There was no significant between group difference in six-minute walk test distance .
Conclusions Our meta- analysis showed WPAM with exercise prescription or advice are superior to no device in improving CRF in the maintenance phase of CR and no cardiac adverse events were reported with WPAM use .
Our qualitative analysis showed evidence in favour of WPAM with exercise prescription or advice for both CRF and step count .
WPAM with exercise prescription or advice did not change sedentary time .
Background Physical activity ( PA ) is a component of cardiac rehabilitation ( CR ) .
However , life-long engagement in PA is required to maintain benefits gained .
Wearable PA monitoring devices ( WPAM ) are thought to increase PA .
There appear to be no review s which investigate the effect of WPAM in cardiac population s. We firstly aim ed to systematic ally review r and omised controlled trials within the cardiac population that investigated the effect WPAM had through the maintenance phase of CR .
We specifically examined the effect on cardiorespiratory fitness ( CRF ) , amount and intensity of daily PA , and sedentary time .
The PEDro scale is a valid measure of the methodological quality of clinical trials: a demographic study.
QUESTIONS Does the PEDro scale measure only one construct ie , the method ological quality of clinical trials ? What is the hierarchy of items of the PEDro scale from least to most adhered to ? Is there any effect of year of publication of trials on item adherence ? Are PEDro scale ordinal scores equivalent to interval data ? DESIGN Rasch analysis of two independent sample s of 100 clinical trials from the PEDro data base scored using the PEDro scale . RESULTS Both sample s of PEDro data showed fit to the Rasch model with no item misfit . The  PEDro scale item hierarchy was the same in both sample s , ranging from the most adhered to item r and om allocation , to the least adhered to item therapist blinding . There was no differential item functioning by year of publication . Original PEDro ordinal scores were highly correlated with transformed PEDro interval scores ( r = 0.99 ) . CONCLUSION The PEDro scale is a valid measure of the method ological quality of clinical trials . It is valid to sum PEDro scale item scores to obtain a total score that can be treated as interval level measurement and subjected to parametric statistical analysis
