[Clinical study of exercise rehabilitation and gait analysis during the perioperative period of lumbar percutaneous transforaminal endoscopic discectomy].

OBJECTIVE:To explore the clinical effect of exercise rehabilitation during perioperative period on residual pain, gait and activities of daily living (ADL) in patients with lumbar spinal stenosis (LSS) after lumbar percutaneous transforaminal endoscopic discectomy(PTED). METHODS:The clinical data of 48 patients with LSS underwent PTED from December 2015 to December 2016 were retrospectively analyzed. Patients were divided into observation group and control group according to different rehabilitation patterns, being 24 cases in each group. The patients of observation group received exercise rehabilitation and the patients of control group received conventional rehabilitation. Visual analogue scale(VAS), Oswestry Disability Index (ODI) and the ratio of supporting phase were recorded before operation and 12 days, 6 months after operation. The correlation between the ratio of supporting phase and VAS, ODI was analyzed. RESULTS:The ratio of supporting phase of observation group was significantly higher than that of control group at 12 days after operation(P<0.05). The VAS and ODI in observation group were significantly lower than that of control group at 6 months after operation(P<0.01). There was no correlation between the ratio of supporting phase and ODI or VAS in two groups (P>0.05). CONCLUSIONS:Lumbar percutaneous transforaminal endoscopic discectomy combined with exercise rehabilitation during the perioperative period can release or eliminate postoperative residual pain, improve gait balance, enable activities of daily living, and has a positive effect in patients with lumbar spinal stenosis.
