PURPOSE: To investigate the correlation between single limb support (SLS) phase
(% of gait cycle) and the Western Ontario and McMaster University Osteoarthritis
Index (WOMAC) questionnaire and Medical Outcomes Study 36-Item Short-Form Health
Survey (SF-36 Health Survey) in patients with knee osteoarthritis (OA). METHOD: A
prospective observational study was employed with 125 adults with bilateral
medial compartment symptomatic knee OA who underwent a physical and radiographic
evaluation. Velocity, step length and SLS were assessed by a computerised mat
(GAITRite). Patients completed the WOMAC and SF-36 Health Survey questionnaires.
RESULTS: Statistical analysis examined the correlations between SLS and both
questionnaires, between Kellgren & Lawrence (K&L) scores and both questionnaires
and between SLS correlations and K&L correlations. We found significantly
stronger correlations between SLS and WOMAC-pain, WOMAC-function, the SF-36 pain
sub-category, velocity and step length than between K&L scores and these
parameters (Pearson's r = 0.50 vs. 0.26, 0.53 vs. 0.34, 0.50 vs. 023, 0.81 vs.
0.33, 0.77 vs. 0.37, respectively; all p < 0.05). Significant differences in SLS
were found over WOMAC-pain, WOMAC-function and SF-36 overall score quartiles (p <
0.05 for all). CONCLUSION: We recommend integrating SLS as an objective parameter
in the comprehensive evaluation of patients with knee OA.
