Abstract
Objective: To investigate the use of visually rated movement quality in a group including those with a history of intra-articular knee injury. Design: Historical cohort study. Setting: Laboratory. Participants: A total of 115 youth and young adults (62 previously injured). Main outcome measures: Inter-rater agreement for ratings of movement quality during single limb squat and vertical drop jump (VDJ) were assessed. Odds ratios were calculated to determine if the history of knee injury was associated with greater odds of poor movement quality. The difference in knee:ankle separation ratio between the injured and uninjured groups was compared. Results: Rater agreement was moderate to excellent (κ = 0.55 to 0.93). Comparing the injured and uninjured limb in previously injured participants or injured participants to matched uninjured controls, there was no significant difference in the proportion of good versus poor movement ratings (diff = 0% to 10%; p ≥ 0.23). Prior history of knee injury did not increase the odds of poor movement quality during the VDJ (OR 0.91; 95% CI 0.41 to 2.03) or single leg squat (OR 1.04; 95% CI 0.38 to 2.85) and there was no significant difference in the knee:ankle separation ratios (mean diff −0.03; p = 0.30). Conclusion: Visual rating of movement in individuals with and without a history of knee injury is reliable. A history of knee injury does not increase the likelihood of poor visually rated movement quality.
