Rigid leukotape applied to the skin of the trunk dorsum, superficial to the lumbar paraspinals, has been shown to reduce lumbar flexion in repetitive lifting, with the potential to reduce the risk of injury in jobs requiring the handling of material. It is unclear which mechanism underpins this reduction, and whether a tape with more elastic properties (i.e., kinesio tape) can yield similar results. In this study, twelve participants were randomly allocated into two groups, and practiced a repetitive lifting task with either leukotape or kinesio tape applied to the skin of their trunk dorsum. The participants also performed a sagittal plane repositioning task to assess changes in lumbar proprioception. The results showed a small reduction in lumbar flexion in the kinesio tape group and a moderate reduction in the leukotape group, and suggested a reduction in repositioning errors in the kinesio tape group only. We suggest that leukotape may correct the movement and improve performance during a flexion-based task, while kinesio tape may improve lumbar proprioception and promote learning. These results have implications for the choice and use of wearable textiles aiming to reduce injury risks in the manual handling industry.
