ObjectiveTo investigate the correlation between the level of outdoor activity before operation and efficacy after 3 and 12 months of decompression in patients with lumbar spinal stenosis(LSS).
MethodsThe clinical data of 99 LSS patients treated with surgical decompression were retrospectively analyzed.According to the outdoor activities before operation, the patients were divided into the outdoor activity group(44 cases with regular participating in high intensity or moderate level of outdoor activities) and non-outdoor activity group(55 cases with mild outdoor activity or inactive sedentary state).The demographic data and prognosis after 3 and 12 months of operation in two groups were analyzed, and the correlation between two groups was studied.
ResultsCompared with the outdoor activity group, the daily smoking rate and non-insulin dependent type 2 diabetes mellitus in non-outdoor activity group were higher(P < 0.05).The postoperative effects in two groups were better(P < 0.01), the improvement of VAS score and ODI index of leg pain in non-outdoor activity group were significantly lower than those in outdoor activity group(P < 0.05), and the difference of the treatment effect after 12 months of operation was not statistically significant(P>0.05).The results of multivariate analysis showed that the preoperative low back pain in patients with depression, BMI for 25.0-29.9, BMI for 30.0-34.9 and BMI for ≥ 35.0 kg/m2 were more severe(P < 0.05).The preoperative dysfunction and quality of life in patients with outdoor activities were lighter and higher, respectively(P < 0.05 to P < 0.01).The ODI index in LSS patients with outdoor activities were significantly improved after 12 months of decompression surgery(P < 0.05).
ConclusionsThe early recovery time in LSS patients without outdoor activities before lumbar decompression surgery is long, but the desired outcome can be achieved after 12 months of surgery.
