Abstract

Background/purpose: 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.

Methods: 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).

Results: 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.

Conclusion: These preliminary results suggest that FMV may modify the cardiac ANS activity in patients with sABI.

重度后天性脑损伤患者局灶性肌肉振动引起的心率变异性改变。

背景/目的：心率变异性（HRV）是重度后天性脑损伤（sABI）患者接受康复治疗（如局灶性肌肉振动（FMV））时自律神经系统（ANS）反应的生物标志物。本研究旨在评估 FMV 是否以及如何调节 HRV，并比较 FMV 对 sABI 患者和健康对照组 HRV 调节的潜在差异：方法：招募了 10 名 sABI 患者和 7 名健康对照者。每个人都接受了相同的刺激方案（四次连续的振动训练，每次 5 分钟，停顿 1 分钟）。通过频域心率变异比（LF/HF）分析心率变异：结果：在对照组中，进行 FMV 治疗后，与治疗前阶段相比，第二次振动治疗的 LF/HF 有显著差异。在患侧接受治疗的 SABI 患者在 PRE 阶段与第一次振动阶段相比，LF/HF 差异具有统计学意义：这些初步结果表明，调频振动可改变 SABI 患者的心脏自律神经系统活动。
