Clinical TrialReliability and responsiveness of the lower extremity functional scale and the anterior knee pain scale in patients with anterior knee pain.
Prospective methodological study of repeated measures using a sample of consecutive patients. ⋯ The LEFS and the AKPS both demonstrated high test-retest reliability and appear to be moderately responsive to clinical change in patients with anterior knee pain. Reliability and responsiveness were slightly higher in the LEFS than the AKPS. Further research is needed to determine if these measures could be modified, or new measures created, to produce an even more sensitive tool for this population.
