“…While a high correlation between PRV and HRV was found, the Bland–Altman analyses showed an insufficient to moderate agreement between these measures with PRV consistently reporting higher values compared to HRV. Similar findings have been reported in independent studies (Chen et al, 2021; Henrique Rufino Batista et al, 2021). Batista et al (2021) compared PRV (measured by smartphone (HRV‐4 training™ mobile app)) and HRV (measured by a Polar H10 chest strap) in adults with SCI (C4‐L1, both incomplete and complete), under resting supine conditions.…”

“…Nevertheless, these measures are often highly correlated across tasks (Kunkels et al, 2021;Menghini et al, 2019) and disease states (Chen et al, 2021;Vasconcellos et al, 2015), suggesting that PRV and HRV may have sufficient concurrent validity. The only study involving a SCI population conducted by Batista et al (2021), showed similar findings under resting conditions, that is, PRV (measured by smartphone (HRV-4 training™ mobile app)) and HRV (measured by a Polar H10 chest strap) showed insufficient agreement yet were highly correlated. Given the important clinical ramifications in SCI, research is needed to clarify whether PRV is a valid alternative to HRV that can be used to monitor autonomic function in an SCI population, during both resting states and a reactivity task, and whether results would differ in an able-bodied population.…”

“…We hypothesized that: (i) PRV will demonstrate poor agreement but sufficient concurrent validity (high correlation) with HRV. These relationships will be weaker following the OSLER task and in the SCI population, especially in the SCI‐H group (Henrique Rufino Batista et al, 2021; Menghini et al, 2019). (ii) PRV and HRV will show similar relationship patterns with psychosocial outcomes for the three groups.…”

Pulse rate variability: An alternative to heart rate variability in adults with spinal cord injury

et al. 2023

Pulse rate variability (PRV) is often used as an alternative to heart rate variability (HRV) to measure psychophysiological function. However, its validity to do so is unclear, especially in adults with spinal cord injury (SCI). This study compared PRV and HRV in adults with higher‐level SCI (SCI‐H, n = 23), lower‐level SCI (SCI‐L, n = 22), and able‐bodied participants (AB n = 44), in a seated position as a function of performance in a reactivity task (Oxford Sleep Resistance Test: OSLER). PRV and HRV was measured using reflective finger‐based photoplethysmography (PPG) and electrocardiography, respectively, at baseline, immediately post‐OSLER, and after five‐minute recovery. Agreement between PRV and HRV was determined by Bland–Altman analysis and differences between PRV and HRV over time by linear mixed effects model (LMM) analysis. Concurrent validity was assessed through correlation analyses between PRV and HRV. Additional correlation analyses were performed with psychosocial factors. Results indicated insufficient to moderate agreement between PRV and HRV. LMM analyses indicated no differences over time for standard deviation of normal‐to‐normal intervals and low‐frequency power but significant differences for root mean square of successive differences and high frequency power. Nevertheless, PRV and HRV were highly correlated (Median r = .878 (.675–.990)) during all assessment periods suggesting sufficient concurrent validity. Similar correlation patterns were also found for PRV and HRV with psychosocial outcomes. While differences existed, results suggest PRV derived from reflective finger‐based PPG is a valid proxy of HRV in tracking psychophysiological function in adults with SCI and could therefore be used as a more accessible monitoring tool.
