Objective: To determine the effects of lumbar extension exercise
on strength, disability index, and pain scores in patients
after lumbar discectomy surgery.
Design: Prospective comparative study.
Subjects: Forty patients experiencing a herniated disc
at lumbar levels were divided into 4 subgroups for different
training frequencies: twice/week (group 1), once/week
(group 2), once/2 weeks (group 3), and no training (control).
Methods: After completing the initial 12-week training, all
subjects participated in a 12-week follow-up training.
Results: Groups 1 and 2 showed significant increases in
lumbar extension strength (26 Nm and 7 Nm, respectively),
while group 3 and the control group showed significant decreases
in lumbar extension strength. Groups 1 and 2 showed
significant decreases in disability index (1.4 and 0.8 Oswestry
Disability Index points, respectively), and group 1 showed
significant decreases in back and leg pain scores (both 0.5
units on a 10-cm visual analog scale).
Conclusion: Lumbar extension strength and disability index
improve with training frequencies of once and twice per
week, while back and leg pain improve with a training frequency
of twice per week. The clinical importance of these
improvements is questionable, as the scores were already
very low after the discectomy and the magnitude of absolute
improvements were small.
