“…Specifically, DF uses anatomical landmarks visible on three‐dimensional CT reconstructions, whereas traditional motion capture methods calculate a coordinate system according to the spatial position of markers adhered to the skin; as we showed, this approach can produce errors in the estimation of the hip joint center that exceeds 20 mm . Further, soft tissue artifact can cause erroneous measurements of hip joint kinematics during dynamic loading for all anatomic planes, including rotation about the sagittal and coronal plane . It has also been shown that participant‐specific pelvic bony anatomy is necessary to measure in vivo pelvic tilt accurately .…”

“…These control participants had no history of hip pain. Controls were screened with an anterior‐posterior (AP) radiograph prior to study inclusion . The AP radiograph provided general screening of hip pathology, including acetabular dysplasia, Legg–Calvé–Perthes disease, and acetabular retroversion.…”

“…For each activity, two trials were captured when possible, but activity level, allotted DF time, and image quality limited the ability to capture and analyze activities from some participants (Table ). For the walking trials at a self‐selected speed, the same treadmill speed was used for level and incline walking trials based on the preferred walking speed of the participant . For all walking trails, a single gait cycle was evaluated.…”

“…For this study, kinematic data were presented as raw joint angles between the local coordinate systems of the femur and the pelvis as well as angles relative to the standing position. Representation of hip kinematics relative to the standing position was considered so as to minimize the effect of anatomic variability on kinematic calculations; this is a reasonable approach given that model‐based markerless tracking of DF images represents kinematic motion relative to the underlying hip anatomy from reconstructed CT images . This approach provided data on both in vivo joint motion and the relative relationship between static (i.e., standing) and dynamic motions.…”

“…We previously developed and validated a dual fluoroscopy (DF) system to quantify in vivo hip arthrokinematics, and found it to be accurate within 0.5 mm and 0.6° . DF has been used to measure arthrokinematics during clinical exams for patients with FAIS and during weight‐bearing activities of daily living for control participants . However, this technology has not been applied to compare hip arthrokinematics between patients with cam FAIS and controls during weight‐bearing activities.…”

Femoroacetabular impingement syndrome (FAIS) may alter the kinematic function of the hip, resulting in pain and tissue damage. Previous motion analysis studies of FAIS have employed skin markers, which are prone to soft tissue artifact and inaccurate calculation of the hip joint center. This may explain why the evidence linking FAIS with deleterious kinematics is contradictory. The purpose of this study was to employ dual fluoroscopy (DF) to quantify in vivo kinematics of patients with cam FAIS relative to asymptomatic, morphologically normal control participants during various activities. Eleven asymptomatic, morphologically normal controls and seven patients with cam FAIS were imaged with DF during standing, level walking, incline walking, and functional range of motion activities. Model‐based tracking calculated the kinematic position of the hip by registering projections of three‐dimensional computed tomography models with DF images. Patients with FAIS stood with their hip extended (mean [95% confidence interval], −2.2 [−7.4, 3.1]°, flexion positive), whereas controls were flexed (5.3 [2.6, 8.0]°; p = 0.013). Male patients with cam FAIS had less peak internal rotation than the male control participants during self‐selected speed level‐walking (−0.2 [−6.5, 6.1]° vs. −9.8 [−12.2, −7.3]°; p = 0.007) and less anterior pelvic tilt at heel‐strike of incline (5°) walking (3.4 [−1.0, −7.9]° vs. 9.8 [6.4, 13.2]°; p = 0.032). Even during submaximal range of motion activities, such as incline walking, patients may alter pelvic motion to avoid positions that approximate the cam lesion and the acetabular labrum. © 2019 Orthopaedic Research Society.

ObjectivesMuscle activity during crouched walking has been previously studied in the context of the evolution of hominin bipedalism and human movement disorders. However, crouched walking could also be used in approach hunting where postural height (actual height of the body from the ground to the top of the head during locomotion) is the limiting factor. Here, we aim to analyze the relationship between relative postural height (%stature), kinematics, and muscle activity during crouched walking.Materials and MethodsAdult males (n = 19) walked with extended limbs and at three degrees of crouch while their 3D motion capture kinematics and lower limb muscle electromyography were recorded. We measured activation of tibialis anterior, soleus, gastrocnemius medialis, gastrocnemius lateralis, vastus lateralis, rectus femoris, biceps femoris, and gluteus maximus. We analyzed the effects of postural height on kinematics and muscle activation using linear mixed effects model.ResultsFlexion angles, individual muscle activation (except for medial gastrocnemius), and total muscle activation were negatively related to relative postural height, that is, were greater at more crouched postures. Relative postural height had a stronger effect on the activation of the thigh and gluteal muscles compared to shank muscles.DiscussionGeneral increase in lower limb muscle activation at lower postural heights suggests a negative relationship between relative postural height and fatigue, and may indicate a possible mechanism by which short stature could benefit the hunter in approach hunting. Greater activation of thigh and gluteal muscles relative to shank muscles may help to identify crouched walking in past human populations.

Three‐dimensional femoral head coverage in the standing position represents that measured in vivo during gait

Individuals with over- or under-covered hips may develop hip osteoarthritis. Femoral head coverage is typically evaluated using radiographs, and/or computed tomography (CT) or magnetic resonance images obtained supine. Yet, these static assessments of coverage may not provide accurate information regarding the dynamic, three-dimensional (3-D) relationship between the femoral head and acetabulum. The objectives of this study were to: (1) quantify total and regional 3-D femoral head coverage in a standing position and during gait, and (2) quantify the relationship between 3-D femoral head coverage in standing to that measured during gait. The kinematic position of the hip during standing and gait was measured in vivo for 11 asymptomatic morphologically normal subjects using dual fluoroscopy and model-based tracking of 3-D CT models. Percent coverage in the standing position and during gait was measured overall and on a regional basis (anterior, superior, posterior, inferior). Coverage in standing was correlated with that measured during gait. For total coverage, very little change in coverage occurred during gait (range: 35.0-36.7%; mean: 36.2%). Coverage at each time point of gait strongly correlated with coverage during standing (r = 0.929-0.989). The regions thought to play an important role in weight bearing (i.e. anterior, superior, posterior) were significantly correlated with coverage in standing during the stance phase. Our results suggest that coverage measured in a standing position is a good surrogate for coverage measured during gait. Clin. Anat. 9999:1-7, 2018. © 2018 Wiley Periodicals, Inc.
