The majority of adults with Generalised Joint Hypermobility experience symptoms such as pain and joint instability, which is likely to influence their gait pattern. Accordingly, the purpose of the present project was to perform a biomechanical gait analysis on a group of patients with Generalised Joint Hypermobility and compare them to a group of healthy subjects.
Seventeen adults clinically classified with Generalised Joint Hypermobility (6 males and 11 females) and seventeen healthy subjects (9 males and 8 females) were included in the project. The subjects walked across three force platforms while they were filmed by five video cameras. Net joint moments were calculated in 3D by inverse dynamics and peak values were input to statistical analyses. A 3D knee joint model was used to calculate bone-on-bone forces.
In the frontal plane both the peak knee and hip abductor moments were 13% higher in the patient group. In the sagittal plane the peak knee extensor moment was 10% higher for the patients and the flexor moment about the knee joint in the middle of stance was 27% lower for the patients. Increased flexion in the knee joint for the patients was also observed.
The finding that adults with Generalised Joint Hypermobility display higher joint moments during walking in both the frontal and the sagittal planes and increased knee joint loadings may explain the pain symptoms in the patient group and indicate these subjects are subjected to an increased risk of developing osteo-arthritis.
大多数患有全身关节过度活动综合征的成年人会经历疼痛和关节不稳定等症状，这可能会影响他们的步态模式。因此，本项目的目的是对一组全身关节过度活动综合征患者进行生物力学步态分析，并将他们与一组健康受试者进行比较。
本项目纳入了17名临床诊断为全身关节过度活动综合征的成年人（6名男性和11名女性）以及17名健康受试者（9名男性和8名女性）。受试者在走过三个测力平台时，由五台摄像机进行拍摄。通过逆动力学计算三维净关节力矩，并将峰值输入统计分析。使用三维膝关节模型计算骨间力。
在额状面，患者组的膝关节和髋关节外展肌峰值力矩均高出13%。在矢状面，患者的膝关节伸展肌峰值力矩高出10%，而在站立中期膝关节的屈曲力矩患者组则低27%。还观察到患者膝关节的屈曲增加。
全身关节过度活动综合征的成年人在行走时在额状面和矢状面均表现出更高的关节力矩以及膝关节负荷增加，这一发现可能解释了患者组的疼痛症状，并表明这些受试者患骨关节炎的风险增加。
