The Effect of Corset on Walking Time in Lumbar Spinal Stenosis
(ORTADOGU AD PRES & PUBL CO, 2009) Levendoglu, Funda; Oguz, Hasan; Polat, Esra; Bodur, Said
Objective: To investigate the quantitative effects of lumbar corset used in lumbar spinal stenosis (LSS) on walking time. Material and Methods: The study population comprised 70 LSS patients with a mean age (+/- SD) of 59.23 +/- 5.90 years. The equipment included a treadmill, unloading station and lumbar corsets. All patients were made to walk on a treadmill with 0-degree inclination at a speed of 1.2 km/h. During this walk, a system was available that could reduce the body weight by 20 or 25%. The patients walked five times as follows: without corset, with elastic woolen corset, with lumbar corset and with either 20 or 25% reduction in body weight. Symptom initiation time (SIT), and total walking time (TWT) were recorded. Statistical evaluations were performed with the software program SPSS 11.0. Results: As a result of walking with lumbar corset SIT and TWT were significantly longer compared to walking without corset (p < 0.001). The use of lumbar corset had a similar effect to that of 20% body weight reduction and lengthened the total walking time by reducing mechanical weight bearing. Conclusion: Lumbar corset increases SIT and TWT in patients with lumbar spinal stenosis. It is beneficial for symptoms similar to that obtained by 20% body weight reduction.
