Computer users are at risk in terms of musculoskeletal disorders. It is known that ergonomics training prevents short-term injuries to the musculoskeletal system, but its long-term effect is unknown.
The aim of our study was to investigate the effect of receiving ergonomics training in undergraduate instruction on posture during computer usage.
The present study included 27 individuals who had received training previously and 58 individuals who had not received any training. Their posture was evaluated with Rapid Upper Limb Assessment (RULA) and Musculoskeletal Diseases in Computer Users Frequency and Risk Factors Screening Form (MCFRF).
The percentage of pain experienced at least once in four weeks was much higher in the untrained than the trained group. The RULA scores were 3.7 ± 2.1 and 3.3 ± 0.8 points for the lower body and upper extremity for the trained group, and 4.2 ± 2.2 and 3.9 ± 0.9 points for the lower body and upper extremity, respectively, for the untrained group. The MCFRF scores were 1.9 ± 1.0 and 1.7 ± 1.0 points for the lower body and upper extremity, respectively, for the trained group, and 1.6 ± 1.3 and 1.6 ± 0.8 points for the lower body and upper extremity for the untrained group.
According to RULA scores, training on ergonomics was effective in reducing the risk level of musculoskeletal disorders. MCFRF scores showed that ergonomics training had no effect on posture during computer usage. Nevertheless, MCFRF evaluates only posture and does not calculate approximate forces that body parts were exposed to. Thus, these areas of MCFRF required improvement. Our study emphasized the importance of the long-term effects of ergonomics training for preventive purposes before musculoskeletal problems manifest.
计算机用户存在肌肉骨骼疾病方面的风险。已知人体工程学培训可预防肌肉骨骼系统的短期损伤，但其长期效果尚不清楚。
我们研究的目的是调查在本科教学中接受人体工程学培训对计算机使用时姿势的影响。
本研究包括27名先前接受过培训的个体和58名未接受过任何培训的个体。使用快速上肢评估（RULA）和计算机用户肌肉骨骼疾病频率及风险因素筛查表（MCFRF）对他们的姿势进行评估。
未受过训练的组中四周内至少经历一次疼痛的百分比远高于受过训练的组。受过训练的组下半身和上肢的RULA评分分别为3.7±2.1分和3.3±0.8分，未受过训练的组下半身和上肢的RULA评分分别为4.2±2.2分和3.9±0.9分。受过训练的组下半身和上肢的MCFRF评分分别为1.9±1.0分和1.7±1.0分，未受过训练的组下半身和上肢的MCFRF评分分别为1.6±1.3分和1.6±0.8分。
根据RULA评分，人体工程学培训在降低肌肉骨骼疾病风险水平方面是有效的。MCFRF评分显示人体工程学培训对计算机使用时的姿势没有影响。然而，MCFRF仅评估姿势，并未计算身体部位所承受的近似力。因此，MCFRF的这些方面需要改进。我们的研究强调了在肌肉骨骼问题出现之前，出于预防目的进行人体工程学培训长期效果的重要性。
