OBJECTIVE: To examine the Oxygen Uptake Efficiency Slope (OUES) as an outcome for physical fitness in patients with multiple sclerosis. DESIGN: Cross-sectional study. PATIENTS: A maximal cycling ergometry test was performed by 56 patients with multiple sclerosis. METHODS: The OUES was compared with healthy reference values. Correlation analysis was used to assess the concurrent validity of the OUES and the following commonly used parameters of maximal exercise testing: maximal power output (Wmax) and peak oxygen consumption (VO2peak). The predictive validity of a submaximal OUES, derived using only 50% of the exercise duration (OUES50), and an OUES derived using the full exercise duration (OUES) were determined. RESULTS: The OUES (mean 24.2 (standard deviationDownloads
