Trunk and hip muscles play a critical role in controlling the motion of the trunk–pelvis segment and transferring energy between the lower- and upper-extremities. 1 Therefore, it is important to establish a reliable method to measure trunk and hip muscle strength that is also accessible

Following the standing calibration trial, subjects performed double-leg drop landings from a 31-cm high box

Also, 5% to 6% of adult sports injuries occur at the hip and pelvis. 9 – 11 It is important for allied health and fitness professionals to be able to recognize common hip musculoskeletal conditions and how they can affect movements, such as the squat. Of interest are the effects of common hip

adjusted the degree of hip flexion of the nontest limb to maintain the pelvis and lumbar spine in a neutral position, and the goniometric measurement was rerecorded. The range of hip extension was calculated by subtracting the baseline measurement from the second measurement angle. Figure 1 —Measurement of

clusters were used to track the thigh, shank, and foot segments during the movement trials. The pelvis was tracked by the markers placed on the posterior superior iliac spines and on the iliac crests. With the markers in place, a standing calibration trial was captured. The 3-dimensional positions of the

This is particularly important because turning is a complex motor task that involves multisegmental rotation and temporal coordination of head, trunk, and pelvis while maintaining postural stability of the whole body. Previous research reported that
