ABSTRACT
A prospective evaluation of patients with lumbar spinal stenosis undergoing operative treatment was performed using treadmill-bicycle functional testing as well as Oswestry and Visual Analog Pain scales for self-assessment. Thirty-two patients undergoing spinal stenosis decompression with and without a concomitant spinal fusion were prospectively evaluated, preoperatively and a minimum of 2 years postoperatively. Surgical treatment was demonstrated to produce significant improvement in walking ability, and to a lesser degree, in the ability to bicycle 2 years postoperatively. Improvement in patient function demonstrated on the Oswestry questionnaire correlated with decreased pain observed on the Visual Analog Pain scale. The treadmill-bicycle test appears to be a useful tool for the differential diagnosis of neurogenic claudication and may be used as an objective test of postoperative outcome.

BACKGROUND AND PURPOSE: The prescriptive validity of a treatment-oriented extension-mobilization category for patients with low back syndrome (LBS) was examined. SUBJECTS: Of a total of 39 patients with LBS referred for physical therapy, 24 patients (14 male, 10 female), aged 14 to 50 years (means = 31.3, SD = 11.6), were classified as having signs and symptoms indicating treatment with an extension-mobilization approach. The remaining subjects were dismissed from the study. Patients in the extension-mobilization category were randomly assigned to either an experimental (treatment) group (n = 14) or a comparison group (n = 10). METHODS: The experimental and comparison group subjects were treated with either mobilization and extension (a treatment matched to the category) or a flexion exercise regimen (an unmatched treatment). Outcome was assessed with a modified Oswestry Low Back Pain Questionnaire administered initially and at 3 and 5 days after initiation of treatment. Data were analyzed with a 2 x 3 (treatment group x treatment period) analysis of variance. RESULTS: The subjects' rate of improvement, as indicated by the Oswestry questionnaire scores, was dependent on the treatment group to which they were assigned. Subjects treated with extension and mobilization positively responded at a faster rate than did those treated with a flexion-oriented program. CONCLUSION AND DISCUSSION: This study illustrates that a priori classification of selected patients with LBS into a treatment category of extension and mobilization and subsequently treating the patients accordingly with specified interventions can be an effective approach to conservative management of selected patients.

The purpose of this study was to determine the relationship between direction of lateral lumbar shift (LLS) and 1) the occurrence of symptoms during the side-bending movement test and 2) the location of symptoms in patients with low back pain syndrome (LBS). Twenty-four patients with LBS (17 male, 7 female) with an observable LLS were studied. Side-bending movement tests were performed bilaterally, and the results were recorded as positive if symptoms occurred during the movement. The location of symptoms (right side or left side) was obtained from the patient history. Use of the chi-square statistic revealed a statistically significant relationship between the direction of the LLS and the direction of the positive side-bending movement test. Seventeen tests (71%) were positive to the contralateral side of the LLS, and 5 (21%) were positive to the ipsilateral side. Two tests (8%) were negative in both directions. There was no significant relationship between the side of symptoms and the direction of the LLS. The determination of presence and direction of an LLS is necessary in certain physical therapy management approaches. Pain or restricted side-bending movement has been used to confirm the presence of an LLS. This study confirms the clinical usefulness of the side-bending movement test for determining the presence and direction of an LLS.
