Objective : To evaluate the therapeutic effects of the new mobilization device (NMD) on clinical outcomes of chronic non-specific low back pain (CNLBP) patients.
Design : Randomised, double-blind, controlled clinical trial at baseline and after intervention.
Physical therapy outpatient clinic of K. University hospital.
Participants (or Animals, Specimens, Cadavers) : 24 participants (11 men and 13 women; 44.7 ± 11.4y) with diagnosed chronic nonspecific low back pain were randomly divided into 2 groups: NMD group (n=12, 5 men and 7 women; 47.3 ± 13.1y)and SE group (n=12, 6 men and 6 women; 42.1 ± 9.2y).
The NMD group trained sling exercises, including new mobilization device, for 40 minutes on the lumbar pain site for four weeks twice a week. The SE Group only did sling exercises in the same way.
Main Outcome Measure(s) :
The primary outcomes were pain intensity (numeric pain rating scale [NRS] score) and lumbar spine range of motion (modified-modified Schober’s flexion and extension test score and universal goniometer measurement). The secondary outcomes were low back disability (roland morris scale score) and the participant’s perceived treatment benefit (global perceived effect [GPE]). Outcomes were measured before and after 4 weeks’ intervention.
Results : NMD group showed significant differences in all clinical outcomes except Schober’s flexion (pt=3.287, p=0.003) and increased lateral flexion (left: t=−3.480, p=0.003; right: t=−2.284, p=0.040) and GPE than SE group.
Compared with sling exercise alone, the newly developed mobilization device with sling exercise effectively increased lumbar spine joint flexibility, especially in extension and lateral flexion. We recommend this device for CNLBP patients with joint stiffness in the lumbar region. Future studies should include different manual techniques and follow-up results.
