Abstract
BackgroundTechnological development and improvements in Wearable Physiological Monitoring devices, have facilitated the wireless and continuous field-based monitoring/capturing of physiologic measures in healthy, clinical or athletic populations. These devices have many applications for prevention and rehabilitation of musculoskeletal disorders, assuming reliable and valid data is collected. The purpose of this study was to appraise the quality and synthesize findings from published studies on psychometric properties of heart rate measurements taken with the Zephyr Bioharness device.MethodsWe searched the Embase, Medline, PsycInfo, PuMed and Google Scholar databases to identify articles. Articles were appraised for quality using a structured clinical measurement specific appraisal tool. Two raters evaluated the quality and conducted data extraction. We extracted data on the reliability (intra-class correlation coefficients and standard error of measurement) and validity measures (Pearson/Spearman’s correlation coefficients) along with mean differences. Agreement parameters were summarised by the average biases and 95% limits of agreement.ResultsA total of ten studies were included: quality ratings ranged from 54 to 92%. The intra-class correlation coefficients reported ranged from 0.85–0.98. The construct validity coefficients compared against gold standard calibrations or other commercially used devices, ranged from 0.74–0.99 and 0.67–0.98 respectively. Zephyr Bioharness agreement error ranged from − 4.81 (under-estimation) to 3.00 (over-estimation) beats per minute, with varying 95% limits of agreement, when compared with gold standard measures.ConclusionGood to excellent quality evidence from ten studies suggested that the Zephyr Bioharness device can provide reliable and valid measurements of heart rate across multiple contexts, and that it displayed good agreements vs. gold standard comparators – supporting criterion validity.

Search To identify articles on psychometric properties of Zephyr Bioharness device, we searched the Embase, Medline, PsycInfo, PuMed and Google Scholar databases between January 2010 – January 2017, using the following keywords: Zephyr Bioharness OR Zephyr bioharness (ZB)) AND
Zephyr bioharness heart rate validity We identified two studies that assessed the validity of ZB heart rate variable against other commercially used devices (Polar T31) [1, 24], and six studies that assessed validity against gold standard criterion measure (ECG) [Table 4] [22, 25,26,27,28,29]
Summary
Technological development and improvements in Wearable Physiological Monitoring devices, have facilitated the wireless and continuous field-based monitoring/capturing of physiologic measures in healthy, clinical or athletic populations. These devices have many applications for prevention and rehabilitation of musculoskeletal disorders, assuming reliable and valid data is collected. Technological development and improvements in Wearable Physiological Monitoring (WPM) devices, have facilitated the wireless, long range and continuous field-based monitoring/capturing of physiologic measures in healthy, clinical or athletic populations [1,2,3]. It has been proposed that heart rate measures can be used to provide an estimate of energy expenditure, providing an easier and inexpensive alternative [12]
