Combined Home Exercise Is More Effective Than Range-of-Motion Home Exercise in Patients with Ankylosing Spondylitis: A Randomized Controlled Trial

Table 4

Comparison of pulmonary function test at the baseline and after 3-month exercise between combined home exercise (COMB) group and range-of-motion home exercise (ROM) group.

Variables	COMB group ( = 9)			ROM group ( = 10)			Both groups

FVC: forced vital capacity; FEV1: forced expiratory volume at 1 second; PEF: peak expiratory flow; VC: vital capacity; TLC: total lung capacity; RV: residual volume; FRC: functional residual capacity. P values for differences in the baseline data between the COMB and the ROM groups; values for differences in the postexercise data between the COMB and the ROM groups; values for differences in the changed score between the baseline and the postexercise data between the COMB and the ROM groups.
