Comparison between walking Test and Treadmill Test for intermittent claudication associated with lumbar spinal canal stenosis
European Spine Journal, 2015Co-Authors: Shinji Tanishima, Satoru Fukada, Toshiyuki Dokai, Yasuo Morio, Hiroyuki Ishii, Hideki NagashimaAbstract:Purpose To clarify the priorities of the walking Test and the Treadmill Test for intermittent claudication of lumbar canal stenosis. Methods The study population comprised 45 subjects, with a mean age of 72.6 years. An investigator walked with the subjects during the walking Test or watched the subjects walking on the Treadmill machine in the Treadmill Test. Results The pain scales became significantly worse after the walking Test. Ten patients who were diagnosed as root symptom type or cauda equine symptoms were subsequently diagnosed as mixed type by the walking Test. The numbers of patients who experienced muscle weakness that was not revealed at rest were eight with the walking Test and seven with the Treadmill Test. The numbers of patients who experienced sensory disturbance that was not observed at rest were seven with the walking Test and two with the Treadmill Test. Conclusions The walking Test detected significantly more symptoms that were not detected at rest than the Treadmill Test.

PREDICTIVE QUALITY OF Treadmill Test AND MRI AS PRE-SURGERY DIAGNOSTIC INSTRUMENTS IN LUMBAR SPINAL STENOSIS
2009Co-Authors: Thomas Barz, Markus Melloh, Harry Merk, L. Staub, F. KnöflerAbstract:Background context: Surgical treatment of lumbar spinal stenosis is one of the most frequent procedures in spinal surgery. Nevertheless, the predictive quality of instruments like Treadmill Test and MRI has not yet been clearly defined for the lumbar spinal stenosis. Purpose: Objective of this study was to verify correlations between Treadmill Test and MRI findings in the narrowest spinal segment. Methods: In a prospective study (EBM-level 3) 25 patients with inpatient treatment for lumbar spinal stenosis were investigated between 01/2005 and 06/2005. Exclusion criteria were a reduced walking capacity for other reasons (e.g. gonarthrosis). Treadmill Tests were performed following the protocol by Deen. Patients estimated their maximum walking distance before performing the Tests. Area of the dural sac, area of the neuroforamina and disc height at the dorsal margin were examined by MRI for the narrowest spinal segment. VAS and ODI were used as clinical assessment instruments. Outcome Measures: The median age of patients was 67 yrs (IQR 58–73 yrs) with 44 % females. The median distance reached in the Treadmill Test was 70 m (IQR 30–135 m), the median estimated maximum walking distance 200 m (IQR 100–300 m). In the narrowest spinal segment the median area of the dural sac was 91 mm2 (IQR 65–143 mm2), the median area of the neuroforamina 43 mm2 (IQR 36–51 mm2) and the median disc height 1,4 mm (IQR 0,9–2,5 mm). The median VAS was 7 (IQR 6,5–8) and the median ODI 33 (IQR 32–37). Results: The distance reached in the Treadmill Test correlated with the maximum walking distance estimated by the patients (Spearman’s rho=0,62, p=0,001), area of the dural sac (rho=0,54, p=0,006) and disc height (rho=0,45, p=0,03), but not with area of the neuroforamina and VAS. VAS correlated with the disc height (rho=−0,6, p=0,002), but with no other MRI findings. Conclusions: The distance reached in the Treadmill Test and MRI findings in the narrowest spinal segment predict the level of clinical symptoms. Possible reasons for the slightly limited predictive quality of MRI findings are that this study did not regard the time of development of the stenosis, that effects of multilevel stenosis were not considered, and that MRI findings in lying position without lordosis might differ from findings in standing position. However, the Treadmill Test is a valid and highly practicable pre-surgery diagnostic instrument in lumbar spinal stenosis.

The diagnostic value of a Treadmill Test in predicting lumbar spinal stenosis
European Spine Journal, 2008Co-Authors: Thomas Barz, Christian Roeder, Franz-georg Smiszek, Jean-claude Theis, Jörn Lange, Markus Melloh, Lukas P. Staub, Harry MerkAbstract:Lumbar spinal stenosis is a frequent indication for spinal surgery. The predictive quality of Treadmill Testing and MRI for diagnostic verification is not yet clearly defined. Aim of the current study was to assess correlations between Treadmill Testing and MRI findings in the lumbar spine. Twenty-five patients with lumbar spinal stenosis were prospectively examined. Treadmill Tests were performed and the area of the dural sac and neuroforamina was examined with MRI for the narrowest spinal segment. VAS and ODI were used for clinical assessment. The median age of the patients was 67 years. In the narrowest spinal segment the median area of the dural sac was 91 mm2. The median ODI was 66 per cent. The median walking distance in the Treadmill Test was 70 m. The distance reached in the Treadmill Test correlated with the area of the dural sac (Spearman’s ρ = 0.53) and ODI (ρ = −0.51), but not with the area of the neuroforamina and VAS. The distance reached in the Treadmill Test predicts the grade of stenosis in MRI but has a limited diagnostic importance for the level of clinical symptoms in lumbar spinal stenosis.

THE DIAGNOSTIC VALUE OF A Treadmill Test IN PREDICTING LUMBAR SPINAL STENOSIS
2009Co-Authors: Markus Melloh, Christian Roeder, Thomas Barz, Lukas P. Staub, P. Reiger, Emin Aghayev, Thomas Zweig, Jean-claude TheisAbstract:Introduction: Lumbar spinal stenosis is a frequent indication for spinal surgery. The predictive quality of Treadmill Testing and MRI for diagnostic verification is not yet clearly defined. The aim of our study was to assess correlations between Treadmill Testing and MRI findings in the lumbar spine. Methods: Patients with lumbar spinal stenosis who had been admitted for surgical treatment by means of decompression with or without stabilisation were prospectively examined. We included patients with lumbar spinal stenosis as defined by clinical symptoms like low back and/or leg pain, which increased when walking, and by the area of the dural sac examined by MRI. We excluded patients with clinically manifest peripheral arterial disease, polyneuropathy or musculoskeletal impairments compromising the ability to walk. Treadmill Tests were performed using the standardized Testing protocoll by Deen at a speed of 0.5 m/sec without inclination. After the onset of symptoms (pain, weakness or dysaesthesia), each patient decided when to end the Test. The area of the dural sac and neuroforamina was examined with MRI for the narrowest spinal segment. ODI and VAS were used for clinical assessment. Results: 25 patients were included with a median age of 67 years (Interquartile range IQR 60–72 yrs). In the narrowest spinal segment the median area of the dural sac was 91mm2 (IQR 67–135 mm2). The median ODI was 66 percent (IQR 64–72 percent). The median walking distance in the Treadmill Test was 70 m (IQR 30–130 m). The distance reached in the Treadmill Test correlated with the area of the dural sac (Spearman’s rho=0.53) and ODI (rho=0.51), but not with the area of the neuroforamina and VAS. Discussion: The Treadmill Test helps objectifying pre- and postsurgical clinical complaints and verifying a lumbar spinal stenosis by creating a situation of dynamic strain. Moreover, the Treadmill Test lets the patient experience his own physical limits and enables the examiner to attain a replicable postoperative assessment. The distance reached in the Treadmill Test predicts the grade of stenosis in MRI but has a limited diagnostic importance for the level of clinical symptoms in lumbar spinal stenosis.
