Does yoga improve heart rate variability and autonomic balance in patients with chronic low back pain?
Absolute Event Rate: 49.2% vs 41.3%
p-value: p=0.049
A 3-month yoga intervention in patients with chronic low back pain significantly shifted autonomic balance towards vagal dominance, as evidenced by improved heart rate variability metrics.
Telles et al. (2016) conducted an RCT in chronic low back pain associated with altered alignment of intervertebral discs (n=62). Yoga vs. Standard medical care was evaluated on High frequency (HF) power of heart rate variability (normalized units) (95% CI -0.026, -13.851, p=0.049). Three months of yoga practice significantly increased high-frequency power of heart rate variability and decreased low-frequency power and respiration rate in patients with chronic low back pain.
