Occupational Rehabilitation Is Associated With Improvements in Cognitive Functioning

Area of Science:

• Occupational health
• Rehabilitation medicine
• Cognitive psychology

Background:

• Workers on long-term sick leave often experience cognitive deficits, anxiety, depression, pain, and reduced work ability.
• Limited empirical data exists on the impact of occupational rehabilitation on cognitive and emotional functioning, with a lack of comprehensive objective testing.
• This study addresses the need to understand how occupational rehabilitation influences cognitive and emotional domains in this population.

Purpose of the Study:

• To assess changes in cognitive functioning (memory, attention, executive function) and emotional functioning (emotion recognition) among patients undergoing occupational rehabilitation.
• To evaluate the influence of a 28-day inpatient and outpatient occupational rehabilitation program on these functions.

Main Methods:

• A pre-post design was employed with 280 sick-listed workers undergoing occupational rehabilitation (mean duration 28 days).
• Rehabilitation included physical activity, cognitive behavioral therapy, and workplace collaboration.
• A control group of 70 healthy workers was used for comparison, with repeated measures ANOVA for analysis.

Main Results:

• The rehabilitation group showed significantly greater improvements in focused and sustained attention compared to the control group.
• Significant enhancements were observed in work ability and reductions in subjective health complaints, helplessness, pain, anxiety, and depression.
• Improvements in attention correlated with increased return-to-work self-efficacy, work ability, and reduced subjective health complaints.

Conclusions:

• Occupational rehabilitation effectively improved focused and sustained attention, work ability, and various health measures in sick-listed workers.
• This research is among the first to systematically examine cognitive and emotional changes during occupational rehabilitation.
• Clinical practice should leverage knowledge of attention improvements and consider interventions to further enhance memory, executive function, and emotion recognition.
