Objective To investigate the agreement between lower limb volume measurements for the vertically oriented perometer and a tape measure method. Design Between-methods agreement and testretest reliability study. Setting University setting. Participants Thirty university staff and students were recruited using convenience sampling with no participant drop-outs. Interventions All participants dominant lower limb volumes were measured using the vertically oriented perometer and a tape measure method. Main outcome measures The BlandAltman difference plot was reported for determining the bias between the two methods and its 95% confidence interval. Testretest reliability and the measurement error for the perometer method were determined using the ICC(2,1) model and within-subject standard deviation (sw) respectively. Results There was a lack of agreement between the tape measure and perometer method. The BlandAltman difference plot showed that the tape measure method overestimated limb volume by 157 ml compared to the perometer method. A 95% confidence interval of −834 ml to 519 ml was observed. The testretest reliability of the perometer method was ICC(2,1) = 0.99. The measurement error of the perometer method was clinically acceptable (sw = 121 ml). Conclusions There was a lack of agreement between the two methods investigated. Therefore the perometer and tape measure methods are not interchangeable. It is recommended that future validity and reliability studies for the vertically oriented perometer are conducted on clinical populations. Abbreviations ICC, intraclass correlation; sw, within subject standard deviation (measurement error); CV, coefficient of variation |
