STUDY DESIGN: A cross-sectional observational design study was conducted to determine lumbar repositioning error in 15 subjects who had @entity1643 with a clinical diagnosis of lumbar segmental instability and 15 asymptomatic @entity1 . OBJECTIVE: To determine whether individuals with lumbar segmental instability have a decreased ability to reposition their lumbar spine into a neutral spinal position. SUMMARY OF BACKGROUND DATA: Proprioception of the lumbar spine has been investigated in individuals who have @entity1643 with variable results. The testing procedure's lack of sensitivity and the nonhomogeneity of groups may be responsible for the conflicting findings. METHODS: Repositioning accuracy of the lumbar spine was assessed using the 3Space Fastrak to determine error in 15 @entity1 with lumbar segmental instability and 15 asymptomatic subjects. The @entity1 were assisted into a neutral spinal sitting posture and then asked to reproduce this position independently over five trials separated by periods of relaxed full lumbar flexion. RESULTS: Lumbosacral repositioning error was significantly greater in @entity1 with lumbar segmental instability than in the asymptomatic group (t[28] = 2.48; P = 0.02. There also was a significant difference between the groups at each individual sensor. CONCLUSIONS: The results of this study indicate that individuals with a clinical diagnosis of lumbar segmental instability demonstrate an inability to reposition the lumbar spine accurately into a neutral spinal posture while seated. This finding provides evidence of a @entity2649 proprioceptive awareness among this population.
