From the Guidelines

Environmental enrichment has a positive effect on reducing chronic pain, depression, and anxiety by promoting neuroplasticity and improving functional recovery, and its incorporation into standard pain management programs is recommended. The use of environmental enrichment in pain management has been shown to be effective in improving analgesia quality, reducing analgesic use, and enhancing patient recovery and quality of life 1. This approach involves providing a stress-free environment that facilitates a multidimensional sensory experience, enhancing activities such as exercise and social interactions. Examples of environmental enrichment interventions that may help with pain management include yoga, meditation, reading, board games, and crafting 1.

Key Benefits of Environmental Enrichment

  • Improves functional recovery and reduces stress and depression levels
  • Enhances activities such as exercise and social interactions
  • Provides a stress-free environment that facilitates a multidimensional sensory experience
  • Can be used in conjunction with standard pain management programs, such as Enhanced Recovery After Surgery (ERAS) programs
  • May have an additive effect to the benefits provided by ERAS, with further enhancement of patient recovery and quality of life

Implementation of Environmental Enrichment

The incorporation of environmental enrichment into standard pain management programs is unlikely to be difficult or expensive 1. Clinically, combining environmental enrichment with proposed and established clinical protocols or pathways in pain management may enable maximal benefits to be derived 1. Using multiple different environmental enrichment activity modalities together in pain management may also further enhance its benefits and advantages. However, more clinical research is needed to fully understand the effects of environmental enrichment in humans, as the current evidence is mainly preclinical 1.

Potential Limitations and Future Directions

While the evidence for environmental enrichment is promising, there are limitations to translating preclinical models to humans, including differences in "standard conditions" in animal models, variability in environmental enrichment protocols, and species-specific traits that cannot be adequately emulated 1. Further research is needed to address these limitations and to fully understand the potential benefits and drawbacks of environmental enrichment in clinical pain management.

From the Research

Effect of Environmental Enrichment

The effect of environmental enrichment (EE) has been studied in various contexts, including animal care and human rehabilitation.

  • EE has been shown to have a positive impact on brain and cognitive functions, particularly in animal models of neurodegenerative diseases 2.
  • Studies have demonstrated that EE can improve cognitive functions and reduce anxiety-related behaviors across the lifespan 2.
  • In humans, EE has been used as a means to enhance brain plasticity mechanisms and improve behavioral function, particularly in post-stroke rehabilitation 3.
  • Virtual reality (VR)-based environmental enrichment has also been explored as a potential tool for improving cognition and mental wellbeing in older adults with mild cognitive impairment and mild dementia 4.
  • In animal care, EE has been used to improve well-being and reduce stereotyped behaviors, with studies demonstrating a positive correlation between interest behaviors and interactive behaviors in animals provided with enrichment objects 5.

Key Findings

  • EE has been widely used in laboratory settings, but its application in clinical settings is still limited due to various factors, including the lack of standardization and understanding of the underlying mechanisms 3.
  • The use of EE in animal care requires careful consideration of the animals' individual behavioral profiles and social context 5.
  • VR-based environmental enrichment has shown promise as a feasible and potentially effective tool for supporting older adults with mild cognitive impairment and mild dementia 4.
  • Further research is needed to fully understand the effects of EE and to address the gaps in knowledge that currently limit its application in clinical settings 6, 3.
