Exercises involving the lumbar muscles are very
important in the prevention and intervention of LBP. The
McKenzie lumbar muscle strength reinforcement and lumbar
stabilization exercises strengthen the lumbar muscles and
reduce LBP7–9). Decreased reposition sense due to decreased
sensory ability is a problem for spinal stability because of
deep muscle imbalance and proprioceptive problems after
PLIF, and some studies have investigated whether lumbar
stabilization exercises increase spine proprioception10, 11).
However, few studies have compared the efficacy of
traditional exercise rehabilitation (ER), extension exercise
rehabilitation (EER), and lumbar stability exercise rehabilitation
(SER) using MedX (MedX Inc., USA) devices after
PLIF.
Therefore, this study compared the differences in pain,
disability, and muscle strength before and after ER and EER
performed on MedX devices, and SER using the method of
O’Sullivan (2000). We also discuss more efficient exercise
methods for reducing pain and improving function after
PLIF.
