The mean range of movement scores and standard deviation—landmark versus CT guided injection
| Outcome measurement (max score–degrees*) | Week 0 Landmark (n = 40) CT guided (n = 37) | Week 1 Landmark (n = 39) CT guided (n = 34) | Week 4 Landmark (n = 37) CT guided (n = 35) | Week 12 Landmark (n = 36) CT guided (n = 33) | ||||
|---|---|---|---|---|---|---|---|---|
| Mean | SD | Mean | SD | Mean | SD | Mean | SD | |
| *All scores measured in degrees with the exception of hand behind back scores. This movement is measured on an interval scale where each progression of the thumb up a spinal vertebrae is one unit. | ||||||||
