In children with spastic cerebral palsy (CP), the most common motor dysfunction is pathological gait.
To evaluate the effectiveness of measures for an individual CP case.
The case of one spastic diplegia child has been analyzed. Both lower extremities and spine were examined under three gait conditions: 1) barefoot, 2) with ankle-foot orthoses (AFOs) and thoracolumbosacral spinal orthosis (TLSO), and 3) with TLSO only. Spatiotemporal gait and kinematic parameters of the pelvic, hip, knee, ankle joints, and spine were obtained using Vicon Plug-in-Gait model. The difference (Δ) between the measured values and normative ranges was calculated to determine the efficiency of the orthoses.
Significant differences were found in kinematic and spatiotemporal parameters comparing results between conditions and body sides. The effectiveness of the measures was confirmed by the smallest Δ values in the double and single support time with the AFOs/TLSO and in the stride and stance time with TLSO.
Based on the study results, the best stability of the spine, ankle plantarflexion, and knee hyperextension is achieved with the AFOs/TLSO; therefore, this combination of measures was considered the most effective. However, not only quantitative parameters should be taken into account, but also the child's willingness and comfort.
在痉挛型脑瘫儿童中,最常见的运动功能障碍是病理性步态。
评估针对个体脑瘫病例的措施的有效性。
分析了一例痉挛性双瘫儿童的病例。在三种步态条件下检查了下肢和脊柱:1)赤脚,2)使用踝足矫形器(AFO)和胸腰骶脊柱矫形器(TLSO),3)仅使用 TLSO。使用 Vicon Plug-in-Gait 模型获得骨盆、髋关节、膝关节、踝关节和脊柱的时空步态和运动学参数。通过计算测量值与正常值之间的差异(Δ)来确定矫形器的效率。
在条件和身体侧之间的比较中,发现运动学和时空参数存在显著差异。AFO/TLSO 可减小双支撑和单支撑时间以及 TLSO 可减小步幅和站立时间的Δ值,这证实了措施的有效性。
根据研究结果,AFO/TLSO 可实现脊柱、踝关节跖屈和膝关节过伸的最佳稳定性,因此,这种措施组合被认为是最有效的。然而,不仅要考虑定量参数,还要考虑孩子的意愿和舒适度。
