Inadequate knowledge in the recruitment patterns of abdominal muscles in individuals with spastic-type cerebral palsy (STCP).
To determine whether there is any difference between the neuromuscular activity (activation pattern) of the abdominal muscles in children with STCP and those of their typically developing (TD) peers.
The NORAXAN electromyography (EMG) was used to monitor the neuromuscular activity in abdominal muscles of individuals with STCP ( = 63), and the results were compared with the findings from age-matched TD individuals ( = 82).
EMG frequencies were recorded during rest and during active states and compared using repeated measures ANOVA. Spearman's rank order correlation was used to explore relationships between age, body mass index and abdominal muscle activity. With the exception of the rectus abdominis (RA) muscle, the pattern of neuromuscular activity in children with STCP differs significantly from that of their TD peers. Three of the muscles - external oblique abdominis (EO), internal oblique abdominis (IO) and RA - in both groups showed significant changes ( < 0.001) in the frequency of EMG activity between the resting and active states. An elevated EMG activity at rest in the EO and IO was recorded in the STCP group, whereas the RA during resting and active stages showed similar results to TD individuals.
The findings from this study suggest that the RA could be targeted during rehabilitation regimens; however, the force generated by this muscle may not be sufficient for the maintenance of trunk stability without optimal support from the EO and IO muscles.
对痉挛型脑瘫（STCP）患者腹部肌肉募集模式的了解不足。
确定STCP患儿与发育正常（TD）同龄人腹部肌肉的神经肌肉活动（激活模式）是否存在差异。
使用NORAXAN肌电图（EMG）监测63例STCP患者腹部肌肉的神经肌肉活动，并将结果与年龄匹配的TD个体（82例）的结果进行比较。
在休息和活动状态下记录EMG频率，并使用重复测量方差分析进行比较。使用Spearman等级相关分析年龄、体重指数与腹部肌肉活动之间的关系。除腹直肌（RA）外，STCP患儿的神经肌肉活动模式与TD同龄人有显著差异。两组中的三块肌肉——腹外斜肌（EO）、腹内斜肌（IO）和RA——在休息和活动状态之间的EMG活动频率均有显著变化（P<0.001）。STCP组记录到EO和IO在休息时EMG活动升高，而RA在休息和活动阶段的结果与TD个体相似。
本研究结果表明，在康复方案中可以针对RA；然而，如果没有EO和IO肌肉的最佳支持，该肌肉产生的力量可能不足以维持躯干稳定性。
