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.

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).
