Sensory Symptoms and effects on Health-related Quality of Life of Patients Undergoing Lumbar Spine Surgery

Background: Patients with lumbar degenerative spine diseases (LDSDs) commonly report sensory symptoms before and after lumbar spine surgery. Aim: To explore the changing patterns of sensory symptoms—namely pain, numbness, stinging, itching, and burning—and investigate the influences of sensory symptom changes on the health-related quality of life (HRQoL) of patients who experienced lumbar spine surgery. Methods: All sensory symptoms (i.e., pain, numbness, paresthesia) were measured using a visual analog scale. The Chinese versions of the Oswestry Disability Index, Pittsburgh Sleep Quality Index, Clinically Useful Depression Outcome Scale, and EuroQol-five dimensions (EQ-5D) Scale were used to assess patients 1 week prior to surgery and 6 weeks and 6 months after surgery. A generalized estimating equation was used for data analysis. Results: A total of 101 patients with mean age of 58.38 years were included. All sensory symptoms declined significantly over time (all p <. 05) with the exception of itching (feeling on toes and thighs). Patients experiencing moderate-to-severe pain had poorer QoL over time, even after controlling for other sensory symptoms and potential confounders. Conclusions: Sensory symptoms gradually declined after surgery, but itching symptom did not. Moderate-to-severe pain was the only sensory symptom that influenced HRQoL over time in patients with LDSDs.
