Background: Lumbar canal stenosis (LCS) is a painful and potentially disabling condition in older adults. Neurogenic claudication is usually caused by degenerative LCS, which refers to age-related degenerative narrowing of the spinal canals. The previous study shows that flexion-based exercise program has positive outcome in LCS in older adults. Based on the observation that cycling on stationary bicycle dose not elicits pain in people with neurogenic claudication. Hence the present study was undertaken to find out the combined effect of flexion exercises along with stationary bicycling on neurological claudication in LCS.
Methodology: An experimental study was carried on 20 patients of age >50 years diagnosed with LCS. They were randomly divided into two groups. Group A was given flexion exercises along with stationary bicycling and group B was given flexion exercises only. Both the groups were given hot pack and intermittent lumbar traction. Visual analogue scale (VAS) on 6-minute walk test and Modified Oswestry disability index score (M.O.D.I) for functional disability values were taken at baseline then on alternate day for 4 weeks.
Result: After 4 weeks of treatment, the mean of VAS on 6 min walk test for group A and group B was 3.9 and 5.2respectively, which was statistically significant (p<0.0329) whereas the mean of M.O.D.I. disability index for group A was 21.4 and for group B it was 34.4, this was also statistically significant, (P<0.0400).
Conclusion: Flexion exercises along with stationary bicycling are more effective in reducing neurological claudication symptom and improving functional status by decreasing disability of patients with LCS in comparison with flexion exercises only.
