Objective: The purposes of this study are to investigate effects of complex trunk motions including flexion/extension and lateral bending, and external load on perceived discomfort, and to develop a new complex trunk motion and external load classification scheme based on the perceived discomfort.
Background: Low back pain is one of the most frequently occurring diseases in daily life as well as industrial sites, which accounts for almost half of work-related musculoskeletal disorders in Korea. Quantification of postural stress for low back or trunk motions is needed for preventing low back pain. For doing this, the posture classification schemes such as RULA, REBA are frequently used. The schemes classify trunk motions into 4 or 6 categories according to motions of flexion and extension, and simply add 1 to their corresponding postural stress scores depending upon whether or not the trunk is twisting or laterally bending. This is very simple to assess complex trunk motions, but results in inaccurate trunk motion stress.
Method: An experiment for measuring perceived discomfort according to complex trunk motions and external load was conducted, in which trunk motions of flexion/extension and lateral bending, and external load were used as independent variables. Fifteen healthy male college students without histories of musculoskeletal disorders participated in the experiment, whose demographic data were as follows: Age - 24.0 ± 1.73 years; Stature - 174.8 ± 6.53cm; Body weight - 72.1 ± 8.41kg.
Results: ANOVA showed that single factors of flexion/extension, lateral bending, and external load affected significantly on the discomfort at α = 0.01. On the other hand, the interactions between independent variables were not significant. The effect of external load was much larger, while the effects of flexion/extension and lateral bending were similar. Based on the experimental results, a new classification scheme reflecting quantity of external load as well as complex trunk motions was developed.
Conclusion: The study investigated effects of complex trunk motions and external load on perceived discomfort, and developed a new classification scheme of complex trunk motion and external load.
Application: The results of this study are useful for more precisely assessing postural load according to complex trunk motions and external load, and can be adopted as a part of a new posture classification scheme or existing schemes.
