PEDro scoring components: 1 = subjects were randomly allocated to groups; 2 = allocation was concealed; 3 = groups were similar at baseline regarding the most important prognostic indicators; 4 = blinding of all subjects; 5 = blinding of all therapists who administered therapy; 6 = blinding of all assessors who measured at least one outcome; 7 = measures of at least one key outcome were obtained from more than 85% of subjects initially allocated to groups; 8 = 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 was analyzed by “intention to treat”; 9 = results of between-group statistical comparisons are reported for at least one key outcome; 10 = study provides both point measures and measures of variability for at least one key outcome.

^*PEDro scores of 5 or greater are considered high methodological quality.
