Characteristics Baseline Stratified blended physiotherapy (n=104) Face-to-face physiotherapy (n=104) Physical functioning (score 0-100), mean (SD) 19.37 (15.64) 20.38 (13.99) Pain intensity (average score 7 days 0-10), mean (SD) 5.61 (1.99) 5.36 (2.01) Physical activity (MVPAb minutes/ day), mean (SD) 80.34 (36.75) 74.82 (40.94) Health-related quality of life (score 0-100), mean (SD) 67.90 (18.08) 69.75 (17.63) Fear-avoidance beliefs (score 0-96), mean (SD) 27.86 (16.03) 25.08 (16.18) Pain catastrophizing (score 0-52), mean (SD) 11.06 (9.30) 10.21 (8.75) Self-efficacy (score 10-40) mean (SD) 32.13 (4.36) 33.12 (3.62) Patient activation (score 0-100), mean (SD) 62.48 (12.38) 64.75 (12.68) aLBP: low back pain. bMVPA: moderate to vigorous physical activity. Number and Treatment Modalities of Physiotherapy Sessions In total, 189 physiotherapist registration forms were returned (n=95, 50.3% stratified blended physiotherapy and n=94, 49.7% in face-to-face physiotherapy). Table 3 shows the number and treatment modalities of the face-to-face physiotherapy sessions. Patients in the stratified blended physiotherapy group received an average of 4.81 (SD 2.94) faceto-face sessions. For the low-, medium-, and high-risk groups, the average number of sessions was 3.77 (SD 2.54), 5.65 (SD 2.65), and 7.67 (SD 3.54), respectively. Patients in the face-to-face physiotherapy group received an average of 4.94 (SD 2.26) face-to-face sessions. The average number of sessions for the low-, medium-, and high-risk groups was 4.88 (SD 2.02), 5.09 (SD 2.51), and 4.33 (SD 4.16), respectively. In general, education was the main treatment modality during the face-to-face sessions in both treatment groups. No remarkable differences in treatment modalities were found between the 2 groups or between the different risk groups of developing persistent LBP.
