Epidemiological Study of Track-and-Field Meets On-Field Medical Care.

Background: Most epidemiological studies on track-and-field meets have been limited to the Olympics and world championships. These are meets in which only high-performance athletes participate at a certain time of the year. In contrast, epidemiological studies on athletes of various ages and across different seasons may provide health care providers with valuable insights into injury prevention and on-field medical care.

Relationship between the affective dimension of pain and site of the disorder: A cross-sectional study.

Background: Pain is a complex experience with both sensory and affective dimensions, and the affective dimension can increase the risks of chronic pain development. It is thus critical to identify factors influencing the affective dimension of pain.

Objective: This study aimed to identify the relationship between the affective dimension of pain and disorder site (primary pain source).

Gender differences in the restoration of knee joint biomechanics during gait after anterior cruciate ligament reconstruction.

Background: The aim of our study was to evaluate the effects of gender on recovery of knee joint biomechanics over the stance phase of gait after reconstruction of the anterior cruciate ligament (ACL).

Methods: Gait parameters and knee joint kinematics and kinetics were compared in 32 patients (16 male and 16 female) who underwent ACL reconstruction for a unilateral ACL deficiency, with comparison to an age-, height-, and weight-matched Control group. Knee flexion, adduction and tibial rotation angles were measured and knee extension and abduction moment was calculated by inverse dynamics methods.
