An inverse dynamics model for the analysis, reconstruction and prediction of bipedal walking [PDF]

, 1995
Walking is a constrained movement which may best be observed during the double stance phase when both feet contact the floor. When analyzing a measured movement with an inverse dynamics model, a violation of these constrains will always occur due to ...

Passive hallux adduction decreases lateral plantar artery blood flow: a preliminary study of the potential influence of narrow toe box shoes

Journal of Foot and Ankle Research, 2019
Background Blood flow is essential in maintaining tissue health. Thus, compromised blood flow can prevent tissue healing. An adducted hallux, as seen inside a narrow shoe, may put passive tension on the abductor hallucis, compressing the lateral plantar ...

Effect of real‐time biofeedback on peak knee adduction moment in patients with medial knee osteoarthritis: Is direct feedback effective?

Clinical Biomechanics, 2017
Background: Gait modifications can reduce the knee adduction moment, a representation of knee loading. Reduced loading may help to slow progression of medial knee osteoarthritis.

尿素包合法从葡萄籽油中富集高纯度 亚油酸甲酯及包合Enrichment of high purity methyl linoleate from grape seed oil by urea adduction and characterization of adduction complexes物表征分析

Zhongguo youzhi, 2022
为提升葡萄籽的使用价值，以葡萄籽油为原料，采用尿素包合法富集高纯度亚油酸甲酯。研究了脂肪酸甲酯与尿素质量比、尿素与95%乙醇质量比、包合时间和包合温度对包合效果的影响，并采用傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）和扫描电子显微镜（SEM）对空白尿素结晶物和包合固形物进行表征。结果表明：制备高纯度亚油酸甲酯的最佳工艺条件为脂肪酸甲酯与尿素质量比1∶ 2、尿素与95%乙醇质量比1∶ 4、包合温度5 ℃、包合时间10 h，在此条件下得到的亚油酸甲酯含量为94.83%，收率为40.41 ...

Kinematic Foot Types in Youth with Equinovarus Secondary to Hemiplegia [PDF]

, 2015
Background Elevated kinematic variability of the foot and ankle segments exists during gait among individuals with equinovarus secondary to hemiplegic cerebral palsy (CP). Clinicians have previously addressed such variability by developing classification

Altered motor function during daily activities in patients eligible for high tibial osteotomy is primarily driven by knee varus deformity

Bone & Joint Open
Aims: Patients with knee osteoarthritis (OA) and varus deformity present altered gait parameters, especially a large knee adduction moment that is predictive of OA progression.
