Abstract: Objective: To investigate the effects of pre-rehabilitation before hospitalization in older patients with posterior long-segment lumbar surgery. Methods: According to the admission date, eighty-one older patients who received posterior long-segment lumbar surgery from January 2020 to June 2021 were assigned to the control group (n=40) and the interventional group (n=41). Patients in the control group received routine preoperative preparation, while patients in the interventional group received pre-rehabilitation intervention before hospitalization besides the preoperative preparation. The results of a 6-Minute Walk Test, serum albumin, anxiety, back function, pain, and incidences of some common postoperative complications were compared between the two groups. Results: After the intervention, it was showed that the main effect difference and the time main effect difference of the 6-Minute Walk Test, serum albumin, anxiety, back function and pain of patients in the two groups were statistically significant (P<0.05). There was an interaction between the intervention factor and the time factor (P<0.05). The incidence of postoperative constipation in the interventional group was lower than that in the control group (P<0.05). There were no differences regarding the occurrence of postoperative Venous Thromboembolism, incision infection and lung infection between the two groups (P>0.05). Conclusion: Pre-rehabilitation before hospitalization can effectively improve the physiological and psychological functions of older patients with posterior long-segment lumbar surgery during the perioperative period, and reduce the dysfunction and pain of back.
