Biomechanically, the gluteus medius (GMED) controls femoral motion during dynamic lower-extremity motion, and counteracts gravity to stabilize the pelvis in a single-leg stance. 1 , 2 However, when the GMED becomes weak, numerous neuromuscular problems including hip joint pathology, lateral hip

athletic training staff with pain in her left hip at the beginning of competition season. She reported no previous history of hip, groin, or pelvis pathology, but did have a history of a pars fracture at L2 and L5 and a herniated disc at T12. Her chief complaint was left hip pain initially originating

The importance of lower-extremity function in baseball pitching is well recognized. In particular, the concern with hip function of baseball pitchers has been growing recently. The hip function is involved in the motion and stability of the pelvis, weight shift from a pivot leg (leg on the same

recreational runners according to differences in gait kinematics at the ankle, knee, and hip joints as well as the foot and pelvis segments in all 3 planes of motion. We hypothesized that we could separate and classify competitive and recreational runners and that the projected differences between groups would

, handheld bottles restrict natural motion of the control elbow, minimize trunk-to-pelvis crossover, and shift the COM for stability. Partially full bottles introduce a complicating factor of sloshing when moved. Sloshing fluid mass from bottles in the hand or worn at the waist creates momentum forces that

An estimate of the displacement of the pelvis center of mass in the medial–lateral direction (displacement of the pelvis ML-COM) was calculated by averaging the medial–lateral displacement of the anterior and posterior

Sufficiently high levels of muscle activation are required for the development of muscle strength. To enhance athletic performance or rehabilitation therapies related to the lumbar region, the musculature of the hips, pelvis, and trunk is often a primary exercise target. 1 Furthermore, “core

Deep water running research to date has mainly focused on its cardiovascular effects. 2 , 10 Kaneda et al 8 has reported increased obliquus externus abdominis and erector spinae (ES) muscle activity for trunk and pelvis control during DWR compared with walking on land (LW). However, that study did
