PURPOSE: To determine the intra- and inter-session reliability of balance
performance in people with patellofemoral pain syndrome (PFPS) and matched
controls. METHODS: In this methodological study, single-leg-stance performance of
15 participants with unilateral PFPS and 15 healthy matched controls was assessed
using the Biodex Balance System (BBS) under 4 task difficulty levels (static and
dynamic, with and without visual feedback). Intra-class correlation coefficients
(ICCs), standard errors of measurement, and coefficients of variation were
calculated for the overall stability index, anterior-posterior stability index,
and medial-lateral stability index. RESULTS: Static and dynamic postural
performance during single-leg stance showed moderate to very high reliability in the PFPS group (ICCs=0.53-0.96) and in healthy control participants
(ICCs=0.51-0.91). Both measures were more reliable with eyes closed than with
eyes open. CONCLUSION : BBS stability indices appear to have acceptable
reliability in people with PFPS, particularly in more challenging conditions, and
may be incorporated into the evaluation and rehabilitation of this patient group.
