Background: Alcohol use disorder (AUD) is characterized by severe dependence on alcohol, poor impulse control, and heightened attention to alcohol‐related cues. Attention bias modification (ABM) retrains individuals to distract attention from alcohol‐related cues. This study investigates the effect of combining ABM with cognitive behavioral therapy (CBT) to reduce relapse risk and cravings in male patients with AUD. Methods: A quasi‐randomized controlled trial was conducted among male inpatients diagnosed with AUD. Participants were divided into an intervention group receiving ABM in addition to CBT and a control group receiving CBT with a placebo intervention. The primary outcomes—risk of relapse and craving levels—were measured using the Alcohol Relapse Risk Scale (ARRS) and a visual analog scale (VAS), respectively. Participants underwent weekly sessions over 6 weeks, and outcomes were analyzed using generalized linear models (GLMs). Results: The analysis did not reveal significant interactions between the intervention group and time for ARRS scores and craving levels. Both groups experienced a reduction in relapse risk and cravings. However, there was no significant difference between the ABM + CBT and CBT‐only groups. Conclusions: Although the combined ABM and CBT intervention did not result in statistically significant reductions in relapse risk and cravings compared to CBT alone, the overall reduction in these outcomes in both groups highlights the effectiveness of CBT in treating AUD. Future studies should use naturalistic settings and tailor the intervention to individual cognitive profiles.

Long-term repetitive movements, such as opening and closing scissors, increase strain on muscles and joints. Amplitude probability distribution function (APDF) analysis of surface electromyogram (sEMG) data was used to quantify the burden of muscle activity. We aimed to test the hypothesis that scissors with a power-support device assist repetitive thumb movements to reduce potential myoelectric activity. Twenty female university students who met the eligibility criteria performed a cutting experiment, with and without power-support device scissors. The primary outcome was a change in muscle load due to sEMG data that were analyzed using APDF, and the secondary outcomes investigated the occurrence of muscle fatigue and pain. The adductor pollicis muscle showed a significant decrease in muscle activity with power assistance. In addition, it was also found that fatigue and pain of the thumb and on the radial side of the forearm were significantly lower under the power-assisted conditions. The results of this study suggest that the assistive action of scissors with a power-support device compensate for muscle load on the thenar eminence. This may be used as a reference value to prevent the occurrence of hand disorders for hairdressers.

Hand fatigue commonly occurs in repetitive tasks, such as cutting with scissors, leading to discomfort, reduced productivity, and musculoskeletal disorders. Recent advances in assistive technology have introduced power-assisted scissors to reduce the muscular load. Pinching and grasping mainly involve the adductor pollicis muscles of the hand. Measuring the electromyographic (EMG) activity of these muscles provides valuable insights into the muscular effort required for such tasks. Studies have indicated that power-assisted devices can effectively reduce muscle strain and fatigue. However, research on the effect of power-assisted scissors on adductor pollicis muscle activity is limited. This study examines the differences in adductor pollicis muscle activity using power-assisted scissors versus traditional scissors. The experiment consisted of 20 participants performing a scissor manipulation task with and without power assistance. Frequency analysis of the adductor pollicis muscle EMG data indicated that scissors with power assistance significantly reduced muscle fatigue (95% confidence interval, 10.705 [4.523–19.751], p < 0.01, η² = 0.01). Understanding the efficacy of power-assisted scissors has significant implications for occupational health—particularly in professions that involve extensive manual cutting, such as tailoring and hairdressing. This study can contribute to the design of ergonomic tools that enhance comfort and reduce musculoskeletal disorder risks.
