Physical capacity tasks in chronic low back pain: what is the contributing role of cardiovascular capacity, pain and psychological factors?
To explore the association of personal and body functions with physical capacity tasks used in the evaluation of chronic low back pain (CLBP) treatment. ⋯ Cardiovascular capacity, pain intensity, fear of injury/movement, cognitions, and depression had statistically significant but clinically minor effects on several, but not all capacity tasks. Radiating pain, age and duration of complaints had no significant influence at all. Due to anthropometric differences men outperformed women on most tasks. Apparently the influence of many personal, physical but especially psychological factors on the selected capacity tasks is not high at all. This might indicate that these tasks are more objectively measuring physical capacity than expected.
