The aim of the study was to investigate changes in quality of life measures in patients who have undergone an intensive exercise program after a single level microdiskectomy. A 12-week periodized exercise program of lumbar extensor strength and endurance training, and mat and upright therapeutic exercises were administered. Quality of life was measured with the Short Form 36 (SF-36). Measurements were taken 4-6 weeks postsurgery and following completion of the 12-week intervention program. Since some participants selected physical therapy apart from the study, analyses were performed for both an as-randomized (two-group) design and an as-treated (three-group) design. In the two-group analyses, exercise and education yielded a greater increase in SF-36 scales, role physical (17.8 vs. 12.1) and bodily pain (13.4 vs. 8.4), and the physical component summary (13.2 vs. 8.9). In the three-group analyses, post-hoc comparisons demonstrated that exercise and education resulted in a greater increase in the SF-36 scales, physical function (10.4 vs. 5.6) and bodily pain (13.7 vs. 8.2), and the physical component summary (13.7 vs. 8.9) in comparison to usual physical therapy.
The study found that an intensive, progressive exercise program combined with education increases quality of life in patients who have recently undergone lumbar microdiskectomy.
