Investigating approach/avoidance tendencies in male AUD patients through a gait initiation task: An exploratory...

Area of Science:

• Neuroscience
• Clinical Psychology
• Motor Control

Background:

• Alcohol Use Disorder (AUD) is a significant public health concern.
• Understanding approach/avoidance tendencies is crucial for relapse prevention.
• Gait initiation and posturography offer novel insights into AUD-related behaviors.

Purpose of the Study:

• To investigate approach/avoidance tendencies in male AUD patients using a gait initiation task.
• To assess the predictive value of motor responses for relapse or abstinence post-detoxification.
• To explore the utility of posturography in identifying relapse risk.

Main Methods:

• Seventy-four male participants (47 AUD, 27 controls) were recruited.
• Participants responded to alcohol-related, erotic, and neutral visual stimuli.
• Reaction times and postural micromovements during gait initiation were recorded.

Main Results:

• Relapsers demonstrated slower reaction times to alcohol cues compared to abstainers.
• Increased postural instability (micromovements) was observed in relapsers when viewing alcohol stimuli.
• Significant Stimuli × Group interactions were found for both reaction times and postural measures.

Conclusions:

• Relapsers exhibit distinct motor responses to alcohol cues, indicating heightened relapse risk.
• Delayed reaction times and increased postural instability are potential early indicators of relapse.
• Posturography shows promise as a clinical tool for alcohol detoxification programs.
