Findings on the quality of the studies using the Physiotherapy Evidence Database (PEDro) coding scheme (12 studies)^*

	PEDro coding scheme†
1. Eligibility criteria were specified	12
2. Subjects were randomly allocated to groups (in a crossover study, subjects were randomly allocated an order in which treatments were received)	11
3. The groups were similar at baseline regarding the most important prognostic indicators	2
4. Measures of at least one key outcome were obtained from >85% of the subjects initially allocated to groups	11
5. All subjects for whom outcome measures were available received the treatment or control condition as allocated or, where this was not the case, data for at least one key outcome were analyzed by “intention to treat”	12
6. The results of between-group statistical comparisons are reported for at least one key outcome	12
7. The study provides both point measures and measures of variability for at least one key outcome	9
8. The study had an adequate treatment fidelity protocol, including manualized intervention and monitoring of treatment implementation	2
9. Loss to follow-up information is provided	7
