Abstract：
UNASSIGNED: Heart rate variability (HRV) is a biomarker of autonomic nervous system (ANS) reaction in persons with severe acquired brain injury (sABI) who undergo a rehabilitation treatment, such as focal muscle vibration (FMV).This study aims to evaluate if and how FMV can modulate HRV and to compare potential differences in FMV modulation in HRV between patients with sABI and healthy controls.
UNASSIGNED: Ten patients with sABI and seven healthy controls have been recruited. Each individual underwent the same stimulation protocol (four consecutive trains of vibration of 5 minutes each with a 1-minute pause). HRV was analyzed through the ratio of frequency domain heart-rate variability (LF/HF).
UNASSIGNED: In the control group, after performing FMV, a significant LF/HF difference was observed in the in the second vibration session compared to the POST phase. Patients with SABI treated on the affected side showed a statistically significant LF/HF difference in the PRE compared to the first vibration session.
UNASSIGNED: These preliminary results suggest that FMV may modify the cardiac ANS activity in patients with sABI.

摘要：
■心率变异性（HRV）是接受康复治疗的严重获得性脑损伤（sABI）患者的自主神经系统（ANS）反应的生物标志物，如局灶性肌肉振动（FMV）。本研究旨在评估FMV是否以及如何调节HRV，并比较sABI患者和健康对照患者在HRV中FMV调节的潜在差异。
■招募了10名sABI患者和7名健康对照者。每个个体经历相同的刺激方案(四个连续的5分钟的振动序列,每个具有1分钟的暂停)。通过频域心率变异性（LF/HF）的比值分析HRV。
■在对照组中，在执行FMV之后,与POST阶段相比，在第二次振动会话中观察到显着的LF/HF差异。与第一次振动疗程相比，在患侧接受SABI治疗的患者在PRE中显示出统计学上显着的LF/HF差异。
■这些初步结果表明，FMV可能会改变sABI患者的心脏ANS活性。
