This study helps to explain the clinical observation that insertion of a strutted intradiscal spacer following discectomy reduces reherniation rate by mechanically limiting the increase in RoM and disc height loss following lumbar discectomy ..read more

These findings suggest that contractures in children with cerebral palsy stabilize the ankle during toe walking. Younger children may show greater stability due to early contracture development, while advanced contractures in older children may reduce stability ..read more

Our current findings identified moderate negative correlations between the normalized mass to body mass of abductor pollicis longus and opponens pollicis for both Eaton-Glickel osteoarthritis grade and trapeziometacarpal index, which would support the current hand therapy exercise recommendations for the arthritic trapeziometacarpal population. Caution must be taken in the interpretation of correlations with articular zones degradation as our analytical power was reduced by the complete eburnation of few articular surfaces ..read more

A weakness in the hip abductors severely affected stair climbing performance. Those who managed to complete the task demonstrated abnormal kinematics, reduced joint reaction forces, and poorer dynamic balance ..read more

Migration patterns for both bicruciate-retaining components generally stabilized from 2 to 7.5 years postoperatively, although some outliers show migration of >0.2 mm. Given the high frequency of device-related adverse events and potential healthy survivor bias, these findings do not support the routine clinical use of this implant ..read more

These findings support the use of linear acceleration, derived from wireless inertial measurement units, to supplement detection strategies of high knee abduction moment during athletic tasks in youth athletes after anterior cruciate ligament reconstruction ..read more

Intact-side load carriage may be more clinically beneficial for mitigating the risk of increased intact limb knee loading. Further, load carriage strategy affects intact limb knee loading more than specific prosthetic foot type. These biomechanical findings can help guide rehabilitative load carriage strategies to minimize the elevated risk of knee osteoarthritis in individuals with transtibial amputation ..read more

Our study showed two statistically detectable migration trends which were associated with tibial component aseptic loosening. Although we were unable to assess in this study whether focusing on migration patterns in these directions provides greater predictive value than using Maximum Total Point Motion, the results suggest that certain migration mechanisms are more prevalent than others, which could motivate further research into the causes of such migration patterns ..read more

Following a simulated fall, older adults with knee osteoarthritis showed greater knee flexion at first contact which might suggest inability to resist forwards motion of the body.The more extended hip in this group and the resulting compensation of the upper body posture may lead to no difference in number of steps taken when compared to controls ..read more
