Lumbar repositioning deficit in a specific low back pain population.

Study Design: A cross-sectional observational design study was conducted to determine lumbar repositioning error in 15 subjects who had chronic low back pain with a clinical diagnosis of lumbar segmental instability and 15 asymptomatic participants.

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 low back pain with variable results.
