| Usability outcomes Mean (SD) | At study end (N = 300) | 4 weeks (N = 300) | 8 weeks (N = 300) | 12 weeks (N = 211) |
|---|---|---|---|---|
| Total number of sessions | – | 13.9 (5.92) | 25.6 (11.27)# | 34.7 (17.29) |
| Total exercising time, minutes | – | 231.9 (105.37) | 422.9 (198.41)# | 555.9 (284.10) |
| Number of sessions per week | 3.2 (1.29) | 3.6 (1.42) | 3.4 (1.33)# | 3.2 (1.32) |
| Average pain during sessions (NRS, 0–10) | 1.4 (0.92) | 1.7 (1.06) | 1.5 (0.97)# | 1.4 (0.94) |
| Average fatigue during sessions (NRS, 0–10) | 1.2 (1.09) | 1.3 (1.24) | 1.3 (1.15)# | 1.2 (1.05) |
| Average satisfaction (NRS, 0–10) | 8.7 (1.26) | 8.7 (1.26) | 8.8 (1.18)# | 8.8 (1.21) |

#Estimates at 8 weeks were significantly different from those at 4 weeks as per the paired samples t-test, P < 0.001 for average pain and P = 0.003 for average fatigue
