Abstract

This experimental evaluation of Cybex II isokinetic measurement was based on 70 normal subjects and 120 patients with chronic low back pain. It considered: reliability and learning effect; discrimination of individual patients versus normal subjects; relationship to clinical measures; assessment of effort; and a prospective 2-year follow-up of normal subjects to predict future low back pain.
