Children with cerebral palsy (CP) require individualized long-term management to maintain and improve motor functions. The objective of this study was to explore potential effects of synchronized metronome training (SMT) on movement kinematics in two children diagnosed with spastic hemiplegic CP (HCP).
Both children underwent 4-weeks/12 sessions of SMT by means of the Interactive Metronome (IM). Optoelectronic registrations of goal-directed uni- and bimanual upper-limb movements were made at three occasions; pre-training, post completed training and at 6-months post completed training.
Significant changes in kinematic outcomes following IM training were found for both cases. Findings included smoother and shorter movement trajectories in the bimanual condition, especially for the affected side. In the unimanual condition, Case I also showed increased smoothness of the non-affected side.
The observed short- and long-term effects on the spatio-temporal organization of upper-limb movements need to be corroborated and extended by further case-control studies.
脑瘫（CP）患儿需要个性化的长期管理以维持和改善运动功能。本研究的目的是探讨同步节拍器训练（SMT）对两名痉挛性偏瘫型脑瘫（HCP）患儿运动学的潜在影响。
两名患儿均通过交互式节拍器（IM）接受了为期4周/12节的SMT训练。在三个时间点进行了目标导向的单上肢和双上肢运动的光电记录；训练前、训练结束后以及训练结束后6个月。
两名患儿在接受IM训练后运动学结果均有显著变化。结果包括在双手运动状态下运动轨迹更平滑、更短，尤其是患侧。在单手运动状态下，病例1的非患侧运动平滑度也有所增加。
观察到的对上肢运动时空组织的短期和长期影响需要通过进一步的病例对照研究来证实和扩展。
