It has been highlighted that obesity influences the gait reducing walking velocity, stride length, ankle dorsal flexion at initial contact and ankle power generation. Meanwhile, step width, double support, hip flexion, knee extension during stance, hip moment and ankle power absorption was described increased. A tendency to the normalization of these parameters occur when subjects reduced their weight during growth.
We studied the effect of fast weight loss due to Sleeve Gastrectomy on gait pattern of adolescent with severe obesity. The aim is to assess the functional benefit of the surgery.
Pediatric hospital, public health, Italy.
11 patients before and after 1 year from surgery and 10 controls participated to the study. We studied the gait with an optoelectronic system and two force plates. We evaluated both kinetics and kinematics of walking. Then we looked at the differences between the pre- vs post-surgery and with the control group.
Step length and velocity were lower and step width was bigger in adolescent with obesity. Kinematic and kinetic parameters were altered. After surgery we observed the reduction of several gait alteration. Meanwhile, after 1 year alterations at the level of the foot, the knee and the pelvis persist.
The sudden loss of weight highlighted the presence of long-term effects on the locomotor system. The results discourage intense walking activities before the weight loss and we suggest further studies for evaluating the necessity of a rehabilitative intervention.
肥胖会影响步态，降低步行速度、步幅、初始接触时的踝关节背屈和踝关节功率输出。同时，描述了步宽、双支撑、站立时的髋关节屈曲、膝关节伸展、髋关节力矩和踝关节吸收功率增加。当受试者在生长过程中减轻体重时，这些参数有趋于正常的趋势。
我们研究了由于袖状胃切除术导致的快速体重减轻对严重肥胖青少年步态模式的影响。目的是评估手术的功能益处。
意大利一家儿科医院，公共卫生。
11 名患者在手术后 1 年和 10 名对照者参与了这项研究。我们使用光电系统和两个测力板研究了步态。我们评估了步行的运动学和动力学。然后我们比较了术前与术后以及与对照组之间的差异。
肥胖青少年的步幅和速度较低，步宽较大。运动学和动力学参数发生了改变。手术后，我们观察到一些步态异常的减少。然而，一年后，脚部、膝盖和骨盆仍存在异常。
体重的突然减轻突出了对运动系统的长期影响。这些结果不鼓励在体重减轻前进行剧烈的步行活动，我们建议进一步研究评估康复干预的必要性。
