Correlation between hip function and knee kinematics evaluated by three-dimensional motion analysis during lateral and medial side-hopping

Abstract

[Purpose] Kinematic and kinetic characteristics of the limb during side-hopping and hip/knee interaction during this motion have not been clarified. The purposes of this study were to examine the biomechanical parameters of the knee during side hop and analyze its relationship with clinical measurements of hip function. [Subjects and Methods] Eleven male college rugby players were included. A three-dimensional motion analysis system was used to assess motion characteristics of the knee during side hop. In addition, hip range of motion and muscle strength were evaluated. Subsequently, the relationship between knee motion and the clinical parameters of the hip was analyzed. [Results] In the lateral touchdown phase, the knee was positioned in an abducted and externally rotated position, and increasing abduction moment was applied to the knee. An analysis of the interaction between knee motion and hip function showed that range of motion for hip internal rotation was significantly correlated with external rotation angle and external rotation/abduction moments of the knee during the lateral touchdown phase. [Conclusion] Range of motion for hip internal rotation should be taken into consideration for identifying the biomechanical characteristics in the side hop test results.

An investigation into the role of gluteal muscle strength and EMG activity in controlling HIP and knee motion during landing tasks

“…G med EMG activity was associated with knee abduction moment. In the study of Itoh et al, (2016) hip external rotation strength was associated with knee abduction angle and moment, which contrasts with this study's finding, where G med would appear to have a more significant role as opposed to Gmax.…”

“…Hip internal rotation angle was associated with hip abduction concentric strength, hip internal rotation moment was associated with hip abduction and extension eccentric strength and G max EMG activity. Itoh et al, (2016) found a moderate correlation between knee abduction angle and hip internal rotation moment and hip extension strength measured isometrically in male rugby players, which partial supports the current study findings. They also found hip external rotation strength to be correlated with knee abduction angle and moment.…”

“…showed that ICC (1, 1) for samesession data of two trials and ICC (1, 1) for between-day data of two sessions separated by a two-day interval ranged from 0.93-0.96 for measurement of maximal isometric strength of hip muscles of five volunteers. 2) spinous processes of the seventh cervical vertebra, second and seventh thoracic vertebrae, jugular notch, xiphoid process, and the first, third, and fifth lumbar vertebrae, 3) acromion, deltoid tuberosity, lateral humeral epicondyle, dorsal forearm, styloid processes of the ulna and radius and head of the third metacarpal, 4) anterior superior and posterior superior iliac spines, 5) the greater trochanter, the lateral and medial femoral epicondyles, 6) the fibular head, the tibial tuberosity, the lateral and medial malleoli, and 7) proximal posterior surface of the calcaneus and distal attachment of the Achilles tendon on the calcaneus, the sustentaculum tali, the peroneal tubercle, the navicular tuberosity, the first, second and fifth metatarsal heads, proximal distal phalanx, bases of the first and second metatarsals, and styloid process of the fifth metatarsal [31].…”

“…A series of calibration trials in anatomical standing posture was performed to determine anatomical landmarks and lower limb joint coordinate systems [31]. After two practice trials, each participant performed three trials of the drop-landing task.…”

“…Tracking the motions of the markers, sampling, interpolation of missing data, and filtering the raw threedimensional coordinate data were performed as described previously [31]. The joint angles and moments were calculated using the Euler angle method for hip flexion/extension, adduction/abduction, and IR/ER sequences according to the recommendations of the International Society of Biomechanics [34].…”
