Baseline – the measurement before physiotherapy; Post - the measurement after physiotherapy; pa – p-value between baseline and post-physiotherapy within each group; pbp-value between study groups; ESa – effect size (Cohen d) within each group; ESb – effect size (Cohen d) between study groups; p < 0,05; CIa Confidence interval within each group based on means and SD, CIb Confidence interval between study groups based on means and SD.
