Abstract

Objective: To investigate whether the impacts of height increase on gastrocnemius muscle (GM) stiffness are greater in children with spastic cerebral palsy (CP) than in those with typical development (TD).

Design: This one-year cohort study enrolled children (CP, 23; TD, 23) who underwent two measurements conducted at entry and after one year. Lateral and medial GM-strain ratios representing muscle stiffness were obtained using elastography.

Results: All regression equations (dependent variable, rate of change [RoC] of height; independent variable, RoC of the GM-strain ratios) were significant and all R2s in children with CP (all p < 0.001; lateral GM's R2 = 0.81; medial GM's R2 = 0.74) were greater than those in children with TD (p < 0.001 and R2 = 0.49; medial GM's R2 = 0.49). The coefficients of equations in children with CP were significantly larger than those in TD (p < 0.05).

Conclusion: The greater R2 values in CP than TD could explain how the variation in height predicts the variations in GM stiffness more accurately in CP than in TD. GM stiffness worsens more in children with CP than that in TD.

身高增加对脑瘫患儿腓肠肌僵硬的影响:一项为期一年的前瞻性队列研究。
目的:探讨身高增高对痉挛性脑瘫(CP)患儿腓肠肌(GM)僵硬度的影响是否大于典型发育(TD)患儿。设计:这项为期一年的队列研究招募了儿童(CP, 23;她在入职时和一年后接受了两次测量。通过弹性成像获得代表肌肉刚度的外侧和内侧gm -应变比。结果:所有回归方程(因变量,身高变化率[RoC];自变量(GM-strain ratio的RoC)和CP患儿的R2s均有统计学意义(均p < 0.001;侧位GM的R2 = 0.81;内侧GM (R2 = 0.74)大于TD患儿(p < 0.001, R2 = 0.49;内侧GM的R2 = 0.49)。CP患儿的方程系数显著大于TD患儿(p < 0.05)。结论:CP比TD的R2值更大,可以解释为什么CP比TD的身高变化更准确地预测GM刚度的变化。CP患儿的GM僵硬程度比TD患儿更严重。

期刊介绍: American Journal of Physical Medicine & Rehabilitation focuses on the practice, research and educational aspects of physical medicine and rehabilitation. Monthly issues keep physiatrists up-to-date on the optimal functional restoration of patients with disabilities, physical treatment of neuromuscular impairments, the development of new rehabilitative technologies, and the use of electrodiagnostic studies. The Journal publishes cutting-edge basic and clinical research, clinical case reports and in-depth topical reviews of interest to rehabilitation professionals. Topics include prevention, diagnosis, treatment, and rehabilitation of musculoskeletal conditions, brain injury, spinal cord injury, cardiopulmonary disease, trauma, acute and chronic pain, amputation, prosthetics and orthotics, mobility, gait, and pediatrics as well as areas related to education and administration. Other important areas of interest include cancer rehabilitation, aging, and exercise. The Journal has recently published a series of articles on the topic of outcomes research. This well-established journal is the official scholarly publication of the Association of Academic Physiatrists (AAP).
