A new real-time visual assessment method for faulty movement patterns during a jump-landing task.
OBJECTIVE
Determine the interrater reliability of a new real-time assessment of faulty movement patterns during a jump-landing task.


METHODS
Interrater reliability study.


METHODS
Human movement laboratory.


METHODS
50 healthy females.


METHODS
Assessment included 6 items which were evaluated from a front and a side view. Two Physical Therapy students used a 9-point scale (0-8) to independently rate the quality of movement as good (0-2), moderate (3-5), or poor (6-8). Interrater reliability was expressed by percent agreement and weighted kappa.


RESULTS
One examiner rated the quality of movement of 6 subjects as good, 34 subjects as moderate, and 10 subjects as poor. The second examiner rated the quality of movement of 12 subjects as good, 23 subjects as moderate, and 15 subjects as poor. Percent agreement and weighted kappa (95% confidence interval) were 78% and 0.68 (0.51, 0.85), respectively.


CONCLUSIONS
A new real-time assessment of faulty movement patterns during jump-landing demonstrated adequate interrater reliability. Further study is warranted to validate this method against a motion analysis system, as well as to establish its predictive validity for injury.
