Progression and risk factors of hallux valgus angle in elite adolescent dancers: a cohort study.

Introduction: To the best of our knowledge, no previous studies have linked the progression of hallux valgus (HV) with plantar pressure distribution. Therefore, this study aimed to determine the progression of HV angle in elite adolescent dancers and evaluate the risk factors associated with foot plantar pressure during demi-pointe movement.

Methods: For this cohort study, 40 adolescent dancesport dancers (age: 14.

Hallux valgus in preprofessional adolescent dancesport athletes: Prevalence and associated training factors.

Background: This study aimed to determine the risk factors of hallux valgus angle among preprofessional adolescent dancesport athletes.

Methods: A total of 275 athletes, (73 males and 202 females) aged between the ages of 11 and 18 years, participated in this study. A cross-sectional questionnaire was used to survey their demographic characteristics (sex and age), training information (starting age, weekly training time, and athletic career [number of years of training at this specific dancesport school]), and measured their height and weight.

The Effect of Foot Deformity and First Metatarsophalangeal Joint Plantar Pain on Performance in DanceSport Athletes.

Background: Adolescent DanceSport athletes who regularly dance in high heels have a higher possibility of developing hallux valgus deformity and foot pain. We believe that the occurrence of foot disorders may change the loading on their feet, which thus affects the athletic performance of those adolescents.

Methods: A total of 63 adolescent DanceSport athletes (16 boys, 47 girls) were included.

The prevalence and effect of the sites of pain in female soccer players with medial shin pain.

Background: Female soccer players are often diagnosed with medial shin pain, which includes tibial stress fracture, medial tibial stress syndrome, and chronic exertional compartment syndrome. As the possibility of varied sites of pain affecting sports activities has not been fully researched, an urgent discussion and evidence is required. This study investigates the prevalence and effect of sites of pain on the sports activities of female soccer players with medial shin pain.

Presence of adipose tissue along the posteromedial tibial border.

Purpose: The flexor digitorum longus and posterior tibial tendon as well as the perforating veins are located along the distal posteromedial tibial border. Adipose tissue may surround these structures and possibly play a role in reducing mechanical stress. This study aimed to examine the adipose tissue along the posteromedial tibial border via magnetic resonance imaging (MRI), ultrasound, and gross anatomical examination.

Greater knee varus angle and pelvic internal rotation after landing are predictive factors of a non-contact lateral ankle sprain.

Objectives: This study aimed to clarify the kinematic, kinetic characteristics associated with lateral ankle sprain.

Design: A 16-month prospective cohort study.

Setting: Laboratory.

Immediate effects of plantar vibration stimuli during static upright posture following total hip arthroplasty in females.

Purpose: Proprioceptive function of the lower limbs deteriorates in patients following total hip arthroplasty. Patients show poor balance and rely more on visual information than proprioceptive information. Plantar vibration stimuli can mechanically enhance somatosensory input from the plantar cutaneous mechanoreceptors, thereby improving static balance.

Comparison of the Position-Matching and Position-Reproducing Tasks to Detect Deficits in Knee Position Sense After Reconstruction of the Anterior Cruciate Ligament.

Context: Deficits in knee position sense following reconstruction of the anterior cruciate ligament (ACL) can delay an athlete's return to sport participation and increase the risk of reinjury. Deficits in position sense postreconstruction have been evaluated using either a position-reproducing or position-matching task.

Objective: The aim of our study was to combine both to determine which assessment would be more effective to identify deficits in knee position sense.

The reliability, and discriminative ability of the identification of functional ankle instability questionnaire, Japanese version.

Objective: To assess the discriminability as well as the reliability, and internal consistency of the Identification of Functional Ankle Instability questionnaire translated into Japanese (IdFAI-J).

Design: Cross-sectional study.

Setting: Collegiate athletic training/sports medicine clinic.
