Comparison of Heart Rate Variability and Skin Perfusion in Spinal Cord Injury

This study compares changes in heart rate variability and skin perfusion in response to postural changes between individuals with spinal cord injury and nondisabled controls. Differences in skin perfusion, beat-to-beat heart rate intervals, and heart rate variability are observed during postural adjustments. The findings emphasize the impact of spinal cord injury on autonomic regulation. (291 characters)

  1. Figure 1. Example of changes of skin perfusion, beat-to-beat interval of heart rate (R-R), and heart rate variability (HRV) during postural changes. Skin perfusion shows increase in prone posture in (a) nondisabled control, but not in (b) person with SCI. R-R intervals show increase in (c) nondisabled control, but not in (d) person with SCI. Spectral analysis reveals increase in power of low frequency of HRV in prone posture in (e) nondisabled control, but not in (f) person with SCI. PSD = power spectrum density.
