摘要
目的:探讨脑瘫(CP)患者和典型发育(TD)患者膝关节伸肌肌肉大小和力量的年龄相关性差异。方法:54例CP患者(14.5±4.5年，GMFCS I-V)和33例TD患者(16.2±5.5年)。采用线性回归和ANCOVA方法检验股直肌(RF)和股外侧肌(VL)肌肉体积和等速膝关节伸肌力量与年龄的关系，以检验组间年龄相关差异。结果:肌肉体积随年龄的线性回归在TD患者中具有统计学意义(VL: r2 = 0.48, RF: r2 = 0.56, p r = 0.36, RF: r2 = 0.27, p p > 0.05)。在TD中观察到与年龄相关的力量差异(r2 = 0.66, p r2 = 0.096, p = 0.024)，但CP和TD之间的斜率有显著差异(p结论:两组在肌肉体积和力量上均观察到与年龄相关的线性差异。与TD患者相比，CP患者的膝关节伸肌力量和力量与体重比的年龄相关差异的线性斜率明显低于TD患者，这表明力量不足以跟上生长过程中体重的增加。
Age-Related Differences in Muscle Size and Strength between Individuals with Cerebral Palsy and Individuals with Typical Development.
Aim: Examine age-related differences in muscle size and strength of the knee extensors in individuals with cerebral palsy (CP) and individuals with typical development (TD).
Methods: 54 individuals with CP (14.5 ± 4.5 years, GMFCS I-V) and 33 individuals with TD (16.2 ± 5.5 years) were included. Relationships between rectus femoris (RF) and vastus lateralis (VL) muscle volume and isokinetic knee extensor strength with age were examined with linear regression and ANCOVA to test age-related differences between groups.
Results: Linear regression for muscle volume with age was statistically significant in TD (VL: r2 = 0.48, RF: r2 = 0.56, p < .05) and those with CP (VL: r = 0.36, RF: r2 = 0.27, p < .05) with no differences in regression slopes between groups (p > .05). Age-related strength differences were observed in TD (r2 = 0.66, p < .001) and those with CP (r2 = 0.096, p = .024), but the slopes were significantly different between CP and TD (p < .001).
Conclusion: Age-related linear differences in muscle volume and strength were observed in both groups. The linear slope of the age-related differences in knee extensor muscle strength and strength-to-body mass ratio were significantly lower in individuals with CP compared to individuals with TD, suggesting that strength is insufficient to keep up with gains in body mass during growth.
