on postural control is unclear. However, a trend of decreased postural control from the early follicular phase to the ovulatory phase was observed in balance tasks that eliminated or altered sensory input.
