plates with 4 retroreflective marker clusters were attached to the torso and pelvis, as well as bilateral thighs, shanks, and heels of the shoes for segment tracking during motion trials. Once markers were attached in the proper locations, a 3-second standing calibration trial was collected. Calibration

the trunk, pelvis, and lower extremity of the participants. Locations of the markers were collected by a 7-camera motion capture system (Vicon Motion System Ltd, Oxford, United Kingdom) at 120 Hz. The ground reaction forces (GRFs) were measured by 2 force plates (Bertec Corporation, Columbus, OH) at

period, the postural treatment of athletes with LBP was modified; it was addressed by changing the position of the pelvis in 90° flexion, with the knees in 180° maintained by the therapist associated with deep diaphragmatic breathing, and the patient always lying supine in bed therapy. More specifically

landing, they had to place their hands immediately on their pelvis and maintain balance for at least 5 seconds. For the actual testing procedure, 5 successful trials were registered for each of the 2 jump tasks. Trials were discarded if participants did not “stick” the landing, removed their hands from

so when imbalances occur, alterations in mechanical alignment and load affect the kinetic chain. For example, muscle tightness of the hamstrings pulls the ipsilateral innominate bone of the pelvis posteriorly, shortening the abdominal muscles. In return, the erector spinae and hip flexors become

differences could have led to differences in the EMG activity. Gluteus Medius The EMG activity of the GMED ranged from 26.3% (13.4%) to 54.6% (26.1%) MVIC (Table  6 ) during the 8 directions of the SEBT. The highest activity was observed in the medial direction because, during the task, the pelvis of the

Coordination variability between the pelvis and trunk was lower in runners with current low back pain compared
