Globally, non-specific low back pain (NSLBP) is a common cause of morbidity in all people including physiotherapy students. However, no study has investigated the problem among undergraduate physiotherapy students in Zimbabwe. This study was conducted, therefore, to provide evidence of the prevalence, clinical characteristics and consequences of recurrent NSLBP among undergraduate physiotherapy students at the University of Zimbabwe.
The final sample had 90 participants, giving a study response rate of 97.8%. The median age of the participants was 22 years. The lifetime prevalence of NSLBP was 56.7% (n = 51) and the mean age of onset for NSLBP was 19.7 years (SD = 1.64 years). The 12-month prevalence of recurrent NSLBP was 38.9% (n = 35). Of the 35, 20 (57.1%) experienced at least three episodes in the last 12 months. Each episode lasted for 1-7 days in most participants (n = 31, 88.6%). The mean intensity of recurrent episodes was 3.37 (SD = 1.43) measured on Visual Analogue Scale. Only 7 (20%) experienced at least one functional limitation due to recurrent NSLBP. Additionally, only 2 (5.7%) sought medical treatment for the pain. However, 6 (17.1%) had to be absent from the university secondary to recurrent NSLBP.
在全球范围内，非特异性下腰痛（NSLBP）是包括物理治疗专业学生在内的所有人发病的常见原因。然而，尚无研究调查津巴布韦本科物理治疗专业学生中的这一问题。因此，本研究旨在提供津巴布韦大学本科物理治疗专业学生复发性NSLBP的患病率、临床特征及后果的证据。
最终样本有90名参与者，研究应答率为97.8%。参与者的中位年龄为22岁。NSLBP的终生患病率为56.7%（n = 51），NSLBP的平均发病年龄为19.7岁（标准差 = 1.64岁）。复发性NSLBP的12个月患病率为38.9%（n = 35）。在这35人中，20人（57.1%）在过去12个月中经历了至少三次发作。大多数参与者（n = 31，88.6%）每次发作持续1 - 7天。复发性发作的平均强度在视觉模拟量表上测得为3.37（标准差 = 1.43）。只有7人（20%）因复发性NSLBP经历了至少一次功能受限。此外，只有2人（5.7%）因疼痛寻求医疗治疗。然而，6人（17.1%）因复发性NSLBP不得不缺课。
