Abstract

Purpose: The aim of this study was to investigate and compare the risk factors focusing on the neck and lower back between general workers (GW) and mild intellectual disability workers (MIDW) in the automobile manufacturing industry. Methods: A total of 32 participants were required for this study design to achieve 80% power, 0.9 effect size, and an alpha level of 0.05. Each group consisted of 16 subjects, including GW and MIDW. Pain levels in the neck and lower back were measured for all participants using the visual analog scale (VAS). A dual digital inclinometer was used to measure the range of motion (ROM) in the neck and lower back three times, and the average was used for analysis. The independent t-test was used to compare between the wo groups. Cohen's d effect analysis was employed to determine the effect size. The significant level was set at 0.05. Results: In the MIDW, neck pain was significantly higher, and left cervical flexion was significantly decreased compared with the GW. There was no significant difference in lower back pain between the MIDW and GW. However, both lumbar flexion and extension, as well as lateral flexion, were significantly reduced in the MIDW compared with the GW. Conclusion: This study reveals that MIDW working in the automobile manufacturing industry have a greater risk of neck pain, limitation in left cervical flexion, and overall restriction in the ROM of the lower back compared with GW.
