“…For each thigh, the Z axis pointed upwards and was aligned with the long axis of the bone, defined from the hip joint centre (predicted from the ASIS and PSIS locations [13,14]) and the midpoint of the knee epicondyles. The X axis pointed right and was perpendicular to the Z axis and in the plane containing the knee epicondyles and hip joint centre and the Y axis was defined as the common perpendicular.…”

“…A dynamic model of the human whole body, consisting of 16 segments (head, thorax, lumbar, pelvis, upper arms, forearms, hands, thighs, shanks, and feet) and 45 degrees of freedom linkages for 15 joints (cervical, thoracic, lumbar, shoulders, elbows, wrists, hips, knees, and ankles), was used as in our previous study [8]. Joint centers were defined based on the previous studies [9,10]. The reference frames of each segment were commonly set [5,6].…”

“…Participants were instructed to stand in an anatomically neutral position to define anatomical markers relative to the dynamic clusters, similarly to the calibrated anatomical-systems technique. 26 A CODA pelvis model (Charnwood Dynamics Ltd, Leicestershire, United Kingdom) was created to estimate hip-joint centers based on the work of Bell et al 27,28 Kneeand ankle-joint centers were defined as the midpoints between the lateral and medial epicondyle markers of the femur and the lateral and medial malleolus markers, respectively. Joint kinematics were calculated using a Cardan-Euler method in which the sequence of rotations was X (sagittal plane), Y (frontal plane), Z (vertical plane).…”

Context: Unilateral body-weight exercises are commonly used to strengthen the lower limbs during rehabilitation after injury, but data comparing the loading of the limbs during these tasks are limited.Objective: To compare joint kinetics and kinematics during 3 commonly used rehabilitation exercises.Design: Descriptive laboratory study. Setting: Laboratory. Patients or Other Participants: A total of 9 men (age ¼ 22.1 6 1.3 years, height ¼ 1.76 6 0.08 m, mass ¼ 80.1 6 12.2 kg) participated.Intervention(s): Participants performed the single-legged squat, forward lunge, and reverse lunge with kinetic data captured via 2 force plates and 3-dimensional kinematic data collected using a motion-capture system.Main Outcome Measure(s): Peak ground reaction forces, maximum joint angles, and peak sagittal-joint moments.Results: We observed greater eccentric and concentric peak vertical ground reaction forces during the single-legged squat than during both lunge variations (P .001). Both lunge variations demonstrated greater knee and hip angles than did the single-legged squat (P , .001), but we observed no differences between lunges (P . .05). Greater dorsiflexion occurred during the single-legged squat than during both lunge variations (P , .05), but we noted no differences between lunge variations (P ¼ .70). Hip-joint moments were greater during the forward lunge than during the reverse lunge (P ¼ .003) and the single-legged squat (P ¼ .011). Knee-joint moments were greater in the single-legged squat than in the reverse lunge (P , .001) but not greater in the single-legged squat than in the forward lunge (P ¼ .41). Ankle-joint moments were greater during the single-legged squat than during the forward lunge (P ¼ .002) and reverse lunge (P , .001).Conclusions: Appropriate loading progressions for the hip should begin with the single-legged squat and progress to the reverse lunge and then the forward lunge. In contrast, loading progressions for the knee and ankle should begin with the reverse lunge and progress to the forward lunge and then the single-legged squat.Key Words: joint moment, peak force, lunge, single-legged squat, loading Key PointsConcentric and eccentric peak vertical ground reaction forces were greater during the single-legged squat than during the reverse and forward lunges because of an increased base of support during the lunges and greater ankleand knee-joint moments. Hip-joint moments were greater in the forward lunge. Peak joint angles were greater in the lunge variations than in the single-legged squat. Practitioners can use this information to develop a progressive loading paradigm for the hip, knee, and ankle during rehabilitation after injury.
