STUDY DESIGN: This investigation compared the gait of revision and primary @entity85 @entity1 about to undergo surgical reconstruction with that of a group of able-bodied controls. OBJECTIVES: The hypothesis of the study was that both @entity1 groups would have significantly compromised gait, spine motion, and gait endurance compared with the able-bodied group. SUMMARY OF BACKGROUND DATA: There is a population of adults with degenerative changes superimposed on @entity2112 who present for reconstructive spinal surgery (primary @entity1 ). There is another group of adults who have already had @entity85 surgery and present for revision surgery (revision @entity1 ). METHODS: Twenty-seven @entity1 were recruited (8 primary, 13 revision, 6 able-bodied controls). A typical gait analysis was performed. Walking endurance was estimated from a submaximal graded treadmill exercise test. Three motion variables describing the orientation of the shoulders with respect to the pelvis in the three principal planes of the body were determined. Also, gait speed, stride length, cadence, and step width were calculated. The variable for the endurance test was the length of time walked on the treadmill. RESULTS: Results for the revision group indicated a slower walking speed, greater sagittal plane trunk flexion, reduced range of motion in the coronal and transverse planes, and poorer endurance relative to age-matched controls. The primary group demonstrated a slower walking speed relative to age-matched controls. The revision group had poorer endurance scores relative to the primary group. CONCLUSION: This investigation is an objective report describing the compromised gait and walking endurance of adult @entity1 with @entity85 before spinal fusion surgery. Results supported subjective observations regarding the preoperative gait of these @entity1 and presented results difficult to observe in a clinical setting. The techniques appear useful in providing objective information regarding the gait abilities of these @entity1 .
