Sixty-two participants (53% female) with a mean age of 45 (SD 14) years completed the study; there were 31 participants with axSpA (42% female, 54 (SD 13) years old) and 31 non-back pain participants (65% female, 36 (SD 10) years old). The axSpA group had more functional limitation, higher disability and a slower walking speed compared to the non-back pain group (Table 2). The axSpA group demonstrated more limited range of motion in the lumbar, shoulder and hip joints, and increased thoracic kyphosis and forward head posture compared to the non-back pain group (Table 3).
