LBP, Low back pain
Low back pain (LBP) is a symptom common to all age groups worldwide, primarily among the working population [Chronic LBP is defined as LBP persisting for at least three months after onset [Thus, there is a need for interventions to prevent NSLBP in occupational health settings. These interventions should not require treatment at a medical institution or special equipment. Accordingly, we assumed that a quick and easy exercise program could become a realistic LBP preventive strategy that is compatible with a busy workstyle. Thus, we developed a quick simple exercise program incorporating stretching and a combined exercise for the lower back. The program can be performed in three minutes and we verified its effects among workers in the manufacturing industry. Sitting or standing for a long time were recognized potential risk factors for LBP in the manufacturing industry [Interventions for LBP typically consist of education provided by a doctor or physical therapist. In previous research, interventions have typically been time-consuming, for example combining information booklets and sessions with a physical therapist for an intervention taking approximately four hours [
