Overall , the effect of physical interventions on physical performance was inconsistent .
Patient tailored interventions , i.e. continuously adapted to the capabilities of the patient were not found to be superior over interventions that were not .
Conclusions Evidence for the effect of physical interventions on physical performance in older patients during hospitalization was found uncertain .
Background To counteract decline in physical performance and physical activity in older patients during hospitalization , multiple physical interventions were developed .
However , it is unknown whether these are effective in this particular population .
This systematic review aim ed to identify the effect of physical interventions on physical performance and physical activity in older patients during hospitalization .
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
