This experimental evaluation of Cybex II isokinetic measurement was ba
sed on 70 normal subjects and 120 patients with chronic low back pain.
It considered: reliability and learning effect; discrimination of ind
ividual patients versus normal subjects; relationship to clinical meas
ures; assessment of effort; and a prospective 2-year follow-up or norm
al subjects to predict future low back pain.
