“…The prevalence of patients with LBP and sciatica was 100%, 88.57%, and 93%, respectively (Lewis et al, 1987;Nguyen, 2014;Tran & Le, 2018). The onset time was mainly less than 12 months (39%) (Table 2), which was different from some studies with the onset time recorded as 91.67%, 65.2%, 56.66%, 42.85% (Duong, 2015;Nguyen, 2014;Tran & Le, 2018). The difference could be due to the patient's current knowledge; our study was conducted in 2019, and others were conducted in 2014, 2015, and 2018 respectively.…”
