Effectiveness of slow motion video compared to real time video in improving the accuracy and consistency of subjective gait analysis in XXXX .

@entity235 @entity1273
Objective measures of @entity235 gait quality via force plates, pressure mats or kinematic analysis are considered superior to subjective gait assessment (SGA). Despite research demonstrating that SGA does not accurately detect @entity1273 , it remains the most commonly performed diagnostic test for detecting @entity1273 in @entity235 . This is largely because the financial, temporal and spatial requirements for existing objective gait analysis equipment makes this technology impractical for use in general practice. The utility of slow motion video as a potential tool to augment SGA is currently untested. To evaluate a more accessible way to overcome the limitations of SGA, a slow motion video study was undertaken. Three experienced veterinarians reviewed video footage of 30 @entity235 , 15 with a diagnosis of primary limb @entity1273 based on history and physical examination, and 15 with no indication of limb @entity1273 based on history and physical examination. Four different videos were made for each @entity235 , demonstrating each @entity235 walking and trotting in real time, and then again walking and trotting in 50% slow motion. For each video, the veterinary raters assessed both the degree of @entity1273 , and which limb(s) they felt represented the source of the @entity1273 . Spearman's rho, Cramer's V, and t-tests were performed to determine if slow motion video increased either the accuracy or consistency of raters' SGA relative to real time video. Raters demonstrated no significant increase in consistency or accuracy in their SGA of slow motion video relative to real time video. Based on these findings, slow motion video does not increase the consistency or accuracy of SGA values. Further research is required to determine if slow motion video will benefit SGA in other ways.
