1 = criterion was satisfied, 0 = criterion was not satisfied. Each satisfied criterion measure, excluding item 1 and 6, contributes 1 point to the total PEDro score (1–9). Criteria: (1) eligibility criteria were specified (^anot applicable); (2) random allocation; (3) concealed allocation; (4) groups similar at baseline; (5) blinding of participants; (6) blinding of therapists who administered the therapy (^anot applicable); (7) blinding of assessors; (8) less than 15% drop-outs; (9) intention to treat; (10) between-group statistical analysis; (11) point measures and variability data.
