The purpose of this study was to determine the reliability and validity of measuring the anaerobic threshold (AT) in patients with impairments of the lower extremities. The subjects were 20 patients with spinal cord injury (SCI), 14 patients with lower limb amputation (AMP), and 29 patients with orthopedic disease (ORTH). An arm crank ergometer (ACE) was used to establish the AT and peak oxygen uptake (VO2Peak). Each subject was tested twice within 3 weeks to measure test-retest reliability. Test-retest reliability was assessed by intraclass correlation coefficient (ICC). The validity of AT was assessed using the relationship between AT and VO2Peak based on Pearson's correlation coefficient (PCC). ICC values were 0.877 in SCI, 0.939 in AMP and 0.937 in ORTH, and ICC was good to excellent in all groups. PCC values between the AT and VO2Peak were 0.748 in SCI, 0.762 in AMP, and 0.706 in ORTH. These results suggest that the AT as measured ACE, is useful for evaluating the physical fitness of patients with impairments of the lower extremities.
